Abstract

During the last years, a number of telescopes have been dedicated to the followup of the GRBs. But after the Swift launch, the average observed intensity of the GRBs showed to be lower than thought before. Our experience with the robotic 60 cm REM telescope confirmed this evidence, with a large number of lost GRBs. Then, we proposed to study the feasibility of a 4 m fast pointing class telescope, equipped with a multichannel imagers, from Visible to Near Infrared. In this paper, we present the main result of the feasibility study we performed so far.

Highlights

  • Since the discovery of a dynamic Universe on time scales of hours and seconds it became of paramount importance to have a high sampling frequency of the data

  • We present the main result of the feasibility study we performed so far

  • We present here the feasibility study of a robotic 4 m class telescope able to point and track everywhere in the visible sky in 30–50 s, equipped with multichannel VIS and NIR imagers, allowing simultaneous observations from 0.4 to 2.5 μm, and visible spectrometer and polarimeter ancillary instruments
