Determination of the Angular Momentum of Radiated Gravitons, Scalars, and Dark Photons from Binary Orbits
Arpan Hait, Subhendra Mohanty
We compute the energy and angular momentum radiated by compact binaries through gravitational waves, scalar and vector fields, using the field-theoretic approach. We observe that e…
A White Paper on The Multi-Messenger Science Landscape in India
Samsuzzaman Afroz, Sanjib Kumar Agarwalla, Dipankar Bhattacharya +35
The multi-messenger science using different observational windows to the Universe such as Gravitational Waves (GWs), Electromagnetic Waves (EMs), Cosmic Rays (CRs), and Neutrinos o…
Dark matter cooling during early matter-domination boosts sub-earth halos
Avik Banerjee, Debtosh Chowdhury, Arpan Hait +1
The existence of an early matter-dominated epoch prior to the Big Bang Nucleosynthesis may lead to a scenario where the thermal dark matter cools faster than plasma before the radi…
Ultra-light dark matter explanation of NANOGrav observations
Debtosh Chowdhury, Arpan Hait, Subhendra Mohanty +1
The angular correlation of pulsar residuals observed by NANOGrav and other pulsar timing array (PTA) collaborations show evidence in support of the Hellings-Downs correlation expec…
Gravitational memory signal from neutrino self-interactions in supernova
Soumya Bhattacharya, Debanjan Bose, Indranil Chakraborty +2
Neutrinos with large self-interactions, arising from exchange of light scalars or vectors with mass , can play a useful role in cosmology for structure forma…
Thermalization in the presence of a time-dependent dissipation and its impact on dark matter production
Debtosh Chowdhury, Arpan Hait
In standard cosmological scenarios, a heavy meta-stable field dominates the energy density of the universe after inflation. The dissipation of this field continuously sources high-…
Frequency space derivation of linear and non-linear memory gravitational wave signals from eccentric binary orbits
Arpan Hait, Subhendra Mohanty, Suraj Prakash
The memory effect in gravitational wave (GW) signals is the phenomenon, wherein the relative position of two inertial GW detectors undergoes a permanent displacement owing to the p…
