PACHA: Probing AGN Coronae with High-redshift AGN
Xiurui Zhao, Elias Kammoun, Marco Ajello +19
The X-ray emission of active galactic nuclei (AGN) is generally attributed to inverse Compton scattering of accretion-disk photons by hot electrons in a compact corona. In local AG…
Establishing a Connection Between the Jet and the Corona in Black Hole Low Mass X-Ray Binaries
Eric Davidson, Jaiverdhan Chauhan, Anne Lohfink +3
Low-mass black hole X-ray Binaries (LMXBs) undergo outbursts, during which their brightness increases greatly for timescales of months. The X-ray accretion and radio jet properties…
Chandra and HST Observations of Radio-Selected (Wandering) Massive Black Hole Candidates in Dwarf Galaxies
Megan R. Sturm, Amy E. Reines, Anne M. Lohfink +6
We present Chandra X-ray Observatory and Hubble Space Telescope (HST) follow-up observations of 12 dwarf galaxies from Reines et al. (2020) that are potential hosts of radio-select…
QPO signatures of disk restoration after type-I X-ray bursts from 4U~1636536
Suchismito Chattopadhyay, Jaiverdhan Chauhan, Ranjeev Misra +4
Type--I thermonuclear bursts (TNBs) from neutron star low-mass X-ray binaries (NS LMXBs) originate on the neutron star's surface from the unstable burning of the accreted material.…
A new independent look at the galactic black hole low-mass X-ray binary distribution
Youssef Abdulghani, Anne M Lohfink, Jaiverdhan Chauhan
Investigations of the Galactic black hole low-mass X-ray binaries (BH-LMXBs) offer valuable insights into the elusive black hole population in the Milky Way. Motivated by recent te…
Probing thermonuclear bursts and X-ray reflection features in Aql X-1 during 2024 outburst
Manoj Mandal, Sabyasachi Pal, G. K. Jaisawal +3
We report the broadband timing and spectral properties of the neutron star low-mass X-ray binary Aql X-1 during the 2024 outburst with NICER, NuSTAR, and Swift observatories. We de…
