Landing page for project EH041

VV114 (IC1623) is an infra-red luminous merging/interacting galaxy that harbors luminous double nuclei with a separation of about 6 kpc. These active nuclei provide an ideal laboratory for studying circum-nuclear starbursts phenomenon under extreme conditions triggered by interaction or collision of galaxies and also formation of active galactic nuclei (AGN) in the mid-phase of galaxy-galaxy merger process before gas dynamical motion is in equilibrium. In this program, we aim at finding a strong evidence for an AGN toward the more dominant eastern nucleus of VV114E by detecting a compact radio source with high brightness temperature and exploring an existence of a buried AGN or starburst nucleus or compact supernovae remnant sources like those observed in Arp 220 and NGC 6240 toward the western nucleus of VV114W. In order to reveal the properties of the two nuclei that are obscured by dust in nuclear region, we propose obtaining spectra from multi-frequency observations at 5 and 8.4 GHz. Thus, EVN will enable us to take unique advantage of high imaging sensitivity and spatial resolution for mapping out the double nuclei at 5/8.4 GHz.
