Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc

open access: yesThe Astrophysical Journal Letters
It is well known that almost all isolated dwarf galaxies are actively forming stars. We report the discovery of dw1322m2053 (nicknamed Hedgehog), an isolated quiescent dwarf galaxy at a distance of 2.40 ± 0.15 Mpc with a stellar mass of M _⋆ ≈ 10 ^5.8 M ...

Clinical Validation of Artificial Intelligence Algorithms for the Diagnosis of Adult Obstructive Sleep Apnea and Sleep Staging From Oximetry and Photoplethysmography—SleepAI

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Home sleep apnea tests (HSATs) have emerged as alternatives to in‐laboratory polysomnography (PSG), but Type IV HSATs often show limited diagnostic performance. This study clinically validates SleepAI, a novel remote digital health system that applies AI algorithms to raw oximetry data for automated sleep staging and obstructive sleep apnea ...

The HST Legacy Archival Uniform Reduction of Local Group Imaging (LAURELIN). I. Photometry and Star Formation Histories for 36 Ultra-faint Dwarf Galaxies

open access: yesThe Astrophysical Journal
We present uniformly measured resolved stellar photometry and star formation histories (SFHs) for 36 nearby (≲400 kpc) ultra-faint dwarf galaxies (UFDs; −7.1 ≤ M _V ≤ +0.0) from new and archival Hubble Space Telescope (HST) imaging.

The Effect of Deep Brain Stimulation on Sleep and Cognition in Patients With Parkinson's Disease

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep–wake disturbances and cognitive decline are among the most common nonmotor symptoms of Parkinson's disease (PD). Deep brain stimulation (DBS) can successfully alleviate motor symptoms. However, the impact on sleep–wake disturbances and cognitive decline, and their interaction, is yet unclear.
