Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Yuhan Yao, Wenbin Lu, Muryel Guolo, Dheeraj R. Pasham, Suvi Gezari | Summary: We present X-ray, UV, optical, and radio observations of the nearby ($approx78$ Mpc) tidal disruption event (TDE) AT2021ehb/ZTF21aanxhjv during its first 430 days of evolution. AT2021ehb occurs in the nucleus of a galaxy […]
Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Ondřej Pejcha, Pavel Cagaš, Camille Landri, Michael M. Fausnaugh, Gisella De Rosa | Summary: CzeV343 (=V849 Aur) was previously identified as a candidate double eclipsing binary (2+2 quadruple), where the orbital periods of the two eclipsing binaries ($P_A approx 1.2$ days and $P_B approx 0.8$ days) […]

Kavli Affiliate: Eric Halgren | Authors: Charles W Dickey, Ilya A Verzhbinsky, Xi Jiang, Burke Q Rosen, Sophie Kajfez, Emad N Eskandar, Jorge Gonzalez-Martinez, Sydney S Cash and Eric Halgren | Summary: Hippocampal ripples index the reconstruction of spatiotemporal neuronal firing patterns essential for the consolidation of memories in the cortex during non-rapid eye movement […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Akos Bogdan, Mark Vogelsberger, , , | Summary: The presence of gaseous X-ray halos around massive galaxies is a basic prediction of all past and modern structure formation simulations. The importance of these X-ray halos is further emphasized by the fact that they retain signatures of the […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Xiaoling Cui, , , | Summary: Quantum many-body scar (QMBS) and quantum integrability(QI) have been recognized as two distinct mechanisms for the breakdown of eigenstate thermalization hypothesis(ETH) in an isolated system. In this work, we reveal a smooth route to connect these two ETH-breaking mechanisms […]

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Anna V. Payne, Katie Auchettl, Benjamin J. Shappee, Christopher S. Kochanek, Patricia T. Boyd | Summary: ASASSN-14ko is a nuclear transient at the center of the AGN ESO 253-G003 that undergoes periodic flares. Optical flares were first observed in 2014 by the All-Sky Automated Survey for […]
Kavli Affiliate: Subo Dong | First 5 Authors: Tsevi Mazeh, Simchon Faigler, Dolev Bashi, Sahar Shahaf, Niv Davidson | Summary: We have identified 2XMM J125556.57+565846.4, at a distance of 600 pc, as a binary system consisting of a normal star and a probable dormant neutron star. Optical spectra exhibit a slightly evolved F-type single star, […]
