Disk-jet coupling changes as a possible indicator for outbursts from GX 339-4 remaining within the X-ray hard state

S. E. M. de Haas, T. D. Russell, N. Degenaar +8

We present quasi-simultaneous radio, (sub-)millimetre, and X-ray observations of the Galactic black hole X-ray binary GX 339-4, taken during its 2017--2018 outburst, where the sour…

Simultaneous NICER and NuSTAR Observations of the Ultra-compact X-ray Binary 4U 1543-624

R. M. Ludlam, A. D. Jaodand, J. A. García +8

We present the first joint NuSTAR and NICER observations of the ultra-compact X-ray binary (UCXB) 4U 1543624 obtained in 2020 April. The source was at a luminosity of $L_{0.5-50…

Rapid compact jet quenching in the Galactic black hole candidate X-ray binary MAXI J1535-571

T. D. Russell, M. Lucchini, A. J. Tetarenko +23

We present results from six epochs of quasi-simultaneous radio, (sub-)millimetre, infrared, optical, and X-ray observations of the black hole X-ray binary MAXI~J1535571. These o…

Optical spectroscopy of 4U 1812-12: an ultra-compact X-ray binary seen through an H II region

M. Armas Padilla, T. Muñoz-Darias, F. Jiménez-Ibarra +6

The persistent, low-luminosity neutron star X-ray binary 4U 1812-12 is a potential member of the scarce family of ultra-compact systems. We performed deep photometric and spectrosc…

The Swift Bulge Survey: Motivation, Strategy, and First X-ray Results

A. Bahramian, C. O. Heinke, J. A. Kennea +12

Very faint X-ray transients (VFXTs) are X-ray transients with peak X-ray luminosities () of erg/s, which are not well-understood. We carried out a survey…

Eclipses of jets and discs of X-ray binaries as a powerful tool for understanding jet physics and binary parameters

Thomas J. Maccarone, Jakob van den Eijnden, Thomas D. Russell +1

We calculate the expected effects on the spectral energy distributions and light curves in X-ray binary jets from eclipses by the donor stars. Jets will be eclipsed for all inclina…
