X-ray observations of the very-faint X-ray transient XMMSL1 J171900.4--353217: A new candidate neutron star low-mass X-ray binary

O. Ahmed, N. Degenaar, R. Wijnands +1

XMMSL1 J171900.4-353217 is a very-faint X-ray transient that was discovered in 2010 March when it exhibited an outburst. We report on 7 observations, obtained with the X-Ray Telesc…

Evidence for inflows and outflows in the nearby black hole transient Swift J1727.8-162

D. Mata Sánchez, T. Muñoz-Darias, M. Armas Padilla +2

We present 20 epochs of optical spectroscopy obtained with the GTC-10.4m telescope across the bright discovery outburst of the black hole candidate Swift J1727.8-162. The spectra c…

Evidence for a black hole in the historical X-ray transient A 1524-61 (=KY TrA)

I. V. Yanes-Rizo, M. A. P. Torres, J. Casares +5

We present VLT spectroscopy, high-resolution imaging and time-resolved photometry of KY TrA, the optical counterpart to the X-ray binary A 1524-61. We perform a refined astrometry…

The omnipresent flux-dependent optical dips of the black hole transient Swift J1357.2-0933

G. Panizo-Espinar, T. Muñoz-Darias, M. Armas Padilla +15

Swift J1357.2-0933 is a black hole transient of particular interest due to the optical, recurrent dips found during its first two outbursts (in 2011 and 2017), with no obvious X-ra…

An infrared FWHM- correlation to uncover highly reddened quiescent black holes

V. A. Cúneo, J. Casares, M. Armas Padilla +7

Among the sample of Galactic transient X-ray binaries (SXTs) discovered to date, about 70 have been proposed as likely candidates to host a black hole. Yet, only 19 have been dynam…

H spectroscopy of the high-inclination black hole transient Swift J1357.2-0933 during quiescence

A. Anitra, D. Mata Sanchez, T. Munoz-Darias +6

Swift J1357.2-0933 is a transient low-mass X-ray binary hosting a stellar-mass black hole. The source exhibits optical dips and very broad emission lines during both outburst and q…
