Aims: We present an analysis of a galaxy (SAGE1CJ053634.78-722658.5) at a redshift of 0.14 of which the infrared (IR) emission is entirely dominated by emission associated with the active galactic nucleus. Methods: We present the 5-37 ЮМm Spitzer/IRS spectrum and broad wavelength spectral energy distribution (SED) of SAGE1CJ053634.78-722658.5, an IR point-source detected by Spitzer/SAGE. ... We compare the source with models of emission from dusty tori around AGNs. ...

Next: M.E. Bailey, Director Up: Research Previous: C.S. Jeffery, Research Astronomer Contents . Dr Michael Smith has focused mainly on the earliest stages of stellar evolution: the processes leading to star formation from an initially unstable, collapsing cloud of gas, and the energetic outflows -- jets and winds -- associated with the formation and early evolution of protostars and pre-main-sequence stellar objects. ... Spectacular jets of molecules, however, betray its presence. ...

... We present the first results of an extensive near infrared survey of galactic and OH masers in high--luminosity star forming regions (SFR) aimed to see if there are near--infrared (NIR) sources directly associated with the masers. ... Although not in all sources there are high sensitivity--high resolution radio continuum observations, only few of the K--band/maser sources are closely associated with known ultracompact (UC) Hii regions. ...
