A Spectroscopic Galaxy Evolution Survey with the Hubble Space Telescope


 

October 8, 2015: The grism spectra from 3D-HST are now available!


This v4.1.5 release covers ALL FIVE 3D-HST/CANDELS fields: AEGIS, COSMOS, GOODS-N, GOODS-S and UDS. See Momcheva et al. (2015) for a full description of the data and methods. The v4.1.5 release includes:

  1. Extracted WFC3 2D and 1D spectra for ~250,000 objects

  2. Redshifts based on joint fits to the grism spectra and photometry for ~100,000 objects down to JH=26

  3. Emission line fits for to all major emission lines down to JH=26

  4. Best redshift catalog combining the spectroscopic, grism and photometric redshifts in the five fields

  5. Stellar masses, UV+IR star formation rates, rest-frame colors in 22 bands for the grism redshift and best redshift catalogs

  6. Extracted ACS 2D and 1D spectra for ~25,000 objects


Previous Releases:

The v3.0 release described in van Dokkum et al (2013), including deep HUDF spectra, can be found HERE.

The preliminary data release v0.5 (2012-04-15) accompanying the survey paper Brammer et al. (2012) can be found HERE.

Grism Spectra

Credit: When using the grism data products and derived parameters provided here, please cite Momcheva et al. (2015), Brammer et al. (2012) and include the following text: “This work is based on observations taken by the 3D-HST Treasury Program (GO 12177 and 12328) with the NASA/ESA HST, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS5-26555.”

Full documentation is available HERE. Regions files of the pointing layouts are available under Observations.


NOTE: Some of the downloads in this realease are very large, occasionally exceeding 50 GB! If your internet connection is consistently excellent (~100Mbpc), this download will take > 1 hour. We do realize that this is not the optimal way of distributing the dataset and are working on a database with an API interface. We hope to make it available soon.

Acknowledgements:

We are grateful to the many colleagues who have provided public data and catalogs in the five deep 3D-HST fields; high redshift galaxy science has thrived owing to this gracious mindset and the TACs and Observatory Directors who have encouraged this.

This work is based on observations made with the NASA/ESA Hubble Space Telescope, obtained from the MAST Data Archive at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555. Observations associated with the following GO and GTO programs were used: 12063, 12440, 12442, 12443, 12444, 12445, 12060, 12061, 12062, 12064 (PI: Faber); 12177 and 12328 (PI: van Dokkum); 12461 and 12099 (PI: Riess); 11600 (PI: Weiner); 9425 and 9583 (PI: Giavalisco); 12190 (PI: Koekemoer); 11359 and 11360 (PI: O’Connell); 11563 (PI: Illingworth).

The work, presented here, is based, in part, on data obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and NASA and was made possible by the generous financial support of the W. M. Keck Foundation. This work makes use of data obtained as part of the ESO/GOODS survey. Observations have been carried out using the Very Large Telescope at the ESO Paranal Observatory under Programme ID 168.A-0485. Based on observations made with ESO Telescopes at the La Silla or Paranal Observatories under programme number 168.A-0485. Based on data products from observations made with ESO Telescopes at the La Silla Paranal Observatory under ESO programme ID 179.A-2005 and on data products produced by TERAPIX and the Cambridge Astronomy Survey Unit on behalf of the UltraVISTA consortium. Based on observations obtained with MegaPrime/MegaCam, a joint project of CFHT and CEA/IRFU, at the Canada-France-Hawaii Telescope (CFHT) which is operated by the National Research Council (NRC) of Canada, the Institut National des Science de l’Univers of the Centre National de la Recherche Scientifique (CNRS) of France, and the University of Hawaii. This work is based in part on data products produced at Terapix available at the Canadian Astronomy Data Centre as part of the Canada-France-Hawaii Telescope Legacy Survey, a collaborative project of NRC and CNRS. This work makes use of data products produced at TERAPIX, the WIRDS consortium, and the Canadian Astronomy Data Centre. We thank H. Hildebrandt for providing the CARS-reduced CFHTLS images. This research has made use of the NASA/IPAC Infrared Science Archive, which is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration. This study makes use of data from COSMOS, a multiwavelength sky survey conducted with the Chandra, GALEX, Hubble, Keck, CFHT, MMT, Subaru, Palomar, Spitzer, VLA, and other telescopes and supported in part by the NSF, NASA, and the STFC. This study makes use of data from the NEWFIRM Medium-Band Survey, a multi-wavelength survey conducted with the NEWFIRM instrument at the KPNO, supported in part by the NSF and NASA. This paper uses data products produced by the OIR Telescope Data Center, supported by the Smithsonian Astrophysical Observatory. This work is based on observations made with the Spitzer Space Telescope, which is operated by the Jet Propulsion Laboratory, California Institute of Technology under contract with NASA.
