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

Posted by dbos Peking

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

Posted by dbos Peking

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 […]

No evidence of AGN features in the nuclei of Arp 220 from JWST/NIRSpec IFS

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Michele Perna, Santiago Arribas, Isabella Lamperti, Miguel Pereira-Santaella, Lorenzo Ulivi | Summary: Arp 220 is the nearest ULIRG; it shows evidence of 100 pc-scale molecular outflows likely connected with galaxy-scale outflows traced by ionised and neutral gas. The two highly obscured nuclei of Arp 220 are the […]

Continuous Bump Attractor Networks Require Explicit Error Coding for Gain Recalibration

Posted by klaurent Hopkins

Kavli Affiliate: James Knierim | Authors: Gorkem Secer, James J. Knierim and Noah J. Cowan | Summary: Representations of continuous variables are crucial to create internal models of the external world. A prevailing model of how the brain maintains these representations is given by continuous bump attractor networks (CBANs) in a broad range of brain […]
