Quasar Host Galaxies in the FORS Deep Field
Context. The evolution of quasar host galaxies is still hardly studied at high redshifts (z > 2), although this is a very interesting redshift range as both the quasar activity and the star formation rate density have their peak at z ≈ 2–3. This makes is especially interesting to study properties of quasar host galaxies, such as the star formation rate or the black hole mass at this redshift. A...
متن کاملLyman Break Galaxies in the VLT / FORS 2 spectroscopic campaign in the GOODS - S field
We present initial results from our ongoing campaign of spectro-scopic identifications of Lyman–break galaxies (LBGs) at z ∼ 4, 5 and 6 with FORS2 at the ESO VLT.
متن کاملLy α emission galaxies at a redshift of z ≈ 5 . 7 in the FORS Deep Field ⋆
We present the results of a search for Lyα emission galaxies at z ≈ 5.7 in the FORS Deep Field. The objective of this study is to improve the faint end of the luminosity function of high-redshift Lyα emitting galaxies and to derive properties of intrinsically faint Lyα emission galaxies in the young universe. Using FORS2 at the ESO VLT and a set of special interference filters, we identified ca...
متن کاملAn integral - field spectroscopic strong lens survey
We present the observational results of a survey for strong gravitational lens systems consisting of extended emission-line galaxies lensed by intervening earlytype galaxies, conducted using integral field units (IFUs) of the Magellan IMACS and Gemini GMOS-N spectrographs. These data are highly valuable for corroborating the lensing interpretation of Hubble Space Telescope imaging data. We show...
متن کاملThe Chandra Deep Field - North Survey . Xvi
We present X-ray spectral analyses of the three z > 4 Active Galactic Nuclei (AGNs) thus far spectroscopically identified in the Chandra Deep Field-North Survey, at redshifts of 5.186, 4.424, and 4.137. These analyses are made possible by the extremely deep exposure (≈ 2 Ms) and the low Chandra background. The rest-frame ≈ 2.5–40 keV spectra are the first for optically faint (two of the three s...
