The distance of quasar outflows from the central source: The first consistent values from emission and absorption determinations
Mayank Sharma, Nahum Arav, Qinyuan Zhao +8
Measuring the distance of quasar outflows from the central source () is essential for determining their importance for AGN feedback. There are two methods to measure : 1) A d…
Physical characterization of the FeLoBAL outflow in SDSS J0932+0840: Analysis of VLT/UVES observations
Mayank Sharma, Nahum Arav, Kirk T. Korista +5
Context: The study of quasar outflows is essential in understanding the connection between active galactic nuclei (AGN) and their host galaxies. We analyze the VLT/UVES spectrum of…
Determining the absolute chemical abundance of nitrogen and sulfur in the quasar outflow of 3C298
Maryam Dehghanian, Nahum Arav, Mayank Sharma +2
Context. Quasar outflows are key players in the feedback processes that influence the evolution of galaxies and the intergalactic medium. The chemical abundance of these outflows p…
AGN STORM 2: VIII. Investigating the Narrow Absorption Lines in Mrk 817 Using HST-COS Observations
Maryam Dehghanian, Nahum Arav, Gerard A. Kriss +39
We observed the Seyfert 1 galaxy Mrk817 during an intensive multi-wavelength reverberation mapping campaign for 16 months. Here, we examine the behavior of narrow UV absorption lin…
Narrow absorption line Outflow in Seyfert 1 galaxy J1429+4518: Outflow's distance from the central source and its energetics
Maryam Dehghanian, Nahum Arav, Doyee Byun +2
In the HST/COS spectrum of the Seyfert 1 galaxy 2MASX J14292507+4518318, we have identified a narrow absorption line (NAL) outflow system with a velocity of -151 km s This o…
Extreme FeLoBAL Outflow in the VLT/UVES Spectrum of Quasar SDSS J1321-0041
Doyee Byun, Nahum Arav, Mayank Sharma +2
Context. Quasar outflows are often analyzed to determine their ability to contribute to active galactic nucleus (AGN) feedback. We identified a broad absorption line (BAL) outflow…
BAL Outflow in Quasar B0254-3327B: Analysis and Comparison with Other Extreme UV Outflows
Doyee Byun, Nahum Arav, Maryam Dehghanian +2
We have identified a broad absorption line (BAL) outflow in the HST/STIS spectrum of the quasar QSO B0254-3327B at velocity $v=-3200\text{ km s$^{-1}$}$. The outflow has absorption…
High Mass Flow Rate in a BAL Outflow of Quasar SDSS J1130+0411
Andrew Walker, Nahum Arav, Doyee Byun
We present the analysis of the absorption troughs of six outflows observed in quasar SDSS J1130+0411 () with radial velocities ranging from to km…
VLT/UVES Observation of the SDSS J2357-0048 Outflow
Doyee Byun, Nahum Arav, Patrick B. Hall
We found a broad absorption line (BAL) outflow in the VLT/UVES spectrum of the quasar SDSS J235702.54-004824.0, in which we identified four subcomponents. We measured the column de…
VLT/UVES Observation of the Outflow in Quasar SDSS J1439-0106
Doyee Byun, Nahum Arav, Andrew Walker
We analyze the VLT/UVES spectrum of the quasar SDSS J143907.5-010616.7, retrieved from the UVES Spectral Quasar Absorption Database. We identify two outflow systems in the spectrum…
The Farthest Quasar Mini-BAL Outflow from its Central Source: VLT/UVES Observation of SDSSJ0242+0049
Doyee Byun, Nahum Arav, Patrick B. Hall
We analyze VLT/UVES observations of the quasar SDSS J024221.87+004912.6. We identify four absorption outflow systems: a CIV BAL at , and three n…
