Abstract: This project aims to image a subset of galaxies in the nearby Eridanus group in H I emission and in radio continuum using the GMRl'. The typical resolution of H I images will be ",1 kpc with a 30" sensitivity to H I mass of a few times 107 M0 • The rotation curves obtained using the H I velocity field together with the 2MASS magnitudes in the near infrared will be used to construct the 'lUlly-Fisher relation for this group. High resolution (sub-kpc) multi-frequency radio continuum images will be used to study star-formation rates, radio morphologies and spectral indices of Eridanus galaxies. About half of the galaxies have already been observed and further observations on some late type galaxies are proposed with the GMRI'. We present here the H I image and the rotation curve for a member of this group viz. NGC 1385.
