VizieR Online Data Catalog: Extremely Isolated Galaxies. II. (Spector+, 2017)
Abstract
We have chosen the sample of EIGs using a simple isolation criterion: a galaxy is considered an EIG and is included in the sample if it has no known neighbours closer than a certain neighbour distance limit in 3D redshift space (200 or 300km/s as explained below) and if its redshift is in the range 2000<cz<7000km/s. No magnitude, HI mass or size limit was used in the selection of candidate neighbours.
Optical observations were performed using the 1-m (40 inch) telescope of the WO. EIGs were imaged using wide band Bessell U, B, V, R and I filters and a set of narrow-band rest-frame Hα filters for various redshifts. (10 data files).- Publication:
