Last updated

Jenny Greene (born October 9, 1978) is an Astrophysicist and Professor of Astrophysical Sciences at Princeton University. She is notable for her work on supermassive black holes and the galaxies in which they reside. Her work also involves a partnership with the Princeton Gravity Initiative and as co-founder and academic advisor to the Prison Teaching Initiative (PTI) at Princeton University. [1] [2]

Early life and education

In 2000, Greene received a B.S in astronomy and physics (summa cum laude) from Yale University. She then attended Harvard for her Ph.D in Astronomy, her thesis entitled The Growth of Black Holes: From Primordial Seeds to Local Demographics. [3]

Career

Academic Career

After her post-doctoral fellowship at Princeton, she became an Assistant Professor of Astronomy at UT Austin for a year. Since 2011, she has been a faculty member of the Astrophysical Sciences department at Princeton and is currently a professor of astrophysics. [4]

Research

Her broad research interests include measurements of black hole masses, the connection between supermassive black holes and galaxies, stellar and gas kinematics of galactic nuclei, and diffuse light in galaxy clusters. A recent study from 2022, "The Nature of Low-surface-brightness Galaxies in the Hyper Suprime-Cam Survey" [5] highlights Greene's research contributions in utilizing innovations in imaging technology for an intensive study in the ability to distinguish and identify low-surface-brightness galaxies.

Prison Teaching Initiative (PTI) at Princeton University

The PTI provides college-level education and other educational opportunities, such as research experiences for undergraduate students, to the incarcerated and formerly incarcerated in New Jersey correctional facilities. [1] Greene has been involved in the effort and growth of the PTI as a post-doc fellow at Princeton since its founding in 2005 and as academic advisor of the program in 2017, when REUs through PTI began.

<span class="mw-page-title-main">Seyfert galaxy</span> Class of active galaxies with very bright nuclei

Seyfert galaxies are one of the two largest groups of active galaxies, along with quasars. They have quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, their host galaxies are clearly detectable.

<span class="mw-page-title-main">Supermassive black hole</span> Largest type of black hole

A supermassive black hole is the largest type of black hole, with its mass being on the order of hundreds of thousands, or millions to billions of times the mass of the Sun (M). Black holes are a class of astronomical objects that have undergone gravitational collapse, leaving behind spheroidal regions of space from which nothing can escape, not even light. Observational evidence indicates that almost every large galaxy has a supermassive black hole at its center. For example, the Milky Way galaxy has a supermassive black hole at its center, corresponding to the radio source Sagittarius A*. Accretion of interstellar gas onto supermassive black holes is the process responsible for powering active galactic nuclei (AGNs) and quasars.

<span class="mw-page-title-main">Intermediate-mass black hole</span> Class of black holes with a mass range of 100 to 100000 solar masses

An intermediate-mass black hole (IMBH) is a class of black hole with mass in the range 102–105 solar masses: significantly more than stellar black holes but less than the 105–109 solar mass supermassive black holes. Several IMBH candidate objects have been discovered in our galaxy and others nearby, based on indirect gas cloud velocity and accretion disk spectra observations of various evidentiary strength.

The Event Horizon Telescope (EHT) is a large telescope array consisting of a global network of radio telescopes. The EHT project combines data from several very-long-baseline interferometry (VLBI) stations around Earth, which form a combined array with an angular resolution sufficient to observe objects the size of a supermassive black hole's event horizon. The project's observational targets include the two black holes with the largest angular diameter as observed from Earth: the black hole at the center of the supergiant elliptical galaxy Messier 87, and Sagittarius A* at the center of the Milky Way.
