I am a Eberly Postdoctoral Scholar in Physics at Penn State. My research involves xenon purity physics and nuclear recoil (NR) calibrations of the LUX-ZEPLIN (LZ) Dark Matter Experiment. Sufficient understanding of xenon purity is needed for event reconstruction in the xenon time projection chamber (TPC) and NR calibrations allow understanding of detector response for an anticipated Weakly Interacting Massive Particle (WIMP) signal, which is expected to occur via nuclear recoils. LZ is located nearly a mile underground in South Dakota and features 10 tonnes of xenon for operation. LZ achieved a world-leading sensitivity to WIMP-like dark matter and continues to take data to further improve sensitivity.
The IGC wordmark was created by Monica Rincon Ramirez, while she was a graduate
student at the Institute for Gravitation and the Cosmos (IGC). Monica enjoys
drawing new connections between fundamental theory and observations. Her
graduate work includes specialized topics in general relativity, loop quantum
gravity, and quantum fields in cosmological backgrounds. In particular, her
thesis work focused on finding effective quantum corrections to gravitational
phenomena from spinfoams, and applications to cosmology. She received her PhD
in 2024.
The wordmark symbolizes the scope and variety of research at the IGC. The base
of the image represents quantum gravity, evoking the quantum geometrical
picture from spinfoams and loop quantum gravity. These are among the approaches
to fundamental questions studied at the Center for Fundamental Theory. The
middle of the image represents the Center for Theoretical and Observational
Cosmology by galaxies embedded in a smooth surface, characteristic of spacetime
in general relativity and the much larger physical scales studied in cosmology.
Finally, at the top, the surface curves to an extreme, representing a
supermassive black hole accompanied by an energetic jet. These elements depict
an active galactic nucleus, inspired by Centaurus A. Just to the right, a pair
of black holes approaches merger. This top portion of the wordmark represents
the Center for Multimessenger Astrophysics, which specializes in the study of
high-energy phenomena in the universe.
