AEGIS

All-wavelength Extended Groth Strip International Survey (AEGIS)

• Region:Extended Groth Strip (EGS: Ra=14h17m, DEc= 52d�30m�)

a Hubble Space Telescope (HST) survey consisting of 28 Wide-

Field Planetary Camera 2 (WFPC2) pointings carried out in 1994 by the WFPC team

low extinction, low Galactic/zodiacal infrared emission, and good

schedulability by space-based observatories

• comparsion with other deep fields

2x (for HST) to 4x (for Spitzer and Chandra) larger than the combined GOODS fields

The GEMS field covers a similar area to similar depths but was studied by the COMBO-

17 photometric redshift survey rather than a spectroscopic survey.

the GEMS F850LP imaging is too shallow to

study subcomponent colors for most galaxies.

Most AEGIS data sets cover ∼0.5–1 deg2, smaller than the 2 deg2 COSMOS field, but AEGIS is deeper

AEGIS is that deep HST/ACS imaging is available in two bands (F606W�F814W), in contrast to only F814W for the

COSMOS field;
