Abstract

In this age of multi-messenger astronomy precipitated by the LIGO/Virgo observation of GW 170817, it is more important than ever to have instruments throughout the EM spectrum to perform follow-up observations. With the installation of an upgraded detector system and cross-dispersed ruled ZnSe grisms, and development of data reduction pipelines, the Rapid infrared IMAger Spectrometer (RIMAS) is ready to be at the frontier of this rapidly blossoming field. RIMAS is a near-infrared imager spectrometer (R≈25, R≈250, and R≈4000) designed to observe the afterglows of high-redshift GRBs in the Y, J, H and K bands once installed on the 4.3 meter Lowell Discovery Telescope located outside Flagstaff, AZ. In this paper, we discuss the performance of RIMAS’s high resolution spectrograph, which is enabled through the use of ruled ZnSe grisms working in high order echelle mode.
