Accreting stellar-mass black holes
Greg Marcel, Bailey Tetarenko, Adam Ingram +3
Accreting stellar-mass black holes exhibit dramatic variability across the electromagnetic spectrum, including spectral state transitions, outbursts, and jet production, making the…
Accretion geometry and spectral evolution in 1A 1118-61: a comparison of the 2009 and 2026 outbursts
Kinjal Roy, Aru Beri, Rahul Sharma +1
We present a detailed spectro-temporal study of the Be X-ray binary pulsar during its brightest recorded outburst in 2026, using \textit{Swift} and \textit{NuSTAR} o…
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…
Characterisation of H spectra from EXO 051910+3737.7 X-rays binaries
Pornisara Nuchvanichakul, Puji Irawati, Pakakaew Rittipruk +4
We investigate the spectral characteristics of the Be/X-ray binary system, EXO 051910+3737.7, in which Be/X-ray systems are the largest sub-class of high-mass X-ray binaries. Spect…
