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 […]

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 […]
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 […]

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 […]

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 […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Kasper E. Heintz, Jake S. Bennett, Pascal A. Oesch, Albert Sneppen, Douglas Rennehan | Summary: Galaxy clusters are the most massive, gravitationally-bound structures in the Universe, emerging through hierarchical structure formation of large-scale dark matter and baryon overdensities. Early galaxy “proto-clusters” are believed to be important physical […]
