Orbital Evolution of Satellite Galaxies in Self-Interacting Dark Matter Models

Posted by klaurent Peking

Oren Slone, Fangzhou Jiang, Mariangela Lisanti, Manoj Kaplinghat, | Summary: [[{“value”:”Dark matter self interactions can leave distinctive signatures on the properties of satellite galaxies around Milky Way–like hosts through their impact on tidal stripping, ram pressure, and gravothermal collapse. We delineate the regions of self-interacting dark matter parameter space — specified by interaction cross section […]

GLASS: Geometric Latent Augmentation for Shape Spaces

Posted by klaurent UCSB

Kavli Affiliate: Matthew Fisher | First 5 Authors: Sanjeev Muralikrishnan, Siddhartha Chaudhuri, Noam Aigerman, Vladimir Kim, Matthew Fisher | Summary: We investigate the problem of training generative models on a very sparse collection of 3D models. We use geometrically motivated energies to augment and thus boost a sparse collection of example (training) models. We analyze […]

Forecasting racial dynamics at the neighborhood scale using Density-functional Fluctuation Theory

Posted by klaurent Cornell

Kavli Affiliate: Itai Cohen | First 5 Authors: Yunus A. Kinkhabwala, Boris Barron, Matthew Hall, Tomas A. Arias, Itai Cohen | Summary: Racial residential segregation is a defining and enduring feature of U.S. society, shaping inter-group relations, racial disparities in income and health, and access to high-quality public goods and services. The design of policies […]

A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). IV. Rapidly Growing (Super-)Massive Black Holes in Extremely Radio-Loud Galaxies

Posted by klaurent Peking

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Ichikawa, Takuji Yamashita, Yoshiki Toba, Tohru Nagao, Kohei Inayoshi | Summary: We present the optical and infrared properties of 39 extremely radio-loud galaxies discovered by cross-matching the Subaru/Hyper Suprime-Cam (HSC) deep optical imaging survey and VLA/FIRST 1.4 GHz radio survey. The recent Subaru/HSC strategic survey revealed […]
