  1. Summary Black hole masses grow by ~10% from compact to

    extended sources Sample selection: ROGUE I (Kozieł-Wierzbowska et al. 2020 ApJS) No. There are ~5 times more compact than extended radio sources Do all compact radio sources become extended?

 debatable. It has been found that there are many more galaxies with compact radio emission (i.e. within its optical half-light radius) than hosting extended jets. We have used the state-of-the-art ROGUE I catalogue (Kozieł-Wierzbowska et al. 2020) of galaxies with radio cores to investigate whether all compact radio sources may become extended (the so-called youth scenario), or if most of them will stop emitting in radio before becoming extended (the frustration scenario; see e.g. Fanti et al. 1995, A&A, 302, 31). Using a set of toy models, we find that only ~2–4% of compact 
 become extended radio sources, and that their black hole masses increase by ~10% in this process. These results can help quantify the impact of radio jets on fuelling and/or quenching of star 
 formation in local galaxies. NRAO Karl G.

 extended source. • If the lifetime of a compact source is n times smaller than that of an extended one, 
 only one in every 5n compact will become extended. • Our sample is complete for host galaxies with stellar masses log M★ /M⨀ > 11.2. ROGUE I contains 32 616 radio sources associated with galaxies. All sources have been classified by eye. Left: examples of compact and extended radio sources*. Right: identification of radio AGNs.
 We define compact sources as radio AGNs where the radio emission comes from a region smaller than the host galaxy’s optical diameter. Radio AGNs are identified using a single criterion based on their WISE W3 band and radio luminosities (Kozieł- Wierzbowska in prep). Radio AGNs Compact Extended * We show here preliminary results using an earlier version of the catalogue. Toy models: we have randomly drawn a simulat- ed sample of compact sources from the observed extended sample. We compare the simulated to the observed compacts in M★ bins (i.e. assuming no host galaxy evolution). Free parameters: • f = by how much the black hole mass of an ex- tended source has grown since it was compact. • tCE/tE = the ratio of lifetimes of compact that will become extended (CE) to that of an 
 extended (E) source. To reproduce the observed compact sample, • f = 1.08–1.13, i.e. black hole masses increase by ~10%. • 0.01 < tCE/tE < 1.00 with likely values 0.1–0.2, i.e. a CE’s lifetime is 10–20% that of an E source. • Thus only 1 in every ~25 to 50 compact source will become 
 extended. p for Anderson–Darling and Mann–Whitney tests p ≥ 0.05 mean similar distributions
