WebSeyfert 1 galaxies, in addition, show a set of "broad lines" corresponding to velocities up to 1000 km/s, occurring only for the permitted lines, which indicates higher densities (10^9 electrons per cm^3). Osterbrook (1981) has introduced the following subclasses of Seyfert 1 galaxies, based on spectroscopic details: 1.5, 1.8 and 1.9. WebSeyfert 1 galaxies have both broad and narrow emission lines and are very luminous at UV and X-ray wavelengths. The broad emission lines are associated with allowed transitions in elements like hydrogen, helium, and iron (see the box below). Their width, as noted above, is caused by Doppler broadening that suggests the lines are produced in clouds with …

WebThe type I Seyfert galaxy NGC 3227 was observed by Suzaku six times in 2008, with intervals of ∼1 week and net exposures of ∼50 ks each. Among the six observations, the source varied by nearly an order of magnitude; it was brightest in the first observation with a 2-10 keV luminosity of 1.2 × 10{sup 42} erg s{sup –1}, while faintest in the fourth observation … b the leader
