Mapping a Quasar Outflow from Parsec to Kiloparsec Scales: A Combined HST Absorption and VLT Emission Investigation
Mayank Sharma, Travis C. Fischer, Manuela Bischetti +4
Linking nuclear winds to galactic-scale outflows remains a major observational challenge in understanding the multiscale physics of active galactic nuclei feedback. Here we present…
Novel method to trace the dark matter density profile around supermassive black holes with AGN reverberation mapping
Mayank Sharma, Gonzalo Herrera, Nahum Arav +1
We propose a new method to determine the dark matter density profile in the vicinity of distant supermassive black holes (SMBH) using reverberation mapping (RM) measurements of act…
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…
Galactic-scale emission-line outflow from the radio-loud quasar 3C 191
Qinyuan Zhao, Luming Sun, Lu Shen +6
Quasar feedback is routinely invoked as an indispensable ingredient in galaxy formation models. Galactic outflows are a crucial agent of quasar feedback that frequently manifest th…
