Investigation of age and metallicity gradients and dust extinction in disc galaxies in the Hubble Deep Field
One caveat, Labbe notes, is that Hubble Deep Field
South is an extremely tiny patch of sky, taking up less than 1 percent of the area of the full moon.
Many astronomers have used the data compiled from that region of sky, known as the Hubble Deep Field
North, as a basis for further studies at a variety of wavelengths (SN: 1/20/96, p.
Richer of the University of British Columbia in Vancouver, and their colleagues compared the 1995 images of the Hubble Deep Field
North, the region viewed in exquisite detail by the Hubble Space Telescope, with those that the telescope took 2 years later.
The group used Chandra to examine a patch of sky that includes the Hubble Deep Field
, a region scrutinized in visible light by the Hubble Space Telescope.
Observations of the Hubble Deep Field
North and South, as the patches of sky are now called, have produced the sharpest images of galaxies ever made.
Richer of the University of British Columbia in Vancouver, and their colleagues used Hubble to reexamine the Hubble Deep Field
North 2 years after the telescope first imaged this region of sky (SN: 1/20/96, p.
Spectra taken last year by the Hubble instrument confirmed that the galaxy, located in a region adjacent to the Hubble Deep Field
North, has a redshift of 6.
It counted faint, faraway galaxies in the tiny patch of sky called the Hubble Deep Field
, which was scrutinized by the Hubble Space Telescope.
For 10 days in late 1995, the telescope's visible-light camera stared at the region, dubbed the Hubble Deep Field
, and revealed some 1,500 galaxies (SN: 1/20/96, p.
The galaxy lies in an extensively studied patch of sky known as the Hubble Deep Field
Barger of the University of Hawaii in Honolulu and her colleagues pointed the telescope at two small, seemingly blank regions of the sky, while Dunlop and his collaborators examined the Hubble Deep Field
, a patch of sky that has been studied extensively in visible light.
