The Small Isolated Gas-rich Irregular Dwarf (SIGRID) Galaxy Sample: Description and First Results

Nicholls , David; Dopita, Michael; Jerjen, Helmut; Meurer, Gerhardt

Description

Using an optically unbiased selection process based on the HIPASS neutral hydrogen survey, we have selected a sample of 83 spatially isolated, gas-rich dwarf galaxies in the southern hemisphere with cz between 350 and 1650kms -1, and with R-band luminosities and H I masses less than that of the Small Magellanic Cloud. The sample is an important population of dwarf galaxies in the local universe, all with ongoing star formation, and most of which have no existing spectroscopic data. We are...[Show more]
