Simulating megaparsec-scale jets of radio galaxies: Magneto-hydrodynamics of jets reaching 5 Mpc
Gourab Giri, Dario Borgogno, Marco Tavani +9
Extragalactic jets have long prompted the question of how far relativistic outflows can extend, with some radio sources reaching 5 - 7 Mpc in length. These great extents motivate i…
TeV spectral bump of cosmic-ray protons and helium nuclei: the role of nearby supernova remnants
Sourav Bhadra, Satyendra Thoudam, Biman B Nath +1
The existence of nearby discrete cosmic-ray sources can lead to many interesting effects on the observed properties of cosmic rays. Recent measurements of cosmic rays with the CALE…
Microphysics of Circumgalactic Turbulence Probed by Fast Radio Bursts and Quasars
S. K. Ocker, M. Chen, S. P. Oh +1
The circumgalactic medium (CGM) is poorly constrained at the sub-parsec scales relevant to turbulent energy dissipation and regulation of multi-phase structure. Fast radio bursts (…
Breaking into the window of primordial black hole dark matter with x-ray microlensing
Manish Tamta, Nirmal Raj, Prateek Sharma
Primordial black holes (PBHs) in the mass range may constitute all the dark matter. We show that gravitational microlensing of bright x-ray pulsars prov…
