A Real-Time Jet Laboratory in Swift J1727.8-1613
Callan M. Wood, James C. A. Miller-Jones, Arash Bahramian +16
We present the results of our intensive VLBI campaign on the black-hole low-mass X-ray binary (LMXB) Swift J1727.8-1613 during its 2023-2024 outburst. We observed the repeated quen…
From compact jets to extended lobes: radio morphologies of distant quasars at z > 4
K. Ã. Gabányi, M. Kunert-Bajraszewska, A. Krauze +9
High-redshift quasars play an essential role in studying the growth and evolution of supermassive black holes and active galactic nuclei (AGN). Radio-loud quasars additionally enab…
SKAVLBI view of AGN jets in the early Universe
C. Spingola, M. Mezcua, Y. Liu +33
Active Galactic Nuclei (AGN) are among the brightest sources in the Universe, and those that are also jetted are uniquely valuable at the earliest epochs, because their relativisti…
An Ejection Event Captured by VLBI During the Outburst of Swift J1727.81613
Hongmin Cao, Jun Yang, Sándor Frey +9
We observed a newly-discovered Galactic black hole X-ray binary Swift J1727.81613 with the European Very Long Baseline Interferometry Network (EVN) at 5 GHz. The observation was…
Tracking the jet-like corona of black hole Swift J1727.8-1613 during a flare state through Type-C quasi-periodic oscillations
Jie Liao, Ning Chang, Lang Cui +10
Type-C quasi-periodic oscillations (QPOs) in black hole X-ray transients typically manifest in the low-hard and hard-intermediate states. This study presents a detailed spectral an…
Proper Motion and Natal Kick in the Galactic Black Hole X-ray Binary AT2019wey
Lang Cui, Pengfei Jiang, Tao An +9
Understanding the formation mechanisms of stellar-mass black holes in X-ray binaries (BHXBs) remains a fundamental challenge in astrophysics. The natal kick velocities imparted dur…
