Stars Crushed by Black Holes. III. Mild Compression of Radiative Stars by Supermassive Black Holes
Suman Kumar Kundu, Eric R. Coughlin, C. J. Nixon
A tidal disruption event (TDE) occurs when the gravitational field of a supermassive black hole (SMBH) destroys a star. For TDEs in which the star enters deep within the tidal radi…
Spherically Symmetric Accretion onto a Compact Object through a Standing Shock: The Effects of General Relativity in the Schwarzschild Geometry
Suman Kumar Kundu, Eric R. Coughlin
A core-collapse supernova is generated by the passage of a shockwave through the envelope of a massive star, where the shock wave is initially launched from the ``bounce'' of the n…
Does the Vacuum Gravitate on Microscopic Scales? Rydberg Atoms Indicate Probably Not
Suman Kumar Kundu, Arnab Pradhan, Carl Rosenzweig
The cosmological constant presents one of the most fascinating and confounding problems in physics. A straightforward, seemingly robust prediction of quantum mechanics and general…
A CFT interpretation of cosmological correlation functions in vacua in de-Sitter space
Sachin Jain, Nilay Kundu, Suman Kundu +2
de-Sitter(dS) space allows for a generalized class of vacua, known as vacua, described by some parameters. The Bunch-Davies (BD) vacua is a point in this parameter space. The c…
