They're from the quest "Rise in the East". Those explosions that happen are caused by those arrows. Actually, since sometimes arrows you're stuck with go into your inventory, you can pick them up during that quest by getting hit by those explosions. To use them you have to not have any other arrows in your inventory and equip your bow, and they'll autoequip. If you're on a console, anyway. On a PC, like OP said, just use the console.
