Observations of the prompt afterglow of Gamma Ray Burst events are of paramount importance for GRB science and cosmology. In particular early observations at NIR wavelengths are even more promising allowing one to discover and monitor high-z Ly-alpha absorbed bursts as well as events occurring in dusty star-forming regions. In these pages we present REM (Rapid Eye Mount), a fully robotized fast slewing telescope equipped with a high throughput NIR (Z', J, H, K') camera (REMIR) and an Optical Slitless Spectrograph (ROSS), dedicated to detect and study prompt IR and optical afterglow. The REM telescope will simultaneously feed REMIR and ROSS via a dichroic. The synergy between the REMIR camera and the ROSS spectrograph makes REM a powerful observing tool for any kind of fast transient phenomena providing an unprecedented simultaneous wavelength coverage on a telescope of this size. Beside its ambitious scientific goals, REM is also technically challenging since it represent the first attempt to locate a NIR camera on such a small telescope.

Abstract
Observations of the prompt afterglow of Gamma Ray Burst events are of paramount importance for GRB science and cosmology. In particular early observations at NIR wavelengths are even more promising allowing one to discover and monitor high-z Ly-alpha absorbed bursts as well as events occurring in dusty star-forming regions. In these pages we present REM (Rapid Eye Mount), a fully robotized fast slewing telescope equipped with a high throughput NIR (Z', J, H, K') camera (REMIR) and an Optical Slitless Spectrograph (ROSS), dedicated to detect and study prompt IR and optical afterglow. The REM telescope will simultaneously feed REMIR and ROSS via a dichroic. The synergy between the REMIR camera and the ROSS spectrograph makes REM a powerful observing tool for any kind of fast transient phenomena providing an unprecedented simultaneous wavelength coverage on a telescope of this size. Beside its ambitious scientific goals, REM is also technically challenging since it represent the first attempt to locate a NIR camera on such a small telescope.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
