Daniel J. D'Orazio
Assistant Professor: Niels Bohr International Academy

I am an Assistant Professor, Sapere Aude Research Leader (Grant No. 121587), and Marie-Curie Fellow (Grant No. 101029157) at the Niels Bohr Institute. I lead a research group working on gravitational-wave astrophysics. 


Black Hole Binaries
We are looking for ways to find multi-messenger evidence for supermassive black hole binaries nearing merger. What will this tell us about the low-frequency gravitational wave sky, the growth of Supermassives and the astrophysical environments that facilitate these mergers? See, e.g., D'Orazio+2015, D'Orazio & Di Stefano 2018.

Circumbinary Accretion
The interaction of gas with binary systems is ubiquitous. Understanding the physics of this interaction allows us to understand how binary systems are sculpted and how we might find them from the light generated by accreting gas. See, e.g., D'Orazio & Duffell 2021 and resources from our 2022 KITP workshop.

Compact-Object Binaries
We are leveraging multi-band and multi-messenger techniques to understand the astrophysical origins of the growing population of stellar-mass compact-object binary mergers  detected via gravitational waves.  See, e.g., D'Orazio & Samsing 2018, D'Orazio + 2022.
