The HST/ACS Coma Cluster Survey - VII. Structure and Assembly of Massive Galaxies in the Center of the Coma Cluster
Tim Weinzirl, Shardha Jogee, Eyal Neistein +16
We constrain the assembly history of galaxies in the projected central 0.5 Mpc of the Coma cluster by performing structural decomposition on 69 massive (M_star >= 10^9 M_sun) galax…
Accretion Disk Temperatures of QSOs: Constraints from the Emission Lines
E. W. Bonning, G. A. Shields, A. C. Stevens +1
QSO emission-line spectra are compared to predictions based on theoretical ionizing continua of accretion disks. Observed line intensities do not show the expected trend of higher…
Fe II Emission in AGN: The Role of Total and Gas-Phase Iron Abundance
Gregory A. Shields, Randi R. Ludwig, Sarah Salviander
Active galactic nuclei (AGN) have Fe II emission from the broad line region (BLR) that differs greatly in strength from object to object. We examine the role of the total and gas-p…
A Search for Binary Active Galactic Nuclei: Double-Peaked [OIII] AGN in the Sloan Digital Sky Survey
Krista L. Smith, G. A. Shields, E. W. Bonning +3
We present AGN from the Sloan Digital Sky Survey (SDSS) having double-peaked profiles of [OIII] 5007,4959 and other narrow emission-lines, motivated by the prospect of finding cand…
