I've come across a few necromancy themed altars which have a beam of light going straight up into the sky (only at night, it seems) do they actually have a purpose?

Yes. These altars can be used to create Black Soul Gems, as found out during the Mages Guild quest-chain. To create a Black Soul Gem you must wait for the beam of light to appear at night (which happens only on specific nights), put a Grand Soul Gem in the altar, then cast Soul Trap on the altar.
