Evolution of Broad-line Emission from Active Galactic Nuclei
Moshe Elitzur, Luis C. Ho, Jonathan R. Trump
Apart from viewing-dependent obscuration, intrinsic broad-line emission from active galactic nuclei (AGNs) follows an evolutionary sequence: Type …
A Comparison between Semi-Analytic Model Predictions for the CANDELS Survey
Yu Lu, Risa H. Wechsler, Rachel S. Somerville +13
We compare the predictions of three independently developed semi-analytic galaxy formation models that are being used to aid in the interpretation of results from the CANDELS surve…
AGN X-ray variability in the XMM-COSMOS survey
G. Lanzuisi, G. Ponti, M. Salvato +18
We took advantage of the observations carried out by XMM in the COSMOS field during 3.5 years, to study the long term variability of a large sample of AGN (638 sources), in a wide…
Constraints on the merging channel of massive galaxies since z~1
I. Ferreras, I. Trujillo, E. Mármol-Queraltó +8
(Abridged) We probe the merging channel of massive galaxies over the z=0.3-1.3 redshift window by studying close pairs in a sample of 238 galaxies with stellar mass >1E11Msun, from…
The colour distribution of galaxies at redshift five
A. B. Rogers, R. J. McLure, J. S. Dunlop +11
We present the results of a study investigating the rest-frame ultra-violet (UV) spectral slopes of redshift z~5 Lyman-break galaxies (LBGs). By combining deep Hubble Space Telesco…
MOND and IMF variations in early-type galaxies from
C. Tortora, A. J. Romanowsky, V. F. Cardone +2
MOdified Newtonian dynamics (MOND) represents a phenomenological alternative to dark matter (DM) for the missing mass problem in galaxies and clusters of galaxies. We analyze the c…
FIRST, a fibered aperture masking instrument II. Spectroscopy of the Capella binary system at the diffraction limit
E. Huby, G. Duchêne, F. Marchis +7
FIRST is a prototype instrument built to demonstrate the capabilities of the pupil remapping technique, using single-mode fibers and working at visible wavelengths. We report on ob…
Confirmation of Small Dynamical and Stellar Masses for Extreme Emission Line Galaxies at z~2
Michael V. Maseda, Arjen van der Wel, Elisabete da Cunha +21
Spectroscopic observations from the Large Binocular Telescope and the Very Large Telescope reveal kinematically narrow lines (~50 km/s) for a sample of 14 Extreme Emission Line Gal…
A CANDELS - 3D-HST Synergy: Resolved Star Formation Patterns at 0.7 < z < 1.5
Stijn Wuyts, Natascha M. Forster Schreiber, Erica J. Nelson +20
We analyze the resolved stellar populations of 473 massive star-forming galaxies at 0.7 < z < 1.5, with multi-wavelength broad-band imaging from CANDELS and Halpha surface brightne…
The Pattern of CN, O, and Na Inhomogeneities on the Red Giant Branch of Messier 5
Graeme H. Smith, Payal N. Modi, Katherine M. Hamren
Data from the literature are used to explore the relation between 3883 CN band strength and the sodium and oxygen abundances of red giants in the globular cluster Messier 5. Alt…
A New Approach to Detailed Structural Decomposition from the SPLASH and PHAT Surveys: Kicked-up Disk Stars in the Andromeda Galaxy?
Claire E. Dorman, Lawrence M. Widrow, Puragra Guhathakurta +7
We characterize the bulge, disk, and halo subcomponents in the Andromeda galaxy (M31) over the radial range 4 < R_proj < 225 kpc. The cospatial nature of these subcomponents render…
The Progenitors of the Compact Early-Type Galaxies at High-Redshift
Christina C. Williams, Mauro Giavalisco, Paolo Cassata +19
We use GOODS and CANDELS images to identify progenitors of massive (log M > 10 Msun) compact "early-type" galaxies (ETGs) at z~1.6. Since merging and accretion increase the size of…
Carbon-enhanced Metal-poor Stars in SDSS/SEGUE. I. Carbon Abundance Estimation and Frequency of CEMP Stars
Young Sun Lee, Timothy C. Beers, Thomas Masseron +8
We describe a method for the determination of stellar [C/Fe] abundance ratios using low-resolution (R = 2000) stellar spectra from the SDSS and SEGUE. By means of a star-by-star co…
The SLUGGS Survey: The globular cluster systems of three early-type galaxies using wide-field imaging
Sreeja S. Kartha, Duncan A. Forbes, Lee R. Spitler +3
We present the results from a wide-field imaging study of globular cluster (GC) systems in three early-type galaxies. Combinations of Subaru/Suprime-Cam, CFHT/MegaCam and HST/WFPC2…
The SLUGGS Survey: Wide-field Stellar Kinematics of Early-type Galaxies
Jacob A. Arnold, Aaron J. Romanowsky, Jean P. Brodie +10
We present stellar kinematics of 22 nearby early-type galaxies (ETGs), based on two-dimensional (2D) absorption line stellar spectroscopy out to ~2-4 R_e (effective radii), as part…
A Budget and Accounting of Metals at z~0: Results from the COS-Halos Survey
Molly S. Peeples, Jessica K. Werk, Jason Tumlinson +4
We present a budget and accounting of metals in and around star-forming galaxies at . We combine empirically derived star formation histories with updated supernova and AG…
Towards a Unified Description of the Intergalactic Medium at Redshift z~2.5
J. Xavier Prochaska, Piero Madau, John M. O'Meara +1
We examine recent measurements of the z~2.5 intergalactic medium (IGM) which constrain the HI frequency distribution f(N) and the mean free path MFP to ionizing radiation. We argue…
