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…
Polarization microvariability of BL Lac objects
I. Andruchow, G. E. Romero, S. A. Cellone
We present the results of a systematic observational campaign designed to search for microvariability in the optical polarization of BL Lac objects. We have observed a sample forme…
The WEBT campaign to observe AO 0235+16 in the 2003-2004 observing season
C. M. Raiteri, M. Villata, M. A. Ibrahimov +2
A multiwavelength campaign on the BL Lac object AO 0235+16 has been organized by the WEBT collaboration during the observing seasons 2003-2004 and 2004-2005. Here we report on the…
Optical microvariability of EGRET blazars
G. E. Romero, S. A. Cellone, J. A. Combi +1
We present results of a photometric CCD study of the incidence of microvariability in the optical emission of a sample of 20 blazars detected at gamma-ray energies by the EGRET ins…
