TOI-1431b/MASCARA-5b: A Highly Irradiated Ultra-Hot Jupiter Orbiting One of the Hottest & Brightest Known Exoplanet Host Stars

Posted by klaurent April 25, 2021MIT

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 […]

Spontaneous tilt of single-clamped thermal elastic sheets

Posted by klaurent April 23, 2021UCSB

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 […]

X-ray polarimetry of the Crab nebula with PolarLight: polarization recovery after the glitch and a secular position angle variation

Posted by klaurent April 23, 2021Peking

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 […]

Hermeian haloes: Field haloes that interacted with both the Milky Way and M31

Posted by klaurent April 22, 2021MIT

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 […]

Multiplet supercurrent in Josephson tunneling circuits

Posted by klaurent April 22, 2021Delft

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 […]

NTIRE 2021 Challenge on Quality Enhancement of Compressed Video: Methods and Results

Posted by April 21, 2021Caltech

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 […]

Chandra Observations of Excess Fe K$α$ Line Emission in Galaxies with High Star Formation Rates: X-ray Reflection on Galaxy Scales?

Posted by klaurent Peking

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). […]

Non-perturbative methods for false vacuum decay

Posted by klaurent April 21, 2021Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Djuna Croon, Eleanor Hall, Hitoshi Murayama, , | Summary: We propose a simple non-perturbative formalism for false vacuum decay using functional methods. We introduce the quasi-stationary effective action, a bounce action that non-perturbatively incorporates radiative corrections and is robust to strong couplings. The quasi-stationary effective action obeys […]

Chiral Anomaly Trapped in Weyl Metals: Nonequilibrium Valley Polarization at Zero Magnetic Field

Posted by klaurent April 20, 2021Delft

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Pablo M. Perez-Piskunow, Nicandro Bovenzi, Anton R. Akhmerov, Maxim Breitkreiz, | Summary: In Weyl semimetals the application of parallel electric and magnetic fields leads to valley polarization — an occupation disbalance of valleys of opposite chirality — a direct consequence of the chiral anomaly. In this […]

Distinct chemistries explain decoupling of slip and wettability in atomically smooth aqueous interfaces

Posted by April 20, 2021Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Anthony R. Poggioli, David T. Limmer, , , | Summary: Despite essentially identical crystallography and equilibrium structuring of water, nanoscopic channels composed of hexagonal boron nitride and graphite exhibit an order-of-magnitude difference in fluid slip. We investigate this difference using molecular dynamics simulations, demonstrating that its […]
