The Kinematics in the Cores of Low Surface Brightness Galaxies
R. A. Swaters, M. A. W. Verheijen, M. A. Bershady +1
Systematic effects on HI and Halpha long-slit observations make a measurement of the inner slope of the dark matter density distribution difficult to determine. Halos with constant…
Tidal Remnants and Intergalactic HII Regions
T. Oosterloo, R. Morganti, E. M. Sadler +3
We report the discovery of two small intergalactic HII regions in the loose group of galaxies around the field elliptical NGC 1490. The HII regions are located at least 100 kpc fro…
Extinction in the Galaxy from surface brightnesses of ESO-LV galaxies: testing 'standard' extinction maps
Jacek Choloniewski, Edwin A. Valentijn
The relative extinction in the Galaxy computed with our new method (Choloniewski and Valentijn 2003, CV) is compared with three patterns: Schlegel, Finkbeiner and Davis (1998, SFD)…
Extinction in the Galaxy from surface brightnesses of ESO-LV galaxies: determination of A_R/A_B ratio
Jacek Choloniewski, Edwin. A. Valentijn
A new method for the determination of the extinction in our Galaxy is proposed. The method uses surface brightnesses of external galaxies in the B and R bands. The observational da…
The Opacity of Spiral Galaxies from Counts of Distant Background Galaxies
B. W. Holwerda, R. A. Gonzalez, R. J. Allen +1
We have applied the "Synthetic Field Method" on a sample of ~20 nearby galaxies in order to determine the opacity of their disks. We present preliminary results on the radial depen…
Stellar Abundances in Dwarf Irregular Galaxies
Kim Venn, Eline Tolstoy, Andreas Kaufer +1
Dwarf irregular galaxies appear to have undergone very slow chemical evolution since they have low nebular abundances, but have had ongoing star formation over the past 15 Gyr. The…
