Chandra Deep Field North
(CDFN, CDF-N, CDF-North)
(X-ray deep survey encompassing HDF region)
The Chandra Deep Field North (CDF-North, CDFN or CDF-N) is an
X-ray deep survey that includes the Hubble Deep Field (HDF) region
performed with Chandra X-ray Observatory (CXO) ACIS spectrometer.
CDF-N has been imaged with at least 20 days' exposure.
The Chandra Deep Field South (CDFS) was a similar effort in the southern hemisphere
which the GOODS-S followed up with images at other wavelengths.
