Herschel observations and a model for IRAS 08572+3915: a candidate for the most luminous infrared galaxy in the local (z < 0.2) Universe
A. Efstathiou, C. Pearson, D. Farrah +17
We present Herschel photometry and spectroscopy, carried out as part of the Herschel ULIRG survey (HERUS), and a model for the infrared to submillimetre emission of the ultralumino…
Hot-Dust (690K) Luminosity Density and its Evolution in the last 7.5Gyr
Hugo Messias, Bahram Mobasher, José Manuel Afonso
[Abridged] We study the contribution of hot-dust to the luminosity density of galaxies and its evolution with cosmic time. Using the Spitzer-IRAC data in the COSMOS field, we estim…
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…
LOFAR and APERTIF surveys of the radio sky: probing shocks and magnetic fields in galaxy clusters
Huub Rottgering, Jose Afonso, Peter Barthel +32
At very low frequencies, the new pan-European radio telescope LOFAR is opening the last unexplored window of the electromagnetic spectrum for astrophysical studies. The revolutiona…
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…
The extraordinary mid-infrared spectral properties of FeLoBAL Quasars
D. Farrah, T. Urrutia, M. Lacy +7
We present mid-infrared spectra of six FeLoBAL QSOs at 1<z<1.8, taken with the Spitzer space telescope. The spectra span a range of shapes, from hot dust dominated AGN with silicat…
