Beyond Hdf - Searching for Early Star Formation in the Infrared

نویسنده

  • D. THOMPSON
چکیده

Other papers in this volume describe some of the results which have come from the HDF data. I describe here several types of observations in the infrared which can take us beyond the redshifts probed by the HDF. Although I have split this paper into two main sections, one covering emission-line techniques and the other covering continuum-based techniques, it should be noted that all of these survey methods make use of some strong spectral feature in order to select galaxies out of a background of field galaxies at lower redshift.

Observations of the Hubble Deep Field with the Infrared Space Observatory V. Spectral energy distributions starburst models and star formation history

We have modelled the spectral energy distributions of the 13 HDF galaxies reliably detected by ISO. For 2 galaxies the emission detected by ISO is consistent with being starlight or the infrared ’cirrus’ in the galaxies. For the remaining 11 galaxies there is a clear mid-infrared excess, which we interpret as emission from dust associated with a strong starburst. 10 of these galaxies are spiral...

The Evolution of the Global Star Formation History as Measured from the Hubble Deep Field

The Hubble Deep Field (HDF) is the deepest set of multicolor optical photometric observations ever undertaken, and offers a valuable data set with which to study galaxy evolution. Combining the optical WFPC2 data with ground–based near–infrared photometry, we derive photometrically estimated redshifts for HDF galaxies with J < 23.5. We demonstrate that incorporating the near–infrared data reduc...

The Fir/radio Correlation of High Redshift Glaxies in the Region of the Hdf-n

The correlation between the far-infrared (FIR) and radio emission is well established for nearby star forming galaxies. Many applications, in particular the radio-to-submm spectral index redshift indicator, tacitly assume that the relation holds well beyond our local neighbourhood, to systems located at cosmological distances. In order to test this assumption I have constructed a sample of 22 H...

The Relative Star Formation Histories of Spiral Bulges and Elliptical Galaxies in the Hubble Deep Fields

Hierarchical galaxy formation models make specific predictions concerning the relative assembly rates and star formation histories of spiral bulges and field ellipticals. Independently of the cosmological model and initial power spectrum of fluctuations, at all epochs the stellar populations in spiral bulges should be older and redder than those in typical ellipticals selected at the same redsh...

An Accurate Position for Hdf 850.1: the Brightest Submillimeter Source in the Hubble Deep Field-north

We report a highly significant Submillimeter Array (SMA) detection of the prototypical submillimeter source HDF 850.1, which is the brightest submillimeter source in the Hubble Deep Field-North proper. The detection yields an extremely precise position of RA(2000)=12h 36m 51.99s and Dec(2000)=+62 12 25.83 with a 1σ positional uncertainty of 0.17. The position is consistent with the location of ...
