A relativistic inflow candidate in a quasar at cosmic noon

Yerong Xu, Xiurui Zhao, Elena Bertola +14

Cosmic noon () marks the peak epoch of cosmic star formation and black hole accretion activity, where strong accretion and outflows are expected. We report two candidate ab…

First detection of ultra-fast outflows in a quiescent galaxy

Yerong Xu, Malgorzata Siudek, Victor Rodríguez Morales +7

Outflows in active galactic nuclei (AGN) are recognized as a fundamental mechanism driving the co-evolution of supermassive black holes (SMBHs) and their host galaxies. Although po…

Footprints in the Wind: Probing X-ray Outflows in NGC 7469 using Near-Infrared Emission Lines

Léa M. Feuillet, Steve Kraemer, Anna Trindade Falcão +7

AGN winds play an important role in the co-evolution of supermassive black holes and their host galaxies, yet their driving mechanisms and impact on star formation remain subjects…

Core Revelations: the Star Formation and AGN Connection at the Heart of NGC 7469

Léa M. Feuillet, Steve Kraemer, Marcio B. Meléndez +4

We investigate the star formation-AGN connection in the Seyfert 1 NGC 7469 using James Webb Space Telescope (JWST) mid-infrared spectroscopic integral field unit (IFU) data. We use…

Star Formation Rates in [Ne V] 3426 Å Selected Active Galactic Nuclei: Evidence for a Decrease along the Main Sequence?

Léa Feuillet, Marcio Meléndez, Steve Kraemer +3

Studying the behavior along the galaxy main sequence is key in furthering our understanding of the possible connection between AGN activity and star formation. We select a sample o…

Classifying Intermediate Redshift Galaxies in SDSS: Alternative Diagnostic Diagrams

Léa Feuillet, Marcio Meléndez, Steve Kraemer +3

We select a sample of 1,437 active galactic nuclei (AGN) from the catalog of the Sloan Digital Sky Survey (SDSS) galaxy properties from the Portsmouth group by detection of the hig…
