Formation of the Little Red Dots from the Core-collapse of Self-interacting Dark Matter Halos

Fangzhou Jiang, Zixiang Jiang, Haonan Zheng, Luis C. Ho, Kohei Inayoshi | Summary: [[{“value”:”We present a statistical study on the formation and growth of black holes (BHs) seeded by gravothermal core-collapse of self-interacting dark matter (SIDM) halos at high redshifts, using a semi-analytical framework based on Monte-Carlo merger trees. We demonstrate that BH formation via […]

Galaxy Morphologies at Cosmic Noon with JWST : A Foundation for Exploring Gas Transport with Bars and Spiral Arms

Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Juan M. Espejo Salcedo, Stavros Pastras, Josef VĂ¡cha, Claudia Pulsoni, Reinhard Genzel | Summary: How radial flows shape galaxy structure and evolution remains an open question. Internal drivers of such flows, such as bars and spiral arms, known to mediate gas flows in the local Universe, are […]

Nonlinear Stability of Large-Period Traveling Waves Bifurcating from the Heteroclinic Loop in the FitzHugh-Nagumo Equation

Kavli Affiliate: Ke Wang | First 5 Authors: Ji Li, Ke Wang, Qiliang Wu, Qing Yu, | Summary: A wave front and a wave back that spontaneously connect two hyperbolic equilibria, known as a heteroclinic wave loop, give rise to periodic waves with arbitrarily large spatial periods through the heteroclinic bifurcation. The nonlinear stability of […]

To detect strong nugget with an acoustic array

Kavli Affiliate: Renxin Xu | First 5 Authors: Haoyang Qi, Renxin Xu, , , | Summary: This article discusses strong nuggets (SNs) which means strong interaction condensed matter clusters with a mass of about $10^6,$g. They may originate from the early universe, supernova, pulsar merger event, and so on. Depending on the equation of state, […]

Optimizing Safe and Aligned Language Generation: A Multi-Objective GRPO Approach

Kavli Affiliate: Zhuo Li | First 5 Authors: Xuying Li, Zhuo Li, Yuji Kosuga, Victor Bian, | Summary: Aligning large language models (LLMs) with human values and safety constraints is challenging, especially when objectives like helpfulness, truthfulness, and avoidance of harm conflict. Reinforcement Learning from Human Feedback (RLHF) has achieved notable success in steering models, […]
