Vee P. Prasher,Matthew P. JanickiIn this contribution I will provide a brief summary of the history of searches for, and surveys of, galaxy groups. This will be split up into two separate parts, searches with and without galaxy redshift measurements. I will conclude with a more detailed look at a recent result from the 2 degree Field Galaxy Redshift Survey (2dFGRS).

https://doi.org/10.1007/978-3-030-55366-1We present here the first results from an ongoing spectroscopic survey of candidate compact groups selected in second Digitized Palomar Observatory Sky Survey, DPOSS II. The survey has been carried out at La Silla Observatory and 120 groups out of 261 possible candidates visible from the southern emisphere have been observed.

https://doi.org/10.1007/978-3-319-97313-5We present a photometric search for UCD candidates in the nearby galaxy group NGC 1023 (d=11 Mpc) – the poorest environment searched for UCDs yet –, based on wide field imaging with CFHT.

The Local Group Dwarfs ComparedI review the differences and similarities between the dwarf irregular and dwarf spheroidal galaxies in the Local Group. New observations are resolving the long-standing problem of the relationship between dwarf elliptical and dwarf irregular galaxies.

Stellar Metallicities and Ages in Leo I dSphWe present the first results of a spectroscopic study of Leo I dSph carried out using FORS2 at the ESO VLT, in which we derive metallicities for 78 red giant stars from the equivalent widths of calcium triplet lines.
