Exploring the effects of dark matter - dark energy interaction on cosmic evolution in viscous dark energy scenario
Ashadul Halder, Madhurima Pandey, Rupa Basu +1
We explore the influence of interactions between dark matter (DM) and dark energy (DE) on the cosmic evolution of the Universe within a viscous dark energy (VDE) framework. Moving…
Constraining the parameters of an isolated neutron star using the lensed HI signal at uGMRT
Rupa Basu, Siddhartha Bhattacharyya, Anjan Kumar Sarkar +2
The strength of the HI signal originating from a distant galaxy at a cosmological distance is several orders of magnitude lower than the foreground and background noise and hence i…
Addressing the self-interaction for ELDER dark matter from the 21-cm signal
Rupa Basu, Debasish Majumdar, Ashadul Halder +1
The self-interacting dark matter can affect various cosmological processes. Such interactions can be number conserving (\emph{e.g.} ) or number violating (\emph{e.…
Exploring multimessenger signals from heavy dark matter decay with EDGES 21-cm result and IceCube
Ashadul Halder, Madhurima Pandey, Debasish Majumdar +1
The primordial heavy or superheavy dark matter that could be created during the reheating or preheating stage of the Universe can undergo QCD cascade decay process to produce lepto…
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…
