Impact of the Infrared Cutoff on Structure Formation in Tsallis Holographic Dark Energy
Biswajit Das
We investigate the viability of Tsallis holographic dark energy (THDE) models, focusing on the role of the infrared (IR) cutoff in the growth of cosmic structures. Considering two…
Model-independent reconstruction of cosmic thermodynamics and dark energy dynamics
Afaq Maqsood, Tanima Duary
We perform a model-independent investigation of the thermodynamic evolution of the Universe by reconstructing the expansion history from observational data using Gaussian Process r…
Probing Interacting Dark Sectors with upcoming Post-Reionization and Galaxy Surveys
Rahul Shah, Antara Dey, Purba Mukherjee +1
We investigate the constraining power of future post-reionization and galaxy surveys on possible interactions between dynamical dark energy and dark matter. The analysis focuses on…
Thermal enhancement of inflationary magnetic fields
Arjun Berera, Suddhasattwa Brahma, Zizang Qiu +1
We investigate primordial magnetogenesis by assuming the gauge field is prepared in a thermal state during inflation rather than the standard Bunch-Davies vacuum. The temperature $…
Prospects of Indirect Detection of Dark Matter via Primordial Black Hole Induced Gravitational Waves
Debarun Paul, Md Riajul Haque, Supratik Pal
Primordial black holes (PBHs), produced in the early Universe, can source a stochastic background of induced gravitational waves (GWs) and provide a non-thermal origin for dark mat…
Exploring the Co-SIMP dark matter model using the 21-cm signal from the dark ages
Debarun Paul, Sourav Pal, Deepthi Moorkanat +3
The redshifted 21-cm signal from the dark ages offers a powerful probe of cosmological models and the underlying dark matter (DM) microphysics. We investigate deviations from the s…
