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…
Peering through the dip: IXPE unveils the extended scattering environment of GX 13+1
Alessandro Di Marco, Fabio La Monaca, Luigi Stella +17
Neutron star low-mass X-ray binaries feature complex accretion geometries, often including an accretion disk corona or disk winds. Here, a study of the highly inclined dipping sour…
A cooler look at the environment of Cygnus X-1: Searching for dynamical interactions within cold molecular gas
Pau Bosch-Cabot, Alexandra J. Tetarenko, Valentà Bosch-Ramon +7
We present IRAM--30m observations aimed at identifying potential outflow-interstellar medium interaction sites in the vicinity of the black hole X-ray binary Cygnus X--1, which dis…
A semi-coherent search for optical pulsations from Scorpius X-1
Riccardo La Placa, Alessandro Papitto, Giulia Illiano +14
The emission of continuous gravitational waves (CWs) possibly explains why pulsars spinning with a period shorter than a millisecond have not been observed so far. Neutron stars ac…
A multiwavelength study of the Galactic center black hole candidate MAXI J1744-294
Shifra Mandel, Kaya Mori, Paul A. Draghis +37
For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…
Detection of an Extremely Luminous Radio Counterpart to the Be/X-ray Binary A0538-66
Justine Crook-Mansour, Rob Fender, Alex Andersson +14
We present the discovery of radio emission from the Be/X-ray binary A0538-66 with the Australian Square Kilometre Array Pathfinder (ASKAP), and results from a subsequent weekly mon…
