We use very long baseline interferometry to measure the proper motions of three black hole
X-ray binaries (BHXBs). Using these results together with data from the literature and Gaia …

Black hole low-mass X-ray binaries (BH LMXBs) evolve in a similar way during outburst.
Based on the X-ray spectrum and variability, this evolution can be divided into three …

ABSTRACT The International Gamma-Ray Astrophysics Laboratory (INTEGRAL), launched
in 2002, continues its successful work in observing the sky at energies E> 20 keV. The …

The continuum-fitting and the iron-line methods are currently the two leading techniques for
measuring the spins of accreting black holes. In the past few years, these two methods have …

We present evidence for a 0.278 (8) d (= 6.7 h) orbital period in the X-ray transient GRS
1716-249 (= N Oph 93), based on a superhump modulation detected during the 1995 mini …

During the outbursts of black hole X-ray binaries (BHXRBs), their accretion flows transition
through several states. The source luminosity rises in the hard state, dominated by …

ABSTRACT X-ray signatures of outflowing gas have been detected in several accreting
black hole binaries, always in the soft state. A key question raised by these observations is …

A Multiwavelength Study of GRS 1716-249 in Outburst: Constraints on Its System

Context. X-ray binaries in outburst typically show two canonical X-ray spectral states (ie,
hard and soft states), as well as different intermediate states, in which the physical properties …

We present optical spectroscopy obtained with the GTC, VLT, and SALT telescopes during
the decline of the 2016–2017 outburst of the black hole candidate GRS 1716− 249 (Nova …
