The Acs Fornax Cluster Survey. I. Introduction to the Survey and Data Reduction Procedures
The Fornax Cluster is a conspicuous cluster of galaxies in the southern hemisphere and the second largest collection of early-type galaxies within <∼ 20 Mpc after the Virgo Cluster. In this paper, we present a brief introduction to the ACS Fornax Cluster Survey — a program to image, in the F475W (g475) and F850LP (z850) bandpasses, 43 early-type galaxies in Fornax using the Advanced Camera for ...
متن کاملThe ACS Virgo Cluster Survey . I . Introduction to the Survey
The Virgo Cluster is the dominant mass concentration in the Local Supercluster and the largest collection of elliptical and lenticular galaxies in the nearby universe. In this paper, we present an introduction to the ACS Virgo Cluster Survey: a program to image, in the F475W and F850LP bandpasses (≈ Sloan g and z), 100 early-type galaxies in the Virgo Cluster using the Advanced Camera for Surve...
متن کاملThe ACS Virgo Cluster Survey II . Data Reduction Procedures 1
The ACS Virgo Cluster Survey is a large program to carry out multi-color imaging of 100 early-type members of the Virgo Cluster using the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope. Deep F475W and F850LP images (≈ SDSS g and z) are being used to study the central regions of the program galaxies, their globular cluster systems, and the three-dimensional structure of Virgo it...
متن کاملThe Chandra Fornax Survey - I: The Cluster Environment
We present the first results of a deep Chandra survey of the inner ∼ 1 degree of the Fornax cluster of galaxies. Ten 50 ksec pointings were obtained in a mosaic centered on the giant elliptical galaxy NGC 1399 at the nominal cluster center. Emission and temperature maps of Fornax are presented, and an initial study of more than 700 detected X-ray point sources is made. Regions as small as 100pc...
