Extragalactic radio sources with sharply inverted spectrum at metre wavelengths
Extragalactic radio sources with sharply inverted spectrum at metre wavelengths
We present the first results of a systematic search for the rare extragalactic radio sources showing an inverted (integrated) spectrum, with spectral index α ≥ +2.0, a previously unexplored spectral domain. The search is expected to yield strong candidates for α ≥ +2.5, for which the standard synchrotron self-absorption (characterized …
