I was wondering how to calculate either the present comoving distance or the light travel distance when the source material only gives one value?
Is there and an online calculator or simple equation using Hubble constant that someone like myself who is not mathematically advanced can use to calculate these values?
The reason for this question is that I wanted to know the light travel time for the LQG's and other large distant cosmic structures so that I know the age at which we are looking at them but the sources only give their present comoving distance. Other sources also only give the light traveled time for distant objects and not present co-moving distance.
Edit- For the time being I only need to know the light travel distance for objects at a 9 billion light year comoving distance as this is the rough distance for the Giant GRB Ring, Huge-LQG, The Giant Arc, U1. 11 LQG and Clowes-Campusano LQG. Or if anyone knows a source that states the light travel distance for any mentioned.
I could post that as a separate question if the community thinks it should be?
