Light Dark Matter Constraints from SuperCDMS HVeV Detectors Operated Underground with an Anticoincidence Event Selection

Posted by dbos Stanford

Kavli Affiliate: D. B. Macfarlane | First 5 Authors: SuperCDMS Collaboration, M. F. Albakry, I. Alkhatib, D. Alonso-González, D. W. P. Amaral | Summary: This article presents constraints on dark-matter-electron interactions obtained from the first underground data-taking campaign with multiple SuperCDMS HVeV detectors operated in the same housing. An exposure of 7.63 g-days is used […]

Circumnuclear Dust in Luminous Early-Type Galaxies — I. Sample Properties and Stellar Luminosity Models

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jared R. Davidson, Benjamin D. Boizelle, Jonelle L. Walsh, Aaron J. Barth, Emma Rasmussen | Summary: Dusty circumnuclear disks (CNDs) in luminous early-type galaxies (ETGs) show regular, dynamically cold molecular gas kinematics. For a growing number of ETGs, Atacama Large Millimeter/sub-millimeter Array (ALMA) CO imaging and […]

Rising from the ashes: evidence of old stellar populations and rejuvenation events in the very early Universe

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Callum Witten, William McClymont, Nicolas Laporte, Guido Roberts-Borsani, Debora Sijacki | Summary: While JWST has observed galaxies assembling as early as $zsim14$, evidence of galaxies with significant old stellar populations in the Epoch of Reionisation (EoR) — the descendants of these earliest galaxies — are few and […]

The discovery of a nearby 421~s transient with CHIME/FRB/Pulsar

Posted by dbos MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Fengqiu Adam Dong, Tracy Clarke, Alice P. Curtin, Ajay Kumar, Ingrid Stairs | Summary: Neutron stars and white dwarfs are both dense remnants of post-main-sequence stars. Pulsars, magnetars and strongly magnetised white dwarfs have all been seen to been observed to exhibit coherent, pulsed radio emission […]

CHIME/FRB/Pulsar discovery of a nearby long period radio transient with a timing glitch

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Fengqiu Adam Dong, Fengqiu Adam Dong, , , | Summary: We present the discovery of a 421 s long period radio transient (LPT) using the CHIME telescope, CHIME J0630+25. The source is localized to RA=06:30:38.4$pm1’$ Dec=25:26:24$pm1’$ using voltage data acquired with the CHIME baseband system. A […]
