Kavli Affiliate: Scott K. Cushing | First 5 Authors: Hanzhe Liu, Isabel M. Klein, Jonathan M. Michelsen, Scott K. Cushing, | Summary: Transient X-ray absorption techniques can measure ultrafast dynamics of the elemental edges in a material or multiple layer junction, giving them immense potential for deconvoluting concurrent processes. However, the interpretation of the photoexcited […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Fakhri S. Zahedy, Hsiao-Wen Chen, Thomas M. Cooper, Erin T. Boettcher, Sean D. Johnson | Summary: (Abridged) We present a systematic investigation of physical conditions and elemental abundances in four optically thick Lyman-limit systems (LLSs) at $z=0.36-0.6$ discovered within the Cosmic Ultraviolet Baryon Survey (CUBS). CUBS […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Curtis McCully, Saurabh W. Jha, Richard A. Scalzo, D. Andrew Howell, Ryan J. Foley | Summary: Type Iax supernovae represent the largest class of peculiar white-dwarf supernovae. The type Iax SN~2012Z in NGC 1309 is the only white dwarf supernova with a detected progenitor system in pre-explosion […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Anna-Christina Eilers, Joseph F. Hennawi, Frederick B. Davies, Robert A. Simcoe, | Summary: The extents of proximity zones of high-redshift quasars enable constraints on the timescales of quasar activity, which are fundamental for understanding the growth of the supermassive black holes (SMBHs) that power the quasars’ […]
Kavli Affiliate: George Ricker | First 5 Authors: Étienne Artigau, Guillaume Hébrard, Charles Cadieux, Thomas Vandal, Neil J. Cook | Summary: We present the discovery of an $18.5pm0.5$M$_{rm Jup}$ brown dwarf (BD) companion to the M0V star TOI-1278. The system was first identified through a percent-deep transit in TESS photometry; further analysis showed it to […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Claire Guépin, Roberto Aloisio, Luis A. Anchordoqui, Austin Cummings, John F. Krizmanic | Summary: High to ultrahigh energy neutrino detectors can uniquely probe the properties of dark matter $chi$ by searching for the secondary products produced through annihilation and/or decay processes. We evaluate the sensitivities to […]
Kavli Affiliate: David Gross | First 5 Authors: Tim Fuchs, David Gross, Peter Jung, Felix Krahmer, Richard Kueng | Summary: Low-rank matrix recovery problems arise naturally as mathematical formulations of various inverse problems, such as matrix completion, blind deconvolution, and phase retrieval. Over the last two decades, a number of works have rigorously analyzed the […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ziggy Pleunis, Deborah C. Good, Victoria M. Kaspi, Ryan Mckinven, Scott M. Ransom | Summary: We present a synthesis of fast radio burst (FRB) morphology (the change in flux as a function of time and frequency) as detected in the 400-800 MHz octave by the FRB […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Masoud Rafiei-Ravandi, Kendrick M. Smith, Dongzi Li, Kiyoshi W. Masui, Alexander Josephy | Summary: The CHIME/FRB Project has recently released its first catalog of fast radio bursts (FRBs), containing 492 unique sources. We present results from angular cross-correlations of CHIME/FRB sources with galaxy catalogs. We find […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: The CHIME/FRB Collaboration, :, Mandana Amiri, Bridget C. Andersen, Kevin Bandura | Summary: We present a catalog of 536 fast radio bursts (FRBs) detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project between 400 and 800 MHz from 2018 July 25 to […]
