Radio and X-ray emission from disc winds in radio-quiet quasars
K. C. Steenbrugge, E. J. D. Jolley, Z. Kuncic +1
It has been proposed that the radio spectra of radio-quiet quasars is produced by free-free emission in the optically thin part of an accretion disc wind. An important observationa…
XMM-Newton RGS observation of the warm absorber in Mrk 279
J. Ebrero, E. Costantini, J. S. Kaastra +5
The Seyfert 1 galaxy Mrk 279 was observed by XMM-Newton in November 2005 in three consecutive orbits, showing significant short-scale variability (average soft band variation in fl…
XMM-Newton unveils the complex iron K alpha region of Mrk 279
E. Costantini, J. S. Kaastra, K. Korista +4
We present the results of a ~160 ks-long XMM-Newton observation of the Seyfert 1 galaxy Mrk 279. The spectrum shows evidence of both broad and narrow emission features. The Fe K al…
