The ISO 170um Luminosity Function of Galaxies [PDF]

open access: yes, 2005
We constructed a local luminosity function (LF) of galaxies using a flux-limited sample (S_170 > 0.195Jy) of 55 galaxies at z < 0.3 taken from the ISO FIRBACK survey at 170um.

The Faint End of the z = 5 Quasar Luminosity Function from the CFHTLS [PDF]

open access: yes, 2017
We present results from a spectroscopic survey of z ∼ 5 quasars in the CFHT Legacy Survey. Using both optical color selection and a likelihood method, we select 97 candidates over an area of 105 deg2 to a limit of iAB < 23.2, and 7 candidates in the ...

The Nearby Optical Galaxy Sample: The Local Galaxy Luminosity Function [PDF]

open access: yes, 1999
In this paper we derive the galaxy luminosity function from the Nearby Optical Galaxy (NOG) sample, which is a nearly complete, magnitude-limited ...

The quasar luminosity function at redshift 4 with the Hyper Suprime-Cam Wide Survey [PDF]

open access: yes, 2017
We present the luminosity function of z=4 quasars based on the Hyper Suprime-Cam Subaru Strategic Program Wide layer imaging data in the g, r, i, z, and y bands covering 339.8 deg^2.

The Dragonfly Nearby Galaxies Survey. III. The Luminosity Function of the M101 Group [PDF]

open access: yes, 2017
We obtained follow-up HST observations of the seven low surface brightness galaxies discovered with the Dragonfly Telephoto Array in the field of the massive spiral galaxy M101.

Luminosities of Carbon-rich Asymptotic Giant Branch stars in the Milky Way [PDF]

open access: yes, 2013
Stars evolving along the Asymptotic Giant Branch can become Carbon-rich in the final part of their evolution. They replenish the inter-stellar medium with nuclear processed material via strong radiative stellar winds.

The white dwarf luminosity function. I. Statistical errors and alternatives [PDF]

open access: yes, 2006
Over the years, several methods have been proposed to compute galaxy luminosity functions, from the most simple ones -counting sample objects inside a given volume- to very sophisticated ones -like the C- method, the STY method or the Choloniewski method,

Beyond the Galaxy Luminosity Function [PDF]

open access: yesPublications of the Astronomical Society of Australia, 2004
AbstractWith the advent of large-scale surveys (i.e. Legacy Surveys) it is now possible to start looking beyond the galaxy luminosity function (LF) to more detailed statistical representations of the galaxy population, i.e multivariate distributions.

The evolving far-IR galaxy luminosity function and dust-obscured star-formation rate density out to z~5 [PDF]

open access: yes, 2017
We present a new measurement of the evolving galaxy far-IR luminosity function (LF) extending out to redshifts z~5, with resulting implications for the level of dust-obscured star-formation density in the young Universe. To achieve this we have exploited

The Truncated Lognormal Distribution as a Luminosity Function for SWIFT-BAT Gamma-Ray Bursts

open access: yesGalaxies, 2016
The determination of the luminosity function (LF) in Gamma ray bursts (GRBs) depends on the adopted cosmology, each one characterized by its corresponding luminosity distance.
