A Derivation of the Luminosity Function of the Kuiper Belt from a Broken Power-Law Size Distribution

, 2008
We have derived a model of the Kuiper belt luminosity function exhibited by a broken power-law size distribution. This model allows direct comparison of the observed luminosity function to the underlying size distribution.

The X-ray luminosity function of local galaxies [PDF]

, 1999
We present an estimate of the local X-ray luminosity function and emissivity for different subsamples of galaxies namely Seyferts, LINERS, star-forming and passive (no-emission-line) galaxies.

New Galaxy UV Luminosity Constraints on Warm Dark Matter from JWST

The Astrophysical Journal
We exploit the recent James Webb Space Telescope (JWST) determination of galaxy UV luminosity functions over the redshift range z = 9–14.5 to derive constraints on warm dark matter (WDM) models. The delayed structure formations in WDM universes make high-

The Origin of the Consistent Planetary Nebula Luminosity Function Bright-end Cutoff

The Astrophysical Journal, 2023
The [O iii ] 5007 Å line is typically the brightest line in planetary nebula (PN) spectra. Observations show that the brightest [O iii ] 5007 Å PN in a galaxy—the planetary nebula luminosity function (PNLF) bright-end cutoff—is surprisingly independent ...

Luminosity functions of cluster galaxies [PDF]

Astronomy & Astrophysics, 2018
We derive NUV luminosity functions for 6471 NUV detected galaxies in 28 0.02 < z < 0.08 clusters and consider their dependence on cluster properties. We consider optically red and blue galaxies and explore how their NUV LFs vary in several cluster subsamples, selected to best show the influence of environment.

The gamma-ray luminosity function of millisecond pulsars and implications for the GeV excess [PDF]

, 2015
It has been proposed that a large population of unresolved millisecond pulsars (MSPs) could potentially account for the excess of GeV-scale gamma-rays observed from the region surrounding the Galactic Center.

Adenosine‐to‐inosine editing of miR‐200b‐3p is associated with the progression of high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.

How covariant is the galaxy luminosity function?

, 2012
We investigate the error properties of certain galaxy luminosity function (GLF) estimators. Using a cluster expansion of the density field, we show how, for both volume and flux limited samples, the GLF estimates are covariant.

Near-infrared luminosity function and colours of dwarf galaxies in the Coma Cluster [PDF]

, 1997
We present K-band observations of the low-luminosity galaxies in the Coma cluster, which are responsible for the steep upturn in the optical luminosity function at M_R ~ -16, discovered recently.

Luminosity Function of Galaxies in Voids: A Modification Inspired by Excursion Set Theory

The Astrophysical Journal
In the standard picture of cosmology, the galaxies reside in dark matter (DM) halos. DM halos are distributed in the cosmic web in different environments.
