About me

My interestes lie in supernovae as distance indicators (cosmology), the physics of supernovae (such as explosion mechanism and progenitors), and other stellar transients in general (e.g., kilonovae, tidal disruption events, etc.). I am also interested in machine learning and coding in Python.

I am the developer of the PISCOLA transient light-curve fitter and HostPhot for galaxy photometry, and I am an active member in collaborations such as ePESSTO+, POSIE, ZTF and SAINTS.

Currently, I am a research fellow at Trinity College Dublin (TCD) and previously was a postdoctoral researcher at the Institute of Space Sciences (ICE-CSIC) in Barcelona, Spain. At the moment, my work focuses on using type Ia supernovae with near-infrared data to test the current standard cosmological model as part of the Aarhus-Barcelona Flows project and SAINTS collaboration.

Fitting Data - Basic implementation of Python packages

In this notebook I show some basic implementation of different Python packages for data fitting. The idea is to learn the different options there are out there so the reader can then study them in more detail if needed.
