CO luminosity functions for far-infrared- and B-band-selected galaxies and the first estimate for Omega(H I+H2)
surveys molecules
2014/12/24
We derive a nonparametric CO luminosity function using an FIR- and an optical B-band-selected sample of the galaxies included in the FCRAO Extragalactic CO Survey. The FIR-selected sample is defined u...
A complete view of galaxy evolution: panchromatic luminosity functions and the generation of metals
typical galaxies galaxies
2014/12/22
When and how did galaxies form and their metals accumulate? Over the last decade, this has moved from an archeological question to a live investigation: there is now a broad picture of the evolution o...
The VLA Survey of the Chandra Deep Field South. V. Evolution and Luminosity Functions of sub-mJy radio sources and the issue of radio emission in radio-quiet AGN
Chandra Deep Field Luminosity Functions radio sources radio emission
2011/10/9
We present the evolutionary properties and luminosity functions of the radio sources belonging to the Chandra Deep Field South VLA survey, which reaches a flux density limit at 1.4 GHz of 43 microJy a...
Early Black Holes in Cosmological Simulations: Luminosity Functions and Clustering Behaviour
quasars: general — galaxies: active — black hole physics — methods: numerical — galaxies: haloes
2011/9/29
We examine predictions for the quasar luminosity functions (QLF) and quasar clustering at high redshift (z > 4.75) using MassiveBlack, our new hydrodynamic cosmological simulation which includes a sel...
A Halo Model of Local IRAS Galaxies Selected at 60 Micron Using Conditional Luminosity Functions
Local IRAS Galaxies Selected 60 Micron
2011/1/11
Using conditional luminosity functions (CLFs) which encode the luminosity distribution of galaxies as a function of halo mass, we construct a halo model of IRAS galaxies selected at 60 micron. An abun...
ACCESS II: A Complete Census of Star Formation in the Shapley Supercluster - UV and IR Luminosity Functions
Star Formation the Shapley Supercluster - UV IR Luminosity Functions
2011/1/10
We present panoramic Spitzer/MIPS mid- and far-infrared and GALEX ultraviolet imaging of the the most massive and dynamically active system in the local Universe, the Shapley supercluster at z=0.048, ...
Environmental dependence of 8um luminosity functions of galaxies at z~0.8: Comparison between RXJ1716.4+6708 and the AKARI NEP deep field

2010/3/8
We aim to reveal environmental dependence of infrared luminosity functions (IR LFs) of galaxies at z~0.8 using the AKARI satellite. We construct restframe 8um IR LFs in the cluster region RXJ1716.4+6...
Evolution of Infrared Luminosity functions of Galaxies in the AKARI NEP-Deep field: Revealing the cosmic star formation history hidden by dust

2010/3/8
Dust-obscured star-formation becomes much more important with increasing intensity, and increasing redshift. We aim to reveal cosmic star-formation history obscured by dust using deep infrared observa...
