Magellanic Cloud X-ray Sources: III. Completion of a ROSAT Survey
P. C. Schmidtke, A. P. Cowley, J. D. Crane +4
This paper concludes a series of three papers presenting ROSAT High-Resolution Imager (HRI) observations of unidentified Einstein and serendipitous ROSAT X-ray sources in the direc…
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 HST Key Project on the Extragalactic Distance Scale. XV. A Cepheid Distance to the Fornax Cluster and Its Implications
Barry F. Madore, Wendy L. Freedman, N. Silbermann +13
Using the Hubble Space Telescope (HST) 37 long-period Cepheid variables have been discovered in the Fornax Cluster spiral galaxy NGC 1365. The resulting V and I period-luminosity r…
QSO hosts and environments at z=0.9 to 4.2: JHK images with adaptive optics
J. B. Hutchings, D. Crampton, S. L. Morris +2
We have observed nine QSOs with redshifts 0.85 to 4.16 at near-IR wavelengths with the adaptive optics bonnette of the Canada-France-Hawaii telescope. Exposure times ranged from 15…
Deep Galaxy survey at 6.75 micron with the ISO satellite
H. Flores, F. Hammer, F. X. Désert +8
Deep 6.75um mid-IR ISOCAM observations were obtained of the Canada-France Redshift Survey (CFRS) 1415+52 field with the Infrared Space Observatory. The identification of the source…
HST observations of the Local Group dwarf galaxy Leo I
C. Gallart, W. L. Freedman, M. Mateo +10
We present deep HST F555W (V) and F814W (I) observations of a central field in the Local Group dwarf spheroidal (dSph) galaxy Leo I. The resulting color-magnitude diagram (CMD) rea…
