Research Summary

I search the skies to find stars that happen to pass a bit too close to a supermassive black hole. Due to the strong gravity of the black hole, these unlucky stars get torn apart into streams of gas. The result is a sudden increase of fuel for the black hole, leading to a panchromatic flare of light. With my team of collaborators, we have recently collected a large sample of these rare and valuable events. I will use this sample to learn about the origin of black holes in the early Universe.
