The Curious Case of ASASSN-20hx: A Slowly-Evolving, UV and X-ray Luminous, Ambiguous Nuclear Transient

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Jason T. Hinkle, Thomas W. -S. Holoien, Benjamin. J. Shappee, Jack M. M. Neustadt, Katie Auchettl | Summary: We present observations of ASASSN-20hx, a nearby ambiguous nuclear transient (ANT) discovered in NGC 6297 by the All-Sky Automated Survey for Supernovae (ASAS-SN). We observed ASASSN-20hx from $-$30 to […]

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

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

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 […]

Precise measurement of the $D^0$ and $D^+$ lifetimes at Belle II

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We report a measurement of the $D^0$ and $D^+$ lifetimes using $D^0to K^-pi^+$ and $D^+to K^-pi^+pi^+$ decays reconstructed in $e^+e^-to cbar{c}$ data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+e^-$ collider. […]

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

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 […]
