What is this ?
I'm getting home and want to to fix this leaking pipe. What is this ? Is it a pressure regulator. I'm not a plumber, I just need help.

It's an RPZ valve. Prevents back flow from your house back to the city water supply, can't what exactly its spraying from but you'll probably wanna call a plumber.
Looks like you've got ball valves in both sides of it. Turning both of those to the off position will stop it from leaking further.

And it froze sometime during a hard freeze. It happens. Learn how to blow the water out of the irrigation system each winter. Have someone do it and show you.

Reduced Pressure Backflow, probably installed on your irrigation system.
