I am a gravitational-wave astrophysicist

I am a gravitational-wave astrophysicist, looking to understand how supermassive black holes in the centers of massive galaxies merge. I do this by predicting their nanohertz gravitational-wave signatures, which will soon be detected by pulsar timing array experiments. With pulsar timing data, I look for both individual supermassive black holes in binary systems, and for the gravitational-wave background which should be generated by their cosmic merger history.

I am an assistant professor at the University of Connecticut, and an associate research scientist at the Center for Computational Astrophysics (CCA) at the Flatiron Institute. Before joining the CCA I was a Marie Curie International Outgoing Fellow at Caltech and at the Max Planck Institute for Radio Astronomy. I completed my PhD in 2014 at the University of Birmingham (UK) with Alberto Vecchio.

News updates

January 14th 2021: Here is my interview with BBC World Service about the first "hint" of the gravitational-wave background in the NANOGrav 12.5-yr data!

At the AAS we presented the new gravitational-wave background results from the NANOGrav 12.5-yr data! Punchline: there is something there, but we're not yet convinced it's the background. We need more data! Press release here, 

I've co-authored a few new papers! 

• My student Andrew Casey-Clyde led this great new paper! Casey-Clyde, Mingarelli, Greene et al. "A Quasar-based Supermassive Black Hole Binary Population Model: Implications for the Gravitational Wave Background", ApJ (2022),  arXiv:2107.11390 
• Undergraduate Chengcheng Xin did some great work with me and Jeff Hazboun on this paper! Xin, Mingarelli, Hazboun, "Multimessenger Pulsar Timing Array Constraints on Supermassive Black Hole Binaries Traced by Periodic Light Curves", (ApJ 2021)  arXiv:2009.11865
