NED Abstract

Copyright by Royal Astronomical Society. 1995MNRAS.277..857P Evolutionary models of the radio emission in compact starbursts Diego E. Perez-Olea and Luis Colina Space Telescope Science Institute, 3700 San Martin Drive, Baltimore, MD 21218, USA Departamento de Fisica Teorica C-XI, Universidad Autonoma de Madrid, 28019 Madrid, Spain Accepted 1995 June 16. Received 1995 May 22; in original form 1994 December 13 ABSTRACT We present the first complete set of evolutionary models developed to investigate the temporal evolution of the radio emission properties in compact starbursts. The constituents of the radio emission are the thermal free-free emission from the ionized gas, the non-thermal emission from young bright radio supernovae, and the nonthermal emission from old supernova remnants. Both instantaneous and continuous bursts are considered in a wide variety of models characterized by different metallicities and initial mass function (IMF) parameters, ie. IMF slope and mass limits. The outputs of the models have a direct applicability in the study of dusty star-forming environments like those present in starburst galaxies, in general. Also, the models ca be used for direct comparison with radio observations of ultraluminous infrared galaxies (ULIRG) to reveal the nature - active galactic nucleus (AGN) or nuclear starburst - of the energy source in the central regions of these galaxies. Key words: galaxies: active - galaxies: starburst - radio continuum: galaxies.
