VizieR Online Data Catalog: Follow-up phot. & sp. of 12 PGIR novae (De+, 2021)

In this paper, we present a sample of 12 spectroscopically confirmed novae detected in the first 17 months -- between 2019 July 2 (the start date of the survey when the reference image construction was completed) and 2020 November 30 (the end of the 2020 Galactic bulge season in the northern hemisphere) -- of the Palomar Gattini-IR (PGIR) NIR time-domain survey (Moore & Kasliwal 2019NatAs...3..109M and De+ 2020PASP..132b5001D). PGIR is a robotic, wide-field time-domain survey at the Palomar Observatory using a 25deg² J-band camera to survey the entire northern visible sky (δ>-28.9°; ~15000deg²) at a cadence of ~2 nights.

In order to determine spectroscopic classifications of confirmed novae, we obtained medium resolution optical and IR spectroscopic follow-up (see Figure 3) using the Palomar 200 inch telescope (P200) using the optical Double Spectrograph (DBSP) and NIR Triple spectrograph (TSpec) at the Palomar Observatory, the NASA Infrared Telescope Facility (IRTF) and Keck I telescopes at Maunakea, and the Australian National University 2.3m telescope at Siding Spring Observatory (SSO) using the Wide-field Spectrograph (WiFeS). The IRTF data were acquired with the SpeX instrument in the SXD mode (~0.7-2.5um) as part of programs 2020A111 and 2020B087 (PI: K. De). The Keck spectrum of PGIR 20ekz was acquired using the Low Resolution Imaging Spectrometer (LRIS).
