I am in experimental particle astrophysics working under Dr. Stephane Coutu to study high energy cosmic rays.
B.S. (Physics), Utah State University, 2023
Heather Allen's research group news
First flight of HELIX
2024-07-10
The High Energy Light Isotope eXperiment is designed to measure various isotopes of cosmic ray nuclei, which are sensitive to the history of propagation of these energetic particles through our Milky Way galaxy, and which are linked to energetic interactions in the interstellar medium (yielding antimatter as well as rare nuclei). The instrument had its first stratospheric balloon flight on May 28, 2024 from the Esrange rocket/balloon base in northern Sweden, landing on Ellesmere Island in the Canadian high Arctic after more than 6 days. The Penn State group includes IGC faculty Stephane Coutu and Isaac Mognet, and past and present students Heather Allen, Carl Chen, Alex Pazoki and Monong Yu.
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.
