The Phoenix Deep Survey: the clustering and the environment of Extremely Red Objects

A. Georgakakis, J. Afonso, A. M. Hopkins +3

In this paper we explore the clustering properties and the environment of the Extremely Red Objects (EROs; I-K>4mag) detected in a ~180arcmin^2 deep (Ks~20mag) Ks-band survey of a…

The Phoenix Deep Survey: spectroscopic catalog

J. Afonso, A. Georgakakis, C. Almeida +4

The Phoenix Deep Survey is a multi-wavelength survey based on deep 1.4 GHz radio imaging, reaching well into the sub-100 microJy level. One of the aims of this survey is to charact…

Bar Evolution Over the Last Eight Billion Years: A Constant Fraction of Strong Bars in GEMS

S. Jogee, F. D. Barazza, H. -W. Rix +25

One third of present-day spirals host optically visible strong bars that drive their dynamical evolution. However, the fundamental question of how bars evolve over cosmological tim…

The Phoenix Deep Survey: the radio properties of the hard X-ray selected sample

A. Georgakakis, A. M. Hopkins, J. Afonso +3

The radio properties of hard (2-8keV) X-ray selected sources are explored by combining a single 50ks XMM-Newton pointing with the ultra-deep and homogeneous Phoenix radio (1.4GHz)…

High Redshift Supernova Rates

Tomas Dahlen, Louis-Gregory Strolger, Adam G. Riess +10

We use a sample of 42 supernovae detected with the Advanced Camera for Surveys on-board the Hubble Space Telescope as part of the Great Observatories Origins Deep Survey to measure…

The Hubble Higher-Z Supernova Search: Supernovae to z=1.6 and Constraints on Type Ia Progenitor Models

L. -G. Strolger, A. G. Riess, T. Dahlen +33

We present results from the Hubble Higher-z Supernova Search, the first space-based open field survey for supernovae (SNe). In cooperation with the Great Observatories Origins Deep…
