The Ophiuchus DIsk Survey Employing ALMA (ODISEA): Complete Size Distributions for the 100 Brightest Disks Across Multiplicity and SED Classes

Posted by klaurent Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Anuroop Dasgupta, Lucas A. Cieza, Camilo I. Gonzalez Ruilova, Trisha Bhowmik, Ms. Prachi Chavan | Summary: The size of a protoplanetary disk is a fundamental property, yet most remain unresolved, even in nearby star-forming regions (d $sim$ 140-200 pc). We present the complete continuum size distribution […]

A Disintegrating Rocky Planet with Prominent Comet-like Tails Around a Bright Star

Posted by klaurent MIT

Kavli Affiliate: George R. Ricker | First 5 Authors: Marc Hon, Saul Rappaport, Avi Shporer, Andrew Vanderburg, Karen A. Collins | Summary: We report the discovery of BD+05$,$4868$,$Ab, a transiting exoplanet orbiting a bright ($V=10.16$) K-dwarf (TIC 466376085) with a period of 1.27 days. Observations from NASA’s Transiting Exoplanet Survey Satellite (TESS) reveal variable transit […]

Time-resolved Hubble Space Telescope UV observations of an X-ray quasi-periodic eruption source

Posted by klaurent MIT

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Thomas Wevers, Muryel Guolo, Sean Lockwood, Andrew Mummery, Dheeraj R. Pasham | Summary: X-ray quasi-periodic eruptions (QPEs) are a novel mode of variability in nearby galactic nuclei whose origin remains unknown. Their multi-wavelength properties are poorly constrained, as studies have focused almost entirely on the X-ray […]

Comprehensive Bayesian Exploration of Froggatt-Nielsen Mechanism

Posted by klaurent Tokyo

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Satoshi Shirai, Keiichi Watanabe, , | Summary: The Froggatt-Nielsen (FN) mechanism successfully explains the hierarchical structure of fermion Yukawa couplings by introducing a U(1) flavor symmetry with distinct charge assignments for different fermion generations. While some FN charge assignments have been proposed, their evaluation has […]

Development of a bipolar 50 V output digital-to-analog converter system for ion-shuttling operations

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: T. Oshio, R. Nishimoto, T. Higuchi, K. Hayasaka, K. Koike | Summary: The quantum charge-coupled device (QCCD) is one of the notable architectures to achieve large-scale trapped-ion quantum computers. To realize QCCD architecture, ions must be transported quickly while minimizing motional excitation. High-voltage sources are necessary to […]

SZ-X-ray Surface Brightness Fluctuations in the SPT-XMM clusters

Posted by klaurent Chicago

Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Charles Romero, Massimo Gaspari, Gerrit Schellenberger, Bradford A. Benson, Lindsey E. Bleem | Summary: The hot plasma in galaxy clusters, the intracluster medium (ICM), is expected to be shaped by subsonic turbulent motions, which are key for heating, cooling, and transport mechanisms. The turbulent motions contribute […]

The Higgs-Amplitude mode in the optical conductivity in the presence of a supercurrent: Gauge-invariant formulation with disorder

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Rufus Boyack, K. Levin, , | Summary: Observing the “Higgs" or amplitude mode in superconductors has been a central challenge in condensed matter physics. Moreover, arriving at a theoretical understanding of this mode and how it is accessible in, say, conductivity experiments presents an additional […]

Gravitational Waves from Metastable Cosmic Strings in Supersymmetric New Inflation Model

Posted by klaurent Tokyo

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Akifumi Chitose, Masahiro Ibe, Shunsuke Neda, Satoshi Shirai, | Summary: Recent observations by pulsar timing arrays (PTAs) indicate a potential detection of a stochastic gravitational wave (GW) background. Metastable cosmic strings have been recognized as a possible source of the observed signals. In this paper, we propose […]
