Heating of the intracluster medium by buoyant bubbles and sound waves
Asif Iqbal, Subhabrata Majumdar, Biman B. Nath +1
Active galactic nuclei (AGN) powered by the central Super-Massive Black Holes (SMBHs) play a major role in modifying the thermal properties of the intracluster medium (ICM). In thi…
Density perturbation and cosmological evolution in the presence of magnetic field in gravity models
Samarjit Chakraborty, Sarbari Guha
In this paper, we have investigated the density perturbations and cosmological evolution in the FLRW universe in presence of a cosmic magnetic field, which may be assumed to mimic…
Dynamical conditions and causal transport of dissipative spherical collapse in gravity
Sarbari Guha, Uttaran Ghosh
In this paper, we have investigated the non-adiabatic spherical gravitational collapse in the framework of the theory of gravity with a locally anisotropic fluid that unde…
Bounds on Dark Matter Annihilation Cross-sections from Inert Doublet Model in the context of 21 cm Cosmology of Dark Ages
Rupa Basu, Madhurima Pandey, Debasish Majumdar +1
We study the fluctuations in the brightness temperature of 21-cm signal at the dark ages () with a dark matter candidate in Inter Doublet Model (IDM). We then e…
