Looks great thank you. Are you also able to write a couple of short tests for this function? You would need to create:

• skypy/supernova/tests (directory)
• skypy/supernova/tests/__init__.py (empty file)
• skypy/supernova/tests/test_rate.py

And in test_rate.py you would write a function Ia_redshift_rate that runs a few simple tests. Perhaps look at test_size.py for inspiration. E.g. you could write a test that checks the units of the output are correct

[rrjbca]

I think this whitespace will fix your PEP8 error. Also I think it should be units.year ** -1 is that correct?

Suggested change

	rate = r0*(1+redshift)**a * units.year *(units.Mpc)**-3
	rate = r0 * (1+redshift) ** a * units.year ** -1 * (units.Mpc) ** -3

[rrjbca]

Wondering what are these default values? Are they "standard" values? I would generally prefer them to not have defaults in most cases. They should also be documented under 'Parameters' even if it just says 'free parameters of the model'

[rrjbca]

Will probably have to update the units here as well

Closed in favour of #540 which targets the correct branch of module/supernovae
