PublicationThe extended nebulosity in the radio galaxy 3C 227
3C 227 (z = 0.085) exhibits one of the more spectacular extended nebulosities to be found among active galaxies at moderate redshifts. The gas can be traced to...

PublicationThe extended structure of the dwarf irregular galaxy Sagittarius
We present a detailed study of the stellar and H i structure of the dwarf irregular galaxy Sagittarius. We use new deep and wide field photometry to trace the...

PublicationThe Extensive Age Gradient of the Carina Dwarf Galaxy
The evolution of small systems such as dwarf spheroidal galaxies (dSphs) is likely to have been a balance between external environmental effects and internal...

PublicationThe extent of the Mg II absorbing circumgalactic medium of quasars
We investigate the extent and the properties of the Mg II cool, low-density absorbing gas located in the halo and in the circumgalactic environment of quasars...

PublicationThe Extinction by Dust in the Outer Parts of Spiral Galaxies
To investigate the distribution of dust in Sb and Sc galaxies we have analyzed near-infrared and optical surface photometry for an unbiased sample of 37...

PublicationThe Extinction Law in High-Redshift Galaxies
We estimate the dust extinction laws in two intermediate-redshift galaxies. The dust in the lens galaxy of LBQS 1009-0252, which has an estimated lens redshift...

PublicationThe extraordinarily bright optical afterglow of GRB 991208 and its host galaxy
Broad-band optical observations of the extraordinarily bright optical afterglow of the intense gamma-ray burst GRB 991208 started ~2.1 days after the event and...

PublicationThe Extreme CNO-enhanced Composition of the Primitive Iron-poor Dwarf Star J0815+4729
We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high...
