Research Interests

Professor Kara is an observational astrophysicist, working to understand the physics behind how black holes grow and affect their environments. She has advanced a new technique called X-ray reverberation mapping, which allows astronomers to map the gas falling on to black holes and measure the effects of strongly curved spacetime close to the event horizon. She also works on variety of transient phenomena, such as Tidal Disruption Events, Quasi Periodic Eruptions and Galactic black hole outbursts. She also works to develop new and future space missions; she is the Deputy Principal Investigator of the AXIS Probe Mission Concept, which, if selected, will launch in 2032. She is also a NASA-selected Participating Scientist on several approved international space missions, including the newly launched XRISM Mission (focusing on high-resolution X-ray spectroscopy), the ULTRASAT mission (a UV all-sky time domain surveyor set to launch in 2027) and the LISA Observatory (a first low-frequency gravitational wave observatory to launch in 2035).

How do supermassive black holes shape the evolution of galaxies? What does an event horizon really look like? Why do black holes emit bursts of energy called ‘relativistic jets’?

In search of answers to these questions, astrophysicist Erin Kara explores black holes by carefully tracking the gas and plasma swirling near their event horizons. To reconstruct the immediate environment, Kara turns to the X-ray light given off by the accretion disk, measuring the timing of photons using a telescope mounted on the International Space Station. This technique — called reverberation mapping — works in a manner similar to how bats ‘see’ using sound echolocation, allowing researchers to infer the structure of the gas and plasma with remarkable resolution. ———- Read the full article: https://www.quantamagazine.org/to-see… Video: Quanta Magazine/YouTube.

Biographical Sketch

Erin Kara is the Class of 1958 Career Development Assistant Professor of Physics. She is an observational astrophysicist, working to understand the physics behind how black holes grow and affect their environments. She also works to develop new and future space missions. She co-chairs the supermassive black hole working group of the XRISM Observatory, a joint JAXA / NASA X-ray spectroscopy mission to launch in 2023, and is the Deputy Principle Investigator of the AXIS Probe Mission Concept.

Erin is originally from Bethlehem, Pennsylvania, and attended Barnard College of Columbia University, where she obtained a B.A. in physics with a minor in art history. After graduating in 2011, she moved to the United Kingdom on a Gates Cambridge Scholarship to study for a Masters and a PhD from the Institute of Astronomy at the University of Cambridge. In 2015, she was awarded a NASA Hubble Postdoctoral Fellow, which she took to the University of Maryland and NASA’s Goddard Space Flight Center. In 2018, she became the Neil Gehrels Prize Postdoctoral Fellow at the University of Maryland, and joined the faculty of MIT as an Assistant Professor of Physics in July 2019. Recently, the American Astronomical Society awarded her the 2022 Newton Lacy Pierce Prize for ‘outstanding achievement, over the past five years, in observational astronomical research’.
