Highly Excited Electron Cyclotron for QCD Axion and Dark-Photon Detection

Kavli Affiliate: Peter W. Graham | First 5 Authors: Xing Fan, Gerald Gabrielse, Peter W. Graham, Harikrishnan Ramani, Samuel S. Y. Wong | Summary: We propose using highly excited cyclotron states of a trapped electron to detect meV axion and dark photon dark matter, marking a significant improvement over our previous proposal and demonstration [Phys. […]

Mind the kinematics simulation of planet-disk interactions: time evolution and numerical resolution

Kavli Affiliate: Ruobing Dong | First 5 Authors: Kan Chen, Ruobing Dong, , , | Summary: Planet-disk interactions can produce kinematic signatures in protoplanetary disks. While recent observations have detected non-Keplerian gas motions in disks, their origins are still being debated. To explore this, we conduct 3D hydrodynamic simulations using the code FARGO3D to study […]

A long spin period for a sub-Neptune-mass exoplanet

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Ellen M. Price, Juliette Becker, Zoë L. de Beurs, Leslie A. Rogers, Andrew Vanderburg | Summary: HIP 41378 f is a sub-Neptune exoplanet with an anomalously low density. Its long orbital period and deep transit make it an ideal candidate for detecting oblateness photometrically. We present a […]

Age-dating early quiescent galaxies: high star-formation efficiency, but consistent with direct, higher-redshift observations

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Crispin Turner, Sandro Tacchella, Francesco D’Eugenio, Stefano Carniani, Mirko Curti | Summary: We present a detailed analysis of JWST/NIRSpec and NIRCam observations of ZF-UDS-7329, a massive, quiescent galaxy at redshift $z=3.2$, which has been put forward to challenge cosmology and galaxy formation physics. Our study extends previous […]

Tomographic constraint on anisotropic cosmic birefringence

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, , , , | Summary: We for the first time constrain anisotropic cosmic birefringence generated at reionization using Planck PR4 polarization data. Several recent analyses of WMAP and Planck polarization data have found a tantalizing hint of isotropic cosmic birefringence. Ongoing and future CMB experiments […]

Classification of radio backgrounds at cosmic dawn and 21-cm signal confirmation using neural networks

Kavli Affiliate: George Efstathiou | First 5 Authors: Sudipta Sikder, Anastasia Fialkov, Rennan Barkana, , | Summary: Several ongoing and upcoming radio telescopes aim to detect either the global 21-cm signal or the 21-cm power spectrum. The extragalactic radio background, as detected by ARCADE-2 and LWA-1, suggests a strong radio background from cosmic dawn, which […]

Gravitational Particle Production of Scalars: Analytic and Numerical Approaches Including Early Reheating

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Leah Jenks, Edward W. Kolb, Keyer Thyme, , | Summary: Cosmological gravitational particle production (GPP) is a generic mechanism by which particles are produced during the inflationary epoch. In this work we consider the GPP of massive scalars in an effort to fully understand the spectrum […]

Connecting Lyman-$α$ and ionizing photon escape in the Sunburst Arc

Kavli Affiliate: Michael D. Gladders | First 5 Authors: M. Riley Owens, Keunho J. Kim, Matthew B. Bayliss, T. Emil Rivera-Thorsen, Keren Sharon | Summary: We investigate the Lyman-$alpha$ (Ly$alpha$) and Lyman continuum (LyC) properties of the Sunburst Arc, a $z=2.37$ gravitationally lensed galaxy with a multiply-imaged, compact region leaking LyC and a triple-peaked Ly$alpha$ […]

A long-duration superflare on the K giant HD 251108

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Hans Moritz Günther, Dheeraj Pasham, Alexander Binks, Stefan Czesla, Teruaki Enoto | Summary: Many giant stars are magnetically active, which causes rotational variability, chromospheric emission lines, and X-ray emission. Large outbursts in these emission features can set limits on the magnetic field strength and thus constrain the […]

Textless Streaming Speech-to-Speech Translation using Semantic Speech Tokens

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Jinzheng Zhao, Niko Moritz, Egor Lakomkin, Ruiming Xie, Zhiping Xiu | Summary: Cascaded speech-to-speech translation systems often suffer from the error accumulation problem and high latency, which is a result of cascaded modules whose inference delays accumulate. In this paper, we propose a transducer-based speech translation model […]
