ce-61: a Tidal Dwarf Galaxy in the Hercules cluster?
W. van Driel, P. -A. Duc, P. Amram +9
A candidate Tidal Dwarf Galaxy, ce-61, was identified in the merger system IC 1182 in the Hercules supercluster. The multi-wavelength data we obtained so far do not prove, however,…
Single Dish Calibration Techniques at Radio Wavelengths
K. O'Neil
Calibrating telescope data is one of the most important issues an observer faces. In this chapter we describe a number of the methods which are commonly used to calibrate radio tel…
The HI Content and Extent of Low Surface Brightness Galaxies - Could LSB Galaxies be Responsible for Damped Ly-alpha Absorption?
K. O'Neil
Low surface brightness galaxies, those galaxies with a central surface brightness at least one magnitude fainter than the night sky, are often not included in discussions of extrag…
Gas, Stars and Baryons in Low Surface Brightness Galaxies
K. O'Neil
Recent surveys have discovered hundreds of low surface brightness galaxies in the local (z < 0.1) Universe. Plots of the surface brightness distribution (the space density of galax…
The Morphology, Color, and Gas Content of Low Surface Brightness Galaxies
K. O'Neil
Recent surveys have discovered hundreds of low surface brightness galaxies, systems with central surface brightness fainter than 22.0 B mag arcsec^-2, in the local universe. Plots…
