Transmutation Timescales for Dark Matter Induced Collapse of Compact Stars into Black Holes
H. A. Adarsha, Chandrachur Chakraborty, Sudip Bhattacharyya
Ultra-heavy asymmetric dark matter (DM) particles captured by compact stars can thermalize, self-gravitate, and collapse to form an endoparasitic black hole (EBH), whose subsequent…
Authentication over Arbitrarily Varying Channels with Causal Adversaries
Mayank Bakshi, Vinod M. Prabhakaran, Bikash Kumar Dey +1
We study authentication over a discrete memoryless arbitrarily varying channel (AVC) in which the adversary selects the channel state causally based on past channel outputs. We pro…
Filaments within filaments: unraveling the hierarchy of the cosmic web
Saee Dhawalikar, Aseem Paranjape, Shadab Alam
Cosmic filaments are the most striking feature of the hierarchical cosmic web. Yet, their own sub-structure remains unexplored, unlike the well-known, universal halo/sub-halo hiera…
Tilted thin accretion disks in the full Kerr spacetime and their implications
K. S. Sruthy, Chandrachur Chakraborty, Sudip Bhattacharyya
We derive a steady-state warped-disk equation in the full Kerr spacetime to study the tilt dynamics of a thin, viscous accretion disk around a spinning collapsed object. The formul…
A Quiet Host in an Active Planet-Forming Disk: Optical Spectroscopy of WISPIT 2
C. Swastik, M. Bestha, L. S. Sonith +11
WISPIT 2 is a young pre-main-sequence star hosting a multi-ringed transition disk and two directly imaged protoplanets, including the accreting WISPIT 2b, making it the closest kno…
Enhancing the Cherenkov Telescope Array Observatory high-level performance through an event-type-based analysis
Juan Bernete, Silvia García-Soto, Tarek Hassan +4
The analysis traditionally employed by Imaging Atmospheric Cherenkov Telescopes involves optimizing quality cuts to select a sub-sample of high-quality events. These events are use…
