Spectral Energy Distribution and Radio Halo of NGC 253 at Low Radio Frequencies

Spectral Energy Distribution and Radio Halo of NGC 253 at Low Radio Frequencies

We present new radio continuum observations of NGC 253 from the Murchison Widefield Array at frequencies between 76 and 227 MHz. We model the broadband radio spectral energy distribution for the total flux density of NGC 253 between 76 MHz and 11 GHz. The spectrum is best described as a sum of a cen...
