| dc.description.abstract | MHONGOOSE is a deep survey of the neutral hydrogen distribution in a representative sample
of 30 nearby disk and dwarf galaxies with H

masses from

to
∼

log
(

. Our extremely deep observations, down to H

column density limits of well below

— or a few hundred times fainter than the typical H
I
disks in galaxies — will directly
detect the effects of cold accretion from the intergalactic medium and the links with the cosmic
web. These observations will be the first ever to probe the very low-column density neutral gas in
galaxies at these high resolutions.
Combination with data at other wavelengths, most of it already available, will enable accurate
modeling of the properties and evolution of the mass components in these galaxies and link these
with the effects of environment, dark matter distribution, and other fundamental properties such
as halo mass and angular momentum.
MHONGOOSE can already start addressing some of the SKA-1 science goals and will provide a
comprehensive inventory of the processes driving the transformation and evolution of galaxies in
the nearby universe at high resolution and over 5 orders of magnitude in column density. It will
be a Nearby Galaxies Legacy Survey that will be unsurpassed until the advent of the SKA, and
can serve as a highly visible, lasting statement of MeerKAT’s capabilities | en_US |
