Galaxies radiate energy from their stars, but there is also flows of matter into a galaxy.
Is the net energy produced by these flows of matter (evaluated as E=mc^2 under the assumption that it will be processed by stars as nuclear fuel) occurring at a greater or lesser rate than the radiative losses from the stellar population of our galaxy?
If anyone is aware of a good study on this topic that would be appreciated.
