Tracing obscured galaxy build-up at high redshift using deep radio surveys
Stergios Amarantidis, Jose Afonso, Israel Matute +5
A fundamental question of extra-galactic astronomy that is yet to be fully understood, concerns the evolution of the star formation rate (SFR) and supermassive black hole (SMBH) ac…
The ATLAS 5.5 GHz Survey of the Extended Chandra Deep Field South: The Second Data Release
M. T. Huynh, M. E. Bell, A. M. Hopkins +2
We present a new image of the 5.5 GHz radio emission from the extended Chandra Deep Field South. Deep radio observations at 5.5 GHz were obtained in 2010 and presented in the first…
A new infrared color criterion for the selection of 0<z<7 AGN: application to deep fields and implications for JWST surveys
Hugo Messias, Jose M. Afonso, Mara Salvato +2
[Abridged] It is widely accepted that observations at mid-infrared (mid-IR) wavelengths enable the selection of galaxies with nuclear activity, which may not be revealed even in th…
The radio spectra of reddened 2MASS QSOs: evidence for young radio jets
A. Georgakakis, M. Grossi, J. Afonso +1
Multifrequency radio continuum observations (1.4-22 GHz) of a sample of reddened QSOs are presented. We find a high incidence (13/16) of radio spectral properties, such as low freq…
A multi-wavelength approach to the properties of Extremely Red Galaxy populations: I - Contribution to the Star Formation Rate density and AGN content
Hugo Messias, Jose Afonso, Andrew Hopkins +3
We present a multi-wavelength analysis of the properties of Extremely Red Galaxy (ERG) populations, selected in the GOODS-South/Chandra Deep Field South field. By using all the pho…
Investigating the Far-IR/Radio Correlation of Star Forming Galaxies to z=3
N. Seymour, M. Huynh, T. Dwelly +5
In order to examine the far-IR/radio correlation at high redshift we have studied the Spitzer 70um/far-infrared (far-IR) properties of sub-mJy radio sources from the 13^H XMM-Newto…
