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…
