I'm a cosmologist and I try to understand how our Universe is expanding using Type Ia Supernovae. I'm currently the lead of the cosmological analysis of the Dark Energy Survey (DES) Supernova sample, the largest and deepest SN sample from single telescope ever compiled.

Research Projects

Dark Energy Survey Supernova program

I'm leading the DES SN cosmology analysis. Results coming soon!! In the meantime, a quick spolier: contamination from non-Ia SNe and other sources of systematics don't dominate our measurement!

SN cosmology with LSST and TiDES

I am involved in the design of the Time-Domain Extragalactic Survey (TiDES), on the multi-object spectrograph 4MOST. Currently, TiDES is the only survey planned to perform systematic spectroscopic follow-up of LSST transients and transients' hosts. I've produced several cosmological forecasts from LSST and TiDES SN data. The future looks bright!

SN Cosmology with Euclid

With Duke undergrad Ava Bailey, we explored the idea of doing SN Ia cosmology with LSST and Euclid! We generated mock catalogues of NIR light curves from Euclid and combined them with simulated optical light curves from LSST. In this paper (Bailey, Vincenzi et al. 2022), we show how synergies between LSST and Euclid will help answering important questions like whether/why SNe Ia are better standard candles in the NIR and what is the role of dust in SN Ia standardization.

Testing Machine Learning SN classifiers

I spent quite a bit of time testing SN photometric classifiers based on Machine Learning algorithms! A robust testing of these classification algorithms is essential for cosmological analyses of photometric SN samples like the DES SN sample! Check out my results in these set of papers: Vincenzi et al. 2020 and Vincenzi et al. 2021.

A New library of Core-collapse templates

I built a new library of templates to simulate core-collapse SNe. You can download the templates (here). They are already built into SN simulation softwares like sncosmo or SNANA. For the nitty gritty details, take a look at the paper I wrote to release these new templates (Vincenzi et al. 2019).
