Active Galactic Nuclei in Groups and Clusters of Galaxies: Detection and Host Morphology
Timothy J. Arnold, Paul Martini, John S. Mulchaey +2
The incidence and properties of Active Galactic Nuclei (AGN) in the field, groups, and clusters can provide new information about how these objects are triggered and fueled, simila…
Feeding and Feedback in NGC 4151 from GEMINI Near Infrared Integral Field Spectroscopy
Ramiro D. Simoes Lopes, Thaisa Storchi-Bergmann, Rogemar A. Riffel +2
We discuss two-dimensional mapping of the near-infrared emission-line intensity distributions and kinematics of the narrow-line region (NLR) of NGC 4151, obtained with the Gemini N…
The Evolution of AGN in Groups and Clusters
Paul Martini
The evolution of AGN in groups and clusters provides important information about how their black holes grow, the extent to which galaxies and black holes coevolve in dense environm…
An Analysis of DES Cluster Simulations through the IMCAT and Shapelets Weak Lensing Pipelines
M. S. S. Gill, J. C. Young, J. P. Draskovic +8
We have run two completely independent weak lensing analysis pipelines on a set of realistic simulated images of a massive galaxy cluster with a singular isothermal sphere profile…
The Evolution of Active Galactic Nuclei in Clusters of Galaxies to Redshift 1.3
Paul Martini, Gregory R. Sivakoff, John S. Mulchaey
We have measured the luminous AGN population in a large sample of clusters of galaxies and find evidence for a substantial increase in the cluster AGN population from z~0.05 to z~1…
The Nuclear Outflows and Feedback in the Seyfert 2 Galaxy Markarian 573
K. Schlesinger, Richard W. Pogge, Paul Martini +2
We present a study of outflow and feedback in the well-known Seyfert 2 galaxy Markarian 573 using high angular resolution long-slit spectrophotometry obtained with the Hubble Space…
