Supermassive Black Hole Winds in X-rays: SUBWAYS. II. HST UV spectroscopy of winds at intermediate redshifts
M. Mehdipour, G. A. Kriss, M. Brusa +35
We present a UV spectroscopic study of ionized outflows in 21 active galactic nuclei (AGN), observed with the HST. The targets of the SUBWAYS sample were selected with the aim to p…
Evolution of the Outflows in NGC 3516
Jay P. Dunn, Rozhin Parvaresh, S. B. Kraemer +1
We analyze the 2011 HST/COS spectrum of the Seyfert 1 galaxy NGC 3516, which demonstrates clear changes in one of the intrinsic absorption troughs (component 5), slight evidence of…
Determining the Locations of Dust Sources in FeLoBAL Quasars
Jay P. Dunn, Branden Wasik, Christin L. Holtzclaw +7
We conduct a spectroscopic search of quasars observed by the Sloan Digital Sky Survey (SDSS) with broad absorption line (BAL) troughs due to Mg II and troughs due to Fe II that sim…
Uncertainties in Atomic Data and Their Propagation Through Spectral Models. I
Manuel A. Bautista, Vanessa Fivet, Pascal Quinet +3
We present a method for computing uncertainties in spectral models, i.e. level populations, line emissivities, and emission line ratios, based upon the propagation of uncertainties…
BAL Outflow Contribution to AGN Feedback: Frequency of S iv Outflows in the SDSS
Jay P. Dunn, Nahum Arav, Kentaro Aoki +4
We present a study of Broad Absorption Line (BAL) quasar outflows that show S IV ?1063 and S IV* ?1073 troughs. The fractional abundance of S IV and C IV peak at similar value of t…
A 10 kpc Scale Seyfert Galaxy Outflow: HST/COS Observations of IRAS F22456-5125
Benoit Borguet, Doug Edmonds, Nahum Arav +2
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…
