Probing black-hole accretion through time variability
Barbara De Marco, Sara E. Motta, Tomaso M. Belloni
Flux variability is a remarkable property of black hole (BH) accreting systems, and a powerful tool to investigate the multi-scale structure of the accretion flow. The X-ray band i…
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…
Black hole mass and spin measurements through the Relativistic Precession Model: XTE J1859+226
S. E Motta, T. Belloni, L. Stella +5
The X-ray light curves of accreting black holes and neutron stars in binary systems show various types of quasi-periodic oscillations (QPOs), the origin of which is still debated.…
Radio observations of the Black Hole X-ray Binary EXO 1846-031 re-awakening from a 34-year slumber
D. R. A. Williams, S. E. Motta, R. Fender +15
We present radio [1.3 GHz MeerKAT, 4-8 GHz Karl G. Jansky Very Large Array (VLA) and 15.5 GHz Arcminute Microkelvin Imager Large Array (AMI-LA)] and X-ray (Swift and MAXI) data fro…
Comprehensive coverage of particle acceleration and kinetic feedback from the stellar mass black hole V404 Cygni
R. P. Fender, K. P. Mooley, S. E. Motta +8
We present analysis of comprehensive radio observations of the black hole V404 Cyg during its 2015 outburst. These data represent the best ever coverage of jet production and parti…
Discovery of a radio emitting neutron star with an ultra-long spin period of 76 seconds
Manisha Caleb, Ian Heywood, Kaustubh Rajwade +19
The radio-emitting neutron star population encompasses objects with spin periods ranging from milliseconds to tens of seconds. As they age and spin more slowly, their radio emissio…
