LSST: from Science Drivers to Reference Design and Anticipated Data Products
Željko Ivezić, Steven M. Kahn, J. Anthony Tyson +310
(Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a sin…
The Evolutionary History of Galactic Bulges: Photometric and Spectroscopic Studies of Distant Spheroids in the GOODS Fields
Lauren A. MacArthur, Richard S. Ellis, Tommaso Treu +3
We report on the first results of a new study aimed at understanding the diversity and evolutionary history of distant galactic bulges in the context of now well-established trends…
The Fundamental Plane of Bulges at Intermediate Redshift
Lauren A. MacArthur, Richard S. Ellis, Tommaso Treu
We report on a new study aimed at understanding the diversity and evolutionary properties of distant galactic bulges in the context of well-established trends for pure spheroidal g…
Scaling Relations of Spiral Galaxies
S. Courteau, A. A. Dutton, F. van den Bosch +4
We construct a large data set of global structural parameters for 1300 field and cluster spiral galaxies and explore the joint distribution of luminosity L, optical rotation veloci…
Stellar Populations in Spiral Galaxies
Lauren A. MacArthur, Jesus Gonzalez, Stephane Courteau
We report preliminary results of the characterization of bulge and inner disk stellar populations for 8 nearby spiral galaxies using Gemini/GMOS. The long-slit spectra extend out t…
The Dynamical Distinction between Elliptical and Lenticular Galaxies in Distant Clusters: Further Evidence for the Recent Origin of S0 Galaxies
Sean M. Moran, Boon Liang Loh, Richard S. Ellis +3
We examine resolved spectroscopic data obtained with the Keck II telescope for 44 spheroidal galaxies in the fields of two rich clusters, Cl0024+16 (z=0.40) and MS0451-03 (z=0.54),…
A Library of Integrated Spectra of Galactic Globular Clusters
Ricardo P. Schiavon, James A. Rose, Stephane Courteau +1
We present a new library of integrated spectra of 40 Galactic globular clusters, obtained with the Blanco 4-m telescope and the R-C spectrograph at the Cerro Tololo Interamerican O…
Dust Sensitivity of Absorption-Line Indices
Lauren A. MacArthur
We investigate the effects of dust extinction on integrated absorption-line indices that are widely used to derive constraints on the ages and metallicities of composite stellar sy…
M31's Heavy Element Distribution and Outer Disk
Guy Worthey, Aubrey Espana, Lauren A. MacArthur +1
Hubble Space Telescope imaging of 11 fields in M31 were reduced to color-magnitude diagrams. The fields were chosen to sample all galactocentric radii to 50 kpc. Assuming that the…
The Identification of Blue Horizontal Branch Stars in the Integrated Spectra of Globular Clusters
Ricardo P. Schiavon, James A. Rose, Stephane Courteau +1
A major uncertainty in the spectroscopic dating of extragalactic globular clusters concerns the degenerate effect that age and horizontal branch morphology have on the strength of…
Structure of Disk Dominated Galaxies: II. Color Gradients and Stellar Population Models
Lauren A. MacArthur, Stephane Courteau, Eric Bell +1
(Abridged) We investigate optical and near-IR color gradients in a sample of 172 low-inclination galaxies spanning Hubble types S0--Irr. The colors are compared to stellar populati…
Scaling Relations of Local Spiral Galaxies.I. Observational Foundations
Stephane Courteau, Lauren A. MacArthur, Avishai Dekel +3
(Abridged) This paper presents an exploration of two fundamental scaling relations of spiral galaxies, the luminosity-rotation speed (or Tully-Fisher; TF) relation, and the size-lu…
The Tully-Fisher Relation of Barred Galaxies
Stephane Courteau, David R. Andersen, Matthew A. Bershady +2
We present new data exploring the scaling relations, such as the Tully-Fisher relation (TFR), of bright barred and unbarred galaxies. A primary motivation for this study is to esta…
Structure of Disk Dominated Galaxies I. Bulge/Disk Parameters, Simulations, and Secular Evolution
Lauren A. MacArthur, Stephane Courteau, Jon A. Holtzman
(Abridged) A robust analysis of galaxy structural parameters, based on the modeling of bulge and disk brightnesses in the BVRH bandpasses, is presented for 121 face-on and moderate…
