MHD Accretion-Disk Winds as X-ray Absorbers in AGNs
Keigo Fukumura, Demosthenes Kazanas, Ioannis Contopoulos +1
We present the 2D ionization structure of self-similar MHD winds off accretion disks around irradiated by a central X-ray source. Based on earlier observational clues and theoretic…
A Compton-thick Wind in the High Luminosity Quasar, PDS 456
J. N. Reeves, P. T. O'Brien, V. Braito +7
PDS 456 is a nearby (z=0.184), luminous (L_bol ~10^47 erg/s) type I quasar. A deep 190 ks Suzaku observation in February 2007 revealed the complex, broad band X-ray spectrum of PDS…
Narrow Radiative Recombination Continua: A Signature of Ions Crossing the Contact Discontinuity of Astrophysical Shocks
Raanan Nordon, Ehud Behar, Noam Soker +2
X-rays from planetary nebulae (PNs) are believed to originate from a shock driven into the fast stellar wind (v ~ 1000 km/s) as it collides with an earlier circumstellar slow wind…
