Revisiting Kepler Transiting Systems: Unvetting Planets and Constraining Relationships among Harmonics in Phase Curves

Kavli Affiliate: Avi Shporer | First 5 Authors: Prajwal Niraula, Avi Shporer, Ian Wong, Julien de Wit, | Summary: Space-based photometric missions widely use statistical validation tools for vetting transiting planetary candidates, particularly when other traditional methods of planet confirmation are unviable. In this paper, we refute the planetary nature of three previously validated planets […]

Removing systematics-induced 21-cm foreground residuals by cross-correlating filtered data

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Haochen Wang, Juan Mena-Parra, Tianyue Chen, Kiyoshi Masui, | Summary: Observations of the redshifted 21-cm signal emitted by neutral hydrogen represent a promising probe of large-scale structure in the universe. However, cosmological 21-cm signal is challenging to observe due to astrophysical foregrounds which are several orders of […]

Snowmass2021 Cosmic Frontier: Synergies between dark matter searches and multiwavelength/multimessenger astrophysics

Kavli Affiliate: Lina Necib | First 5 Authors: Shin’ichiro Ando, Sebastian Baum, Michael Boylan-Kolchin, Esra Bulbul, Michael Burgess | Summary: This whitepaper focuses on the astrophysical systematics which are encountered in dark matter searches. Oftentimes in indirect and also in direct dark matter searches, astrophysical systematics are a major limiting factor to sensitivity to dark […]

Tidally Tilted Pulsations in HD 265435, a subdwarf B Star with a Close White Dwarf Companion

Kavli Affiliate: George Ricker | First 5 Authors: Rahul Jayaraman, Gerald Handler, Saul Rappaport, Jim Fuller, Donald W. Kurtz | Summary: Tidally tilted pulsators (TTPs) are an intriguing new class of oscillating stars in binary systems; in such stars, the pulsation axis coincides with the line of apsides, or semi-major axis, of the binary. All […]

TOI-1670 b and c: An Inner Sub-Neptune with an Outer Warm Jupiter Unlikely to have Originated from High-Eccentricity Migration

Kavli Affiliate: George R. Ricker | First 5 Authors: Quang H. Tran, Brendan P. Bowler, Michael Endl, William D. Cochran, Phillip J. MacQueen | Summary: We report the discovery of two transiting planets around the bright ($V=9.9$ mag) main sequence F7 star TOI-1670 by the Transiting Exoplanet Survey Satellite. TOI-1670 b is a sub-Neptune ($R_mathrm{b} […]

Probing squeezing for gravitational-wave detectors with an audio-band field

Kavli Affiliate: Lisa Barsotti | First 5 Authors: Dhruva Ganapathy, Victoria Xu, Wenxuan Jia, Chris Whittle, Maggie Tse | Summary: Squeezed vacuum states are now employed in gravitational-wave interferometric detectors, enhancing their sensitivity and thus enabling richer astrophysical observations. In future observing runs, the detectors will incorporate a filter cavity to suppress quantum radiation pressure […]
