At luminosities above 1011 L , infrared galaxies become the dominant population of extragalactic objects in the local Universe (z ∼ 0.3), being more numerous than optically selected starburst and Seyfert galaxies and quasi-stellar objects at comparable bolometric luminosity. The trigger for the intense infrared emission appears to be the strong(More)
We present photometric observations of an apparent Type Ia supernova (SN Ia) at a redshift of D1.7, the farthest SN observed to date. The supernova, SN 1997†, was discovered in a repeat observation by the Hubble Space Telescope (HST ) of the Hubble Deep Field-North (HDF-N) and serendipitously monitored with NICMOS on HST throughout the Thompson et al.(More)
The distribution of black hole (BH) masses M• in galaxies is constrained by photometric and kinematic studies of individual galaxies, and by the properties of the quasar population. I review our understanding of these topics, present new results of adiabatic BH growth models for HST photometry of elliptical galaxies with brightness profiles of the ‘core’(More)
The Cosmic Evolution Survey (COSMOS) is designed to probe the correlated evolution of galaxies, star formation, active galactic nuclei (AGNs), and dark matter (DM) with large-scale structure (LSS) over the redshift range z > 0:5Y6. The survey includes multiwavelength imaging and spectroscopy from X-rayYtoYradio wavelengths covering a 2 deg area,(More)
We present imaging data and photometry for the COSMOS survey in 15 photometric bands between 0.3 and 2.4 m. These include data taken on the Subaru 8.3 m telescope, the KPNO and CTIO 4 m telescopes, and the CFHT 3.6 m telescope. Special techniques are used to ensure that the relative photometric calibration is better than 1%across the field of view. The(More)
We present results from our Very Large Telescope large program to study the dynamical evolution of local Ultraluminous Infrared Galaxies (ULIRGs) and QSOs. Expanding previous studies by Genzel et al. (2001) and Tacconi et al. (2002), our data now consist of high resolution, long-slit Hand K-band spectra of 54 ULIRGs. This paper mainly presents the(More)
zCOSMOS is a large-redshift survey that is being undertaken in the COSMOS field using 600 hr of observation with the VIMOS spectrograph on the 8mVLT. The survey is designed to characterize the environments of COSMOS galaxies from the 100 kpc scales of galaxy groups up to the 100 Mpc scale of the cosmic web and to produce diagnostic information on galaxies(More)
We present the first identification of large-scale structures (LSSs) at z < 1:1 in the Cosmic Evolution Survey (COSMOS). The structures are identified from adaptive smoothing of galaxy counts in the pseudo-3D space ( , , z) using the COSMOS photometric redshift catalog. The technique is tested on a simulation including galaxies distributed in model clusters(More)
We present a full high resolution SPIRE FTS spectrum of the nearby ultraluminous infrared galaxy Mrk 231. In total 25 lines are detected, including CO J = 5−4 through J = 13−12, 7 rotational lines of H2O, 3 of OH and one line each of H2O, CH, and HF. We find that the excitation of the CO rotational levels up to J = 8 can be accounted for by UV radiation(More)
