AEGIS-X - The Chandra AEGIS survey of the Extended Groth Strip

The Extended Groth Strip is a 0.5 deg2 region of sky being targeted for deep observations in all wavebands in order to study the evolution of galaxies. In the AO-3 phase, we obtained a 200ks Chandra observation of the original WFPC2 Groth Strip centred on the deep "Westphal" pointing. In AO-6, we were awarded an additional 7 x 200ks observations to cover the entire strip. The overarching goal of the program is to study the co-evolution of black holes and their host galaxies, by combining the Chandra data with the extraordinary array of observations at other wavelengths that have been obtained as part of the AEGIS collaboration. The multi-wavelength data includes the DEEP2 redshift survey (see also the UCSC DEEP page), HST/ACS observations, confusion limited Spitzer MIPS and IRAC infrared data, GALEX imaging and spectroscopy, an ultradeep VLA radio survey, and extensive ground-based imaging including the CFHTLS.

 

In July 2007 a further 1.8 Ms of Chandra ACIS-I time was awarded in AO-9 to observe three of the EGS fields (EGS-3, EGS-4 and EGS-5) to a total depth of 800 ks each. This very deep Chandra survey - called AEGIS-XD - overlaps with the ultra-deep Spitzer data from the FIDEL survey. AEGIS-XD is one of 5 deep fields being studied as part of the CANDELS survey.

 

The Chandra AO-6 observations were completed on 11th December 2005. Please see the survey status page for details of the current observations. Publications, source catalogues and reduced data are also available.
