Radio-Continuum Spectra of Pulsars with Free-Free Thermal Absorption
Mario G. Abadi, Gabriela Castelletti, Namir E. Kassim
The radio continuum spectra of pulsars (PSRs) exhibit a wide variety of shapes, that are interpreted as pure and broken power laws, power laws with turnovers or cut-offs, and logar…

One size fits all: Insights on Extrinsic Thermal Absorption from Similarity of Supernova Remnant Radio Continuum Spectra
M. G. Abadi, G. Castelletti, L. Supan +2
Typically, integrated radio frequency continuum spectra of supernova remnants (SNRs) exhibit a power-law form due to their synchrotron emission. In numerous cases, these spectra sh…
