SuperNova Acceleration Probe (SNAP): Investigating Photometric Redshift Optimization

Tomas Dahlen, Bahram Mobasher, Stephanie Jouvel +5

The aim of this paper is to investigate ways to optimize the accuracy of photometric redshifts for a SNAP like mission. We focus on how the accuracy of the photometric redshifts de…

The Faint End Slopes Of Galaxy Luminosity Functions In The COSMOS 2-Square Degree Field

Charles T. Liu, Peter Capak, Bahram Mobasher +5

We examine the faint-end slope of the rest-frame V-band luminosity function (LF), with respect to galaxy spectral type, of field galaxies with redshift z<0.5, using a sample of 80,…

The UDF05 Follow-up of the HUDF: I. The Faint-End Slope of the Lyman-Break Galaxy Population at z~5

P. A. Oesch, M. Stiavelli, C. M. Carollo +14

We present the UDF05 project, a HST Large Program of deep ACS (F606W, F775W, F850LP) and NICMOS (F110W, F160W) imaging of three fields, two of which coincide with the NICP1-4 NICMO…

Evidence for the Evolution of Young Early-Type Galaxies in the GOODS/CDF-S Field

Thomas H. Puzia, Bahram Mobasher, Paul Goudfrooij

We have developed an efficient photometric technique for identifying young early-type galaxy candidates using a combination of photometric redshifts, spectral-type classification,…

The effects of environment on morphological evolution between 0<z<1.2 in the COSMOS Survey

P. L. Capak, R. G. Abraham, R. S. Ellis +4

We explore the evolution of the morphology density relation using the COSMOS-ACS survey and previous cluster studies. The Gini parameter measured in a Petrosian aperture is found t…

Radio observations of the CDF-South: a possible link between radio emission and star formation in X-ray selected AGN

E. Rovilos, A. Georgakakis, I. Georgantopoulos +4

We explore the nature of the radio emission of X-ray selected AGN by combining deep radio (1.4GHz; 60micro-Jy) and X-ray data with multiwavelength (optical, mid-infrared) observati…
