Wide-field 1-2 GHz research on galaxy evolution -- synergies with multi-wavelength surveys

TL;DR

This paper discusses upcoming wide-field 1-2 GHz surveys and their synergy with multi-wavelength data, especially near-infrared and far-infrared surveys, to study galaxy evolution and high-redshift sources.

Contribution

It highlights the complementary nature of SKA-precursor radio surveys with VISTA near-infrared and Herschel far-infrared surveys for galaxy evolution research.

Findings

Synergies between SKA precursors and VISTA surveys for galaxy studies.

Potential of combining multi-wavelength data to identify high-redshift radio sources.

Framework for probing the epoch of reionization through multi-wavelength observations.

Abstract

In these proceedings I discuss various extragalactic surveys which will be undertaken over the next few years and which will be complementary to any HI and/or continuum surveys with the SKA-precursor telescopes. I concentrate on the near-infrared public surveys which will be undertaken with the Visible and Infrared Survey Telscope for Astronomy (VISTA), and in particular the VISTA Deep Extragalactic Observations (VIDEO) survey which will provide the ideal data set to combine with any deep SKA-precursor observations of the extragalactic sky. After highlighting the links that the SKA precursors have with the various VISTA surveys, I briefly describe two forthcoming Herschel surveys, Herschel-ATLAS survey and HerMES which have a large scientific overlap with the SKA-precursor telescopes. Finally, I present a case study in combining multi-wavelength data sets with radio-frequency surveys to find the highest redshift radio sources with the aim of probing the epoch of reionization.
