An active galactic nucleus (AGN) is powered by the matter accreting onto the central supermassive black hole (SMBH) at the centre of a galaxy. Changing look (CL) AGNs are those sources that show rapid change in the column density of...
Forecasting the strength of the solar cycle is of the utmost importance because it affects space weather and our technology-based society. By a riveting feature of the solar cycles, i.e. Waldmeier effect (WE2), we find a linear relationship between the...
The article discusses the structure of the neutron star crust. In the neutron star’s crust, exotic structures commonly known as “nuclear pasta” are believed to exist. The pasta structure impacts various structural, thermal and transport properties of the crust and...
The interstellar molecular clouds are the high-density regions between the stars having elements in the molecular phase. These clouds usually come up with different structures based on the influence of nearby massive ionizing stars. Also, these stars can either hinder...
General theory of relativity proposed by Albert Einstein in 1915 has passed all the experimental and observational tests with flying colors. Gravitational waves from the merger of compact binaries such as black holes and neutron stars provide a unique opportunity...
Hydrodynamic flows around black holes is a fascinating area of research that provides a window into the processes that power relativistic jets and energetic particle acceleration. However, this is a challenging task when studied using the full general relativistic framework....
