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 […]

Uncovering the true periods of the young sub-Neptunes orbiting TOI-2076

Kavli Affiliate: Avi Shporer | First 5 Authors: Hugh P. Osborn, Andrea Bonfanti, Davide Gandolfi, Christina Hedges, Adrien Leleu | Summary: Context: TOI-2076 is a transiting three-planet system of sub-Neptunes orbiting a bright (G = 8.9 mag), young ($340pm80$ Myr) K-type star. Although a validated planetary system, the orbits of the two outer planets were […]
