Thinking as a physics generalist but not an astronomer, I'd describe these things as:

1. Super nova happens near a black hole. Stuff (including photons) that emanate with a speed and direction sufficient to overcome the escape velocity of the system will have happy sailing. Photons at the speed of light, massive stuff slowed down. The rest will be sucked into the hole. The result would be a directional burst that favors photons over massive material.

2. Same as saying that a neutron star falls into black hole.
