Abstract:
Recent sensitive wide-field radio surveys, such as the LOFAR Two Meter
Sky Survey (LoTSS), the LOFAR LBA Sky Survey (LoLSS), and the Very
Large Array Sky Survey (VLASS), enable the selection of statistically
large samples of peaked-spectrum (PS) sources. PS sources are radio
sources that have a peak in their radio continuum spectrum and are
observed to be compact. They are often considered to be the precursors
to large radio galaxies. We present a sample of 8032 gigahertz-peaked
spectrum (GPS) sources with spectral turnovers near 1400MHz, and a
sample of 506 megahertz-peaked spectrum (MPS) sources with turnovers
near 144MHz. Our GPS sample is over five times larger than any
previously known sample of PS sources. These large sample sizes allow
us to make a robust comparison between GPS sources and MPS sources,
such that we can investigate the differences between these types of
sources, and study their life-times. The shape of the source counts of
both samples match that of the general radio-loud active galactic
nuclei (AGN) samples, scaled down by a factor 44±2 for the MPS
sample, and a factor 28±1 for the GPS sample. Assuming no cosmo-
logical evolution, these offsets imply that both MPS and GPS sources
have shorter duration than general radio-loud AGN, with MPS sources
having an ~=1.6 times shorter lifespan than GPS sources. The shorter
duration of MPS sources relative to GPS sources can be explained by
the transition between GPS and MPS sources coinciding with the jet
breakout phase of PS sources, such that GPS sources traverse through
the surrounding medium at a lower speed than MPS sources. Such
evolution has been observed in simulations of PS source evolution.
