Abstract

The dynamics surrounding Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, are thoroughly examined in this paper. The study investigates key parameters, including the density of accretion flow particles at varying radial distances, which reveal detailed insights into the structure and stability of the inflowing material. The velocity field surrounding Sgr A* demonstrates the acceleration patterns within the accretion disk, significantly influenced by the gravitational potential of the black hole. The overall density profile of the Milky Way’s central region, derived from accretion rates, further emphasizes the unique low-accretion characteristics of Sgr A*. Gravitational modeling illustrates the potential distribution and its effects on accretion flow distribution, enhancing our understanding of how matter behaves under extreme gravitational forces. Through histogram analysis of image data, we map the density variations around Sgr A*, revealing high-density regions and potential hotspots. Additional image processing identifies and isolates Sgr A*, allowing for a focused examination of its immediate environment. Lastly, the color cluster analysis relative to chemical abundances provides insights into the elemental composition near Sgr A*, and 3D surface plots and heatmaps depict the spatial structure and intensity distribution of galaxy clusters. Collectively, these findings enhance our understanding of black hole accretion mechanics, the impact of gravitational and magnetic forces, and the broader galactic ecology surrounding Sgr A*.

Abstract

This study explores the spectrum analysis of celestial objects within the wavelength range of 1000 nm to 2400 nm, focusing on its application in understanding the chemical and thermal evolution of the universe. The emergence of light elements like hydrogen and helium was made possible by primordial nucleosynthesis, which took place not long after the Big Bang and provided vital evidence in favor of the Big Bang theory. The production of heavier elements in stars is known as stellar nucleosynthesis, and this process is thoroughly studied. The significant factor in the various nucleosynthetic processes placed within stars is temperature. The study also delves into the galactic chemical evolution, tracing the enrichment of elements like carbon, oxygen, and iron over time through repeated cycles of star formation and stellar death. The research highlights how temperature evolution in galactic chemical processes influences star formation and cooling mechanisms, impacting the overall chemical composition of galaxies. The spectrum analysis in the near-infrared range allows for the findings of these processes even in dust-enshrouded regions, offering deeper insights into stellar and galactic evolution. These findings contribute to a more comprehensive understanding of how the universe's chemical and thermal makeup has changed since its inception.

Abstract

Witness the universe evolve in real-time through interactions with galaxy clusters, and colossal structures. In this work, we aim to explore the role of energy distribution and density in disturbed galaxy clusters. The study evolution of energy and density in two-dimensional systems using large-scale numerical simulations. The continuity, momentum, and energy equations were solved in a finite difference time domain to employ magnetic and gravitational fields. The results show that the density distribution is highest in the core and peaks at radii external to this, within galaxy clusters. Meanwhile, the energy density is shown to be reduced at the core and maxima radially outwards where it reaches a maximum around the outer limit of densities. This correlation shows how this gradient in the density modifies its energy distribution. These findings are consistent with prior simulation studies and theoretical models. In conclusion, understanding the dynamics and evolution of galaxy clusters requires understanding density patterns and energy distribution.  More intricate simulations involving extra physical processes like dark matter interactions and magnetic fields should be a part of future efforts.

Abstract

The Sunspots, which are dark patches on the sun's surface associated with significant magnetic activity, vary in number and distribution throughout time and latitudes. Understanding these fluctuations is critical for forecasting space weather and studying solar dynamics. This study aims to examine the latitudinal variability of sunspot numbers from 2014 to the present, as well as relationships with latitude and time trends. Monthly sunspot numbers from 2014 onwards were investigated. Statistical techniques such as standard deviation, Pearson correlation coefficients, ANOVA, and geographic analysis were used to study the association between latitude and sunspot numbers. The investigation indicated a standard deviation of 44.01 for sunspot numbers, indicating high fluctuation over the study period. A slight positive association (0.05) between latitude and sunspot number was discovered, with a non-significant p-value of 0.548. However, a significant relationship between year and sunspot numbers was found (F-statistic = 105.98, p-value = 3.08e-55). Sunspot numbers fluctuated significantly between -20- and 20 degrees latitude, with peaks at -45 and -10 degrees. While sunspot numbers vary over time, their association with latitude is minor. The study highlights the solar cycle's main influence on sunspot activity. Future studies should investigate additional solar factors and expand the dataset to improve knowledge of sunspot dynamics and their implications for space weather forecasting.

