The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems V: Do Self-Consistent Atmospheric Models Represent JWST Spectra? A Showcase With VHS 1256 b

Posted by dbos Stanford

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Simon Petrus, Niall Whiteford, Polychronis Patapis, Beth A. Biller, Andrew Skemer | Summary: The unprecedented medium-resolution (R~1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (140+/-20Myr) low-mass (12-20MJup) L-T transition (L7) companion VHS1256b gives access to a catalogue of molecular absorptions. In this study, […]

Bayesian estimation of cross-coupling and reflection systematics in 21cm array visibility data

Posted by dbos MIT

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Geoff G. Murphy, Philip Bull, Mario G. Santos, Zara Abdurashidova, Tyrone Adams | Summary: Observations with radio arrays that target the 21-cm signal originating from the early Universe suffer from a variety of systematic effects. An important class of these are reflections and spurious couplings between […]

On the existence, rareness and uniqueness of quenched HI-rich galaxies in the local Universe

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Xiao Li, Cheng Li, H. J. Mo, Jianhong Hu, Jing Wang | Summary: Using data from ALFALFA, xGASS, HI-MaNGA and SDSS, we identify a sample of 47 "red but HI-rich"(RR) galaxies with $NUV-r > 5$ and unusually high HI-to-stellar mass ratios. We compare the optical properties and […]

GA-NIFS: JWST discovers an offset AGN 740 million years after the Big Bang

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Hannah Übler, Roberto Maiolino, Pablo G. Pérez-González, Francesco D’Eugenio, Michele Perna | Summary: A surprising finding of recent studies is the large number of Active Galactic Nuclei (AGN) associated with moderately massive black holes ($rm log(M_bullet/M_odot)sim 6-8$), in the first billion years after the Big Bang ($z>5$). […]

PneumoLLM: Harnessing the Power of Large Language Model for Pneumoconiosis Diagnosis

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Meiyue Song, Zhihua Yu, Jiaxin Wang, Jiarui Wang, Yuting Lu | Summary: The conventional pretraining-and-finetuning paradigm, while effective for common diseases with ample data, faces challenges in diagnosing data-scarce occupational diseases like pneumoconiosis. Recently, large language models (LLMs) have exhibits unprecedented ability when conducting multiple tasks in […]
