About Me

Introduction

I am Javier, a humble physics master of science student in Universidad de Chile. Until 2023 I was member of the Holographycl Anillo group and currently I'm part of Cosmology and Theoretical Astrophysics FCFM group.

In this webpage you can find: personal notes, FI2001, FI2002 and FI3111 (FCFM) T.A. course material and research stuff.

Research Experience

Renormalization in cosmology Present

Advisor: Gonzalo Palma

Considering quantum loops corrections to Feynman diagrams usually implies the presence of divergences that need to be renormalized using counterterms. We are renormalizating our theory with an arbitrary potential and diagrams with one vertex and an arbitrary number of loops.

Statistics of spectator fields with wavefunction of the Universe Present

Advisor: Gonzalo Palma

Considering multifield inflation models we can consider a spectator field that affects the evolution of the curvature perturbation. In this work we use the wavefunction of the Universe formalism in order to compute the PDF of this spectator field and, then, also the PDF of the primordial perturbation.

Super massive binary black hole merge Summer Internship 2022

Advisor: Andrés Escala

With 3D computer simulations we found a significant difference between SMBHBs with and without AGN feedback, contradicting a L. del Valle, M. Volonteri 2018 assertion.

Structures in protoplanetary disks 2021

Advisor: Aníbal Sierra

We studied the dust dynamics in young protoplanetary disks, analytically and using computer models simulating the observations that would be obtained with ALMA.

Conferences and Schools

Summer School on Cosmology ICTP Trieste, Italy

"This school provides an introduction to the current state of research in cosmology and astroparticle physics. It is intended for beginning graduate students, as well as more senior non-expert researchers interested in the field."

Perimeter-SAIFR Journeys into Theoretical Physics Sao Paulo, Brasil

"School aimed at outstanding undergraduates in their last year from all countries in Latin America. It is associated with a partnership between ICTP-SAIFR at IFT-UNESP and the Perimeter Institute for Theoretical Physics."
