  The All-wavelength Extended Groth Strip International Survey (AEGIS) team
presents broad-band spectral energy distributions (SEDs), from X-ray to radio
wavelengths, for 71 galaxies spanning the redshift range 0.55-1.16 (<z>~0.7).
Galaxies with secure redshifts were selected from a small (22 arcminute-square)
sub-section of the Keck/DEIMOS galaxy redshift survey in the Extended Groth
Strip field that has also been targeted for deep panchromatic imaging by
Chandra (X-ray), GALEX (ultraviolet), Canada-France-Hawaii Telescope (optical),
Hubble Space Telescope (optical/near infrared), Palomar Observatory (near
infrared), Spitzer (mid/far infrared), and the Very Large Array (radio.) The
absolute magnitude of the typical galaxy in our sample is M_B=-19.82. The
ultraviolet to mid-infrared portion of their spectral energy distributions
(SEDs) are found to be bracketed by two stellar-only model SEDs: an early burst
followed by passive evolution and a constant star-formation rate since early
times; this suggests that few of these galaxies are undergoing major
starbursts. Approximately half the galaxies show a mid- to far-infrared excess
relative to the model SEDs, consistent with thermal emission from interstellar
dust. Two objects have power-law SEDs, indicating that they are dominated by
active galactic nuclei; both are detected in X-rays. The galaxies are grouped
by rest-frame color,quantitative optical morphology, and [OII] emission line
strength (possible indicator of star formation). On average, the panchromatic
SEDs of the galaxies, from the ultraviolet to the infrared, follow expected
trends: redder SEDs are associated with red U-B, early-type morphology, and low
[OII] emission, and vice versa for blue SEDs.
