How do these Euclid images connect to your research?

My own research is on the centers of galaxies, particularly their central black holes. Most supermassive black holes don’t do very much. Like the one in the center of our galaxy, they sit there, taking in matter when it gets too close, but they don’t take in much matter or have bright accretion flows because matter isn’t being forced inside.

One of the questions I’m most interested in is, what causes a black hole to become active, take in lots of material and have bright accretion flows? We can only study that with the kinds of multi-scale views of a galaxy that Euclid is providing. I also study jets: large and energetic flows of matter coming out of the centers of galaxies that are actively accreting. Euclid’s wide-angle view is going to give us an appreciation of their structure and impact on surrounding matter in new ways we’ve never been able to look at before.
