Optical observations of candidate host galaxies of eight fast X-ray transients
Agnes P. C. van Hoof, Peter G. Jonker, Lieke Tommel +15
Fast X-ray transients (FXTs) are extragalactic flashes of X-rays with a typical duration of minutes to hours for which a variety of origins has been proposed and observed. To decip…
Revisiting the fundamental parameters for the black hole X-ray transient Swift J1753.5-0127
I. V. Yanes-Rizo, M. A. P. Torres, J. Casares +4
We present time-resolved Gran Telescopio Canarias optical spectroscopy and William Herschel Telescope -band photometry of the X-ray transient SWIFT J1753.5-0127 in quiescence. T…
When the disc's away, the stars will play: dynamical masses in the nova-like variable KR Aur with a pinch of accretion
P. Rodríguez-Gil, T. Shahbaz, M. A. P. Torres +8
We obtained time-resolved optical photometry and spectroscopy of the nova-like variable KR Aurigae in the low state. The spectrum reveals a DAB white dwarf and a mid-M dwarf compan…
Quiescent NIR and optical counterparts to candidate black hole X-ray binaries
K. M. López, P. G. Jonker, M. A. P. Torres +3
We present near-infrared and optical imaging of fifteen candidate black hole X-ray binaries. In addition to quiescent observations for all sources, we also observed two of these so…
Characterisation of a candidate dual AGN
D. Lena, G. Panizo-Espinar, P. G. Jonker +2
We present Chandra and optical observations of a candidate dual AGN discovered serendipitously while searching for recoiling black holes via a cross-correlation between the serendi…
The mass function of GX 339-4 from spectroscopic observations of its donor star
M. Heida, P. G. Jonker, M. A. P. Torres +1
We obtained 16 VLT/X-shooter observations of GX 339-4 in quiescence in the period May - September 2016 and detected absorption lines from the donor star in its NIR spectrum. This a…
