Evidence of a population of dark subhalos from Gaia and Pan-STARRS observations of the GD-1 stream
Nilanjan Banik, Jo Bovy, Gianfranco Bertone +2
New data from the satellite, when combined with accurate photometry from the Pan-STARRS survey, allow us to accurately estimate the properties of the GD-1 stream. H…
On the nature of a shell of young stars in the outskirts of the Small Magellanic Cloud
David Martinez-Delgado, A. Katherina Vivas, Eva K. Grebel +35
Understanding the evolutionary history of the Magellanic Clouds requires an in-depth exploration and characterization of the stellar content in their outer regions, which ultimatel…
Globular cluster number density profiles using Gaia DR2
T. J. L. de Boer, M. Gieles, E. Balbinot +4
Using data from Gaia DR2, we study the radial number density profiles of the Galactic globular cluster sample. Proper motions are used for accurate membership selection, especially…
Exploring the Very Extended Low Surface Brightness Stellar Populations of the Large Magellanic Cloud with SMASH
David L. Nidever, Knut Olsen, Yumi Choi +23
We present the detection of very extended stellar populations around the Large Magellanic Cloud (LMC) out to R~21 degrees, or ~18.5 kpc at the LMC distance of 50 kpc, as detected i…
SMASHing THE LMC: Mapping a Ring-like Stellar Overdensity in the LMC Disk
Yumi Choi, David L. Nidever, Knut Olsen +18
We explore the stellar structure of the Large Magellanic Cloud (LMC) disk using data from the Survey of the MAgellanic Stellar History (SMASH) and the Dark Energy Survey. We detect…
A deeper look at the GD1 stream: density variations and wiggles
T. J. L. de Boer, V. Belokurov, S. E. Koposov +4
Using deep photometric data from CFHT/Megacam, we study the morphology and density of the GD-1 stream, one of the longest and coldest stellar streams in the Milky Way. Our deep dat…
A unified model for age-velocity dispersion relations in Local Group galaxies: Disentangling ISM turbulence and latent dynamical heating
Ryan Leaman, J. Trevor Mendel, Emily Wisnioski +9
We analyze age-velocity dispersion relations (AVRs) from kinematics of individual stars in eight Local Group galaxies ranging in mass from Carina () to M31 ($M_{…
The fall of the Northern Unicorn: Tangential motions in the Galactic Anti-centre with SDSS and Gaia
T. J. L. de Boer, V. Belokurov, S. E. Koposov
We present the first detailed study of the behaviour of the stellar proper motion across the entire Galactic Anti-centre area visible in the Sloan Digital Sky Survey data. We use r…
The star formation history of the Sagittarius stream
T. J. L. de Boer, V. Belokurov, S. Koposov
We present the first detailed quantitative study of the stellar populations of the Sagittarius (Sgr) streams within the Stripe 82 region, using photometric and spectroscopic observ…
