Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, P. Ahlburg | Summary: A search for the flavor-changing neutral-current decay $B^{+}to K^{+}nubar{nu}$ is performed at the Belle II experiment at the SuperKEKB asymmetric energy electron-positron collider. The results are based on a data sample corresponding to an […]
Kavli Affiliate: Sarah E. Church | First 5 Authors: Jaime E. Pineda, Anika Schmiedeke, Paola Caselli, Steven W. Stahler, David T. Frayer | Summary: Dense cores are the final place where turbulence is dissipated. It has been proposed from theoretical arguments that the non-thermal velocity dispersion should be narrower both for molecular ions (compared to […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Bharat K. Gehlot, Daniel C. Jacobs, Judd D. Bowman, Nivedita Mahesh, Steven G. Murray | Summary: Precision calibration poses challenges to experiments probing the redshifted 21-cm signal of neutral hydrogen from the Cosmic Dawn and Epoch of Reionization (z~30-6). In both interferometric and global signal experiments, systematic […]
Kavli Affiliate: Alan M. Levine | First 5 Authors: Brett Christopher Addison, Emil Knudstrup, Ian Wong, Guillaume Hebrard, Patrick Dorval | Summary: We present the discovery of a highly irradiated and moderately inflated ultra-hot Jupiter, TOI-1431b/MASCARA-5b (HD 201033b), first detected by NASA’s Transiting Exoplanet Survey Satellite mission (TESS) and the Multi-site All-Sky CAmeRA (MASCARA). The […]
Kavli Affiliate: Mark J. Bowick | First 5 Authors: Zhitao Chen, Duanduan Wan, Mark J. Bowick, , | Summary: Very thin elastic sheets, even at zero temperature, exhibit nonlinear elastic response by virtue of their dominant bending modes. Their behavior is even richer at finite temperature. Here we use molecular dynamics (MD) to study the […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Xiangyun Long, Hua Feng, Hong Li, Jiahuan Zhu, Qiong Wu | Summary: We report follow-up observations of the Crab nebula with the PolarLight X-ray polarimeter, which revealed a possible variation in polarization associated with a pulsar glitch in 2019. The new observations confirm that the polarization has […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Oliver Newton, Noam I. Libeskind, Alexander Knebe, Miguel A. Sánchez-Conde, Jenny G. Sorce | Summary: The Local Group is a unique environment in which to study the astrophysics of galaxy formation. The proximity of the Milky Way and M31 enhances the frequency of interactions of the low-mass […]
Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: André Melo, Valla Fatemi, Anton R. Akhmerov, , | Summary: The multi-terminal Josephson effect allows DC supercurrent to flow at finite commensurate voltages. Existing proposals to realize this effect rely on nonlocal Andreev processes in superconductor-normal-superconductor junctions. However, this approach requires precise control over microscopic states […]
Kavli Affiliate: Wei Gao | First 5 Authors: Ren Yang, Radu Timofte, Jing Liu, Yi Xu, Xinjian Zhang | Summary: This paper reviews the first NTIRE challenge on quality enhancement of compressed video, with a focus on the proposed methods and results. In this challenge, the new Large-scale Diverse Video (LDV) dataset is employed. The […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Wei Yan, Ryan C. Hickox, Chien-Ting J. Chen, Claudio Ricci, Alberto Masini | Summary: In active galactic nuclei (AGN), fluorescent Fe K$alpha$ (iron) line emission is generally interpreted as originating from obscuring material around a supermassive black hole (SMBH) on the scale of a few parsecs (pc).
