GOODS Project Status and Updates

10 April 2010: Extremely deep 1.4 GHz VLA observations of GOODS-North
Glenn Morrison (IfA, U. Hawaii; CFHT) and colleagues have released extremely deep VLA 1.4 GHz observations of the GOODS-North field. 165 hours of VLA observations in the A, B, C and D configurations were combined to produce an image with RMS noise of 3.9 microJy per beam at phase center, one of the deepest radio data observations ever made. The observations are described and source catalogs are presented in
Morrison et al. 2010, ApJ, 188, 178. FITS data files are available at data release.

02 March 2010: VLT/ISAAC imaging of the Hubble Ultradeep Field
The GOODS ESO team has released
extremely deep K-band images of the Hubble Ultradeep Field. The data products combine deep VLT/ISAAC K-band imaging obtained by Ivo Labbe and collaborators with previous GOODS ISAAC K-band imaging in this area. The final image has a total exposure time of 25.3 hours, with a net PSF FWHM of 0.36 arcsec, and reaches a median 5-sigma point source limiting magnitude of 25.6, 0.67 mag deeper than the GOODS ISAAC K-band data alone. The image products are available from the ESO Archive.

19 January 2010: Hubble Space Telescope Multicycle Treasury Program for GOODS and other fields
Two proposals for very large, multi-year programs of Hubble Space Telescope observations of GOODS and other cosmological survey fields have been jointly approved, with a total observing time of 902 orbits. The project will survey the rest-frame optical wavelength properties of galaxies at 1.5 < z < 3, make a census of star-forming galaxies at 6 < z < 9, and will detect type Ia supernovae at z > 1.5 for cosmological studies. Drs. Sandra Faber (University of California Santa Cruz) and Harry Ferguson (STScI) are the co-PIs for the merged program, which will use the Wide Field Camera 3 infrared channel (WFC3-IR), as well as the Advanced Camera for Surveys (ACS) optical imager, to obtain data in five fields: GOODS-North and -South, the Extended Groth Strip (EGS), the UK Infrared Deep Sky Survey (UKIDSS) Ultra-Deep Survey (UDS) field, and the Cosmic Evolution Survey (COSMOS) field. A total solid angle of approximately 900 square arcminutes will be surveyed with deep near-infrared J- and H-band WFC3-IR imaging. Additionally, about 40% of the GOODS area will be imaged to substantially deeper limits, and in the Y-band (1.05 micron) filter as well, enabling the identification and study of very high redshift galaxies. GOODS-North is in the HST Continuous Viewing Zone, enabling ultraviolet observations in that field with the WFC3-UVIS channel. Distant supernovae detected in the WFC3-IR imaging will be followed up with a combination of grism spectroscopy and photometric monitoring of their light curves.

A temporary web site briefly describes the project and will be expanded in the future. In particular, a detailed abstract gives more information about the fields, filters and exposure times. This same abstact, along with those of two other approved Multicycle Treasury Programs, is also available at the STScI MCTP web site.

29 December 2009: Gemini / FLAMINGOS-2 infrared spectroscopic survey of GOODS-South
Mark Dickinson (NOAO) and Anthony Gonzalez (Univ. Florida) are co-PIs for an NOAO Survey Program to obtain near-infrared spectra of 1000 galaxies in GOODS-South with the
FLAMINGOS-2 multi-object spectrograph (see also the UF F2 web site) at the Gemini-South observatory. The NOAO Survey Program will be supplemented by additional guaranteed time granted to the FLAMINGOS-2 principal investigator, Steve Eikenberry (UF). This will be the first large-scale near-infrared spectroscopic survey of high redshift galaxies and is designed to measure redshifts and nebular line diagnostics for galaxies and AGN primarily at 1.4 < z < 2.5. The observations will be carried out over two years in 2010 and 2011.

22 December 2009: First Herschel observations of the GOODS fields.
Early observations from the Herschel Space Observatory were presented at a workshop in Madrid, Spain on 17-18 December 2009. The GOODS-North field was observed during Science Demonstration Phase observations by both the PACS and SPIRE instrument teams as part of their guaranteed time programs.
Presentations from the workshop include images and early scientific results for GOODS-N:

The GOODS-Herschel Open Time Key Program, led by David Elbaz (CEA/Saclay), will observe GOODS-N in 2010 with substantially longer exposure times using both instruments, and will also obtain an ultradeep observation with PACS at 100 and 160 microns covering approximately 42 square arcminutes in GOODS-South.

1 November 2009: The CXC director's office has announced plans for an additional 2 Msec of Chandra exposure time on the Chandra Deep Field South (CDF-S, including GOODS-S), which will increase the total exposure time to 4 Msec. Observations are likely to be carried out in two parts, in Spring 2010 and 2011, respectively.

The new data increase the exposure time in the F850LP band by factors of 2.3 and 1.7 in GOODS-N and -S, respectively, with more modest increments in F775W and F606W as well. Catalogs (r2.0z) are also available, as well as a new ACS cutout image server.

18 February 2008: First public release of VLT/VIMOS spectroscopy for GOODS-S.

16 January 2008: GOODS-Herschel Open Time Key Program accepted!
David Elbaz (CEA/Saclay) is PI for an open time Key Program of far-infrared obserations of the GOODS fields using the Herschel Space Observatory, whose launch is planned for later in 2008. The program has been awarded 362.6 hours of Herschel observing time, and consists of the following components:

The "superdeep" observations of GOODS-S match the exposure times planned for the equivalent program on GOODS-South in the Guaranteed Time Key Programs (PACS and HerMES). The "ultradeep" observations will cover a portion of GOODS-S with PACS with the longest exposure times and faintest flux limits planned for the observatory.
