I am a graduate student in the Department of Physics at Penn State.

Binary neutron star mergers provide excellent laboratories for probing/testing nuclear physics at extreme densities- the kind which are not replicable on Earth. My research includes modeling these mergers via a combination of strong gravity and hydrodynamics and studying the allied high energy phenomenon.

In particular I am interested in studying several aspects of QCD phase transitions from hadrons to quarks in Neutron star cores as they evolve in a binary system and possible gravitational wave imprints which can be detected by 3rd generation gravitational wave detectors.

Other research interests include development of numerical methods for relativistic hydrodynamics.

About our wordmark
Monica Rincon Ramirez

The IGC wordmark was created by Monica Rincon Ramirez while she was a graduate student at the Institute. Monica enjoys drawing new connections between fundamental theory and observations. Her graduate work included general relativity, loop quantum gravity, and quantum fields in cosmological backgrounds; her thesis focused on effective quantum corrections to gravitational phenomena from spinfoams and applications to cosmology. She received her PhD in 2024.

The wordmark symbolizes the scope of research at the IGC. The base represents quantum gravity, evoking the quantum geometrical picture from spinfoams and loop quantum gravity — approaches studied at the Center for Fundamental Theory. The middle shows galaxies embedded in a smooth surface characteristic of spacetime in general relativity and the larger physical scales studied at the Center for Theoretical and Observational Cosmology. The top curves to an extreme representing a supermassive black hole accompanied by an energetic jet, with a binary black hole pair nearby — the high-energy phenomena studied at the Center for Multimessenger Astrophysics.
