The possible disappearance of a massive star in the low-metallicity galaxy PHL 293B
Andrew Allan,Jose H. Groh,Andrea Mehner,Nathan Smith,Ioana Boian,Eoin Farrell,Jennifer E. Andrews +6 more
TL;DR: In this paper, the authors investigate a suspected very massive star in one of the most metal-poor dwarf galaxies, PHL~293B, and find the sudden disappearance of the stellar signatures from their 2019 spectra, in particular the broad H lines with P~Cygni profiles that have been associated with a massive luminous blue variable (LBV) star.
Journal ArticleDOI
Nearby Supernova Rates from the Lick Observatory Supernova Search. II. The Observed Luminosity Functions and Fractions of Supernovae in a Complete Sample
Weidong Li,Jesse Leaman,Ryan Chornock,Ryan Chornock,Alexei V. Filippenko,Dovi Poznanski,Mohan Ganeshalingam,Xiaofeng Wang,Xiaofeng Wang,Xiaofeng Wang,Maryam Modjaz,Saurabh Jha,Saurabh Jha,Ryan J. Foley,Ryan J. Foley,Nathan Smith +15 more
TL;DR: In this paper, the observed luminosity functions (LFs) of supernovae were derived from the Lick Observatory Supernova Search (LOSS) data and a volume-limited sample of 175 SNe was constructed, and the observed (uncorrected for host-galaxy extinction) luminosity function was derived.

The Carina Nebula: A Laboratory for Feedback and Triggered Star Formation
Nathan Smith,Kate J. Brooks +1 more
TL;DR: The Carina Nebula (NGC 3372) as mentioned in this paper is the most extreme stellar population within a few kpc of the Sun, and suffers little interstellar extinction, and it is our best bridge between the detailed star-formation processes that can be studied in nearby regions like Orion, and much more extreme but also more distant regions like 30 Doradus.
Journal ArticleDOI
Searching for Highly Magnified Stars at Cosmological Distances: Discovery of a Redshift 0.94 Blue Supergiant in Archival Images of the Galaxy Cluster MACS J0416.1-2403.
Wenlei Chen,Patrick L. Kelly,Jose M. Diego,Masamune Oguri,Masamune Oguri,Liliya L. R. Williams,Adi Zitrin,Tommaso Treu,Nathan Smith,Tom Broadhurst,Tom Broadhurst,Tom Broadhurst,Nick Kaiser,Ryan J. Foley,Alexei V. Filippenko,Laura Salo,Jens Hjorth,Jonatan Selsing,Jonatan Selsing +18 more
TL;DR: In this article, the authors reported the discovery of a highly magnified star at redshift $z = 0.94$ in a strongly lensed arc behind a Hubble Frontier Field galaxy cluster, MACS J0416.1-2403.

Wyatt,Yang Yang +24 more
TL;DR: In this article, the authors present multiwavelength photometric and spectroscopic observations of SN 2019ein, a high-velocity Type Ia supernova (SN Ia) discovered in the nearby galaxy NGC 5353 with a two-day nondetection limit.
