Abstract:
The evolution of galaxies is influenced by the environment in which
they reside. This effect should be strongest for the lowest-mass and
lowest-luminosity galaxies. To study dwarf galaxies in extremely low
density environments, we have compiled a deep catalogue of dwarf
galaxies in the nearby Lynx-Cancer void. This void hosts some of the
most metal-poor dwarfs known to date. It borders the Local Volume at
negative supergalactic Z(SGZ) coordinates and has a size of more
than 16Mpc. With a distance to its centre of only 18Mpc, it is close
enough to allow a search for the faintest dwarfs. Within the void 75
dwarf (-11.9>MB>-18.0) and four subluminous (-18.0>MB>-18.4)
galaxies have been identified. We present the parameters of the void
galaxies and a detailed analysis of the completeness of the catalogue
as a function of magnitude and surface brightness.

Note (1): The velocity Vdist:
* when marked by an asterisk (*) corresponds to D(Mpc)x73 where the
photometric (TRGB, Cepheids) distance D(Mpc) is available;
typical accuracy is ∼10%).
* otherwise, this is VLG+Vpec, where Vpec∼300km/s is a correction for
the peculiar velocity.
