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: Andrea D. Caviglia | First 5 Authors: Giacomo Sala, Maria Teresa Mercaldo, Klevis Domi, Stefano Gariglio, Mario Cuoco | Summary: Quantum materials are characterized by electromagnetic responses intrinsically linked to the geometry and topology of the electronic wavefunctions. These properties are encoded in the quantum metric and Berry curvature. While Berry curvature-mediated transport […]

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: 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 […]
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 […]
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 […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: R. P. Day, K. Yamakawa, L. Pritchard Cairns, J. Singleton, Monica Allen | Summary: We report on the thermodynamic and transport properties of the rare-earth Zintl compound Eu$_5$Sn$_2$As$_6$, which orders as a canted antiferromagnetic magnetic semiconductor at 10.3~K. The system also displays a complex cascade of […]