Abstract

Geomagnetic storms, which were brought on by solar activity in the ionosphere and thermosphere, influence the dynamics of Earth's atmosphere. This study aims to provide a comprehensive understanding of the effects of geomagnetic storms on many components of Earth's atmosphere. After summarizing the causes and characteristics of geomagnetic storms, such as solar flares and coronal mass ejections, the paper looks at how these events impact Earth's atmospheric dynamics. It focuses on the effects of geomagnetic storms on wind patterns, atmospheric temperature and density variations, thermospheric heating, and ionospheric disturbances. The study shows significant differences in the electric field strength over the first ninety-six days of April 2022 and 2023. Following this point, the electric field's behavior shows distinct tendencies, with notable differences between the two years. In April 2022, there was a slower fluctuation in the electric field strength following the initial rapid period. It reached its pinnacle around day 104, after which it started to deteriorate. In this pattern, a minimum was observed around day 106. A distinct pattern, however, is seen in April 2023, with a minimum electric field strength recorded at day 110 dipping below -2V/m and a sudden increase to a maximum of roughly 2V/m by day 113. The observed relative variations in mean electric field strength further explain the differences between April 2022 and April 2023. A relative change of -385.86 V/m highlights significant differences in electric field intensity between the two years and highlights the dynamic nature of atmospheric and ionospheric processes. The components of the magnetic field investigation, which revealed relative changes for mean Bx, By, and Bz of -267.01%, -9366.67%, and 57.14%, respectively, are consistent with these results. Together, these results demonstrate the intricate relationships between solar activity, geomagnetic disturbances, and atmospheric dynamics.

Abstract

Radionuclides, both natural and man-made, are the primary causes of human radiation exposure. These radionuclides can dissolve in water, enter the body via drinking water, and harm human health. In this study, five samples were collected from the groundwater resources of Gambella town. The specific activities of 226Ra, 232Th, and 40K were determined in the samples using gamma-ray spectrometry and a high-purity germanium (HPGe) detector. The fatality cancer risk (FCR), lifetime fatality cancer risk (LFC), severe hereditary effects (SHE), and estimated lifetime hereditary effects (ELHE) in diverse samples. The findings show significant differences in FCR and LFC, implying that certain populations are more likely to get cancer. The SHE values, while lower, show the possibility of genetic consequences. ELHE ideals stress the need to address potential genetic repercussions in the long run. These findings are consistent with previous research, stressing the importance of continued monitoring and public health initiatives to reduce the dangers associated with radiation exposure. The study emphasizes the necessity of protection measures for vulnerable populations and ensuring long-term health results.

Abstract

This study investigates the recovery of dynamics of coronal dimmings across solar activity phase. Temperature distributions, magnetic field evolution, and plasma density influence developing core and secondary dimming zones in solar and astrophysical plasma situations. Using advanced simulation techniques, we modeled the evolution of plasma density and temperature, revealing significant temperature gradients and distinct density profiles.. The results show a marked decrease in plasma density at the core regions, surrounded by secondary dimming zones, consistent with observed phenomena in solar flares and coronal mass ejections (CMEs). Thermal conduction plays a crucial role in maintaining high temperatures at the core, while radiative cooling is prominent in the outer plasma regions, contributing to the cooling and dimming effects. The study also highlights the importance of magnetic flux tubes in shaping these plasma structures, with the symmetry of the density and temperature profiles supporting the confinement of these structures. These findings contribute to a better understanding of the physical processes governing plasma behavior in astrophysical contexts such as solar flares, stellar atmospheres, and galaxy clusters. Additionally, our results emphasize the need for further multi-dimensional simulations and empirical observations to validate and expand upon these findings, ultimately providing insights into space weather phenomena and other plasma-related processes in the universe. The study's findings have potential implications for space weather forecasting, stellar physics, and plasma dynamics in various astrophysical systems.

