Characterizing the luminosity components of luminous infrared galaxies in multi-wavelength from the X-ray to the far-infrared [PDF]

open access: yesScientific Reports
We characterize luminosity components of Ultra/Luminous Infrared Galaxies (U/LIRGs) in multi-wavelength from the X-ray to far-infrared. A set of 63 AGN U/LIRGs was selected where these galaxies are powered by a central active galactic nucleus (AGN ...

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.
