Title: Early Optical Afterglows of GRBs with 2-m Robotic Telescopes 

Date: Wednesday, February 27th, 2008 
Time: 12:00 
Venue: Villa Bazzoni (Via Bazzoni, 2)

*********************************************************** 
Abstract: 
In last three years many new insights into Gamma Ray Bursts (GRBs) physics have been brought by the Swift satellite. Rapid and accurate localization of GRBs by the Swift enables rapid response ground-based telescopes to routinely commence with observations of optical afterglows within minutes after the burst. The combination of gamma-ray, X-ray, optical and ultraviolet data from Swift instruments with deep, early-time optical imaging from ground-based telescopes is providing unprecedented multiwavelength datasets. 
I will present the observational strategy and some results of rapid, automatic, optical follow-up observations of a sample of GRBs using the 2-m robotic Liverpool and Faulkes Telescopes. The observations are carried out from minutes to a few hours after the prompt GRB and result in well-sampled light curves. I will review and discuss possible interpretation of the large variety in early afterglow behaviour.

Title: Abundance of heavy elements in extremely metal-poor stars 

Date: Wednesday, March 5th, 2008 
Time: 12:00 
Venue: Villa Bazzoni 

*********************************************************** 
Abstract: 
35 night of VLT observing time has been used to study the chemical composition of extremely metal-poor stars. These stars are living witnesses of the early stages of the galactic evolution. High resolution, high S/N spectra have been obtained with UVES, the high resolution spectrograph attached to Kueyen, the second unit of the Very Large Telescope. In this talk, I will report on the determination of the abundance of the neutron-capture elements. The results will be discussed in the light of the current knowledge of s-process and r-process nucleosynthesis.
