Path-Dependent Supercooling of the $^3$He Superfluid A-B transition
Kavli Affiliate: Jeevak Parpia | First 5 Authors: Dmytro Lotnyk, Anna Eyal, Nikolay Zhelev, Abhilash Sebastian, Yefan Tian | Summary: We examine the discontinuous first-order superfluid $^3$He A to B transition in the vicinity of the polycritical point (2.232 mK and 21.22 bar). We find path-dependent transitions: cooling at fixed pressure yields a well defined […]

X-ray flares from the stellar tidal disruption by a candidate supermassive black hole binary
Kavli Affiliate: Fukun Liu | First 5 Authors: Xinwen Shu, Wenjie Zhang, Shuo Li, Ning Jiang, Liming Dou | Summary: Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches, X-ray follow-up observations have produced no or […]

Gravitational wave constraints on the primordial black hole dominated early universe
Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Chunshan Lin, Misao Sasaki, , | Summary: We calculate the gravitational waves (GWs) induced by the density fluctuations due to inhomogeneous distribution of primordial black holes (PBHs) in the case where PBHs eventually dominate and reheat the universe by Hawking evaporation. The initial PBH density […]

Elliptical accretion disk as a model for tidal disruption events
Kavli Affiliate: Fukun Liu | First 5 Authors: Fukun Liu, Chunyang Cao, Marek A. Abramowicz, Maciek Wielgus, Rong Cao | Summary: Elliptical accretion disk models for tidal disruption events (TDEs) have been recently proposed and independently developed by two groups. Although these two models are characterized by a similar geometry, their physical properties differ considerably. […]

GPI 2.0: Upgrades to the IFS including new spectral modes
Kavli Affiliate: Arlene Aleman | First 5 Authors: Mary Anne Limbach, Jeffrey Chilcote, Quinn Konopacky, Robert De Rosa, Randall Hamper | Summary: The Gemini Planet Imager (GPI) is a high-contrast imaging instrument designed to directly image and characterize exoplanets. GPI is currently undergoing several upgrades to improve performance. In this paper, we discuss the upgrades […]

Origin of the in-orbit instrumental background of the Hard X-ray Imager onboard Hitomi
Kavli Affiliate: Shinichiro Takeda | First 5 Authors: Kouichi Hagino, Hirokazu Odaka, Goro Sato, Tamotsu Sato, Hiromasa Suzuki | Summary: Understanding and reducing the in-orbit instrumental backgrounds are essential to achieving high sensitivity in hard X-ray astronomical observations. The observational data of the Hard X-ray Imager (HXI) on board the Hitomi satellite provides useful information […]

Effect on Dark Matter Exclusion Limits from New Silicon Photoelectric Absorption Measurements
Kavli Affiliate: Blas Cabrera | First 5 Authors: Belina von Krosigk, Matthew J. Wilson, Chris Stanford, Blas Cabrera, Robert Calkins | Summary: Recent breakthroughs in cryogenic silicon detector technology allow for the observation of single electron-hole pairs released via particle interactions within the target material. This implies sensitivity to energy depositions as low as the […]
