X-shaped radio sources as parent population of core-dominated triple blazars
Andrzej Marecki
There are a number of theories explaining the nature of the so-called X-shaped radio sources. According to one of them, an X-shaped source is indeed a cross whose one arm is associ…
Are 3C249.1 and 3C334 restarted quasars?
Andrzej Marecki
This Research Note follows up a Letter in which I posit that J1211+743 is a restarted radio source. This means that its structure, where the jet points to the relic lobe, is only a…
More evidence for extinction of activity in galaxies
Andrzej Marecki, Bartlomiej Swoboda
This Research Note amends an article in which we showed that radio-loud quasars can become radio-quiet. Exploring the analogy between galactic nuclei and X-ray binaries (XRB), we p…
Evidence of a double-double morphology in B0818+214
Andrzej Marecki, Marek Szablewski
The so-called double-double structure in radio sources is the most conspicuous signature of their restarted activity. Observations indicate that in the majority of double-double ra…
