Alexandre Vazdekis,Alexandre Vazdekis,Patricia Sanchez-Blazquez,Patricia Sanchez-Blazquez,Jesús Falcón-Barroso,Jesús Falcón-Barroso,A. J. Cenarro,A. J. Cenarro,Michael A. Beasley,Nicolás Cardiel,Javier Gorgas,Reynier Peletier +11 more
TL;DR: In this paper, the authors presented synthetic spectral energy distributions (SEDs) for single-age, single-metallicity stellar populations (SSPs) covering the full optical spectral range at moderately high resolution [full width at half-maximum (FWHM) = 2.3A].
Journal ArticleDOI
Wide-field precision kinematics of the m87 globular cluster system
Jay Strader,Aaron J. Romanowsky,Jean P. Brodie,Lee R. Spitler,Michael A. Beasley,Michael A. Beasley,Jacob A. Arnold,Naoyuki Tamura,Ray M. Sharples,Nobuo Arimoto +9 more
TL;DR: In this paper, the authors presented 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 the nearby Virgo Cluster.
Journal ArticleDOI
An overmassive Dark Halo around an Ultra-diffuse Galaxy in the Virgo Cluster
Michael A. Beasley,Michael A. Beasley,Aaron J. Romanowsky,Aaron J. Romanowsky,Vincenzo Pota,Ignacio Martin Navarro,Ignacio Martin Navarro,Ignacio Martin Navarro,David Martinez Delgado,Fabian Neyer,Aaron Deich +10 more
TL;DR: In this article, the authors measured a velocity dispersion of km s−1 within 8.1 kpc, corresponding to an enclosed mass of (4.5 ± 2.8) × 109M and a g-band mass-to-light ratio of within an effective radius.
Journal ArticleDOI
Extragalactic globular clusters: Old spectroscopic ages and new views on their formation
TL;DR: In this paper, a meta-analysis of Keck spectra of extragalactic globular clusters (GCs) in a sample of eight galaxies, ranging from dwarf galaxies to massive elliptical galaxies, was presented.
Journal ArticleDOI

Michael A. Beasley,Terry J. Bridges,Eric W. Peng,William E. Harris,Gretchen L. H. Harris,Duncan A. Forbes,G. Mackie +6 more
TL;DR: In this article, the authors performed a spectroscopic study of globular clusters (GCs) in the nearest giant elliptical NGC 5128 using the 2dF facility at the Anglo-Australian Telescope.
