RESEARCH  INTERESTS:

1. GAMMA RAY BURST:

Our group has given significant contributions in this field of research, obtaining the earliest photometry of GRB 970228, the first for which an optical counterpart was identified. We followed up the Optical Transient of many other GRBs.

 

In the animation the explosion and the light curve of a Gamma-ray Burst(GRB) is presented.GRBs are the strongest explosions in the Universe after the Big Bang and are one of the most fascinating problems of Astrophysics, the "engine" producing these explosions because is still unknown.
 


2. X-RAY BINARIES:

The X-ray binaries produce high energy photons because matter coming from the normal star falls onto a collapsed stars: Black Hole (BH) or Neutron Stars (NS). We obtained photometry and spectroscopy of such as systems; V725 Tauri, optical counterpart of A0535+26, is observed since about 28 years.

3. CLASSICAL ECLIPSING BINARIES

Very accurate photometry of classical eclipsing binaries as XY Leonis was achieved by means of a two head photometer mounted on the 1.5m telescope of the observatory of Loiano.
