Introduction WebJul 11, 2024 · These changes usually occur on timescales of years, but recently Gezari et al. reported on iPTF16bco, which showed a more rapid (≲1 yr) change of a LINER to a broad-line quasar. Several explanations of these dramatic changes have been proposed, including obscuration by passing dust or gas clouds and accretion rate changes (MacLeod et al. … daisy head mazy

WebJul 11, 2024 · One of the known changing-look quasars (CLQs), iPTF16bco (Gezari2024), was caught “turning-on" in the iPTF survey into a broad-line quasar from a low-ionization … WebCurrent time domain facilities are finding several hundreds of transient astronomical events a year. The discovery rate is expected to increase in the future as soon as new surveys such as the Zwicky Transient Facility (ZTF) and the Large Synoptic Sky Survey (LSST) come on line. At the present time, the rate at which transients are classified is approximately one … WebNuclear Outbursts in the Centers of Galaxies A dissertation presented to the faculty of the College of Arts and Sciences of Ohio University In daisy heavenly recordings
