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…
A study of natural frequencies in a dynamic corona-disk system
A. Mastichiadis, M. Petropoulou, N. D. Kylafis
Black-hole X-ray binaries (BHXRBs) in the hard and hard-intermediate spectral (and temporal) states exhibit in their power spectra characteristic frequencies called type-C quasi-pe…
Cyclotron line formation by reflection on the surface of a magnetic neutron star
N. D. Kylafis, J. E. Trümper, N. A. Loudas
Accretion onto magnetic neutron stars results in X-ray spectra that often exhibit a cyclotron resonance scattering feature (CRSF) and, sometimes, higher harmonics of it. Two places…
The Time-Dependent Distribution of Optical Polarization Angle Changes in Blazars
S. Kiehlmann, D. Blinov, I. Liodakis +17
At optical wavelengths, blazar Electric Vector Position Angle (EVPA) rotations linked with gamma-ray activity have been the subject of intense interest and systematic investigation…
Inclination Dependence of The Time-Lag -- Photon-Index Correlation in BHXRBs and its Explanation with a Simple Jet Model
N. Kylafis, P. Reig
Recently, we reported an observational correlation between a) the time-lag of the hard (9 - 15 keV) with respect to the soft (2 - 5 keV) X-ray photons in black-hole X-ray binaries…
Inclination effects on the X-ray emission of Galactic black-hole binaries
P. Reig, N. Kylafis
Galactic black-hole X-ray binaries (BHBs) emit a compact, optically thick, mildly relativistic radio jet when they are in the hard and hard-intermediate states. In these states, BH…
