AGN X-ray coronae at high luminosity: A broadband study of RBS 229 and PG 1407+265

Alessandro Leonardo Lai, Stefano Bianchi, Andrea Marinucci +8

Context. The X-ray emission of active galactic nuclei (AGNs) is commonly interpreted as arising from Comptonisation in a hot corona above the accretion disc. A prominent soft X-ray…

A Broadband X-ray Analysis and Optical Counterpart Search of IC5052 ULX

Nabil Brice, Dominic J. Walton, Felix Fürst +10

We present broadband X-ray spectral and timing analysis of the Ultra-luminous X-ray source (ULX) in IC5052 using simultaneous XMM-Newton and NuSTAR observations from 2022, suppleme…

An energetic dirty fireball detected in soft X-rays

C. -Y. Dai, J. Quirola-Vásquez, Y. -H. Wang +76

The collapse of massive stars drives explosions that power relativistic fireballs. If only a small amount of matter is entrained, such clean fireballs can expand with Lorentz facto…

PACHA: Probing AGN Coronae with High-redshift AGN

Xiurui Zhao, Elias Kammoun, Marco Ajello +18

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…

A comprehensive search for high-velocity X-ray sources: New compact object binary candidates in the Gaia era

Yue Zhao, Poshak Gandhi, Christian Knigge +6

We perform a comprehensive search for high-velocity X-ray sources with large X-ray/optical flux ratios (), identifying candidates for interacting black h…
