The MUSE Hubble Ultra Deep Field Survey: III. Testing photometric redshifts to 30th magnitude
, 2017 International audienceWe tested the performance of photometric redshifts for galaxies in the Hubble Ultra Deep field down to 30th magnitude. We compared photometric redshift estimates from three spectral fitting codes from the literature (EAZY, BPZ and ...

Estimation of redshifts from early galaxies [Elektronisk resurs]
, 2007 Dating early galaxies is a current technical, empirical and theoretical problem. Progress has been made recently calculating these dates using the observed redshift, z, alone.

The peculiar motions of early-type galaxies in two distant regions - II. The spectroscopic data
, 1999 We present the spectroscopic data for the galaxies studied in the EFAR project, which is designed to measure the properties and peculiar motions of early-type galaxies in two distant regions.

Host Galaxies as Gamma-Ray Burst Distance Indicators [PDF]
, 2001 We calculate the distributions of the total burst energy, the peak luminosity and the X-ray afterglow energy using burst observations and distances to the associated host galaxies.

Uncertainties on Clusters of Galaxies Distances
, 2000 6 pages, 1 table, 3 figures, accepted in A&AWe investigate in this paper the error on the cluster redshift estimate as a function of: (1) the number of galaxy structures along the line of sight; (2) the morphology of the clusters (regular/substructures);

Application of photometric redshifts on the correlation properties of galaxies and matter [PDF]
, 2007 In the past years cosmology, the science of the universe as a whole, has seen tremendous progress. The Lambda-Cold-Dark-Matter scenario is widely accepted as the standard model of cosmology describing the evolution of the universe and its main ...

Gamma-ray burst host galaxies have normal luminosities
, 2000 The galactic environment of gamma-ray bursts can provide good evidence about the nature of the progenitor system, with two old arguments implying that the burst host galaxies are significantly subluminous. New data and new analysis have now reversed this

, 2006 Aims. We study galaxy clustering and explore the dependence of galaxy properties on the the environment up to a redshift z ? 1, on the basis of a deep multi-band survey in the Chandra Deep Field South. Methods.

The Redshift Distribution and Luminosity Functions of Galaxies in the Hubble Deep Field
, 2007 Photometric redshifts have been determined for the galaxies in the Hubble Deep Field. The resulting redshift distribution shows two peaks: one at z ¸ :5 and one at z ¸ 2:5. Luminosity functions derived from the redshifts show strong luminosity evolution
