Interstellar Absorption Lines in the Direction of the Cataclysmic Variable SS Cygni
Adam M. Ritchey, George Wallerstein, Jean McKeever
We present an analysis of interstellar absorption lines in high-resolution optical echelle spectra of SS Cyg obtained during an outburst in 2013 June and in archival Hubble Space T…
Chemical Cartography with APOGEE: Large-scale Mean Metallicity Maps of the Milky Way
Michael R. Hayden, Jon A. Holtzman, Jo Bovy +27
We present Galactic mean metallicity maps derived from the first year of the SDSS-III APOGEE experiment. Mean abundances in different zones of Galactocentric radius (0 < R < 15 kpc…
CHANG-ES III: UGC10288 -- An Edge-on Galaxy with a Background Double-lobed Radio Source
Judith Irwin, Marita Krause, Jayanne English +7
This 3rd paper in the CHANG-ES series shows the first results from our regular data taken with the Karl G. Jansky Very Large Array (JVLA). The edge-on galaxy, UGC 10288, has been o…
A Search for Planetary Nebulae With the SDSS: the outer regions of M31
A. Y. Kniazev, E. K. Grebel, D. B. Zucker +3
We have developed a method to identify planetary nebula (PN) candidates in imaging data of the Sloan Digital Sky Survey (SDSS). This method exploits the SDSS' five-band sampling of…
Chemodynamics of the Milky Way. I. The first year of APOGEE data
F. Anders, C. Chiappini, B. X. Santiago +38
We investigate the chemo-kinematic properties of the Milky Way disc by exploring the first year of data from the Apache Point Observatory Galactic Evolution Experiment (APOGEE), an…
Measuring Metallicities with HST/WFC3 photometry
Teresa L. Ross, Jon Holtzman, Barbara J. Anthony-Twarog +4
We quantified and calibrated the metallicity and temperature sensitivities of colors derived from nine Wide Field Camera 3 (WFC3) filters aboard the Hubble Space Telescope using Da…
A new stellar chemo-kinematic relation reveals the merger history of the Milky Way disc
I. Minchev, C. Chiappini, M. Martig +27
The velocity dispersions of stars near the Sun are known to increase with stellar age, but age can be difficult to determine so a proxy like the abundance of alpha elements (e.g.,…
Discovery of a Dynamical Cold Point in the Heart of the Sagittarius dSph Galaxy with Observations from the APOGEE Project
Steven R. Majewski, Sten Hasselquist, Ewa L. Łokas +30
The dynamics of the core of the Sagittarius (Sgr) dwarf spheroidal (dSph) galaxy are explored using high-resolution (R~22,500), H-band, near-infrared spectra of over 1,000 giant st…
The Open Cluster Chemical Analysis and Mapping Survey: Local Galactic Metallicity Gradient with APOGEE using SDSS DR10
Peter M. Frinchaboy, Benjamin Thompson, Kelly M. Jackson +31
The Open Cluster Chemical Analysis and Mapping (OCCAM) Survey aims to produce a comprehensive, uniform, infrared-based dataset for hundreds of open clusters, and constrain key Gala…
Hypervelocity Star Candidates in the SEGUE G & K Dwarf Sample
Lauren E. Palladino, Katharine J. Schlesinger, Kelly Holley-Bockelmann +4
We present 20 candidate hypervelocity stars from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) G and K dwarf samples. Previous searches for hypervelocity s…
The AGORA High-Resolution Galaxy Simulations Comparison Project
Ji-hoon Kim, Tom Abel, Oscar Agertz +43
We introduce the AGORA project, a comprehensive numerical study of well-resolved galaxies within the LCDM cosmology. Cosmological hydrodynamic simulations with force resolutions of…
MAGIICAT III. Interpreting Self-Similarity of the Circumgalactic Medium with Virial Mass using MgII Absorption
Christopher W. Churchill, Sebastian Trujillo-Gomez, Nikole M. Nielsen +1
In Churchill et al., we used halo abundance matching applied to 182 galaxies in the MgII Absorber-Galaxy Catalog (MAGIICAT, Nielsen et al.) and showed that the mean MgII 2796 equiv…
Target Selection for the Apache Point Observatory Galactic Evolution Experiment (APOGEE)
G. Zasowski, Jennifer A. Johnson, P. M. Frinchaboy +43
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a high-resolution infrared spectroscopic survey spanning all Galactic environments (i.e., bulge, disk, and ha…
HALOGAS observations of NGC 5023 and UGC 2082: Modeling of non-cylindrically symmetric gas distributions in edge-on galaxies
P. Kamphuis, R. J. Rand, G. I. G. Józsa +7
In recent years it has become clear that the vertical structure of disk galaxies is a key ingredient for understanding galaxy evolution. In particular, the presence and structure o…
Does the Oosterhoff Dichotomy Exist in The Andromeda Galaxy? I. The case of G11
Rodrigo Contreras Ramos, Gisella Clementini, Luciana Federici +8
We present the first evidence that Oosterhoff type II globular clusters exist in the Andromeda galaxy (M31). On the basis of time-series photometry of the moderately metal-poor ([F…
