Dark matter inner slope and concentration in galaxies: from the Fornax dwarf to M87
G. A. Mamon, J. Chevalier, A. J. Romanowsky +1
We apply two new state-of-the-art methods that model the distribution of observed tracers in projected phase space to lift the mass / velocity anisotropy (VA) degeneracy and deduce…
The Evolution of the Galaxy Rest-Frame Ultraviolet Luminosity Function Over the First Two Billion Years
Steven L. Finkelstein, Russell E. Ryan, Casey Papovich +26
We present a robust measurement and analysis of the rest-frame ultraviolet (UV) luminosity function at z=4-8. We use deep Hubble Space Telescope imaging over the CANDELS/GOODS fiel…
CANDELS/GOODS-S, CDFS, ECDFS: Photometric Redshifts For Normal and for X-Ray-Detected Galaxies
Li-Ting Hsu, Mara Salvato, Kirpal Nandra +29
We present photometric redshifts and associated probability distributions for all detected sources in the Extended Chandra Deep Field South (ECDFS). The work makes use of the most…
Galaxy Zoo: CANDELS Barred Disks and Bar Fractions
B. D. Simmons, Thomas Melvin, Chris Lintott +39
The formation of bars in disk galaxies is a tracer of the dynamical maturity of the population. Previous studies have found that the incidence of bars in disks decreases from the l…
Non-parametric analysis of the rest-frame UV sizes and morphological disturbance amongst L* galaxies at 4<z<8
E. Curtis-Lake, R. J. McLure, J. S. Dunlop +12
We present the results of a study investigating the sizes and morphologies of redshift 4 < z < 8 galaxies in the CANDELS GOODS-S, HUDF and HUDF parallel fields. Based on non-parame…
The Panchromatic Hubble Andromeda Treasury. Progression of Large-Scale Star Formation across Space and Time in M31
Dimitrios A. Gouliermis, Lori C. Beerman, Luciana Bianchi +11
We investigate the clustering of early-type stars younger than 300 Myr on galactic scales in M31. Based on the stellar photometric catalogs of the Panchromatic Hubble Andromeda Tre…
The Panchromatic Hubble Andromeda Treasury V: Ages and Masses of the Year 1 Stellar Clusters
Morgan Fouesneau, L. Clifton Johnson, Daniel R. Weisz +13
We present ages and masses for 601 star clusters in M31 from the analysis of the six filter integrated light measurements from near ultraviolet to near infrared wavelengths, made a…
Globular clusters of NGC 3115 in the near-infrared. Demonstrating the correctness of two opposing scenarios
Michele Cantiello, John P. Blakeslee, Gabriella Raimondo +4
We combined new near-infrared VLT/HAWK-I data of the globular clusters (GCs) in the isolated edge-on S0 galaxy NGC 3115 with optical and spectroscopic ones taken from the literatur…
The First Hypervelocity Star from the LAMOST Survey
Zheng Zheng, Jeffrey L. Carlin, Timothy C. Beers +10
We report the first hypervelocity star (HVS) discovered from the LAMOST spectroscopic survey. It is a B-type star with a heliocentric radial velocity about 620 km/s, which projects…
Properties of Submillimeter Galaxies in the CANDELS GOODS-S Field
Tommy Wiklind, Christopher J. Conselice, Tomas Dahlen +29
We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with th…
Ultra compact dwarfs in the Perseus Cluster: UCD formation via tidal stripping
Samantha J. Penny, Duncan A. Forbes, Jay Strader +3
We present the results of a Keck/DEIMOS survey of Ultra Compact Dwarfs (UCDs) in the Perseus Cluster core. We confirm cluster membership for 14 UCDs, with radial velocities ~5300 k…
Bulge Growth and Quenching since z = 2.5 in CANDELS/3D-HST
Philipp Lang, Stijn Wuyts, Rachel S. Somerville +20
Exploiting the deep high-resolution imaging of all 5 CANDELS fields, and accurate redshift information provided by 3D-HST, we investigate the relation between structure and stellar…
Kinematic transitions and streams in galaxy halos
A. J. Romanowsky, J. A. Arnold, J. P. Brodie +7
The chemo-dynamics of galaxy halos beyond the Local Group may now be mapped out through the use of globular clusters and planetary nebulae as bright tracer objects, along with deep…
Stellar Kinematics and Structural Properties of Virgo Cluster Dwarf Early-Type Galaxies from the SMAKCED Project. I. Kinematically Decoupled Cores and Implications for Infallen Groups in Clusters
E. Toloba, P. Guhathakurta, G. van de Ven +12
We present evidence for kinematically decoupled cores (KDCs) in two dwarf early-type (dE) galaxies in the Virgo cluster, VCC 1183 and VCC 1453, studied as part of the SMAKCED stell…
Morphologies of z~0.7 AGN Host Galaxies in CANDELS: No trend of merger incidence with AGN luminosity
C. Villforth, F. Hamann, D. J. Rosario +24
The processes that trigger Active Galactic Nuclei (AGN) remain poorly understood. While lower luminosity AGN may be triggered by minor disturbances to the host galaxy, stronger dis…
The SLUGGS Survey: New evidence for a tidal interaction between the early type galaxies NGC 4365 and NGC 4342
Christina Blom, Duncan A. Forbes, Caroline Foster +2
We present new imaging and spectral data for globular clusters (GCs) around NGC 4365 and NGC 4342. NGC 4342 is a compact, X-ray luminous S0 galaxy with an unusually massive central…
