Abstract:
We compared a sample of 121 compact extragalactic radio sources with a
matching comparison sample of extended sources (ECS). The former
consists of peaked-spectrum sources (PSS) and compact symmetric
objects (CSOs). We analysed composite spectra, diagnostic line
diagrams, spectral energy distributions, star formation indicators,
morphologies, and cluster environments. We found statistically
significant differences between the two samples.
Description:
We present the lists of the sources of the PSS-CSO sample as well as
the ECS sample. The lists contain the most important properties for
our study, in particular quantities derived from the analysis of the
optical spectra, photometric data from the far ultraviolet to the
mid-infrared, and images from the HST and the DESY Legacy Surveys.
