HALO7D I: The Line of Sight Velocities of Distant Main Sequence Stars in the Milky Way Halo
Emily C. Cunningham, Alis J. Deason, Constance M. Rockosi +5
The Halo Assembly in Lambda-CDM: Observations in 7 Dimensions (HALO7D) dataset consists of Keck II/DEIMOS spectroscopy and Hubble Space Telescope-measured proper motions of Milky W…
The SLUGGS Survey: The mass distribution in early-type galaxies within five effective radii and beyond
Adebusola B. Alabi, Duncan A. Forbes, Aaron J. Romanowsky +11
We study mass distributions within and beyond 5~effective radii () in 23 early-type galaxies from the SLUGGS survey, using their globular cluster (GC) kinematic data. Th…
The SLUGGS survey: Exploring the globular cluster systems of the Leo II group and their global relationships
Sreeja S. Kartha, Duncan A. Forbes, Adebusola B. Alabi +6
We present an investigation of the globular cluster (GC) systems of NGC 3607 and NGC 3608 as part of the ongoing SLUGGS survey. We use wide-field imaging data from the Subaru teles…
Satellite accretion in action: a tidally disrupting dwarf spheroidal around the nearby spiral galaxy NGC 253
Aaron J. Romanowsky, D. Martinez-Delgado, Nicolas F. Martin +7
We report the discovery of NGC 253-dw2, a dwarf spheroidal (dSph) galaxy candidate undergoing tidal disruption around a nearby spiral galaxy, NGC 253 in the Sculptor group: the fir…
NGC 3628-UCD1: A possible Cen Analog Embedded in a Stellar Stream
Zachary G. Jennings, Aaron J. Romanowsky, Jean P. Brodie +6
Using Subaru/Suprime-Cam wide-field imaging and both Keck/ESI and LBT/MODS spectroscopy, we identify and characterize a compact star cluster, which we term NGC 3628-UCD1, embedded…
Hiding in plain sight: record-breaking compact stellar systems in the Sloan Digital Sky Survey
Michael A. Sandoval, Richard P. Vo, Aaron J. Romanowsky +10
Motivated by the recent, serendipitous discovery of the densest known galaxy, M60-UCD1, we present two initial findings from a follow-up search, using the Sloan Digital Sky Survey,…
The SLUGGS survey: Combining stellar and globular cluster metallicities in the outer regions of early-type galaxies
Nicola Pastorello, Duncan A. Forbes, Christopher Usher +9
The outer halo regions of early-type galaxies carry key information about their past accretion history. However, spectroscopically probing the stellar component at such galactocent…
A SLUGGS and Gemini/GMOS combined study of the elliptical galaxy M60: wide-field photometry and kinematics of the globular cluster system
Vincenzo Pota, Jean P. Brodie, Terry Bridges +20
We present new wide-field photometry and spectroscopy of the globular clusters (GCs) around NGC 4649 (M60), the third brightest galaxy in the Virgo cluster. Imaging of NGC 4649 was…
The Supernova Progenitor Mass Distributions of M31 and M33: Further Evidence for an Upper Mass Limit
Zachary G. Jennings, Benjamin F. Williams, Jeremiah W. Murphy +5
Using Hubble Space Telescope (HST) photometry to measure star formation histories, we age-date the stellar populations surrounding supernova remnants (SNRs) in M31 and M33. We then…
The SAGES Legacy Unifying Globulars and GalaxieS Survey (SLUGGS): Sample definition, methods, and initial results
Jean P. Brodie, Aaron J. Romanowsky, Jay Strader +14
We introduce and provide the scientific motivation for a wide-field photometric and spectroscopic chemodynamical survey of nearby early-type galaxies (ETGs) and their globular clus…
The SLUGGS Survey: HST/ACS Mosaic Imaging of the NGC 3115 Globular Cluster System
Zachary G. Jennings, Jay Strader, Aaron J. Romanowsky +6
We present HST/ACS and photometry and half-light radii measurements of 360 globular cluster (GC) candidates around the nearby S0 galaxy NGC 3115. We also includ…
Globular clusters of NGC 3115 in the near-infrared. Demonstrating the correctness of two opposing scenarios
Michele Cantiello, John P. Blakeslee, Gabriella Raimondo +4
We combined new near-infrared VLT/HAWK-I data of the globular clusters (GCs) in the isolated edge-on S0 galaxy NGC 3115 with optical and spectroscopic ones taken from the literatur…
Supernova Remnant Progenitor Masses in M31
Zachary G. Jennings, Benjamin F. Williams, Jeremiah W. Murphy +5
Using HST photometry, we age-date 59 supernova remnants (SNRs) in the spiral galaxy M31 and use these ages to estimate zero-age main sequence masses (MZAMS) for their progenitors.…
