Ágnes Kis-Tóth

teaching fellow

PhD candidate (Eötvös Loránd University, Budapest)

 

Biography:

Firstly I was enchanted by mathematics, so I started my journey as a mathematician on the field of differential geometry and functional analysis. I wrote my thesis about linear operators on topological vectorspaces. During my math studies at the ELTE university I discovered another true passion: teaching. While I was already teaching math in a university I finally succumbed to the temptation of physics and went back to studying again. During my bachelor years I joined a research group in the Department of Materials Physics at ELTE. With my supervisor Ádám Révész I was working on hydrogen storage in magnesium based amorphous alloys.

I also did my master's studies at ELTE but my interest shifted to astrophysics and particle physics. With the guidance of Zsolt Frei and Zoltán Haiman I engaged an astrophysical research in the Department of Atomic Physics. Now I am a PhD student and the subject of my research is "cosmological ionized bubbles and the era of reionization". I recreated the model of the classical strömgren spheres around hot stars and modified it to the so called cosmological case, where the ionizing source is a quasar, and the environment is the low density intergalactic medium in the expanding universe before cosmological reionization. I am still developing this model to give the best possible estimation on the spectrum of these ionized bubbles, which we may observe in the near future.
