We present the evolution of the luminosity–size and stellar mass–size relations of luminous (L V 3.4×10 10 h 70 −2 L ⊙) and of massive (M ⋆ 3×10 10 h 70 −2 M ⊙) galaxies in the last ∼11 Gyr. We use very deep near–infrared images of the Hubble Deep Field–South and the MS1054-03 field in the J s , H and K s bands from FIRES to retrieve the sizes in the(More)
We present the evolution of the rest-frame optical luminosity density, j rest λ , of the integrated rest-frame optical color, and of the stellar mass density, ρ * , for a sample of K s-band selected galaxies in the HDF-S. We derived j rest λ in the rest-frame U , B, and V-bands for galaxies with lV> 1.4 × 10 10 h −2 70 L ⊙. For a complete sample of K s(More)
We present deep near-infrared (NIR) J s , H, and K s-band ISAAC imaging of the WFPC2 field of the Hubble Deep Field South (HDF-S). The 2.5 ′ × 2.5 ′ high Galactic latitude field was observed with the VLT under the best seeing conditions with integration times amounting to 33.6 hours in J s , 32.3 hours in H, and 35.6 hours in K s. We reach total AB(More)
We report deep Keck narrow-band Lyα images of the luminous z > 3 radio galaxies 4C 41.17, 4C 60.07, and B2 0902+34. The images show giant, 100−200 kpc scale emission line nebulae, centered on these galaxies, which exhibit a wealth of morphological structure, including extended low surface brightness emission in the outer regions, radially directed(More)
Perhaps as many as 10% of high redshift radio galaxy (HzRG; z > 2) candidates that are selected using an Ultra Steep radio Spectrum (USS) criterion fail to show optical emission (continuum, lines) in deep Keck exposures. Their parent objects are only detected in the near-IR and are probably heavily obscured and/or at very high redshift. To search for(More)

We use very deep near-infrared photometry of the Hubble Deep Field South taken with ISAAC/VLT to identify a population of high redshift galaxies with rest-frame optical colors similar to those of nearby galaxies. The galaxies are chosen by their infrared colors J s − K s > 2.3, aimed at selecting galaxies with redshifts above 2. When applied to our dataset,(More)
LOFAR, the Low Frequency Array, is a large radio telescope consisting of approximately 100 soccer-field sized antenna stations spread over a region of 400 km in diameter. It will operate at frequencies from ∼ 10 to 240 MHz, with a resolution at 240 MHz of better than an arcsecond. Its superb sensitivity will allow for studies of a broad range of(More)
The ultimate goal of terrestrial planet-finding missions is not only to discover terrestrial exoplanets inside the habitable zone (HZ) of their host stars but also to address the major question as to whether life may have evolved on a habitable Earth-like exoplanet outside our Solar System. We note that the chemical evolution that finally led to the origin(More)
