PublicationThe Soft X-ray and Narrow-line Emission of Mrk 573 on Kiloparsec Scales
We present a study of the circumnuclear region of the nearby Seyfert galaxy Mrk 573 using Chandra, XMM-Newton, and Hubble Space Telescope (HST) data. We have...

PublicationThe Space Density of Luminous Dusty Star-forming Galaxies at z > 4: SCUBA-2 and LABOCA Imaging of Ultrared Galaxies from Herschel-ATLAS
Until recently, only a handful of dusty, star-forming galaxies (DSFGs) were known at z > 4, most of them significantly amplified by gravitational lensing. Here...

PublicationThe Spatial and Age Distribution of Stellar Populations in DDO 190
The spatial distribution of stellar populations, the star formation history, and other properties of the dwarf irregular (dIrr) galaxy DDO 190 have been...

PublicationThe spatial distribution of coalescing neutron star binaries: implications for gamma-ray bursts
We find the distribution of coalescence times, birth rates, spatial velocities, and subsequent radial offsets of coalescing neutron stars (NSs) in various...

PublicationThe Spatial Distribution of the Far-Infrared Emission in NGC 253
We study the far-infrared emission properties of the nearby starburst galaxy NGC 253 based on IRAS maps and an ISOPHOT map at 180 μm. Based on the analysis of...
