A quantitative explanation of the radio--X-ray correlation in black-hole X-ray binaries
Nikolaos D. Kylafis, Pablo Reig, Alexandros Tsouros
The observed correlation between the radio and X-ray fluxes in the hard state of black-hole X-ray binaries (BHXRBs) has been around for more than two decades. It is currently accep…
The RoboPol sample of optical polarimetric standards
D. Blinov, S. Maharana, F. Bouzelou +34
Optical polarimeters are typically calibrated using measurements of stars with known and stable polarization parameters. However, there is a lack of such stars available across the…
Long-term optical variability of the Be/X-ray binary GRO J2058+42
P. Reig, A. Tzouvanou, D. Blinov +1
We investigate the long-term optical variability of the Be/X-ray binary GRO J2058+42 and the possible connection with periods of enhanced X-ray activity. We performed an optical sp…
High energy Millihertz quasi-periodic oscillations in 1A 0535+262 with Insight-HXMT challenge current models
Ruican Ma, Lian Tao, Shuang-Nan Zhang +21
We studied the millihertz quasi-periodic oscillation (mHz QPO) in the 2020 outburst of the Be/X-ray binary 1A 0535+262 using Insight-HXMT data over a broad energy band. The mHz QPO…
Fast time optical variability in Be/X-ray binaries. Pulsation and rotation
P. Reig, J. Fabregat
Classical Be stars, regardless of spectral subtype, display multiperiodic light modulations in the frequency range 0.1-12 d, when observed with high-cadence and long duratio…
Multiwavelength observations of Swift J0243.6+6124 from 2017 to 2022
Wei Liu, Jingzhi Yan, Pablo Reig +8
We have obtained optical spectroscopy and photometry data during four years after the event. The long-term photometric light-curve and the equivalent widths of the Halpha and He I…
