Constraining the galaxy mass content in the core of A383 using velocity dispersion measurements for individual cluster members
A. Monna, S. Seitz, A. Zitrin +14
We use velocity dispersion measurements of 21 individual cluster members in the core of Abell 383, obtained with MMT Hectospec, to separate the galaxy and the smooth dark halo (DH)…
Properties of M31. V: 298 Eclipsing Binaries from PAndromeda
C. -H. Lee, J. Koppenhoefer, S. Seitz +12
The goal of this work is to conduct a photometric study of eclipsing binaries in M31. We apply a modified box-fitting algorithm to search for eclipsing binary candidates and determ…
Modelling the Transfer Function for the Dark Energy Survey
C. Chang, M. T. Busha, R. H. Wechsler +40
We present a forward-modelling simulation framework designed to model the data products from the Dark Energy Survey (DES). This forward-model process can be thought of as a transfe…
Structure Formation in Gas-Rich Galactic Discs with Finite Thickness: From Discs to Rings
Manuel Behrendt, Andreas Burkert, Marc Schartmann
Gravitational instabilities play an important role in structure formation of gas-rich high-redshift disc galaxies. In this paper, we revisit the axisymmetric perturbation theory an…
Photometric redshift analysis in the Dark Energy Survey Science Verification data
C. Sánchez, M. Carrasco Kind, H. Lin +74
We present results from a study of the photometric redshift performance of the Dark Energy Survey (DES), using the early data from a Science Verification (SV) period of observation…
Central rotations of Milky Way Globular Clusters
Maximilian H. Fabricius, Eva Noyola, Surangkhana Rukdee +6
Most Milky Way globular clusters (GCs) exhibit measurable flattening, even if on a very low level. Both cluster rotation and tidal fields are thought to cause this flattening. Neve…
Mass and galaxy distributions of four massive galaxy clusters from Dark Energy Survey Science Verification data
P. Melchior, E. Suchyta, E. Huff +89
We measure the weak-lensing masses and galaxy distributions of four massive galaxy clusters observed during the Science Verification phase of the Dark Energy Survey. This pathfinde…
Stellar Metallicity of the Extended Disk and Distance of the Spiral Galaxy NGC 3621
Rolf-Peter Kudritzki, Miguel A. Urbaneja, Fabio Bresolin +2
Low resolution ESO VLT/FORS spectra of blue supergiant stars are analyzed to determine stellar metallicities (based on elements such as Fe, Ti, Mg) in the extended disk of the spir…
Quantitative Spectroscopic J-band Study of Red Supergiants in Perseus OB-1
J. Zachary Gazak, Ben Davies, Rolf Kudritzki +2
We demonstrate how the metallicities of red supergiant (RSG) stars can be measured from quantitative spectroscopy down to resolutions of ~3000 in the J-band. We have obtained high…
A New Method for Measuring Metallicities of Young Super Star Clusters
J. Zachary Gazak, Ben Davies, Nate Bastian +7
We demonstrate how the metallicities of young super star clusters can be measured using novel spectroscopic techniques in the J-band. The near-infrared flux of super star clusters…
Re-growth of stellar disks in mature galaxies: The two component nature of NGC 7217 revisited with VIRUS-W
Maximilian H. Fabricius, Lodovico Coccato, Ralf Bender +6
Previous studies have reported the existence of two counter-rotating stellar disks in the early-type spiral galaxy NGC7217. We have obtained high-resolution optical spectroscopic d…
Properties of M31. IV: Candidate Luminous Blue Variables from PAndromeda
C. -H. Lee, S. Seitz, M. Kodric +16
We perform a study on the optical and infrared photometric properties of known luminous blue variables (LBVs) in M31 using the sample of LBV candidates from the Local Group Galaxy…
On the fine structure of the Cepheid metallicity gradient in the Galactic thin disk
K. Genovali, B. Lemasle, G. Bono +15
We present homogeneous and accurate iron abundances for 42 Galactic Cepheids based on high-spectral resolution (R~38,000) high signal-to-noise ratio (SNR>100) optical spectra colle…
The spectroscopic Hertzsprung-Russell diagram
N. Langer, R. P. Kudritzki
The Hertzsprung-Russell diagram is an essential diagnostic diagram for stellar structure and evolution, which has now been in use for more than 100 years. Our spectroscopic Hertzsp…
