The Tidal Disruption Event AT2021ehb: Evidence of Relativistic Disk Reflection, and Rapid Evolution of the Disk-Corona System

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 […]

Temperature Dependence of the Emission Spectrum of GaN Defect Single-Photon Emitters

Kavli Affiliate: Farhan Rana | First 5 Authors: Yifei Geng, Jialun Luo, Len van Deurzen, Huili, Xing | Summary: Single-photon emitters (SPEs) in technologically mature wide bandgap semiconductors are attractive for realizing integrated platforms for quantum applications. We investigate single-photon emitters in GaN. GaN hosts bright and stable single-photon emitters in the 600 nm to […]

Targeted cortical stimulation reveals principles of cortical contextual interactions

Kavli Affiliate: Kenneth Miller | Authors: Shen Wang, Agostina Palmigiano, Kenneth D Miller and Stephen David Van Hooser | Summary: Cross-orientation suppression is a classic form of contextual normalization in visual cortex, yet the degree to which cortical circuits participate in the normalization computation is unclear. We visualized orientation maps of individual ferrets, and provided […]

The complex dynamical past and future of double eclipsing binary CzeV343: misaligned orbits and period resonance

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) […]

X-ray Halos around Massive Galaxies: Data and Theory

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 […]

A non-linear solution to the $S_8$ tension?

Kavli Affiliate: George Efstathiou | First 5 Authors: Alexandra Amon, George Efstathiou, , , | Summary: Weak galaxy lensing surveys have consistently reported a lower amplitude for the matter fluctuation spectrum, as measured by the $S_8$ parameter, than expected in the $Lambda{rm CDM}$ cosmology favoured by $Planck$. However, the expansion history follows the predictions of […]

Bridging quantum many-body scar and quantum integrability in Ising chains with transverse and longitudinal fields

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 […]
