ON THE INTERPRETATION OF THE GLOBULAR CLUSTER LUMINOSITY FUNCTION [PDF]

open access: yesThe Astrophysical Journal, 2009
The conversion of the globular cluster luminosity function (GCLF, dN/dlogL) to the globular cluster mass function (GCMF, dN/dlogM) is addressed. Dissolving globular clusters (GCs) become preferentially depleted in low-mass stars, which have a high mass-to-light ratio.

Consistency between the luminosity function of resolved millisecond pulsars and the galactic center excess [PDF]

open access: yes, 2017
Fermi Large Area Telescope data reveal an excess of GeV gamma rays from the direction of the Galactic Center and bulge. Several explanations have been proposed for this excess including an unresolved population of millisecond pulsars (MSPs) and self ...

THE GALAXY UV LUMINOSITY FUNCTION BEFORE THE EPOCH OF REIONIZATION [PDF]

open access: yesProceedings of the International Astronomical Union, 2015
We present a model for the evolution of the galaxy ultraviolet (UV) luminosity function (LF) across cosmic time where star formation is linked to the assembly of dark matter halos under the assumption of a mass-dependent, but redshift-independent ...

Theoretical Systematics in Testing the Cosmological Principle with the Kinematic Quasar Dipole

open access: yesThe Astrophysical Journal, 2023
The Cosmological Principle (CP) is part of the foundation that underpins the standard model of the Universe. In the era of precision cosmology, when stress tests of the standard model are uncovering various tensions and possible anomalies, it is critical

The dust un-biased cosmic star formation history from the 20 cm VLA-COSMOS survey [PDF]

open access: yes, 2008
We derive the cosmic star formation history (CSFH) out to z=1.3 using a sample of ~350 radio-selected star-forming galaxies, a far larger sample than in previous, similar studies.

MUSE deep-fields: the Ly α luminosity function in the Hubble Deep Field-South at 2.91 < z < 6.64 [PDF]

open access: yes, 2016
We present the first estimate of the Ly{\alpha} luminosity function using blind spectroscopy from the Multi Unit Spectroscopic Explorer, MUSE, in the Hubble Deep Field South. Using automatic source-detection software, we assemble a homogeneously-detected

The luminosity function of field galaxies

open access: yes, 2011
Schmidt's method for construction of luminosity function of galaxies is generalized by taking into account the dependence of density of galaxies from the distance in the near Universe.

The 5–10 keV AGN luminosity function at 0.01 < z < 4.0 [PDF]

open access: yes, 2016
The active galactic nuclei X-ray luminosity function traces actively accreting supermassive black holes and is essential for the study of the properties of the active galactic nuclei (AGN) population, black hole evolution, and galaxy-black hole ...

The Effect of Superpositions on the Planetary Nebula Luminosity Function

open access: yesThe Astrophysical Journal, 2023
Planetary nebula (PN) surveys in systems beyond ∼10 Mpc often find high-excitation, point-like sources with [O iii ] λ 5007 fluxes greater than the apparent bright-end cutoff of the planetary nebula luminosity function (PNLF).
