Since its discovery in 1992, the superluminal X-ray transient GRS 1915+105 has been extensively observed in an attempt to understand its behaviour. We present...
Multiwavelength observations of the February 1996 high-energy flare in the blazar 3C 279
We report CGRO, RXTE, ASCA, ROSAT, IUE, HST and ground-based observations of a large flare in 3C 279 in February 1996. X-rays and γ-rays peaked simultaneously...
Observation and Upper Limits of GRBs with the MAGIC Telescope
After three years since the beginning of operation, the MAGIC telescope could observe several GRB events in the prompt and early afterglow phase. Thanks to its...
Observation of gamma ray bursts at very high energies with the MAGIC telescope
The detection of the Very High Energy (VHE) emission from Gamma Ray Bursts (GRBs) is desired, as it will provide an unprecedented opportunity to enlighten the...
After three years since the beginning of operation, the MAGIC telescope could observe several GRB events in the prompt and early afterglow phase. Thanks to its...
Observations of Optical Afterglows of Gamma-Ray Bursts from Loiano
We report on our program for multiband photometry observations of Optical Transients of Gamma-Ray Bursts at the 152 cm telescope in Loiano. 40 Km south of...
Observations of the Crab Nebula and Pulsar with the Large-sized Telescope Prototype of the Cherenkov Telescope Array
The Cherenkov Telescope Array (CTA) is a next-generation ground-based observatory for gamma-ray astronomy at very high energies. The Large-Sized Telescope...
Using the Nordic Optical Telescope, La Palma, Spain, optical studies of OT/GRB970508 were initiated 3 hours 5 minutes after the high energy event (This appears...
We report on the results of optical follow-up observations of the counterpart of GRB970508 between 7 hours and 100 days after the event. Multi-colour U, B, V...
