Tracing PAHs and Warm Dust Emission in the Seyfert Galaxy NGC 1068
Justin H. Howell, Joseph M. Mazzarella, Ben H. P. Chan +16
We present a study of the nearby Seyfert galaxy NGC 1068 using mid- and far- infrared data acquired with the IRAC, IRS, and MIPS instruments aboard the Spitzer Space Telescope. The…
Hidden Galaxies Revealed
Greg Bothun, Chris Impey, Stacy McGaugh
In twenty years, low surface brightness (LSB) galaxies have evolved from being an idiosyncratic notion to being one of the major baryonic repositories in the Universe. The story of…
The Baryonic Tully-Fisher Relation
Stacy McGaugh, Jim Schombert, Greg Bothun +1
We explore the Tully-Fisher relation over five decades in stellar mass in galaxies with circular velocities ranging over 30 < Vc < 300 km/s. We find a clear break in the optical Tu…
Precision cosmological measurements: independent evidence for dark energy
Greg Bothun, Stephen D. H. Hsu, Brian Murray
Using recent precision measurements of cosmological paramters, we re-examine whether these observations alone, independent of type Ia supernova surveys, are sufficient to imply the…
NGC 2442: Tidal Encounters and the Evolution of Spiral Galaxies
Chris Mihos, Greg Bothun
Using imaging Fabry-Perot data, we study the star-forming properties and kinematics of the nearby barred spiral galaxy NGC 2442. The Halpha emission is very localized along the str…
Structural Characteristics and Stellar Composition of Low Surface Brightness Disk Galaxies
Stacy McGaugh, Greg Bothun
We present UBVI surface photometry of a sample of low surface brightness (LSB) disk galaxies. LSB disk galaxies are fairly well described as exponential disks with no preferred val…
The Morphology of Low Surface Brightness Disk Galaxies
Stacy McGaugh, Jim Schombert, Greg Bothun
We present and H images of a sample of Low Surface Brightness (LSB) disk galaxies. These galaxies are generally late types, if they can be sensibly classified at all. Ho…
Halpha Velocity Mapping of Ultraluminous Infrared Galaxies
Chris Mihos, Greg Bothun
We use imaging Fabry-Perot observations to explore the dynamical conditions in four southern ultraluminous (L_IR > 10^12 L_sun) infrared galaxies. These galaxies all show morpholog…
The Great Observatories All-Sky LIRG Survey: Comparison of Ultraviolet and Far-Infrared Properties
Justin H. Howell, Lee Armus, Joseph M. Mazzarella +21
The Great Observatories All-sky LIRG Survey (GOALS) consists of a complete sample of 202 Luminous Infrared Galaxies (LIRGs) selected from the IRAS Revised Bright Galaxy Sample (RBG…
