ABSTRACT Characterizing spectral variability of radio sources is a technique that offers the ability to determine astrophysics intervening media, source structure, emission, and absorption processes. We present broadband (0.072–10 GHz) 15 peaked-spectrum (PS) with Australia Telescope Compact Array (ATCA) Murchison Widefield (MWA). These PS were observed quasi-contemporaneously ATCA MWA four six...