Abstract

Planetary alignments have intrigued astronomers, cultural historians, and religious scholars for centuries as a point of intersection between science and human belief systems. These celestial events have historically been associated with harmony, transformation, and symbolism, with varying interpretations across civilizations. This study modeled planetary alignments involving the Sun, Mercury, Venus, Earth, and Mars from 2000 to 2100. The analysis employed elliptical orbital mechanics to predict the timing and frequency of these events, focusing on angular separations and gravitational interplay among the celestial bodies. The findings showed more frequent alignments between Earth and Mars in 2025, 2051, 2076, and 2100. However, a simultaneous alignment involving all five planets—Sun, Mercury, Venus, Earth, and Mars—was rare, occurring only once in 2025. This singular event highlights the intricate dynamics of orbital mechanics and gravitational forces that govern planetary motion. The alignments were discovered to have significant cultural and spiritual, representing themes of peace and rebirth in many different traditions. The study underscores the importance of interdisciplinary collaboration to explore the multifaceted significance of celestial events, bridging the realms of astronomy, cultural studies, and spirituality. The rare 2025 alignment offers a unique opportunity for public engagement in astronomy, fostering a deeper appreciation of the cosmos. Moreover, preserving and integrating cultural interpretations of planetary alignments can promote a holistic understanding of their significance.

Abstract

This study investigates the intersection of biblical interpretations, philosophical thought, and gender theory to explore how the concept of human identity and gender roles has evolved. The purpose of this research is to analyze traditional religious and philosophical views on gender duality, focusing on interpretations of the Genesis creation narrative and philosophical ideas like Plato’s Symposium. Methodologically, the study adopts a qualitative approach, incorporating theological, historical, and logical analysis to assess various interpretations of gender identity. The findings reveal that while traditional religious perspectives emphasize gender complementarity, philosophical discourses present androgyny as a model for understanding human identity. This research highlights the need for a contemporary dialogue between theological institutions and modern gender theory to address issues of gender equality and identity formation. The conclusion recommends that religious institutions reconsider their stances on gender roles and engage with evolving social perspectives to promote a more inclusive view of human identity. Ultimately, the study advocates for inclusive theological reflection that respects traditional values and modern understandings of gender equality.

Abstract

The openness or closeness of the universe has long been a topic of discussion in both scientific and religious circles. Scientific theories in cosmology and quantum mechanics suggest an evolving and possibly infinite universe, while religious perspectives offer varied interpretations, often emphasizing divine purpose, interconnectedness, and ultimate destiny. Understanding this debate is crucial in addressing global challenges and fostering a more unified perspective on existence. Purpose: This study aims to explore the implications of an open or closed universe through scientific and religious perspectives, identifying areas of convergence and divergence. It examines how these views shape human consciousness, governance, and ethical responsibility toward planetary and interstellar sustainability. A qualitative comparative analysis was conducted using literature reviews of scientific theories, theological texts, and historical perspectives. Key scientific frameworks included thermodynamics, quantum mechanics, and astrophysics, while religious interpretations were drawn from Christianity, Islam, and other spiritual traditions. Findings: The analysis revealed that an open-system perspective aligns with both scientific discoveries—such as cosmic expansion and interstellar material exchange—and religious teachings that emphasize universal interconnectedness. A closed-system perspective, while useful in deterministic models, may limit broader explorations of human potential, intergalactic cooperation, and ethical governance. Conclusions: By fusing scientific discoveries with spiritual consciousness, an open-system paradigm promotes a transition from conflict-driven government to collaborative global and interplanetary stewardship. Recommendations: Policymakers, educators, and religious leaders should foster interdisciplinary dialogue, promote ethical space exploration, and develop frameworks for sustainable planetary and cosmic engagement.
