Background-Limited Imaging in the Near-Infrared with Warm InGaAs Sensors: Applications for Time-Domain Astronomy
Robert A. Simcoe, Gabor Furesz, Peter W. Sullivan +6
We describe test observations made with a customized 640 x 512 pixel Indium Gallium Arsenide (InGaAs) prototype astronomical camera on the 100" DuPont telescope. This is the first…
IGM Emission Observations with the Cosmic Web Imager: I. The Circum-QSO Medium of QSO 1549+19, and Evidence for a Filamentary Gas Inflow
D. Christopher Martin, Daphne Chang, Matt Matuszewski +4
The Palomar Cosmic Web Imager (PCWI), an integral field spectrograph designed to detect and map low surface brightness emission, has obtained imaging spectroscopic maps of Ly-alpha…
Progenitor and Close-In Circumstellar Medium of Type II Supernova 2020fqv from High-Cadence Photometry and Ultra-Rapid UV Spectroscopy
Samaporn Tinyanont, Ryan Ridden-Harper, Ryan Foley +35
We present observations of SN 2020fqv, a Virgo-cluster Type II core-collapse supernova (CCSN) with a high temporal resolution light curve from the Transiting Exoplanet Survey Satel…
The Dynamic Infrared Sky
Mansi M. Kasliwal, Scott Adams, Igor Andreoni +16
Opening up the dynamic infrared sky for systematic time-domain exploration would yield many scientific advances. Multi-messenger pursuits such as localizing gravitational waves fro…
Voyage 2050 White Paper: All-Sky Visible and Near Infrared Space Astrometry
David Hobbs, Anthony Brown, Erik Høg +27
A new all-sky visible and Near-InfraRed (NIR) space astrometry mission with a wavelength cutoff in the K-band is not just focused on a single or small number of key science cases.…
SPIRITS: Uncovering Unusual Infrared Transients With Spitzer
Mansi M. Kasliwal, John Bally, Frank Masci +44
We present an ongoing, systematic search for extragalactic infrared transients, dubbed SPIRITS --- SPitzer InfraRed Intensive Transients Survey. In the first year, using Spitzer/IR…
