$^42$Ar Production and Injection to a Liquid Argon Environment for Background Mitigation Studies

Posted by klaurent MIT

Kavli Affiliate: Moritz Guenther| First 5 Authors: Mario Schwarz, Mario Schwarz, , , | Summary:Atmosphere-sourced argon contains traces of $^42$Ar, whose $β^-$-decaying progeny $^42$K represents a significant intrinsic background for rare-event experiments using liquid argon (LAr) as detector or shielding medium. Understanding and mitigating this background is crucial for current and future large-scale detectors in […]

Preparation and evaluation of alexandrite, forsterite, and topaz substrates for the epitaxial growth of rutile oxides

Posted by klaurent Cornell

Kavli Affiliate: Darrell Schlom| First 5 Authors: Monique Kubovsky, Monique Kubovsky, , , | Summary:Metal-insulator transitions and superconductivity in rutile-structured oxides hold promise for advanced electronic applications, yet their thin film synthesis is severely hindered by limited substrate options. Here, we present three single- crystalline substrates, BeAl2O4, Mg2SiO4, and Al2SiO4(F,OH)2, prepared via optimized thermal and […]

How Low Can You Go: Constraining the Effects of Catalog Incompleteness on Dark Siren Cosmology

Posted by klaurent Chicago

Kavli Affiliate: Daniel Holz | Summary:Gravitational waves (GWs) serve as standard sirens by directly encoding the luminosity distance to their source. When the host galaxy redshift is known, for example, through observation of an electromagnetic (EM) counterpart, GW detections can provide an independent measurement of the Hubble constant, $H_0$. However, even in the absence of […]

The Pre-Outburst Properties of the FU Ori Object HBC 722

Posted by klaurent Peking

Kavli Affiliate: Gregory Herczeg | Summary:FU Ori outbursts are thought to play an important role in stellar assembly and the evolution of protoplanetary disks. However, the progenitor young stellar objects are largely uncharacterized. We obtained a low-resolution optical spectrum of HBC 722 before its FU Ori outburst as part of a survey of young stellar […]

The AGORA High-resolution Galaxy Simulations Comparison Project. X: Formation and Evolution of Galaxies at the High-redshift Frontier

Posted by klaurent Stanford

Kavli Affiliate: Tom Abel | Summary:Recent observations from JWST have revealed unexpectedly luminous galaxies, exhibiting stellar masses and luminosities significantly higher than predicted by theoretical models at Cosmic Dawn. In this study, we present a suite of cosmological zoom-in simulations targeting high-redshift ($z geq 10$) galaxies with dark matter halo masses in the range $10^10 […]
