PUG Seminar

Whitmore 321 (IGC Lounge)

PUG Seminar

Although classically black holes could be characterized as perfect absorbers, this is no longer true once quantum effects are taken into account. In fact, black holes are not black: they “glow red” with radiation. In this talk, we will introduce the Hawking effect and illustrate how it can be used to cook up some eggs. Physical implications will be qualitatively reviewed. The focus will be on building an intuitive picture of the physics by utilizing order-of-magnitude estimates and toy models.

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.
