Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Taylor J. Hoyt, In Sung Jang, Wendy L. Freedman, Barry F. Madore, Kayla A. Owens | Summary: We present distances to ten supernova (SN) host galaxies determined via the red giant branch tip (TRGB) using JWST/NIRCAM and the F115W, F356W, and F444W bandpasses. Our analysis, including […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Francesco D’Eugenio, Roberto Maiolino, Michele Perna, Hannah Uebler, Xihan Ji | Summary: JWST spectroscopy has revealed a population of compact objects at redshifts $z=2$-9 with `v’-shaped spectral energy distributions, broad permitted lines, and, often, hydrogen Balmer absorption. Among these `Little Red Dots’ (LRDs), Abell2744-QSO1 at $z=7.04$ has […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Ruth M. E. Kelly, Herman L. Marshall, Silvia Zane, Nabil Brice, Swati Ravi | Summary: X-ray polarimetry offers a unique window into neutron star physics and can provide answers to questions that cannot otherwise be probed. The up-and-coming REDSoX sounding rocket mission will be the first […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Lei He, Kun Liu, Yan Deng, Wenning Wei | Summary: Large Multimodal Models (LMMs) have demonstrated exceptional performance across a wide range of domains. This paper explores their potential in pronunciation assessment tasks, with a particular focus on evaluating the capabilities of the Generative Pre-trained […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Yang A. Li, Luis C. Ho, Jinyi Shangguan, Zhao-Yu Li, Yingjie Peng | Summary: Quiescent galaxies (QGs) typically have little cold gas to form stars. The discovery of gas-rich QGs challenges our conventional understanding of the evolutionary paths of galaxies. We take advantage of a new […]

Kavli Affiliate: Roger Blandford | First 5 Authors: Paul Simeon, Noémie Globus, Kirk S. S. Barrow, Roger Blandford, | Summary: We propose that a hierarchical shock model$unicode{x2014}$including supernova remnant shocks, galactic wind termination shocks, and accretion shocks around cosmic filaments and galaxy clusters$unicode{x2014}$can naturally explain the cosmic ray spectrum from ~1 GeV up to ~200 […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Ella Werre, David Robinson, Camille Avestruz, Nickolay Y. Gnedin, | Summary: Quasar absorption lines provide a unique window to the relationship between galaxies and the intergalactic medium during the Epoch of Reionization. In particular, high redshift quasars enable measurements of the neutral hydrogen content of the […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Weihao Xuan, Rui Yang, Heli Qi, Qingcheng Zeng, Yunze Xiao | Summary: Traditional benchmarks struggle to evaluate increasingly sophisticated language models in multilingual and culturally diverse contexts. To address this gap, we introduce MMLU-ProX, a comprehensive multilingual benchmark covering 13 typologically diverse languages with approximately 11,829 […]
