A Deep WSRT 1.4 GHz Radio Survey of the Spitzer Space Telescope FLSv Region
(2004-09)
The First Look Survey (FLS) is the first scientific product to emerge from the Spitzer Space Telescope. A small region of this field (the verification strip) has been imaged very deeply, permitting the detection of ...
Extragalactic Source Counts at 24 Microns in the Spitzer First Look Survey
(2004-09)
We present the Spitzer MIPS 24 micron source counts in the Extragalactic First Look Survey main, verification and ELAIS-N1 fields. Spitzer's increased sensitivity and efficiency in large areal coverage over previous infrared ...
Characterization of Extragalactic 24micron Sources in the Spitzer First Look Survey
(2004-09)
In this Letter, we present the initial characterization of extragalactic 24um sources in the Spitzer First Look Survey (FLS) by examining their counterparts at 8um and R-band. The color-color diagram of 24-to-8 vs. 24-to-0.7um ...
Taking measure of the Andromeda halo: a kinematic analysis of the giant stream surrounding M31
(2004-06)
We present a spectroscopic survey of the giant stellar stream found in the halo of the Andromeda galaxy. Taken with the DEIMOS multi-object spectrograph on the Keck2 telescope, these data display a narrow velocity dispersion ...
The tidal trail of NGC205?
(2004-07)
Using data taken as part of the Isaac Newton Telescope Wide Field Camera (INT WFC) survey of M31, we have identified an arc-like overdensity of blue, presumably metal-poor, red giant branch stars in the north-west quadrant ...
