ICDS Physics SCIMMA AMON LIGO Gravitational Waves Multimessenger Astrophysics IGC

I am an assistant researcher for the Institute of Gravitation and the Cosmos. I work with Dr. Bangalore Sathyaprakash to measure cosmological parameter anisotropy with gravitational wave events expected for future detector networks. I also work with Dr. Chad Hanna to support gravitational-wave and multi-messenger astrophysics via research cyberinfrastructure, including the Scalable Cyberinfrastructure for Multi-Messenger Astrophysics (SCiMMA) project, the Astrophysical Multimessenger Observatory Network (AMON), and the SuperNova Early Warning System (SNEWS). I also collaborate with PSU's Institute for Computational and Data Sciences (ICDS) to develop cyberinfrastructure for the GWave computing cluster.

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.
