EVN+e-MERLIN -Growing black holes or supernova factories in extremely op
Over the last few years it has become increasingly clear that some LIRGs host extremely compact obscured nuclei (CONs), however despite extensive studies from mm- to X-ray wavelengths the physical nature of these sources (compact star-formation, AGN or a hybrid of both) remains unclear. These so called 'CONs' are heavily obscured meaning that only very high resolution (VLBI) radio observations are able to probe their cores. Whilst we have acquired extensive high-resolution multi-wavelength data for each of these sources, only limited mas-scale radio imaging of these sources is available. In this proposal we request EVN+e-MERLIN observations to observe four nearby CONs, which form a sample of nearby exemplar CONs. This proposal aims to spatially resolve these compact nuclear regions and determine whether these CONs host compact starburst (akin to those observed in Arp299 or Arp220), AGN or both; and via combining e-MERLIN and EVN baselines connect the milliarcsecond and arcsecond scale emission to our multiwavelength analysis. This will providing the key, and much needed, information to determine the nature of the physical processes underway and the growth of the cores of these galaxies, and ultimately how these influence their galaxy hosts.
