Time-resolved Hubble Space Telescope UV observations of an X-ray quasi-periodic eruption source

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Thomas Wevers, Muryel Guolo, Sean Lockwood, Andrew Mummery, Dheeraj R. Pasham | Summary: X-ray quasi-periodic eruptions (QPEs) are a novel mode of variability in nearby galactic nuclei whose origin remains unknown. Their multi-wavelength properties are poorly constrained, as studies have focused almost entirely on the X-ray […]

Clumps as multiscale structures in cosmic noon galaxies

Kavli Affiliate: John D. Silverman | First 5 Authors: Boris S Kalita, Tomoko L Suzuki, Daichi Kashino, John D Silverman, Emanuele Daddi | Summary: Star-forming clumps have been found to significantly influence the star formation of gas-rich $z>1$ galaxies. Using public data from JWST/NIRCam (COSMOS-Web) and ALMA (FMOS-COSMOS), we study a sample of 32 massive […]

A multi-wavelength investigation of spiral structures in $z > 1$ galaxies with JWST

Kavli Affiliate: John D. Silverman | First 5 Authors: Boris S. Kalita, Si-Yue Yu, John D. Silverman, Emanuele Daddi, Luis C. Ho | Summary: Recent JWST observations have revealed the prevalence of spiral structures at $z > 1$. Unlike in the local Universe, the origin and the consequence of spirals at this epoch remain unexplored. […]

SDPO: Segment-Level Direct Preference Optimization for Social Agents

Kavli Affiliate: Ke Wang | First 5 Authors: Aobo Kong, Wentao Ma, Shiwan Zhao, Yongbin Li, Yuchuan Wu | Summary: Social agents powered by large language models (LLMs) can simulate human social behaviors but fall short in handling complex goal-oriented social dialogues. Direct Preference Optimization (DPO) has proven effective in aligning LLM behavior with human […]

Enhanced Condensation Through Rotation

Kavli Affiliate: Frank Wilczek | First 5 Authors: Maxim Chernodub, Frank Wilczek, , , | Summary: We argue that the rotation of a thin superconducting cylinder can increase the critical temperature of the superconducting phase transition substantially. The phenomenon can be interpreted as an effective negative moment of inertia associated with condensation of Cooper pairs. […]
