LSQ13dsm is a pre-maximum type Ia supernova, classification by FIRE near-infrared spectroscopy
Abstract
We report the spectroscopic classification of LSQ13dsm using a near-infrared spectrum (range 800-2500 nm) obtained on Jan 1.21 UT with the FoldedPort Infrared Echellette (FIRE) spectrograph on the 6.5-m Magellan Baade Telescope at Las Campanas Observatory. The near-infrared spectrum shows that LSQ13dsm is a young type Ia supernova at approximately z=0.04.
