A refined dynamical mass for the black hole in the X-ray transient XTE J1859+226
I. V. Yanes Rizo, M. A. P. Torres, J. Casares +8
We present two contiguous nights of simultaneous time-resolved GTC spectroscopy and WHT photometry of the black hole X-ray transient XTE J1859+226, obtained in 2017 July during qui…
A persistent ultraviolet outflow from an accreting neutron star binary transient
N. Castro Segura, C. Knigge, K. S. Long +31
All disc-accreting astrophysical objects produce powerful outflows. In binaries containing neutron stars (NS) or black holes, accretion often takes place during violent outbursts.…
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…
Soft X-ray emission lines in the X-ray binary Swift J1858.6-0814 observed with XMM-Newton-RGS: disc atmosphere or wind?
D. J. K. Buisson, D. Altamirano, M. Díaz Trigo +11
We find soft X-ray emission lines from the X-ray binary Swift J1858.6-0814 in data from XMM-Newton-RGS: N VII, O VII and O VIII, as well as notable residuals short of a detection a…
Discovery of optical outflows and inflows in the black hole candidate GRS 1716-249
V. A. Cúneo, T. Muñoz-Darias, J. Sánchez-Sierras +12
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 Oph 1993)…
The variable radio counterpart of Swift J1858.6-0814
J. van den Eijnden, N. Degenaar, T. D. Russell +18
Swift J1858.6-0814 is a transient neutron star X-ray binary discovered in October 2018. Multi-wavelength follow-up observations across the electromagnetic spectrum revealed many in…
