Exploring the nature and synchronicity of early cluster formation in the Large Magellanic Cloud V: Multiple Populations in ancient Globular Clusters
Christina K. Gilligan, Brian Chaboyer, Jeffrey D. Cummings +9
We examine four ancient Large Magellanic Cloud (LMC) globular clusters (GCs) for evidence of multiple stellar populations using the Advanced Camera for Surveys and Wide Field Camer…
Exploring the nature and synchronicity of early cluster formation in the Large Magellanic Cloud IV: Evidence for Multiple Populations in Hodge 11 and NGC 2210
Christina K. Gilligan, Brian Chaboyer, Jeffrey D. Cummings +10
We present a multiple population search in two old Large Magellanic Cloud (LMC) Globular Clusters, Hodge 11 and NGC 2210. This work uses data from the Advanced Camera for Surveys a…
Exploring the nature and synchronicity of early cluster formation in the Large Magellanic Cloud: III. Horizontal Branch Morphology
R. Wagner-Kaiser, Dougal Mackey, Ata Sarajedini +5
We leverage new high-quality data from Hubble Space Telescope program GO-14164 to explore the variation in horizontal branch morphology among globular clusters in the Large Magella…
Exploring the nature and synchronicity of early cluster formation in the Large Magellanic Cloud: II. Relative ages and distances for six ancient globular clusters
R. Wagner-Kaiser, Dougal Mackey, Ata Sarajedini +6
We analyze Hubble Space Telescope observations of six globular clusters in the Large Magellanic Cloud from program GO-14164 in Cycle 23. These are the deepest available observation…
The Properties of the Magellanic Bridge Based on OGLE IV RR Lyrae Variables
R. Wagner-Kaiser, Ata Sarajedini
We examine the properties of the Magellanic Bridge connecting the Large and Small Magellanic Clouds using ab-type RR Lyrae variables from the extensive dataset of the Optical Gravi…
Large Magellanic Cloud Near-Infrared Synoptic Survey. II. The Wesenheit relations and their application to the Distance scale
Anupam Bhardwaj, Shashi M. Kanbur, Lucas M. Macri +4
We present new near-infrared Cepheid Period-Wesenheit relations in the LMC using time-series observations from the Large Magellanic Cloud Near-Infrared Synoptic Survey. We also der…
The Void in the Sculptor Group Spiral Galaxy NGC 247
R. Wagner-Kaiser, T. Demaio, A. Sarajedini +1
The dwarf galaxy NGC 247, located in the Sculptor Filament, displays an apparent void on the north side of its spiral disk. The existence of the void in the disk of this dwarf gala…
The Early Chemical Enrichment Histories of Two Sculptor Group Dwarf Galaxies as Revealed by RR Lyrae Variables
Soung-Chul Yang, Rachel Wagner-Kaiser, Ata Sarajedini +2
We present the results of our analysis of the RR Lyrae (RRL) variable stars detected in two transition-type dwarf galaxies (dTrans), ESO294-G010 and ESO410-G005 in the Sculptor gro…
The Properties of the Large Magellanic Cloud Based on OGLE III Photometry of RR Lyrae Stars
Rachel Wagner-Kaiser, Ata Sarajedini
We present results from a study of ab-type RR Lyrae variables in the Large Magellanic Cloud using the extensive dataset from phase III of the Optical Gravitational Lensing Experime…
Identifying Contributions to the Stellar Halo from Accreted, Kicked-Out, and In Situ Populations
Allyson A. Sheffield, Steven R. Majewski, Kathryn V. Johnston +10
[Abridged] We present a medium-resolution spectroscopic survey of late-type giant stars at mid-Galactic latitudes of (30), designed to probe the properties…
