On the contribution of dwarf galaxies to reionization of the Universe

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Zewei Wu, Andrey Kravtsov, , , | Summary: We present estimates of the ultraviolet (UV) and Lyman continuum flux density contributed by galaxies of luminosities from $M_{rm UV}approx -25$ to $M_{rm UV}=-4$ at redshifts $5leq zleq 10$ using a galaxy formation model that reproduces properties of local […]

The oldest stars with low neutron-capture element abundances and origins in ancient dwarf galaxies

Kavli Affiliate: Anna Frebel | First 5 Authors: Hillary Diane Andales, Ananda Santos Figueiredo, Casey Gordon Fienberg, Mohammad K. Mardini, Anna Frebel | Summary: We present a detailed chemical abundance and kinematic analysis of six extremely metal-poor ($-4.2 leq$ [Fe/H] $leq-$2.9) halo stars with very low neutron-capture abundances ([Sr/H] and [Ba/H]) based on high-resolution Magellan/MIKE […]

Localizing Task Information for Improved Model Merging and Compression

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Nikolaos Dimitriadis, Guillermo Ortiz-Jimenez, François Fleuret, Pascal Frossard | Summary: Model merging and task arithmetic have emerged as promising scalable approaches to merge multiple single-task checkpoints to one multi-task model, but their applicability is reduced by significant performance loss. Previous works have linked these drops […]

Long term variability of Cygnus X-1. VIII. A spectral-timing look at low energies with NICER

Kavli Affiliate: Erin Kara | First 5 Authors: Ole König, Guglielmo Mastroserio, Thomas Dauser, Mariano Méndez, Jingyi Wang | Summary: The Neutron Star Interior Composition Explorer (NICER) monitoring campaign of Cyg X-1 allows us to study its spectral-timing behavior at energies ${<}1$ keV across all states. The hard state power spectrum can be decomposed into […]

MaskFuser: Masked Fusion of Joint Multi-Modal Tokenization for End-to-End Autonomous Driving

Kavli Affiliate: Zheng Zhu | First 5 Authors: Yiqun Duan, Xianda Guo, Zheng Zhu, Zhen Wang, Yu-Kai Wang | Summary: Current multi-modality driving frameworks normally fuse representation by utilizing attention between single-modality branches. However, the existing networks still suppress the driving performance as the Image and LiDAR branches are independent and lack a unified observation […]

A systematic study of the ultra-fast outflow responses to luminosity variations in active galactic nuclei

Kavli Affiliate: Erin Kara | First 5 Authors: Yerong Xu, Ciro Pinto, Daniele Rogantini, Didier Barret, Stefano Bianchi | Summary: The extreme velocities and high ionization states of ultra-fast outflows (UFOs) make them a promising candidate for AGN feedback on the evolution of the host galaxy. However, their exact underlying driving mechanism is not yet […]

From traces to measures: Large language models as a tool for psychological measurement from text

Kavli Affiliate: Wei Gao | First 5 Authors: Joseph J. P. Simons, Wong Liang Ze, Prasanta Bhattacharya, Brandon Siyuan Loh, Wei Gao | Summary: Digital trace data provide potentially valuable resources for understanding human behaviour, but their value has been limited by issues of unclear measurement. The growth of large language models provides an opportunity […]
