Rapid GRB Photometry with RIMAS
Abstract
The Rapid infrared IMAger-Spectrometer (RIMAS) is a quick near-infrared gamma-ray burst (GRB) afterglow follow-up instrument that can be run in either photometric imaging mode or spectroscopy mode. RIMAS covers four photometric bands: Y (0.97-1.08 um), J (1.11-1.33 um), H (1.48-1.78 um), and K (2.00-2.39 um). The wavelength coverage is separated into two optical arms (YJ and HK) and can acquire simultaneously between arms. When RIMAS is run in photometric imaging mode, we will be able to identify GRB afterglows and calculate redshifts for GRBs with Lyman alpha breaks. We present the status of RIMAS’s detector development that consists of a guiding InSb detector and two HgCdTe 2k x 2k (H2RG) detectors as well as current noise characterization results. We report RIMAS’s photometric imaging limiting magnitude estimates and comparisons between RIMAS and other near-infrared GRB afterglow imaging instruments.
