WebNov 4, 2016 · We discuss 6 GHz JVLA observations covering a volume-limited sample of 178 low-redshift optically selected quasi-stellar objects (QSOs).Our 176 radio detections fall into two clear categories: (1) about 20% are radio-loud QSOs (RLQs) with spectral luminosities of that are primarily generated in the active galactic nucleus (AGN) … Webby stars crossing AGN disks, and compare them to the observed properties of QPEs. We nd that when a star’s orbit is retrograde and has a low inclination (. 20 ) with respect to the AGN disk, the breakout emission from the bow shock can explain the observed duration (˘hours) and X-ray luminosity (˘few 1042 erg s 1) of QPEs. This model can ...
