Quantum-Corrected Entropy Bounds on Black Hole Merger Efficiency
Jiswin Varghese
We examine the entropy balance of black hole mergers in the presence of quantum gravity corrections described by the Generalized Uncertainty Principle (GUP). Focusing on the coales…
Ultraluminous X-ray sources in the group-centric elliptical galaxy NGC 5813
T. R. Rajalakshmi, Somak Raychaudhury, Indulekha Kavila +1
The number of Ultraluminous X-ray Sources (ULXs) is observed to be correlated with the current star formation rate in late-type galaxies and with the stellar mass in early-type gal…
Star formation in interacting galaxy systems: UVIT imaging of NGC 7252 and NGC 5291
Geethika Santhosh, Rakhi R, Koshy George +2
Interactions play a significant role in the formation and evolution of galaxies in the Universe. The galaxy systems, NGC 7252 and NGC 5291 are two nearby interacting systems that a…
Primordial blackhole formation: Exploring chaotic potential with a sharp step via the GLMS perspective
Rinsy Thomas, Jobil Thomas, Minu Joy
A sharp step on a chaotic potential can enhance primordial curvature fluctuations on smaller scales to the to form primordial black holes (PBHs). The present…
Quantum SI: The New System of Units
Indulekha Kavila
This article gives an overview of the new SI and a few details as to how its setting up was achieved. Those interested in the story of how the kilogram was fixed by tying it to the…
Role of interactions in non-equilibrium transformations
Maria Rose, Sreekanth K Manikandan
For arbitrary non-equilibrium transformations in complex systems, we show that the distance between the current state and a target state can be decomposed into two terms: one corre…
