Component separation map-making for stochastic gravitational wave background
Abhishek Parida, Jishnu Suresh, Sanjit Mitra +1
Superposition of unresolved sources of gravitational waves (GW) is expected to create a persistent background of stochastic gravitational wave background (SGWB). Different types of…
Energy emission from high curvature region and its backreation
Takafumi Kokubu, Sanjay Jhingan, Tomohiro Harada
A strong gravity naked singular region can give important clues towards understanding classical as well as spontaneous nature of General Relativity. We propose here a model for ene…
Primordial black hole formation in the matter-dominated phase of the Universe
Tomohiro Harada, Chul-Moon Yoo, Kazunori Kohri +2
We investigate primordial black hole formation in the matter-dominated phase of the Universe, where nonspherical effects in gravitational collapse play a crucial role. This is in c…
Spherical and nonspherical models of primordial black hole formation: exact solutions
Tomohiro Harada, Sanjay Jhingan
We construct spacetimes which provide spherical and nonspherical models of black hole formation in the flat Friedmann--Lemaitre--Robertson--Walker (FLRW) universe with the Lemaitre…
Component Separation of a Isotropic Gravitational Wave Background
Abhishek Parida, Sanjit Mitra, Sanjay Jhingan
A Gravitational Wave Background (GWB) is expected in the universe from the superposition of a large number of unresolved astrophysical sources and phenomena in the early universe.…
XMM-Newton view of a hard X-ray transient IGR J17497-2821
Md. Shah Alam, Dipanjan Mukherjee, Aditya S. Mondal +3
We present spectral and energy dependent timing characteristics of the hard X-ray transient IGR J17497-2821 based on XMM-Newton observations performed five and nine days after its…
