JWST CEERS & JADES Active Galaxies at z = 4-7 Violate the Local $M_bullet-M_star$ Relation at $>3σ$: Implications for Low-Mass Black Holes and Seeding Models

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Fabio Pacucci, Bao Nguyen, Stefano Carniani, Roberto Maiolino, Xiaohui Fan | Summary: JWST is revolutionizing our understanding of the high-z Universe by expanding the black hole horizon, looking farther and to smaller masses, and revealing the stellar light of their hosts. New detections of high-z systems offer […]

TOI-332 b: a super dense Neptune found deep within the Neptunian desert

Posted by klaurent August 23, 2023September 7, 2023MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Ares Osborn, David J. Armstrong, Jorge Fernández Fernández, Henrik Knierim, Vardan Adibekyan | Summary: To date, thousands of planets have been discovered, but there are regions of the orbital parameter space that are still bare. An example is the short period and intermediate mass/radius space known as […]

Reconstruction procedure of the Fluorescence detector Array of Single-pixel Telescopes (FAST)

Posted by klaurent August 23, 2023September 7, 2023Chicago

Kavli Affiliate: Paolo Privitera | First 5 Authors: Fraser Bradfield, Justin Albury, Jose Bellido, Ladislav Chytka, John Farmer | Summary: The Fluorescence detector Array of Single-pixel Telescopes (FAST) is one of several proposed designs for a next-generation cosmic-ray detector. Such detectors will require enormous collecting areas whilst also needing to remain cost-efficient. To meet these […]

Detecting ultra-high-energy cosmic rays with prototypes of the Fluorescence detector Array of Single-pixel Telescopes (FAST) in both hemispheres

Posted by klaurent August 23, 2023September 7, 2023Chicago

Kavli Affiliate: Paolo Privitera | First 5 Authors: Shunsuke Sakurai, Justin Albury, Jose Bellido, Fraser Bradfield, Ladislav Chytka | Summary: Ultra-high energy cosmic rays (UHECRs), whose energy are beyond $10^{18}~mathrm{eV}$, are the most energetic particles we have ever detected. The latest results seem to indicate a heavier composition at the highest energies, complicating the search […]

OFVL-MS: Once for Visual Localization across Multiple Indoor Scenes

Posted by klaurent August 23, 2023September 7, 2023Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Tao Xie, Kun Dai, Siyi Lu, Ke Wang, Zhiqiang Jiang | Summary: In this work, we seek to predict camera poses across scenes with a multi-task learning manner, where we view the localization of each scene as a new task. We propose OFVL-MS, a unified framework that […]

The Accretion History of EX Lup: A Century of Bursts, Outbursts, and Quiescence

Posted by klaurent August 23, 2023September 7, 2023Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Mu-Tian Wang, Gregory J. Herczeg, Hui-Gen Liu, Min Fang, Doug Johnstone | Summary: EX Lup is the archetype for the class of young stars that undergoes repeated accretion outbursts of $sim 5$ mag at optical wavelengths and that last for months. Despite extensive monitoring that dates […]

Modeling Dust Production, Growth, and Destruction in Reionization-Era Galaxies with the CROC Simulations II: Predicting the Dust Content of High-Redshift Galaxies

Posted by klaurent August 22, 2023September 7, 2023Chicago

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Clarke J. Esmerian, Nickolay Y. Gnedin, , , | Summary: We model the interstellar dust content of the reionization era with a suite of cosmological, fluid-dynamical simulations of galaxies with stellar masses ranging from $sim 10^5 – 10^9 M_{odot}$ in the first $1.2$ billion years of […]

A Measurement of Gravitational Lensing of the Cosmic Microwave Background Using SPT-3G 2018 Data

Posted by August 22, 2023Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: Z. Pan, F. Bianchini, W. L. K. Wu, P. A. R. Ade, Z. Ahmed | Summary: We present a measurement of gravitational lensing over 1500 deg$^2$ of the Southern sky using SPT-3G temperature data at 95 and 150 GHz taken in 2018. The lensing amplitude relative to […]
