Modeling the inner part of the jet in M87: Confronting jet morphology with theory

Kavli Affiliate: Feng Yuan | First 5 Authors: Hai Yang, Feng Yuan, Hui Li, Yosuke Mizuno, Fan Guo | Summary: The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole ("BZ-jet") or the […]

Sample and Communication Efficient Fully Decentralized MARL Policy Evaluation via a New Approach: Local TD update

Kavli Affiliate: Jia Liu | First 5 Authors: Fnu Hairi, Zifan Zhang, Jia Liu, , | Summary: In actor-critic framework for fully decentralized multi-agent reinforcement learning (MARL), one of the key components is the MARL policy evaluation (PE) problem, where a set of $N$ agents work cooperatively to evaluate the value function of the global […]

Runaway Gravitational Production of Dark Photons

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: We demonstrate that gravitational particle production (GPP) of a massive, Abelian, vector (Proca) field during inflation in the presence of nonminimal coupling to gravity may suffer from an instability which leads to runaway production of […]

K-theoretic Heisenberg algebras and permutation-equivariant Gromov–Witten theory

Kavli Affiliate: Todor Milanov | First 5 Authors: Todor Milanov, , , , | Summary: We found an interesting application of the K-theoretic Heisenberg algebras of Weiqiang Wang to the foundations of permutation equivariant K-theoretic Gromov–Witten theory. We also found an explicit formula for the genus 0 correlators in the permutation equivariant Gromov–Witten theory of […]

Connection between galaxy morphology and dark-matter halo structure I: a running threshold for thin discs and size predictors from the dark sector

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jinning Liang, Fangzhou Jiang, Houjun Mo, Andrew Benson, Avishai Dekel | Summary: We present a series of studies on the connection between galaxy morphology and the structure of host dark-matter (DM) haloes using cosmological simulations. In this work, we introduce a new kinematic decomposition scheme that […]

Empowering Segmentation Ability to Multi-modal Large Language Models

Kavli Affiliate: Jing Wang | First 5 Authors: Yuqi Yang, Peng-Tao Jiang, Jing Wang, Hao Zhang, Kai Zhao | Summary: Multi-modal large language models (MLLMs) can understand image-language prompts and demonstrate impressive reasoning ability. In this paper, we extend MLLMs’ output by empowering MLLMs with the segmentation ability. The extended MLLMs can both output language […]
