Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: 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 […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Robert A. Wittenmyer, Jake T. Clark, Trifon Trifonov, Brett C. Addison, Duncan J. Wright | Summary: The imminent launch of space telescopes designed to probe the atmospheres of exoplanets has prompted new efforts to prioritise the thousands of transiting planet candidates for follow-up characterisation. We report the […]
Kavli Affiliate: Sara Seager | First 5 Authors: William Bains, Oliver Shorttle, Sukrit Ranjan, Paul B. Rimmer, Janusz J. Petkowski | Summary: The initial reports of the presence of phosphine in the cloud decks of Venus has led to the suggestion that volcanism was the source of phosphine, through volcanic phosphides ejected into the clouds. […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Sandro Tacchella, Aaron Smith, Rahul Kannan, Federico Marinacci, Lars Hernquist | Summary: The nebular recombination line H$alpha$ is widely used as a star-formation rate (SFR) indicator in the local and high-redshift Universe. We present a detailed H$alpha$ radiative transfer study of high-resolution isolated Milky-Way and Large Magellanic […]
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 […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Jean-Baptiste Bayle, Béatrice Bonga, Daniela Doneva, Tanja Hinderer, Archisman Ghosh | Summary: Gravitational wave science is a dynamical, fast-expanding research field founded on results, tools and methodologies drawn from different research areas and communities. Early career scientists entering this field must learn and combine knowledge and techniques […]
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 […]
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 […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Ronny Frumkin, Yonit Hochberg, Eric Kuflik, Hitoshi Murayama, | Summary: We propose a new thermal dark matter candidate whose abundance is determined by the freezeout of inverse decays. The relic abundance depends parametrically only on a decay width, while matching the observed value requires that the coupling […]
Kavli Affiliate: C. L. Kuo | First 5 Authors: A. Schillaci, P. A. R. Ade, Z. Ahmed, M. Amiri, D. Barkats | Summary: The BICEP/Keck Collaboration is currently leading the quest to the highest sensitivity measurements of the polarized CMB anisotropies on degree scale with a series of cryogenic telescopes, of which BICEP Array is […]
