Luminosity Function of the Local Universe 1
The measurement of the Star Formation Rate density of the Universe is of prime importance in understanding the formation and evolution of galaxies. The [OII]λ3727 emission line flux, easy to measure up to z≈1.4 within deep redshift surveys in the optical and up to z≈5.4 in the near infrared, offers a reliable means of characterizing the star formation properties of high-z objects. In order to p...
متن کاملPreprint typeset using L ATEX style emulateapj v. 03/07/07 THE [O II] λ3727 LUMINOSITY FUNCTION AT Z ∼ 1
We measure the evolution of the [O II] λ3727 luminosity function at 0.75 < z < 1.45 using highresolution spectroscopy of ∼ 14, 000 galaxies observed by the DEEP2 galaxy redshift survey. We find that brighter than L[OII] = 10 42 erg s the luminosity function is well-represented by a power law dN/dL ∝ L with slope α ∼ −3. The number density of [O II]-emitting galaxies above this luminosity declin...
متن کاملThe X-ray Luminosity Function of Bright Clusters in the Local Universe
We present the X-ray luminosity function (XLF) for clusters of galaxies derived from the RASS1 Bright Sample. The sample, selected from the ROSAT All-Sky Survey in a region of 2.5 sr within the southern Galactic cap, contains 130 clusters with flux limits in the range ∼ 3− 4× 10 ergs cm s in the 0.5-2.0 keV band. A maximum-likelihood fit with a Schechter function of the XLF over the entire rang...
متن کاملThe HerMES SPIRE submillimeter local luminosity function*
Local luminosity functions are fundamental benchmarks for high-redshift galaxy formation and evolution studies as well as for models describing these processes. Determining the local luminosity function in the submillimeter range can help to better constrain in particular the bolometric luminosity density in the local Universe, and Herschel offers the first opportunity to do so in an unbiased w...
