Is there a way to convert distance modulus to get H(z) values

[fab13]

TL;DR

I have a set of distance modulus and I would like to know if this is possible to convert these values into a Hubble vs redshift H(z) data ( with the standard deviation)

Hello,

Everything is in th summary :

I have a set of distance modulus and I would like to know if this is possible to convert numerically these values into a Hubble vs redshift H(z) data ( with the standard deviation).

Any relation between distance modulus and H(z) are welcome.

Regards

It's easy to convert distance modulus to distance. See this Wikipedia page for example. But do you also have redshift for these objects? How can you plot a Hubble curve without redshift data?

@phyzguy

Of course, I forgot to mention that data are not in H(z) space but distance_modulus(z)

that's why I would like to handle them to get H(z) data

Thanks

Redshifts are not in a fixed number of Hz. They are fractions of the original frequency,
