A NICER View of the Nearest and Brightest Millisecond Pulsar: PSR J0437$unicodex2013$4715

Posted by klaurent July 9, 2024MIT

Kavli Affiliate: Ronald Remillard | Summary:We report Bayesian inference of the mass, radius and hot X-ray emitting region properties – using data from the Neutron Star Interior Composition ExploreR (NICER) – for the brightest rotation-powered millisecond X-ray pulsar PSR J0437$unicodex2013$4715. Our modeling is conditional on informative tight priors on mass, distance and binary inclination obtained […]

The quantum metric of electrons with spin-momentum locking

Posted by klaurent July 9, 2024Delft

Kavli Affiliate: Andrea D. Caviglia | Summary:Quantum materials are characterized by electromagnetic responses intrinsically linked to the geometry and topology of electronic wavefunctions, encoded in the quantum metric and Berry curvature. Whereas Berry curvature-mediated transport effects have been identified in several magnetic and nonmagnetic systems, quantum metric-induced transport phenomena remain limited to topological antiferromagnets. Here […]

Rotational Properties of Inverted Hybrid Stars

Posted by dbos July 8, 2024Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Rodrigo Negreiros, Chen Zhang, Renxin Xu, , | Summary: We study the rotational properties of inverted hybrid stars (also termed cross stars), which have been recently proposed as a possible new class of compact stars characterized by an outer layer of quark matter and a core of […]

Stochastic Traveling Salesperson Problem with Neighborhoods for Object Detection

Posted by dbos July 8, 2024July 22, 2024UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Minghan Wei, Volkan Isler, , | Summary: We introduce a new route-finding problem which considers perception and travel costs simultaneously. Specifically, we consider the problem of finding the shortest tour such that all objects of interest can be detected successfully. To represent a viable detection […]

GD-1 Stellar Stream and Cocoon in the DESI Early Data Release

Posted by dbos July 8, 2024Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Monica Valluri, Parker Fagrelius, Sergey. E. Koposov, Ting S. Li, Oleg Y. Gnedin | Summary: We present 115 new spectroscopically identified members of the GD-1 tidal stream observed with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence of a “cocoon” which is a […]
