Abstract
Probing the evolution of galaxies through the neutral hydrogen window
has until recently been limited to studies of environmentally driven
evolution in the local universe. Detailed imaging studies of galaxies in
Virgo and volume limited surveys of clusters out to z = 0.08 show that
ram pressure stripping is one of the mechanisms that drives galaxy
evolution even at considerable distances from the dense cluster cores.
Hydrodynamical simulations show that indeed the effects of the ICM are
felt out to the virial radius due to the complex structure of the ICM.
Westerbork and Arecibo have begun to observe galaxies at cosmologically
interesting distances (z = 0.2). Soon the EVLA will be able to make a
complete census of all H I emission in cones of 40'×40' probing an
instantaneous velocity range from z = 0 to 0.53, with a resolution of a
few arcsec. If prime focus feeds were to be installed at the EVLA those
studies could easily be extended out to z = 1 in the coming decade,
making the EVLA a prime pathfinder for H I studies with the SKA.
