Hubble Space Telescope Observations of [O~III] Emission in Nearby QSO2s: Physical Properties of the Ionised Outflows
Anna Trindade Falcao, S. B. Kraemer, T. C. Fischer +14
We use Hubble Space Telescope (HST)/ Space Telescope Imaging Spectrograph (STIS) long-slit G430M and G750M spectra to analyse the extended [O~III] 5007A emission in a sample of twe…
Hubble Space Telescope Observations of Extended [O III] λ5007 Emission in Nearby QSO2s: New Constraints On AGN / Host Galaxy Interaction
Travis C. Fischer, S. B. Kraemer, H. R. Schmitt +15
We present a Hubble Space Telescope (HST) survey of extended [O III] λ5007 emission for a sample of 12 nearby (z < 0.12), luminous Type 2 quasars (QSO2s), which we use to measure t…
The Surprising Absence of Absorption in the Far-Ultraviolet Spectrum of Mrk 231
S. Veilleux, M. Trippe, F. Hamann +11
Mrk 231, the nearest (z = 0.0422) quasar, hosts both a galactic-scale wind and a nuclear-scale iron low-ionization broad absorption line (FeLoBAL) outflow. We recently obtained a f…
A Change in the Physical State of Carinae?
K. Davidson, J. C. Martin, R. M. Humphreys +8
During Car's spectroscopic event in mid-2003, the stellar wind's bright H and H emission lines temporarily had a distinctive shape unlike that reported on any previous oc…
The Origin of Fe II Emission in AGN
J. A. Baldwin, G. J. Ferland, K. T. Korista +2
We used a very large set of models of broad emission line (BEL) clouds in AGN to investigate the formation of the observed Fe II emission lines. We show that photoionized BEL cloud…
Implications of Quasar Black Hole Masses at High Redshifts
Matthias Dietrich, Fred Hamann
We investigated a sample of 15 luminous high-redshift quasars (3.3 < z < 5.1) to measure the mass of their super-massive black holes (SMBH) and compare, for the first time, results…
