Abell 0399-Abell 0401 radio bridge spectral index: the first
multifrequency detection
Abell 0399-Abell 0401 radio bridge spectral index: the first
multifrequency detection
Recent low-frequency radio observations at 140 MHz discovered a 3 Mpc-long bridge of diffuse emission connecting the galaxy clusters Abell 0399 and Abell 0401. We present follow-up observations at 60 MHz to constrain the spectral index of the bridge, which so far has only been detected at 140 and 144 …
