AstronEra is the world’s first Astronomy dedicated elearning platform. I, Shweta Kulkarni, FRAS, Founder of AstronEra, have been working for the popularisation of Astronomy since the age of 16. AstronEra has developed innovative methods for…

Host galaxies of high redshift quasars (QSOs) are of interest. They provide us with a valuable opportunity to investigate the physics relevant to the starburst-active galactic nuclei (AGN), the energetic compact region at the center of a galaxy,…

Short-duration gamma-ray bursts (sGRBs) are brief (duration < 2 sec) flashes of gamma-rays produced by binary neutron star (BNS) or possibly neutron star black hole (NSBH) mergers.
The first joint detection of a gravitational wave…

Due to the absence of a continuous upstream solar wind monitor at Mars, little is known about the variability of the interplanetary magnetic field as it reaches the planet. As such it is often assumed that the IMF is slow changing, although it is…

The evolution of two giant stars in a binary (a two-star system) can lead to the formation of some of the most violently interacting objects in the universe, such as a combination of neutron star and black hole pairs. The joint orbit of these…

Virtually all large galaxies, like the Milky Way, host black holes at their centres. Some of these black holes are ‘active’, i.e. they are growing by devouring gas, releasing massive amounts of energy as the gas spirals inwards. Recent…

Blazars are a sub-category of radio-loud Active Galactic Nuclei having their jet pointing towards us and are known for their emission covering practically all frequencies of the electromagnetic spectrum. These sources, in some cases, exhibit a…

Recent observations of Molecular Clouds suggests that ambient environment, i.e., the magnitude of external pressure, affects their evolution. We explored this hypothesis numerically by developing 3-d hydrodynamic realizations of a cloud for…

In recent studies, there have been several reports of a detection of an unexplained X-ray emission at 3.5 keV in various astrophysical systems. One interpretation of this excess is from the decay of sterile neutrino dark matter. The most…

Analyzing nearby and distant Supernovae Type Ia data, Riess et al. [1] and Perlmutter et al. [2] discovered the universe's late-time accelerated expansion.(Noble Prize in Physics, 2011) Once abandoned by Einstein, the cosmological constant…
