Accuracy and interpretability of smartwatch electrocardiogram for early detection of atrial fibrillation: A systematic review and meta-analysis. [PDF]

open access: yesJ Arrhythm
The smartwatch ECG algorithm achieved 86% sensitivity and 94% specificity with an sAUC of 96%, while manual readings by trained personnel reached 96% sensitivity, 95% specificity, and an sAUC of 98% in a brand‐specific subgroup analysis. These findings demonstrate that the smartwatch ECG detects AFib, although 3% of results are unreadable.

Outlier Detection in the DESI Bright Galaxy Survey

open access: yesThe Astrophysical Journal Letters, 2023
We present an unsupervised search for outliers in the Bright Galaxy Survey (BGS) data set from the DESI Early Data Release. This analysis utilizes an autoencoder to compress galaxy spectra into a compact, redshift-invariant latent space, and a ...

Searches for Extremely Metal-poor Galaxies Using Arecibo Legacy Fast ALFA–Selected Dwarf Galaxies

open access: yesThe Astrophysical Journal, 2023
We present a study of nearby dwarf galaxies selected from the Arecibo Legacy Fast ALFA (ALFALFA) blind H i survey. A primary goal of the project was to utilize a nonstandard selection method with the hope of detecting previously unrecognized extremely ...

Pavo: Discovery of a Star-forming Dwarf Galaxy Just Outside the Local Group

open access: yesThe Astrophysical Journal Letters, 2023
We report the discovery of Pavo, a faint ( M _V = −10.0), star-forming, irregular, and extremely isolated dwarf galaxy at D ≈ 2 Mpc. Pavo was identified in Dark Energy Camera Legacy Survey imaging via a novel approach that combines low surface brightness

Disk Galaxies Are Self-similar: The Universality of the H i-to-Halo Mass Ratio for Isolated Disks

open access: yesThe Astrophysical Journal Letters, 2023
Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter.

THE CRITERIA FOR MORPHOLOGICAL CLASSIFICATION OF PF GALAXY CLUSTERS

open access: yesOdessa Astronomical Publications, 2013
The morphological types of galaxy clusters resulting from their out ward appearance is physically related to the clusters and their member galaxies. Presented here is an adopted system of morphological types of galaxy clusters based on the Zwicky, Boutz ...

The intrinsic shapes of dwarf irregular galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2013
Abstract We use the measured B-band axial ratios of galaxies from an updated catalogue of Local Volume galaxies to determine the intrinsic shape of dwarf irregular galaxies (de Vaucouleurs’ morphological types 8–10). We find that the shapes change systematically with luminosity, with fainter galaxies being thicker.

Galaxy Morphological Classification of the Legacy Surveys with Deformable Convolutional Neural Networks

open access: yesThe Astronomical Journal, 2023
The ongoing and forthcoming surveys will result in an unprecedented increase in the number of observed galaxies. As a result, data-driven techniques are now the primary methods for analyzing and interpreting this vast amount of information.
