The HST/ACS Coma Cluster Survey III. Structural Parameters of Galaxies using single-Sérsic Fits
Carlos Hoyos, Mark den Brok, Gijs Verdoes Kleijn +14
We present a catalogue of structural parameters for 8814 galaxies in the 25 fields of the HST/ACS Coma Treasury Survey. Parameters from Sérsic fits to the two-dimensional surface b…
The nature of proximate damped Lyman alpha systems
Sara L. Ellison, J. Xavier Prochaska, Joseph Hennawi +5
We present high resolution echelle spectra of 7 proximate damped Lyman alpha (PDLA) systems whose relative velocity separation from the background quasar is Delta V < 3000 km/s. Co…
The redshift and broad band spectral energy distribution of NRAO 150
J. A. Acosta-Pulido, I. Agudo, R. Barrena +3
Context. NRAO 150 is one of the brightest radio and mm AGN sources on the northern sky. It has been revealed as an interesting source where to study extreme relativistic jet phenom…
Distance to Multiple Kinematic Components of Quasar Outflows: VLT Observations of QSO 2359-1241 and SDSS J0318-0600
M. A. Bautista, J. P. Dunn, N. Arav +3
Using high resolution VLT spectra, we study the multi-component outflow systems of two quasars exhibiting intrinsic Fe II absorption (QSO 2359-1241 and SDSS J0318-0600). From the e…
Spectro-photometric close pairs in GOODS-S: major and minor companions of intermediate-mass galaxies
C. López-Sanjuan, M. Balcells, P. G. Pérez-González +3
(Abriged) Our goal here is to provide merger frequencies that encompass both major and minor mergers, derived from close pair statistics. We use B-band luminosity- and mass-limited…
The minor role of gas-rich major mergers in the rise of intermediate-mass early types at z <~ 1
C. López-Sanjuan, M. Balcells, P. G. Pérez-González +4
We study the evolution of galaxy structure since z ~ 1 to the present. From a GOODS-S multi-band catalog we define (blue) luminosity- and mass-weighted samples, limited by M_B <= -…
