DESI survey of S IV absorption outflows in quasars: Contribution to AGN feedback and comparison with [O III] emission outflows
Mayank Sharma, Nahum Arav, Maryam Dehghanian +4
Quasar outflows can play a crucial role in the evolution of their host galaxies through various feedback processes. This effect is expected to be particularly important when the un…
Quasar absorption outflows on galactic scales: Insights from DESI
Maryam Dehghanian, Nahum Arav, Mayank Sharma +4
Absorption outflows in quasars play an important role in understanding active galactic nuclei (AGN) feedback and their influence on galaxy evolution. The unprecedented spectral dat…
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…
An energetic absorption outflow in QSO J1402+2330: Analysis of DESI observations
M. Dehghanian, N. Arav, M. Sharma +3
Context. Quasar outflows play a significant role in the active galactic nucleus (AGN) feedback, impacting the interstellar medium and potentially influencing galaxy evolution. Char…
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…
