Schroeder (Univ. of Leicester), D. Burstein (Arizona State Univ.) and M.L. McCall (York Univ. | | Abstract: | Deep J, H and Ks photometry of the low Galactic latitude Norma cluster has been obtained with the 1.4-m Infrared Survey Facility (IRSF) and with SOFI on the NTT. Together with spectroscopy taken at the Anglo-Australian Observatory using 2dF, the near-infrared Fundamental Plane of the Norma cluster will be used to determine the distance to this cluster and to assess its location within the Great Attractor overdensity. Potential systematic uncertainties related to the determination of peculiar velocities in the Zone of Avoidance are discussed in some detail. In particular the effects (uncertainties, systematics and scatter) of extinction and star-crowding on the derived magnitudes at low latitudes are investigated in great detail. We present a first look at the emerging Ks-band Fundamental Plane of the Norma cluster. We expect an uncertainty of ~ 3% (~ 150 km/s at the distance of the Norma cluster) in our final Fundamental Plane distance estimate based on 76 galaxies. | | Source: | arXiv, astro-ph/0410725 | | Services: | Forum | Review | PDF | Favorites | |
