Spitzer observations of extended Lyman-alpha Clouds in the SSA22 field
T. M. A. Webb, T. Yamada, J. -S. Huang +5
We present the results of a Spitzer IRAC and MIPS 24 micron study of extended Lyman-alpha clouds (or Lyman-alpha Blobs, LABs) within the SSA22 filamentary structure at z = 3.09. We…
A Multiwavelength View of Star Formation in Interacting Galaxies in the Pavo Group
M. Machacek, M. L. N. Ashby, C. Jones +2
We combine Spitzer IRAC mid-infrared (MIR) and Chandra X-ray observations of the dominant galaxies NGC6872 and NGC6876 in the Pavo group with archival optical and HI data to study…
Near- and mid-infrared photometry of high-redshift 3CR sources
M. Haas, S. V. P. Willner, F. Heymann +5
Using the Spitzer Space Telescope, we have obtained 3.6--24 micron photometry of 38 radio galaxies and 24 quasars from the 3CR catalog at redshift 1<z<2.5. This 178 MHz-selected sa…
Galaxy Clusters in the IRAC Dark Field I: Growth of the red sequence
J. E. Krick, J. A. Surace, D. Thompson +4
Using three newly identified galaxy clusters at z~1 (photometric redshift) we measure the evolution of the galaxies within clusters from high redshift to the present day by studyin…
A point source survey of M31 with the Spitzer Space Telescope
Jeremy Mould, Pauline Barmby, Karl Gordon +5
We explore the stellar population of M31 in a Spitzer Space Telescope survey utilizing IRAC and MIPS observations. Red supergiants are the brightest objects seen in the infrared; t…
Spitzer IRAC Infrared Colours of Submillimetre-bright Galaxies
Min S. Yun, I. Aretxaga, M. L. N. Ashby +11
High-redshift submillimetre-bright galaxies identified by blank field surveys at millimetre and submillimetre wavelengths appear in the region of the IRAC colour-colour diagrams pr…
