    • 10 kpc Scale Seyfert Galaxy Outflow: HST/COS Observations of IRAS F22456-5125 

      Borguet, Benoit C. J.; Edmonds, Douglas; Arav, Nahum; Dunn, Jay; Kriss, Gerard A. (IOP Publishing Ltd., 2012-06)
      We present analysis of the UV spectrum of the low-z AGN IRAS F22456-5125 obtained with the Cosmic Origins Spectrograph on board the Hubble Space Telescope. The spectrum reveals six main kinematic components, spanning a ...
    • Physical Conditions in Quasar Outflows: Very Large Telescope Observations of QSO 2359-1241 

      Korista, K. T.; Bautista, M. A.; Arav, Nahum; Moe, Maxwell; Costantini, E.; Benn, C. (IOP PUBLISHING LTD, 2008-11)
      We analyze the physical conditions of the outflow seen in QSO 2359-1241 (NVSS J235953-124148), based on high-resolution spectroscopic VLT observations. This object was previously studied using Keck HIRES data. The main ...
    • Simultaneous XMM-Newton and HST-COS observation of 1H0419-577 The absorbing and emitting ionized gas 

      Di Gesu, L.; Arav, Nahum; Borguet, B.; Detmers, R. G.; Ebrero, J.; Edmonds, Douglas; Kaastra, J. S.; Piconcelli, E.; Verbunt, F.; Constantini, E. (EDP Sciences, 2013-08)
      In this paper we analyze the X-ray, UV, and optical data of the Seyfert 1.5 galaxy 1H0419-577 with the aim of detecting and studying an ionized-gas outflow. The source was observed simultaneously in the X-rays with XMM-Newton ...
    • XMM-Newton unveils the complex iron K alpha region of Mrk 279 

      Costantini, E.; Kaastra, J. S.; Korista, K.; Ebrero, J.; Arav, Nahum; Kriss, G.; Steenbrugge, K. C. (EDP Sciences, 2010-03-04)
      We present the results of a similar to 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 FeK alpha line may be equally well ...
