Specific Intensity, Flux, Flux Density, Radiative Transfer

AI Thread Summary
Specific intensity refers to the amount of energy radiated by a source per unit area per unit frequency, while flux is the total energy passing through a surface per unit time. Flux density is the amount of energy per unit area per unit time, and monochromatic specific intensity focuses on a specific frequency of radiation. Understanding these terms is crucial for analyzing radiative transfer in astronomical contexts. Resources like astronomy glossaries can provide further clarification and equations for practical application.

Hi, I'm new to the technical aspects of astronomy and I'm having trouble quantifying what the definitions of some of these terms are. I can find equations that relate most of them, but I'm not sure how to use any of them.

The terms are specific intensity, flux, flux density, and monochromatic specific intensity. I've tried searching for websites that relate to these terms but so far I'm out of luck.

Any help is greatly appreciated.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
