Constraining the AGN Luminosity Function from JWST with the X-Ray Background
The Astrophysical Journal Letters, 2023 We predict the X-ray background (XRB) expected from the population of quasars detected by the James Webb Space Telescope spectroscopic surveys over the redshift range z ∼ 4–7.

Beyond the Galaxy Luminosity Function [PDF]
Publications 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 white dwarf luminosity function [PDF]
New Astronomy Reviews, 2016 White dwarfs are the final remnants of low- and intermediate-mass stars. Their evolution is essentially a cooling process that lasts for $\sim 10$ Gyr. Their observed properties provide information about the history of the Galaxy, its dark matter content and a host of other interesting astrophysical problems.

The Truncated Lindley Distribution with Applications in Astrophysics
Galaxies, 2019 This paper reviews the Lindley distribution and then introduces the scale and the double truncation. The unknown parameters of the truncated Lindley distribution are evaluated with the maximum likelihood estimators.

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 ...

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.

New Galaxy UV Luminosity Constraints on Warm Dark Matter from JWST
The Astrophysical JournalWe 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-

Modeling the Near-Infrared Luminosity Functions of Young Stellar Clusters [PDF]
, 1999 We present the results of numerical experiments designed to evaluate the usefulness of near-infrared luminosity functions for constraining the Initial Mass Function (IMF) of young stellar populations.
