On the normalized FRB luminosity function [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
Thirty-three fast radio bursts (FRBs) had been detected by March 2018. Although the sample size is still limited, meaningful statistical studies can already be carried out. The normalised luminosity function places important constraints on the intrinsic power output, sheds light on the origin(s) of FRBs, and can guide future observations. In this paper,

A Left and Right Truncated Schechter Luminosity Function for Quasars

open access: yesGalaxies, 2017
The luminosity function for quasars (QSOs) is usually fitted by a Schechter function. The dependence of the number of quasars on the redshift, both in the low and high luminosity regions, requires the inclusion of a lower and upper boundary in the ...

Luminosity-time and luminosity-luminosity correlations for GRB prompt and afterglow plateau emissions

open access: yes, 2015
We present an analysis of 123 gamma-ray bursts (GRBs) with known redshifts possessing an afterglow plateau phase. We reveal that La-T∗a correlation between the X-ray luminosity La at the end of the plateau phase and the plateau duration, T∗a, in the GRB ...

The Luminosity Function of Galaxies in Some Nearby Clusters

open access: yesUHD Journal of Science and Technology, 2021
In the present work, the galaxy luminosity function (LF) has been studied for a sample of seven clusters in the redshift range (0.0 ≲ z ≲ 0.1), within Abell radius (1.5 h−1 Mpc), in the five SDSS passbands ugriz.

THE PROTOSTELLAR LUMINOSITY FUNCTION [PDF]

open access: yesThe Astrophysical Journal, 2011
The protostellar luminosity function (PLF) is the present-day luminosity function of the protostars in a region of star formation. It is determined using the protostellar mass function (PMF) in combination with a stellar evolutionary model that provides the luminosity as a function of instantaneous and final stellar mass. As in McKee & Offner (2010)

On the mass distribution of stars in the solar neighborhood [PDF]

open access: yesSerbian Astronomical Journal, 2006
The present authors analyze samples consisting of Hipparcos stars. Based on the corresponding HR diagrams they estimate masses of Main-Sequence stars from their visual magnitudes. They find that already beyond the heliocentric radius of 10 pc the effects
