A NICER View of the Nearest and Brightest Millisecond Pulsar: PSR J0437$unicode{x2013}$4715

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Devarshi Choudhury, Tuomo Salmi, Serena Vinciguerra, Thomas E. Riley, Yves Kini | 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 […]

Investigating the interplay between AGN coronal properties and hard X-ray variability with NuSTAR

Kavli Affiliate: Claudio Ricci | First 5 Authors: Roberto Serafinelli, Alessandra De Rosa, Alessia Tortosa, Luigi Stella, Fausto Vagnetti | Summary: Active galactic nuclei (AGN) are extremely variable in the X-ray band down to very short time scales. However, the driver of the X-ray variability is still poorly understood. Previous results suggest that the hot […]

TVR-Ranking: A Dataset for Ranked Video Moment Retrieval with Imprecise Queries

Kavli Affiliate: Jing Wang | First 5 Authors: Renjie Liang, Li Li, Chongzhi Zhang, Jing Wang, Xizhou Zhu | Summary: In this paper, we propose the task of textit{Ranked Video Moment Retrieval} (RVMR) to locate a ranked list of matching moments from a collection of videos, through queries in natural language. Although a few related […]

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

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Monica Valluri, Parker Fagrelius, Sergey. E. Koposov, Ting S. Li, Oleg Y. Gnedin | Summary: We present ~ 126 new spectroscopically identified members of the GD-1 tidal stream obtained with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence of a “cocoon” which is […]
