The Sizes and Kinematic Structure of Absorption Systems Towards the Lensed Quasar APM08279+5255
Sara L. Ellison, Rodrigo Ibata, Max Pettini +4
We have obtained spatially resolved spectra of the z=3.911 triply imaged QSO APM08279+5255 using the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Telescope…
The Structure of High Redshift Galactic Halos
Sara L. Ellison, Rodrigo Ibata, Max Pettini +4
Observations of multiple or lensed QSOs at high redshift can be used to probe transverse structure in intervening absorption systems. Here we present results obtained from STIS spe…
Outflowing material in the zem = 4.92 BAL QSO SDSS~J160501.21-011220.0
Neeraj Gupta, Raghunathan Srianand, Patrick Petitjean +1
We present the analysis of two BALs seen in the spectrum of the QSO SDSS J160501.21-011220.0. Our UVES spectrum shows two well detached BALs at z(abs)= 4.685 and 4.855. The system…
