The Dragon-II simulations — III. Compact binary mergers in clusters with up to 1 million stars: mass, spin, eccentricity, merger rate and pair instability supernovae rate

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Manuel Arca Sedda, Albrecht W. H. Kamlah, Rainer Spurzem, Francesco Paolo Rizzuto, Mirek Giersz | Summary: Compact binary mergers forming in star clusters may exhibit distinctive features that can be used to identify them among observed gravitational-wave (GW) sources. Such features likely depend on the host cluster […]

The Dragon-II simulations — II. Formation mechanisms, mass, and spin of intermediate-mass black holes in star clusters with up to 1 million stars

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Manuel Arca Sedda, Albrecht W. H. Kamlah, Rainer Spurzem, Francesco Paolo Rizzuto, Mirek Giersz | Summary: The processes that govern the formation of intermediate-mass black holes (IMBHs) in dense stellar clusters are still unclear. Here, we discuss the role of stellar mergers, star-BH interactions and accretion, as […]

ECL: Class-Enhancement Contrastive Learning for Long-tailed Skin Lesion Classification

Kavli Affiliate: Ke Wang | First 5 Authors: Yilan Zhang, Jianqi Chen, Ke Wang, Fengying Xie, | Summary: Skin image datasets often suffer from imbalanced data distribution, exacerbating the difficulty of computer-aided skin disease diagnosis. Some recent works exploit supervised contrastive learning (SCL) for this long-tailed challenge. Despite achieving significant performance, these SCL-based methods focus […]

JWST reveals excess cool water near the snowline in compact disks, consistent with pebble drift

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Andrea Banzatti, Klaus M. Pontoppidan, John Carr, Evan Jellison, Ilaria Pascucci | Summary: Previous analyses of mid-infrared water spectra from young protoplanetary disks observed with the Spitzer-IRS found an anti-correlation between water luminosity and the millimeter dust disk radius observed with ALMA. This trend was suggested […]

The Radial Distribution and Excitation of H2 around Young Stars in the HST-ULLYSES Survey

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Kevin France, Nicole Arulanantham, Erin Maloney, P. Wilson Cauley, P. Abraham | Summary: The spatial distribution and evolution of gas in the inner 10 au of protoplanetary disks form the basis for estimating the initial conditions of planet formation. Among the most important constraints derived from […]
