POTENT Reconstruction from Mark III Velocities
A. Dekel, A. Eldar, T. Kolatt +5
We present an improved POTENT method for reconstructing the velocity and mass density fields from radial peculiar velocities, test it with mock catalogs, and apply it to the Mark I…
The peculiar motions of early-type galaxies in two distant regions - II. The spectroscopic data
Gary Wegner, Matthew Colless, R. P. Saglia +4
We present the spectroscopic data for the galaxies studied in the EFAR project, which is designed to measure the properties and peculiar motions of early-type galaxies in two dista…
The peculiar motions of early-type galaxies in two distant regions - V. The Mg-sigma relation, age and metallicity
Matthew Colless, David Burstein, Roger L. Davies +3
We examine the Mg-sigma relation for early-type galaxies in the EFAR sample and its dependence on cluster properties. A maximum likelihood fit gives global Mg-sigma relations of Mg…
UV Spectra, Line Indices of M31 Globular Clusters and E Galaxy Cores
J. M. Ponder, D. Burstein, R. W. O'Connell +6
Observations in integrated light (2200-4800 A, 8 to 11 A resolution, S/N > 20) of 4 M31 globular clusters and of the cores of six gE galaxies made with the HST/FOS are presented an…
The Mini AGN at the Center of the Elliptical Galaxy NGC 4552 with HST
Michele Cappellari, Alvio Renzini, Laura Greggio +4
The complex phenomenology shown by the UV-bright, variable spike first detected with the Hubble Space Telescope (HST) at the center of the otherwise normal galaxy NGC 4552 is furth…
Ring structure and warp of NGC5907 -- Interaction with dwarf galaxies
Zhaohui Shang, Zhongyuan Zheng, Elias Brinks +22
The edge-on, nearby spiral galaxy NGC5907 has long been used as the prototype of a ``non-interacting'' warped galaxy. We report here the discovery of two interactions with companio…
