Near Infrared Spectroscopic Monitoring of EXor variables: First Results
D. Lorenzetti, V. M. Larionov, T. Giannini +4
We present low resolution (R approximately 250) spectroscopy in the near-IR (0.8 to 2.5um) of the EXor variables. These are the initial results (obtained during the period 2007-200…
The WEBT Campaign on the Intermediate BL Lac Object 3C66A in 2007-2008
M. Boettcher, K. Fultz
Prompted by a high optical state in September 2007, the Whole Earth Blazar Telescope (WEBT) consortium organized an intensive optical, near-IR (JHK) and radio observing campaign on…
WEBT and XMM-Newton observations of 3C 454.3 during the post-outburst phase. Detection of the little and big blue bumps
C. M. Raiteri, M. Villata, V. M. Larionov +3
The blazar 3C 454.3 underwent an unprecedented optical outburst in spring 2005. This was first followed by a mm and then by a cm radio outburst, which peaked in February 2006. We r…
An infrared view of the EXor variables: on the case of V1118 ORI
D. Lorenzetti, T. Giannini, V. M. Larionov +4
We investigate the relationship between the IR observed properties of the EXor variables and the mechanisms active during their evolutionary stage. To this aim, we have constructed…
A flash in the dark: UVES/VLT high resolution spectroscopy of GRB afterglows
F. Fiore, V. D'Elia, D. Lazzati +17
We present the first high resolution (R=20000--45000, corresponding to 14 km/s at 4200A to 6.6 km/s at 9000A) observations of the optical afterglow of Gamma Ray Bursts. GRB020813 a…
Digitatio and Scientific Exploitation of the Italian and Vatican Astronomical Plate Archives
C. Barbieri
There is a widespread interest to digitize the precious information contained in the astronomical plate archives, both for the preservation of their content and for its fast distri…
Optical and near-infrared photometry of the Type Ia Supernova 2000E in NGC 6951
G. Valentini, E. Di Carlo, F. Massi +15
We present optical and near-infrared photometry, along with optical spectra, of the Type Ia supernova SN 2000E in the spiral galaxy NGC 6951. It was discovered by the staff of the…
Discovery of the heavily obscured supernova 2002cv
A. Di Paola, V. Larionov, A. Arkharov +5
On the 13th of May 2002, supernova 2002cv was discovered using a near-infrared camera working at the AZT-24 1.1m telescope at Campo Imperatore (AQ-Italy). After the infrared detect…
Optical and infrared observations of the supernova SN 1999el
E. Di Carlo, F. Massi, G. Valentini +22
Optical and near-infrared light curves of the Type IIn supernova 1999el in NGC 6951 are presented. A period of 220 days (416 days in the near-infrared) is covered from the first ob…
GRB010222: afterglow emission from a rapidly decelerating shock
N. Masetti
The GRB010222 optical and near-infrared (NIR) afterglow was monitored at the TNG and other Italian telescopes starting ~1 day after the high-energy prompt event. The optical BVR li…
The discovery of the optical/IR counterpart of the 12s transient X-ray pulsar GS 0834-43
G. L. Israel, S. Covino, S. Campana +9
We report the discovery of the optical/infra-red counterpart of the 12.3s transient X-ray pulsar GS0834-43. We re-analysed archival ROSAT PSPC observations of GS0834-43, obtaining…
