I am a Ph.D. student in Astronomy at the University of Padova, working in INAF – Osservatorio Astronomico di Padova.

My research project is on Interacting Supernovae , in particular Type IIn SNe. The observables of these SNe are determined by strong interaction between the supernova ejecta and a dense, hydrogen-rich circumstellar medium (CSM). The ejecta-CSM interaction converts a significant fraction of the kinetic energy into radiation, producing luminous and long-lasting transients. Their spectra show Balmer lines with composite profiles. The narrow hydrogen lines are always seen in emission, ontop of broader spectral features.

My Ph.D. project is structured into two main work packages, which combine the analysis of archival data and new observations:

1. Statistical study of archival type IIn supernovae - I am conducting a statistical analysis of archival data from previously observed Type IIn SNe. By comparing their light curves and spectral evolution, I aim to identify common features and trends that can shed light on the physical processes governing their explosion mechanisms and the nature of their progenitors.

2. Real-Time Follow-up of Newly Discovered Interacting Supernovae - I will focus on the follow-up and detailed study of two newly discovered interacting SNe that will explode in the next couple of years. I will observe these events in real-time, coordinating observations and data collection. In this work I will analyze their light curves and spectra with a multi-wavelength coverage (from the ultraviolet to the mid-infrared domains). This will allow me to investigate in detail the emission produced by the ejecta-CSM interaction and reconstruct the mass-loss history of the progenitor.
