Radio Interferometric Observations of NGC 2146
Published online by Cambridge University Press: 13 May 2016
Extract
At 5 GHz, about 20 point sources were detected earlier by Glendenning & Kronberg (1986) in the central 800 pc of NGC 2146. Our observations with higher sensitivity and resolution made with MERLIN and the VLA confirms the detection of 18 sources, and resolves 7 of them (Fig.1). Additional 1.6-GHz MERLIN observations disclose 9 sources coincident in position with those detected at 5 GHz, which allows us to derive their spectral indices α51.6 (Sv ∼ να). Only 3 sources have indices (α < 0) consistent with synchrotron emission from supernova remnants or radio supernovae, while the others have very steep inverted spectra (α > 0).
