Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: The CHIME/FRB Collaboration, :, Mandana Amiri, Bridget C. Andersen, Kevin Bandura | Summary: We present a catalog of 536 fast radio bursts (FRBs) detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project between 400 and 800 MHz from 2018 July 25 to […]
Kavli Affiliate: Saul Rappaport | First 5 Authors: Zachary P. Vanderbosch, Saul Rappaport, Joseph A. Guidry, Bruce L. Gary, Simon Blouin | Summary: We present follow-up photometry and spectroscopy of ZTF J0328$-$1219 strengthening its status as a white dwarf exhibiting transiting planetary debris. Using TESS and Zwicky Transient Facility photometry, along with follow-up high speed […]
Kavli Affiliate: Eric Miller | First 5 Authors: Yukikatsu Terada, Matt Holland, Michael Loewenstein, Makoto Tashiro, Hiromitsu Takahashi | Summary: XRISM is an X-ray astronomical mission by the JAXA, NASA, ESA and other international participants, that is planned for launch in 2022 (Japanese fiscal year), to quickly restore high-resolution X-ray spectroscopy of astrophysical objects. To […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Thomas A. Callister, Carl-Johan Haster, Ken K. Y. Ng, Salvatore Vitale, Will M. Farr | Summary: Hierarchical analysis of the binary black hole (BBH) detections by the Advanced LIGO and Virgo detectors has offered an increasingly clear picture of their mass, spin, and redshift distributions. Fully understanding […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Bohan Wang, Qi Meng, Wei Chen, Max Tegmark | Summary: Energy conservation is a basic physics principle, the breakdown of which often implies new physics. This paper presents a method for data-driven "new physics" discovery. Specifically, given a trajectory governed by unknown forces, our Neural […]
Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Veselin B. Kostov, Brian P. Powell, Guillermo Torres, Tamas Borkovits, Saul A. Rappaport | Summary: We report the discovery of a compact, coplanar, quadruply-lined, eclipsing quadruple star system from TESS data, TIC 454140642, also known as TYC 0074-01254-1. The target was first detected in Sector 5 […]
Kavli Affiliate: Gregory Y. Prigozhin | First 5 Authors: Ronald A. Remillard, Michael Loewenstein, James F. Steiner, Gregory Y. Prigozhin, Beverly LaMarr | Summary: NICER has a comparatively low background rate, but it is highly variable, and its spectrum must be predicted using measurements unaffected by the science target. We describe an empirical, three-parameter model […]
Kavli Affiliate: Paul Schechter | First 5 Authors: Luke Weisenbach, Paul Schechter, Sahil Pontula, , | Summary: Although micro-lensing of macro-lensed quasars and supernovae provides unique opportunities for several kinds of investigations, it can add unwanted and sometimes substantial noise. While micro-lensing flux anomalies may be safely ignored for some observations, they severely limit others. […]

Kavli Affiliate: Gabor Furesz | First 5 Authors: Veselin B. Kostov, Brian P. Powell, Jerome A. Orosz, William F. Welsh, William Cochran | Summary: We report the first discovery of a transiting circumbinary planet detected from a single sector of TESS data. During Sector 21, the planet TIC 172900988b transited the primary star and then […]
