Ly$α$ emission in galaxies at $zsimeq5-6$: new insight from JWST into the statistical distributions of Ly$α$ properties at the end of reionization

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Mengtao Tang, Daniel P. Stark, Richard S. Ellis, Fengwu Sun, Michael Topping | Summary: JWST has recently sparked a new era of Ly$alpha$ spectroscopy, delivering the first measurements of the Ly$alpha$ escape fraction and velocity profile in typical galaxies at $zsimeq6-10$. These observations offer new prospects for […]

[O IV] and [Ne V]-weak AGNs Hidden by Compton-thick Material in Late Mergers

Kavli Affiliate: Claudio Ricci | First 5 Authors: Satoshi Yamada, Yoshihiro Ueda, Taiki Kawamuro, Claudio Ricci, Yoshiki Toba | Summary: We study "buried" active galactic nuclei (AGNs) almost fully covered by circumnuclear material in ultra-/luminous infrared galaxies (U/LIRGs), which show weak ionized lines from narrow line regions. Employing an indicator of [O IV] 25.89-um or […]

GenEFT: Understanding Statics and Dynamics of Model Generalization via Effective Theory

Kavli Affiliate: Max Tegmark | First 5 Authors: David D. Baek, Ziming Liu, Max Tegmark, , | Summary: We present GenEFT: an effective theory framework for shedding light on the statics and dynamics of neural network generalization, and illustrate it with graph learning examples. We first investigate the generalization phase transition as data size increases, […]

Quantum Melting of a Disordered Wigner Solid

Kavli Affiliate: Feng Wang | First 5 Authors: Ziyu Xiang, Hongyuan Li, Jianghan Xiao, Mit H. Naik, Zhehao Ge | Summary: The behavior of two-dimensional electron gas (2DEG) in extreme coupling limits are reasonably well-understood, but our understanding of intermediate region remains limited. Strongly interacting electrons crystalize into a solid phase known as the Wigner […]

Robust inference of the Galactic centre gamma-ray excess spatial properties

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Deheng Song, Christopher Eckner, Chris Gordon, Francesca Calore, Oscar Macias | Summary: The gamma-ray Fermi-LAT Galactic centre excess (GCE) has puzzled scientists for over 15 years. Despite ongoing debates about its properties, and especially its spatial distribution, its nature remains elusive. We scrutinize how the estimated spatial […]
