Constraints on low-mass, relic dark matter candidates from a surface-operated SuperCDMS single-charge sensitive detector

Posted by klaurent Stanford

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 […]

A model for the fragmentation kinetics of crumpled thin sheets

Posted by klaurent Harvard

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Jovana Andrejevic, Lisa M. Lee, Shmuel M. Rubinstein, Chris H. Rycroft, | Summary: As a confined thin sheet crumples, it spontaneously segments into flat facets delimited by a network of ridges. Despite the apparent disorder of this process, statistical properties of crumpled sheets exhibit striking reproducibility. […]

Measuring HERA’s primary beam in-situ: methodology and first results

Posted by klaurent MIT

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 […]

HD 62542: Probing the Bare, Dense Core of a Translucent Interstellar Cloud

Posted by klaurent Chicago

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 […]

Dynamical evolution of cosmic supermassive binary black holes and their gravitational wave radiation

Posted by klaurent Peking

Kavli Affiliate: Qingjuan Yu | 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 the BBHs with their environments by including the effects of galaxy triaxial […]

Detection of Cosmic Structures using the Bispectrum Phase. II. First Results from Application to Cosmic Reionization Using the Hydrogen Epoch of Reionization Array

Posted by klaurent MIT

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 […]

Holistic Parameteric Reconstruction of Building Models from Point Clouds

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Zhixin Li, Zhixin Li, , , | Summary: Building models are conventionally reconstructed by building roof points planar segmentation and then using a topology graph to group the planes together. Roof edges and vertices are then mathematically represented by intersecting segmented planes. Technically, such solution is based […]

Global inducing point variational posteriors for Bayesian neural networks and deep Gaussian processes

Posted by klaurent Cornell

Kavli Affiliate: Christopher Ober| First 5 Authors: Sebastian W. Ober, Sebastian W. Ober, , , | Summary:We consider the optimal approximate posterior over the top-layer weights in a Bayesian neural network for regression, and show that it exhibits strong dependencies on the lower-layer weights. We adapt this result to develop a correlated approximate posterior over […]
