Low-density star cluster formation: discovery of a young faint fuzzy on the outskirts of the low-mass spiral galaxy NGC 247

Aaron J. Romanowsky, Søren S. Larsen, Alexa Villaume +21

The classical globular clusters found in all galaxy types have half-light radii of 2-4 pc, which have been tied to formation in the dense cores of giant molecular…

The AUGUST Two-Sample Test: Powerful, Interpretable, and Fast

Benjamin Brown, Kai Zhang

Two-sample testing is a fundamental problem in statistics, and many famous two-sample tests are designed to be fully non-parametric. These existing methods perform well with locati…

Partly burnt runaway stellar remnants from peculiar thermonuclear supernovae

R. Raddi, M. A. Hollands, D. Koester +13

We report the discovery of three stars that, along with the prototype LP40-365, form a distinct class of chemically peculiar runaway stars that are the survivors of thermonuclear e…

Anatomy of the hyper-runaway star LP 40-365 with Gaia

R. Raddi, M. A. Hollands, B. T. Gaensicke +4

LP 40-365 (aka GD 492) is a nearby low-luminosity hyper-runaway star with an extremely unusual atmospheric composition, which has been proposed as the remnant of a white dwarf that…

Further insight on the hypervelocity white dwarf, LP 40-365 (GD 492): a nearby emissary from a single-degenerate Type Ia supernova

R. Raddi, M. A. Hollands, D. Koester +4

The recently discovered hypervelocity white dwarf LP 40-65 (aka GD 492) has been suggested as the outcome of the failed disruption of a white dwarf in a sub-luminous Type Ia supern…

Unusually High Metallicity Host Of The Dark LGRB 051022

J. F. Graham, A. S. Fruchter, L. J. Kewley +5

We present spectroscopy of the host of GRB 051022 with GMOS nod and shuffle on Gemini South and NIRSPEC on Keck II. We determine a metallicity for the host of log(O/H)+12 = 8.77 us…
