Hi, I'm Kylie, a senior at MIT studying physics, astronomy, and Japanese. This was the work I did at WAVE, an REU at Caltech, last summer!
Palomar Gattini-IR (PGIR) uses a small, 30-cm telescope with a field of view of 25 square degrees. PGIR has a “Fast Readout Mode” with a short exposure time of about 0.82 seconds, allowing one to study very fast time domain phenomena which change over timescales ranging from a few seconds to even a few tens of milliseconds. As PGIR takes data in the infrared, it can peer into areas of the universe obscured by dust. The Fast Readout Mode was utilized to take data of nova V1674 Her (Nova Her 2021), searching for short timescale structure in the nova’s lightcurve. Both PSF and aperture photometry were performed on the nova; PSF photometry was shown to be unreliable due to variance in sensitivity across individual pixels. Image subtraction was also performed to search for unknown transients, and preliminary results are discussed.
