Kavli Affiliate: Craig J. Hogan | First 5 Authors: Zimu Khakhaleva-Li, Craig J. Hogan, , , | Summary: Rapid advancement in the observation of cosmic strings has been made in recent years placing increasingly stringent constraints on their properties, with $Gmulesssim 10^{-11}$ from Pulsar Timing Array (PTA). Cosmic string loops with low string tension clump […]
Kavli Affiliate: Elise Jennings | First 5 Authors: Himanshu Sharma, Elise Jennings, , , | Summary: Bayesian neural Networks (BNNs) are a promising method of obtaining statistical uncertainties for neural network predictions but with a higher computational overhead which can limit their practical usage. This work explores the use of high performance computing with distributed […]
Kavli Affiliate: Donald G. York | First 5 Authors: Daniel E. Welty, Paule Sonnentrucker, Theodore P. Snow, Donald G. York, | Summary: We discuss the interstellar absorption from many atomic and molecular species seen in high-resolution $HST$/STIS UV and high-S/N optical spectra of the moderately reddened B3-5~V star HD~62542. This remarkable sight line exhibits both […]
Kavli Affiliate: Austin Joyce | First 5 Authors: Daniel Baumann, Carlos Duaso Pueyo, Austin Joyce, Hayden Lee, Guilherme L. Pimentel | Summary: We extend the cosmological bootstrap to correlators involving massless particles with spin. In de Sitter space, these correlators are constrained both by symmetries and by locality. In particular, the de Sitter isometries become […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: T. Daniel Brennan, Christian Ferko, Emil Martinec, Savdeep Sethi, | Summary: We show that the $T overline{T}$ deformation of two-dimensional quantum field theory on $mathrm{AdS}_2$ is well-defined and solvable at the quantum level. Flow equations for the energy spectrum and partition function are derived in analogy with […]
Kavli Affiliate: Abigail Vieregg | First 5 Authors: Stephanie Wissel, Andrés Romero-Wolf, Harm Schoorlemmer, Washington R. Carvalho Jr., Jaime Alvarez-Muñiz | Summary: Tau neutrinos are expected to comprise roughly one third of both the astrophysical and cosmogenic neutrino flux, but currently the flavor ratio is poorly constrained and the expected flux at energies above $10^{17}$ […]
Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Mariano Cababie, Gustavo Cancelo, Luke Chaplinsky | Summary: We present the first direct-detection search for eV-to-GeV dark matter using a new ~2-gram high-resistivity Skipper-CCD from a dedicated fabrication batch that was optimized for dark-matter searches. Using 24 days of data acquired in […]
Kavli Affiliate: Donald G. York | First 5 Authors: David V. Bowen, Todd M. Tripp, Edward B. Jenkins, Max Pettini, Doron Chelouche | Summary: We present an HST Cosmic Origins Spectrograph (COS) spectrum of the QSO SDSS J095109.12+330745.8 ($z_{em} = 0.645$) whose sightline passes through the SMC-like dwarf galaxy UGC 5282 ($M_B = -16.0$, $cz […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Zack Li, Sigurd Naess, Simone Aiola, David Alonso, John W. Appel | Summary: One of the most important checks for systematic errors in CMB studies is the cross correlation of maps made by independent experiments. In this paper we report on the cross correlation between maps from […]
Kavli Affiliate: Angela Olinto | First 5 Authors: Martin Elvis, Jon Arenberg, David Ballantyne, Mark Bautz, Charles Beichman | Summary: Astrophysics spans an enormous range of questions on scales from individual planets to the entire cosmos. To address the richness of 21st century astrophysics requires a corresponding richness of telescopes spanning all bands and all […]
