The Galaxy Luminosity Function and Luminosity Density at Redshift z=0.1 [PDF]

open access: yesThe Astrophysical Journal, 2002
Using a catalog of 147,986 galaxy redshifts and fluxes from the Sloan Digital Sky Survey (SDSS), we measure the galaxy luminosity density at z = 0.1 in five optical bandpasses corresponding to the SDSS bandpasses shifted to match their rest-frame shape ...

Periphytic algae biomass at different shading levels: an experimental approach

open access: yesActa Limnologica Brasiliensia, 2021
: Aim Light is an essential component in the process of synthesis of organic compounds by photosynthetic organisms. Assuming that a higher level of luminosity would positively influence the production of biomass, we evaluated the influence of different ...

A Novel Luminance-Based Algorithm for Classification of Semi-Dark Images

open access: yesApplied Sciences, 2021
Image classification of a visual scene based on visibility is significant due to the rise in readily available automated solutions. Currently, there are only two known spectrums of image visibility i.e., dark, and bright.

Gamma-ray Burst Luminosity Relations: Two-dimensional versus Three-dimensional Correlations [PDF]

open access: yes, 2009
The large scatters of luminosity relations of gamma-ray bursts (GRBs) have been one of the most important reasons that prevent the extensive applications of GRBs in cosmology.
