Deep VLBI constraints on compact radio cores in four ultraluminous X-ray sources
Ailing Wang, Hua Feng, Tao An +7
We present high-sensitivity Very Long Baseline Interferometry (VLBI) observations of four ultraluminous X-ray sources (ULXs): Holmberg II X-1, IC 342 X-1, NGC 6946 X-1, and NGC 925…
4U 1556-60 as a very faint neutron star X-ray binary at 700 pc with an undetected radio jet
Eliot C. Pattie, Thomas J. Maccarone, Thomas Russell +3
4U 1556-60 is a low-mass X-ray binary that was discovered more than 50 years ago as a persistent X-ray source; however, very little was known about it. Recently, Gaia obtained a pa…
Detection of low-luminosity X-ray pulsations from the accreting millisecond pulsar IGR J17511-3057: An ever-thinning thread between bright accretion and sub-luminous states
Giulia Illiano, Alessandro Papitto, Sergio Campana +14
After nearly a decade in quiescence, the accreting millisecond pulsar IGR J175113057 displayed a new outburst on 2025 February 11, its third since discovery, following previous…
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…
Low-frequency spectra of neutron star + OB supergiant binaries: Does wind density drive persistent and flaring modes of accretion?
J. van den Eijnden, L. Sidoli, M. DÃaz Trigo +10
Neutron star high-mass X-ray binaries are well-studied in wavebands between the infrared and hard X-rays. Their low-frequency millimeter and radio properties, on the other hand, re…
Infrared Synchrotron Emission in the Soft State of GX 339-4 and the Mid-Infrared/X-ray Luminosity Plane of Black Hole X-ray Binaries
P. Gandhi, D. M. Russell, M. C. Baglio +33
Progress in understanding the growth of accreting black holes remains hampered by a lack of sensitive coordinated multiwavelength observations. In particular, the mid-infrared (MIR…
