Bulgeless Giant Galaxies Challenge Our Picture Of Galaxy Formation By Hierarchical Clustering Open
To better understand the prevalence of bulgeless galaxies in the nearby field, we dissect giant Sc-Scd galaxies with Hubble Space Telescope (HST) photometry and Hobby-Eberly Telescope (HET) spectroscopy. We use the HET High Resolution Spec…

Structure and Formation of Elliptical and Spheroidal Galaxies Open
New surface photometry of all known elliptical galaxies in the Virgo cluster is combined with published data to derive composite profiles of brightness, ellipticity, position angle, isophote shape, and color over large radius ranges. These…

STRUCTURE AND FORMATION OF cD GALAXIES: NGC 6166 IN ABELL 2199 Open
Hobby-Eberly Telescope (HET) spectroscopy is used to measure the velocity dispersion profile of the nearest prototypical cD galaxy, NGC 6166 in the cluster Abell 2199. We also present composite surface photometry from many telescopes. We c…
