Damped Ly-alpha Absorbers in Star-forming Galaxies at z < 0.15 Detected with the Hubble Space Telescope and Implications for Galaxy Evolution

Posted by klaurent Chicago

Kavli Affiliate: Donald G. York | First 5 Authors: Varsha P. Kulkarni, David V. Bowen, Lorrie A. Straka, Donald G. York, Neeraj Gupta | Summary: We report {it HST} COS spectroscopy of 10 quasars with foreground star-forming galaxies at 0.02$<$$z$$<$ 0.14 within impact parameters of $sim$1-7 kpc. We detect damped/sub-damped Ly$alpha$ absorption in 100$%$ of […]

Recent advances in branching problems of representations

Posted by klaurent Tokyo

Kavli Affiliate: Toshiyuki Kobayashi | Summary:How does an irreducible representation of a group behave when restricted to a subgroup? This is part of branching problems, which are one of the fundamental problems in representation theory, and also interact naturally with other fields of mathematics. This expository paper is an up-to-date account on some new directions […]

Priors on red galaxy stochasticity from hybrid effective field theory

Posted by klaurent Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Nickolas Kokron, Joseph DeRose, Shi-Fan Chen, Martin White, Risa H. Wechsler | Summary: We investigate the stochastic properties of typical red galaxy samples in a controlled numerical environment. We use Halo Occupation Distribution (HOD) modelling to create mock realizations of three separate bright red galaxy samples […]

AutoDrop: Training Deep Learning Models with Automatic Learning Rate Drop

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Yunfei Teng, Jing Wang, Anna Choromanska, , | Summary: Modern deep learning (DL) architectures are trained using variants of the SGD algorithm that is run with a $textit{manually}$ defined learning rate schedule, i.e., the learning rate is dropped at the pre-defined epochs, typically when the training loss […]

Weighing the Milky Way and Andromeda with Artificial Intelligence

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Pablo Villanueva-Domingo, Francisco Villaescusa-Navarro, Shy Genel, Daniel Anglés-Alcázar, Lars Hernquist | Summary: We present new constraints on the masses of the halos hosting the Milky Way and Andromeda galaxies derived using graph neural networks. Our models, trained on thousands of state-of-the-art hydrodynamic simulations of the CAMELS […]

Plastic Laminate Antireflective Coatings for Millimeter-wave Optics in BICEP Array

Posted by klaurent Stanford

Kavli Affiliate: Keith Thompson | Summary:The BICEP/Keck series of experiments target the Cosmic Microwave Background at degree-scale resolution from the South Pole. Over the next few years, the "Stage-3" BICEP Array (BA) telescope will improve the program’s frequency coverage and sensitivity to primordial B-mode polarization by an order of magnitude. The first receiver in the […]
