Supermassive Black Holes from the SUNNS survey
Marc Sarzi, Hans-Walter Rix, Joseph C. Shields +5
We report three new accurate mass measurements for the supermassive black holes hosted by the early-type disk galaxies NGC2787, NGC4459 and NGC4596. The targets were selected from…
A Young Stellar Cluster in the Nucleus of NGC 4449
T. Boeker, R. P. van der Marel, L. Mazzuca +4
We have obtained 1-2 A resolution optical Echellette spectra of the nuclear star cluster in the nearby starburst galaxy NGC 4449. The light is clearly dominated by a very young (6-…
SuperMassive Black Holes in Bulges
Marc Sarzi, Hans-Walter Rix, Joseph C. Shields +5
We present spatially extended gas kinematics at parsec-scale resolution for the nuclear regions of four nearby disk galaxies, and model them as rotation of a gas disk in the joint…
FIRES at the VLT: Measuring the Rest-Frame V-Band Luminosity of Galaxies from z~3 to Now
Gregory Rudnick, Hans-Walter Rix, Marijn Franx
We present early results from the Faint InfraRed Extragalactic Survey (FIRES) at the VLT, the main goal of which is to study galaxy evolution in a deep, K-band selected sample. Wit…
Variability in LINERs
J. C. Shields, H. -W. Rix, D. H. McIntosh +6
A small number of LINERs have been seen to display variable H-alpha emission with a very broad, double-peaked profile. Recent observations with the Hubble Space Telescope indicate…
Double-Peaked Broad Emission Lines in NGC 4450 and Other LINERs
Luis C. Ho, Greg Rudnick, Hans-Walter Rix +5
Spectra taken with HST reveal that NGC 4450 emits Balmer emission lines with displaced double peaks and extremely high-velocity wings. This characteristic line profile, previously…
