AGILE, Fermi, Swift, and GASP-WEBT multi-wavelength observations of the high-redshift blazar 4C 71.07 in outburst
S. Vercellone, P. Romano, G. Piano +56
The flat-spectrum radio quasar 4C 71.07 is a high-redshift (), -loud blazar whose optical emission is dominated by the thermal radiation from accretion disc. 4C 7…
A Study of the High-Luminosity Quasar HS 1946+7658
B. Mihov, L. Slavcheva-Mihova
We study the variability of the quasar HS 1946+7658 on intra-night time scale based on both our own optical and archival X-ray data. We find the quasar non-variable during about 11…
The extreme HBL behaviour of Markarian 501 during 2012
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +276
A multiwavelength campaign was organized to take place between March and July of 2012. Excellent temporal coverage was obtained with more than 25 instruments, including the MAGIC,…
The ever-surprising blazar OJ 287: multi-wavelength study and appearance of a new component in X-rays
Pankaj Kushwaha, Alok C. Gupta, Paul J. Wiita +21
We present a multi-wavelength spectral and temporal investigation of OJ 287 emission during its strong optical-to-X-ray activity between July 2016 - July 2017. The daily -ray fl…
Characterizing optical variability of OJ 287 in 2016 - 2017
Alok C. Gupta, Haritma Gaur, Paul J. Wiita +22
We report on a recent multi-band optical photometric and polarimetric observational campaign of the blazar OJ 287 which was carried out during September 2016 -- December 2017. We e…
