useful details?

i've put some stuff in here, but i really have no time to sort it out at the mo. i figure its better here than not though. even if its just here for me to fix a later date. g/l ok, the page is a good start, but we need to have some calculable equations here i think or references to them. we can start with

"The magnitude-redshift relation of SNe Ia measures the luminosity distance, dL, as a

function of redshift, z, via the relation

m −M = log10 dL(z),

where m is the relative magnitude of the supernova and M is its absolute magnitude.

...

dL(z) = z(1 + z/2)/H0 " this for an empty universe (no HII in the way or aught) .?

If anyone gets around to it, it would indeed be useful to include a (model independent) definition of the cosmological luminosity distance. I can't right now since my homework is to find it.... --128.42.162.102 03:17, 27 March 2006 (UTC)[reply]

In this definition is not included the relativistic correction of red-shift!!!!!! --Lulo88 (talk) 10:20, 23 January 2010 (UTC)[reply]
