The complex light-curve of the afterglow of GRB071010A

S. Covino, P. D'Avanzo, A. Klotz +51

We present and discuss the results of an extensive observational campaign devoted to GRB071010A, a long-duration gamma-ray burst detected by the Swift satellite. This event was fol…

The afterglow onset for GRB060418 and GRB060607A

S. Covino, S. D. Vergani, D. Malesani +32

Gamma-ray burst are thought to be produced by highly relativistic outflows. Although upper and lower limits for the outflow initial Lorentz factor are available, observationa…

The GRB afterglow onset observed by REM: fireball Lorentz factor and afterglow fluence

Daniele Malesani, Emilio Molinari, Susanna Vergani +1

We report observations of the early light curves of GRB 060418 and GRB 060607A, carried out with the pink robotic telescope REM. A clear peak is detected for both events, which is…

REM near-IR and optical multiband observations of PKS2155-304 in 2005

A. Dolcini, F. Farfanelli, S. Ciprini +23

Spectral variability is the main tool for constraining emission models of BL Lac objects. By means of systematic observations of the BL Lac prototype PKS 2155-304 in the infrared-o…

REM observations of GRB 060418 and GRB 060607A: the onset of the afterglow and the initial fireball Lorentz factor determination

E. Molinari, S. D. Vergani, D. Malesani +32

Gamma-ray burst (GRB) emission is believed to originate in highly relativistic fireballs. Currently, only lower limits were securely set to the initial fireball Lorentz factor Gamm…

FAVOR (FAst Variability Optical Registration) -- A Two-telescope Complex for Detection and Investigation of Short Optical Transients

G. Beskin, V. Bad'in, A. Biryukov +25

An astronomical complex intended to detect optical transients (OTs) in a wide field and follow them up with high time resolution investigation is described.

A new concept and a preliminary design for a high resolution (HR) and very-high resolution (VHR) spectrograph for the LBT

F. M. Zerbi, P. Spano', P. Conconi +4

A way to fully exploit the large collecting area of modern 8-10m class telescopes is high resolution spectroscopy. Many astrophysical problems from planetary science to cosmology b…

REM - Rapid Eye Mount. A fast slewing robotized infrared telescope

Stefano Covino, Filippo Zerbi, Guido Chincarini +6

The main goal of the REM project is the observation of prompt afterglow of Gamma-Ray Burst (GRB) events. Such observations at Near InfraRed (NIR) wavelengths are even very promisin…

The BMW X-ray Cluster Survey

Alberto Moretti, Luigi Guzzo, Sergio Campana +7

We describe the main features of the BMW survey of serendipitous X-ray clusters, based on the still unexploited ROSAT-HRI archival observations. The sky coverage, surface density a…

The Composite Luminosity Function of A496

Emilio Molinari, Guido Chincarini, Alberto Moretti +1

Deep photometric observations in three colours of the cluster A 496 show that the luminosity function is bimodal with a deep gap at g about 19.0. That is there is a net separation…

Luminosity Function of Early-Type Galaxies in Clusters Cores

Emilio Molinari, Riccardo Smareglia

We show the possibility to exploit the non-linear behaviour of artificial neural network (ANN) for the identification of the early-type component of the population of the core of c…
