X-ray and multiwavelength polarization of Mrk 501 from 2022 to 2023

Kavli Affiliate: Roger W. Romani | First 5 Authors: Chien-Ting J. Chen, Ioannis Liodakis, Riccardo Middei, Dawoon E. Kim, Laura Di Gesu | Summary: We present multiwavelength polarization measurements of the luminous blazar Mrk~501 over a 14-month period. The 2–8 keV X-ray polarization was measured with the Imaging X-ray Polarimetry Explorer (IXPE) with six 100-ks […]

Light Dark Matter Constraints from SuperCDMS HVeV Detectors Operated Underground with an Anticoincidence Event Selection

Kavli Affiliate: D. B. Macfarlane | First 5 Authors: SuperCDMS Collaboration, M. F. Albakry, I. Alkhatib, D. Alonso-González, D. W. P. Amaral | Summary: This article presents constraints on dark-matter-electron interactions obtained from the first underground data-taking campaign with multiple SuperCDMS HVeV detectors operated in the same housing. An exposure of 7.63 g-days is used […]

GD-1 Stellar Stream and Cocoon in the DESI Early Data Release

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Monica Valluri, Parker Fagrelius, Sergey. E. Koposov, Ting S. Li, Oleg Y. Gnedin | Summary: We present ~ 126 new spectroscopically identified members of the GD-1 tidal stream obtained with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence of a “cocoon” which is […]

The little coadd that could: Estimating shear from coadded images

Kavli Affiliate: Eli Rykoff | First 5 Authors: Robert Armstrong, Erin Sheldon, Eric Huff, Jim Bosch, Eli Rykoff | Summary: Upcoming wide field surveys will have many overlapping epochs of the same region of sky. The conventional wisdom is that in order to reduce the errors sufficiently for systematics-limited measurements, like weak lensing, we must […]

The Precursor Small Aperture Telescope (PreSAT) CMB polarimeter

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Matthew A. Petroff, Zeeshan Ahmed, James J. Bock, Marion Dierickx, Sofia Fatigoni | Summary: The search for the polarized imprint of primordial gravitational waves in the cosmic microwave background (CMB) as direct evidence of cosmic inflation requires exquisite sensitivity and control over systematics. The next-generation CMB-S4 project […]
