Broadband spectral modeling of the extreme gigahertz-peaked spectrum radio source PKS B0008-421

Broadband spectral modeling of the extreme gigahertz-peaked spectrum radio source PKS B0008-421

We present broadband observations and spectral modeling of PKS B0008-421 and identify it as an extreme gigahertz-peaked spectrum (GPS) source. PKS B0008-421 is characterized by the steepest known spectral slope below the turnover, close to the theoretical limit of synchrotron self-absorption, and th...
