ANtartic Impulsive Transient Antenna

The primary objective of the ANtarctic Impulsive Transient Antenna (ANITA) mission is to extend the reach of NASA observatories into the realm of high energy neutrino astronomy to test the fundamental laws of high energy physics and astrophysics. Neutrinos and gravity waves are the only direct astrophysical messengers which reach earth unattenuated through space at all energies. ANITA will probe both the nature of the sources of these extreme particles, and the fundamental interactions of high energy physics at extreme scales. ANITA, as an Antarctic long-duration balloon flight, observes the Antarctic ice sheet out to a horizon approaching 700 km, giving a neutrino detection volume of near one million cubic kilometers.

About our wordmark
Monica 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.
