Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Tolga Guver, Tugba Boztepe, David R. Ballantyne, Z. Funda Bostanci, Peter Bult | Summary: We present spectral and temporal properties of all the thermonuclear X-ray bursts observed from Aql X-1 by the Neutron Star Interior and Composition Explorer (NICER) between 2017 July and 2021 April. This is […]
Kavli Affiliate: George Ricker | First 5 Authors: Rahul Jayaraman, Saul Rappaport, Lorne Nelson, Donald W. Kurtz, George Dufresne | Summary: Using the novel TESS 20-sec cadence data, we have discovered an unusual combination of pulsating stars in what we infer to be a binary system. The primary is a standard $delta$ Scuti star with […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Ian Wong, Avi Shporer, George Zhou, Daniel Kitzmann, Thaddeus D. Komacek | Summary: We report the discovery of an ultrahot Jupiter with an extremely short orbital period of $0.67247414,pm,0.00000028$ days ($sim$16 hr). The $1.347 pm 0.047$ $R_{rm Jup}$ planet, initially identified by the Transiting Exoplanet Survey […]
Kavli Affiliate: George Ricker | First 5 Authors: Rahul Jayaraman, Donald W. Kurtz, Gerald Handler, Saul Rappaport, George Ricker | Summary: We present two new rapidly oscillating Ap (roAp) stars, TIC 198781841 and TIC 229960986, discovered in TESS photometric data. The periodogram of TIC 198781841 has a large peak at 166.506 d$^{-1}$ (1.93 mHz), with […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Graham P. Smith, Timo Anguita, Simon Birrer, Paul L. Schechter, Aprajita Verma | Summary: We present the Strong Lensing Science Collaboration’s (SLSC) recommended observing targets for the science verification and science validation phases of commissioning. Our recommendations have been developed in collaboration with the Dark Energy […]

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Eve Schoen, Calvin Leung, Kiyoshi Masui, Daniele Michilli, Pragya Chawla | Summary: We describe a pipeline to measure scintillation in fast radio bursts (FRBs) detected by CHIME/FRB in the 400-800 MHz band by analyzing the frequency structure of the FRB’s spectrum. We use the pipeline to measure […]
Kavli Affiliate: Marshall Bautz | First 5 Authors: Charlotte Feldman, Paul O’Brien, Nicholas White, Wayne Baumgartner, Nicholas Thomas | Summary: The Lobster Eye X-ray Telescope (LEXT) is one of the payloads on-board the Gamow Explorer, which will be proposed to the 2021 NASA Explorer MIDEX opportunity. If approved, it will be launched in 2028, and […]
