High Latitude Radio Emission in a Sample of Edge-On Spiral Galaxies
Judith A. Irwin, Jayanne English, Barkat Sorathia
We have mapped 16 edge-on galaxies at 20 cm using the VLA. For 5 galaxies, we could form spectral index, energy and magnetic field maps. We find that all but one galaxy show eviden…
Molecular Gas in the Perseus Cooling Flow Galaxy, NGC 1275
Terry Bridges, Judith Irwin
The central arcminute of the Perseus cooling flow galaxy, NGC 1275, has been mapped with the JCMT in 12CO(2-1) at 21 arcsec resolution, with detections out to at least 36 arcsec (1…
The Calibration of the HST Kuiper Belt Object Search: Setting the Record Straight
Anita L. Cochran, Harold F. Levison, Peter Tamblyn +2
The limiting magnitude of the HST data set used by Cochran et al. (1995) to detect small objects in the Kuiper belt is reevaluated, and the methods used are described in detail. It…
Relaxing and Virializing a Dark Matter Halo
Richard N. Henriksen, Lawrence M. Widrow
Navarro, Frenk, and White have suggested that the density profiles of simulated dark matter halos have a ``universal'' shape so that a given halo can be characterized by a single f…
Spectroscopy of Globular Clusters in NGC 4472
R. M. Sharples, S. E. Zepf, T. J. Bridges +4
Optical multi-slit spectra have been obtained for 47 globular clusters surrounding the brightest Virgo elliptical NGC 4472 (M49). Including data from the literature, we analyze vel…
