Kavli Affiliate: Anthony Challinor | First 5 Authors: Íñigo Zubeldia, Anthony Challinor, , , | Summary: CMB lensing is a promising, novel way to measure galaxy cluster masses that can be used, e.g., for mass calibration in galaxy cluster counts analyses. Understanding the statistics of the galaxy cluster mass observable obtained with such measurements is […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: SuperCDMS Collaboration, D. W. Amaral, T. Aralis, T. Aramaki, I. J. Arnquist | Summary: This article presents an analysis and the resulting limits on light dark matter inelastically scattering off of electrons, and on dark photon and axion-like particle absorption, using a second-generation SuperCDMS high-voltage eV-resolution […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Martijn de Vries, Roger W. Romani, , , | Summary: We report on new X-ray and optical observations of PSR J2030+4415, a Gamma-ray Pulsar with an H$alpha$ bow shock. These data reveal the velocity structure of the bow shock apex and resolve unusual X-ray structure in […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Hongye Yu, Frank Wilczek, Biao Wu, , | Summary: We present a quantum algorithm for approximating maximum independent sets of a graph based on quantum non-Abelian adiabatic mixing in the sub-Hilbert space of degenerate ground states, which generates quantum annealing in a secondary Hamiltonian. For both sparse […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Chuneeta D. Nunhokee, Aaron R. Parsons, Nicholas S. Kern, Bojan Nikolic, Jonathan C. Pober | Summary: The central challenge in 21~cm cosmology is isolating the cosmological signal from bright foregrounds. Many separation techniques rely on the accurate knowledge of the sky and the instrumental response, including […]
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: Qingjuan Yu | First 5 Authors: Yunfeng Chen, Qingjuan Yu, Youjun Lu, , | Summary: We investigate the evolution of supermassive binary black holes (BBHs) in galaxies with realistic property distributions and the gravitational-wave (GW) radiation from the cosmic population of these BBHs. We incorporate a comprehensive treatment of the dynamical interactions of […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Nithyanandan Thyagarajan, Chris L. Carilli, Bojan Nikolic, James Kent, Andrei Mesinger | Summary: Characterizing the epoch of reionization (EoR) at $zgtrsim 6$ via the redshifted 21 cm line of neutral Hydrogen (HI) is critical to modern astrophysics and cosmology, and thus a key science goal of […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Roxana Rosca-Mead, Ulrich Sperhake, Christopher J. Moore, Michalis Agathos, Davide Gerosa | Summary: This paper provides an extended exploration of the inverse-chirp gravitational-wave signals from stellar collapse in massive scalar-tensor gravity reported in [Phys. Rev. Lett. {bf 119}, 201103]. We systematically explore the parameter space that characterizes […]
