Viscous Dark Energy and Mass-Varying Dark Matter in Lyra Manifold: Cosmological Dynamics and Observational Constraints
Giridhari Deogharia, Madhurima Pandey, Ashadul Halder
We investigate the cosmological dynamics of a universe described by Lyra's geometry in the presence of dark energy (DE) and dark matter (DM). Dark energy is modeled as a quintessen…
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…
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…
Probing the effects of primordial black holes on 21-cm EDGES signal along with interacting dark energy and dark matter - baryon scattering
Ashadul Halder, Madhurima Pandey
21-cm radio signal has emerged as an important probe in investigating the dark age of the Universe (recombination to reionization). In the current analysis, we explore the combined…
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…
Addressing -ray emissions from dark matter annihilations in 45 milky way satellite galaxies and in extragalactic sources with particle dark matter models
Ashadul Halder, Shibaji Banerjee, Madhurima Pandey +1
The mass to luminosity ratio of the dwarf satellite galaxies in the Milky Way suggests that these dwarf galaxies may contain substantial dark matter. The dark matter at the dense r…
