Unveiling the nature of INTEGRAL objects through optical spectroscopy. VI. A multi-observatory identification campaign
N. Masetti, E. Mason, L. Morelli +18
Using 8 telescopes in the northern and southern hemispheres, plus archival data from two on-line sky surveys, we performed a systematic optical spectroscopic study of 39 putative c…
Extreme photo-polarimetric behaviour of the blazar AO 0235+164
Sergio A. Cellone, Gustavo E. Romero, Jorge A. Combi +1
We present optical photo-polarimetric observations with high temporal resolution of the blazar AO 0235+164. Our data, the first to test the photo-polarimetric behaviour of this obj…
Extremely violent optical microvariability in blazars: fact or fiction?
Sergio A. Cellone, Gustavo E. Romero, Anabella T. Araudo
Variability amplitudes larger than 1 magnitude over time-scales of a few tens of minutes have recently been reported in the optical light-curves of several blazars. In order to ind…
