The Cluster Velocity Dispersion of the Abell 2199 cD Halo of NGC 6166
Ralf Bender, John Kormendy, Mark E. Cornell +1
The Hobby-Eberly Telescope is used to measure the velocity dispersion profile of the nearest prototypical cD galaxy, NGC 6166 in cluster Abell 2199. We also present surface photome…
The Influence of Motion and Stress on Optical Fibers
Jeremy D. Murphy, Gary J. Hill, Phillip J. MacQueen +13
We report on extensive testing carried out on the optical fibers for the VIRUS instrument. The primary result of this work explores how 10+ years of simulated wear on a VIRUS fiber…
Design and construction progress of LRS2-B: a new low resolution integral field spectrograph for the Hobby-Eberly Telescope
Taylor S. Chonis, Hanshin Lee, Gary J. Hill +3
The upcoming Wide-Field Upgrade (WFU) has ushered in a new era of instrumentation for the Hobby-Eberly Telescope (HET). Here, we present the design, construction progress, and lab…
Supermassive black holes do not correlate with galaxy disks or pseudobulges
John Kormendy, R. Bender, M. E. Cornell
The masses of supermassive black holes are known to correlate with the properties of the bulge components of their host galaxies. In contrast, they appear not to correlate with gal…
HETDEX pilot survey for emission-line galaxies - I. Survey design, performance, and catalog
Joshua J. Adams, Guillermo A. Blanc, Gary J. Hill +23
We present a catalog of emission-line galaxies selected solely by their emission-line fluxes using a wide-field integral field spectrograph. This work is partially motivated as a p…
Bulgeless Giant Galaxies Challenge our Picture of Galaxy Formation by Hierarchical Clustering
John Kormendy, Niv Drory, Ralf Bender +1
We dissect giant Sc-Scd galaxies with Hubble Space Telescope photometry and Hobby-Eberly Telescope spectroscopy. We use HET's High Resolution Spectrograph (resolution = 15,000) to…
The Structure of the Accretion Disk in the ADC X-Ray Binary 4U 1822-371 at Optical and Ultraviolet Wavelengths
Amanda J. Bayless, Edward L. Robinson, Robert I. Hynes +2
The eclipsing low-mass X-ray binary 4U 1822-371 is the prototypical accretion disk corona (ADC) system. We have obtained new time-resolved UV spectroscopy of 4U 1822-371 with the A…
Structure and Formation of Elliptical and Spheroidal Galaxies
John Kormendy, David B. Fisher, Mark E. Cornell +1
New surface photometry of all known elliptical galaxies in the Virgo cluster is added to published data to derive composite profiles over large dynamic ranges. Sersic functions fit…
Ten Year Review of Queue Scheduling of the Hobby-Eberly Telescope
Matthew Shetrone, Mark E. Cornell, James R. Fowler +10
This paper presents a summary of the first 10 years of operating the Hobby-Eberly Telescope (HET) in queue mode. The scheduling can be quite complex but has worked effectively for…
Pseudobulges in the Disk Galaxies NGC 7690 and NGC 4593
John Kormendy, Mark E. Cornell, David L. Block +2
We present Ks-band surface photometry of NGC 7690 (Hubble type Sab) and NGC 4593 (SBb). We find that, in both galaxies, a major part of the "bulge" is as flat as the disk and has a…
Secular Evolution and the Growth of Pseudobulges in Disk Galaxies
John Kormendy, Mark E. Cornell
Galaxy evolution is in transition from an early universe dominated by hierarchical clustering to a future dominated by secular processes. These result from interactions involving c…
