Kavli Affiliate: Erin Kara | First 5 Authors: Sibasish Laha, Eileen T. Meyer, Dev R. Sadaula, Ritesh Ghosh, Dhrubojyoti Sengupta | Summary: We present results from a high cadence multi-wavelength observational campaign of the enigmatic changing look AGN 1ES 1927+654 from May 2022- April 2024, coincident with an unprecedented radio flare (an increase in flux […]
Kavli Affiliate: Lile Wang | First 5 Authors: Lile Wang, , , , | Summary: The field of astrophysics has long sought computational tools capable of harnessing the power of modern GPUs to simulate the complex dynamics of astrophysical phenomena. The Kratos Framework, a novel GPU-based simulation system designed to leverage heterogeneous computing architectures, is […]

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 […]
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. […]

Kavli Affiliate: Erin Kara | First 5 Authors: Megan Masterson, Erin Kara, Christos Panagiotou, William N. Alston, Joheen Chakraborty | Summary: Recent discoveries from time-domain surveys are defying our expectations for how matter accretes onto supermassive black holes (SMBHs). The increased rate of short-timescale, repetitive events around SMBHs, including the newly-discovered quasi-periodic eruptions (QPEs), are […]

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Dong Yang, Xuchen Lin, Qifeng Huang, Zhijie Qu | Summary: We present the HI surface density ($Sigma_{rm HI}$) radial distributions based on total-power HI images obtained by FAST in the FEASTS program, for 35 galaxies with inclinations lower than 72 degree. We derive the HI […]
