The ongoing assembly of a central cluster galaxy: Phase-space substructures in the halo of M87
Aaron J. Romanowsky, Jay Strader, Jean P. Brodie +5
The halos of galaxies preserve unique records of their formation histories. We carry out the first combined observational and theoretical study of phase-space halo substructure in…
Wide-Field Precision Kinematics of the M87 Globular Cluster System
Jay Strader, Aaron Romanowsky, Jean Brodie +6
We present the most extensive combined photometric and spectroscopic study to date of the enormous globular cluster (GC) system around M87, the central giant elliptical galaxy in t…
The Fossil Record of Two-phase Galaxy Assembly: Kinematics and Metallicities in the Nearest S0 Galaxy
Jacob A. Arnold, Aaron J. Romanowsky, Jean P. Brodie +5
We present a global analysis of kinematics and metallicity in the nearest S0 galaxy, NGC 3115, along with implications for its assembly history. The data include high-quality wide-…
Global Properties of `Ordinary' Early-type Galaxies: photometry and spectroscopy of stars and globular clusters in NGC 4494
Caroline Foster, Lee R. Spitler, Aaron J. Romanowsky +7
We present a comprehensive analysis of the spatial, kinematic, and chemical properties of stars and globular clusters (GCs) in the `ordinary' elliptical galaxy NGC 4494 using data…
An extremely luminous panchromatic outburst from the nucleus of a distant galaxy
A. J. Levan, N. R. Tanvir, S. B. Cenko +58
Variable X-ray and gamma-ray emission is characteristic of the most extreme physical processes in the Universe, and studying the sources of these energetic photons has been a major…
