Science
The particular science goals that can be addressed with the VLA Frontier Field radio images include:
-
The relation between the level of star formation activity, radio spectral index, and starburst size of high-redshift galaxies.
-
The co-evolution of AGN and star-formation as a function of redshift through robust measurements of the brightness temperature, radio spectral index, and polarization of nuclear emission in galaxies.
-
The effects of the environment on the evolution of star formation and AGN growth within the galaxy clusters themselves.
-
Stacking analyses to improve detection limits for the highest redshift sources and confirm UV-radio star formation rate conversions as a function of redshift and luminosity.
- A detailed morphological study of the radio relics in MACSJ0717.5+3745 and MACSJ1149.5+2223. The former is the most powerful radio halo in the sky and is a textbook example of an extreme merging cluster.
