Kavli Affiliate: Adam B. Mantz | First 5 Authors: Jenny T. Wan, Adam B. Mantz, Jack Sayers, Steven W. Allen, R. Glenn Morris | Summary: We use a sample of 14 massive, dynamically relaxed galaxy clusters to constrain the Hubble Constant, $H_0$, by combining X-ray and Sunyaev-Zel’dovich (SZ) effect signals measured with Chandra, Planck and […]
Kavli Affiliate: Tom Abel | First 5 Authors: Daegene Koh, Tom Abel, Karsten Jedamzik, , | Summary: It has been recently claimed that primordial magnetic fields could relieve the cosmological Hubble tension. We consider the impact of such fields on the formation of the first cosmological objects, mini-halos forming stars, for present-day field strengths in […]
Kavli Affiliate: T. A. Shutt | First 5 Authors: D. S. Akerib, A. K. Al Musalhi, S. K. Alsum, C. S. Amarasinghe, A. Ames | Summary: Two-phase xenon detectors, such as that at the core of the forthcoming LZ dark matter experiment, use photomultiplier tubes to sense the primary (S1) and secondary (S2) scintillation signals […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Yonit Hochberg, Yonatan Kahn, Noah Kurinsky, Benjamin V. Lehmann, To Chin Yu | Summary: We show that the rate for dark matter-electron scattering in an arbitrary material is determined by an experimentally measurable quantity, the complex dielectric function, for any dark matter interaction that couples to electron […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Simon Birrer, Daniel Gilman, Risa H. Wechsler, Xiaolong Du | Summary: Joint analyses of small-scale cosmological structure probes are relatively unexplored and promise to advance measurements of microphysical dark matter properties using heterogeneous data. Here, we present a multidimensional analysis of dark matter […]
Kavli Affiliate: George Clark | First 5 Authors: George Clark, Alex Gonye, Steven J Miller, , | Summary: During World War II the German army used tanks to devastating advantage. The Allies needed accurate estimates of their tank production and deployment. They used two approaches to find these values: spies, and statistics. This note describes […]
Kavli Affiliate: John Silverman | First 5 Authors: Daizhong Liu, Emanuele Daddi, Eva Schinnerer, Toshiki Saito, Adam Leroy | Summary: We study the Carbon Monoxide (CO) excitation, mean molecular gas density and interstellar radiation field (ISRF) intensity in a comprehensive sample of 76 galaxies from local to high redshift (z~0-6), selected based on detections of […]
Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Mason Ng, Paul S. Ray, Peter Bult, Deepto Chakrabarty, Gaurava K. Jaisawal | Summary: We report the detection of 376.05 Hz (2.66 ms) coherent X-ray pulsations in NICER observations of a transient outburst of the low-mass X-ray binary IGR J17494-3030 in 2020 October/November. The system is an […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Jamila Pegues, Ian Czekala, Sean M. Andrews, Karin I. Öberg, Gregory J. Herczeg | Summary: In this era of Gaia and ALMA, dynamical stellar mass measurements provide benchmarks that are independent of observations of stellar characteristics and their uncertainties. These benchmarks can then be used to […]
