Dominant Role of Coplanar Inflows in Driving Disk Evolution Revealed by Gas-Phase Metallicity Gradients

Posted by dbos Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Cheqiu Lyu, Enci Wang, Hongxin Zhang, Yingjie Peng, Xin Wang | Summary: Using spatially resolved spectroscopic data from the MaNGA sample, we investigate the parameters influencing the radial gradients of gas-phase metallicity ($nablalog(mathrm{O/H})$), to determine whether disk formation is primarily driven by coplanar gas inflow or by […]

LanP: Rethinking the Impact of Language Priors in Large Vision-Language Models

Posted by dbos Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Zongyu Wu, Yuwei Niu, Hongcheng Gao, Minhua Lin, Zhiwei Zhang | Summary: Large Vision-Language Models (LVLMs) have shown impressive performance in various tasks. However, LVLMs suffer from hallucination, which hinders their adoption in the real world. Existing studies emphasized that the strong language priors of LVLMs can […]

Learning decouples accuracy and reaction time for rapid decisions in a transitive inference task

Posted by dbos Columbia

Kavli Affiliate: Vincent Ferrera | Authors: Fabian A Munoz Silva, Greg Jensen, Maxwell Shinn, Yelda Alkan, John Murray, Herbert Terrace and Vincent P Ferrera | Summary: The accumulation of evidence over time formalized in the drift diffusion model (DDM), has become one of the most prevalent models of deliberative decision-making. To better understand the role […]

The life cycle of giant molecular clouds in simulated Milky Way-mass galaxies

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Yang Ni, Hui Li, Mark Vogelsberger, Laura V. Sales, Federico Marinacci | Summary: In this work, we trace the complete life cycle of individual GMCs in high-resolution Milky Way-mass galaxy simulations to determine how different stellar feedback mechanisms and galactic-scale processes govern cloud lifetimes, mass evolution, and […]

JADES: Average Nitrogen Enhancement in High-Redshift Broad-Line Active Galactic Nuclei

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Yuki Isobe, Roberto Maiolino, Francesco D’Eugenio, Mirko Curti, Xihan Ji | Summary: The unexpectedly high nitrogen-to-oxygen (N/O) ratios observed in high-redshift (z) galaxies have challenged our understanding of early star formation. Notably, many of these nitrogen-rich galaxies show signatures of active galactic nuclei (AGNs), suggesting a possible […]

Active Solids: Defect Self-Propulsion Without Flow

Posted by dbos UCSB

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Fridtjof Brauns, Myles O’Leary, Arthur Hernandez, Mark J. Bowick, M. Cristina Marchetti | Summary: The self-propulsion of +1/2 topological defects is a hallmark of active nematic fluids, where the defects are advected by the flow field they themselves generate. In this paper we propose a minimal […]
