In this paper, I study the impact of intrinsic scatter of SNe Ia on the measurement of \(f\sigma_8\). This study is done through the simulation of the full low-z LSST SNe Ia sample for different intrinsic scatter models. We found that the most realistic model of intrinsic scatter causes non-Gaussianities in the Hubble diagram residuals, resulting in a bias on \(f\sigma_8\).

This paper is part of the second data release of ZTF SNe Ia. In this paper, I study the impact of the peculiar velocity (PV) systematics on the Hubble diagram of the ZTF SN Ia DR2 sample. We show that not taking into account the full PV covariance matrix can lead to a slight underestimation of the error on the Hubble constant \(H_0\)and could shift its value by \(∼\) 1 km s\(^-1\).

This paper is the main publication of my thesis. In this paper, I present my work to prepare for the future measurement of the growth rate of structure (\(f\sigma_8\)) from ZTF SN Ia data. I describe my realistic simulation of the ZTF SN Ia sample and, using these simulations, I study the biases and systematics that can affect the measurement of \(f\sigma_8\). I show that using SN Ia data from the full 6 years of the ZTF II sample with a cut at a redshift of \(z < 0.06\)to avoid selection due to magnitude limit, we can expect an unbiased measurement of \(f\sigma_8\)with an error of \(∼19%\).

-
This paper introduces the WHALES survey that is discovering SNe Ia nearby the Shapley Supercluster. I contributed to simulations and forecasts described in this paper.

This publication introduces the Dark Energy Bedrock All-Sky Supernova (DEBASS) low-\(z\)survey. The paper gives an overview of the survey, examines systematic such as photometric calibration and selection effects, presents simulations, and provides forecasts for future cosmological analysis. I was actively involved in the simulation and forecast sections, and in the writing process

This paper presents a simulation-based forecast for the measurement of the growth rate of structure (\(f\sigma_8\)) with the Rubin-LSST survey. It shows that the full constraining power of the Rubin-LSST SNe Ia sample will enable a constraint at the \(\sim10%\)level in the redshift range \(0.02 < z < 0.14\). I participated in the development of the simulation and analysis code used in this publication. I was also involved in the writing and review process.

This paper presents the FLIP Python library. This library is based on codes developed during my PhD and proposes a more general framework for the constraint of the growth rate of structure. I actively participated in the development of FLIP and in the writing of this paper.
-
In this paper, we used SNe Ia data and the Uchuu UniverseMachine simulation to study the improvement on the SNe Ia Hubble diagram that we can expect from averaging redshift over galaxy groups of SN Ia hosts. I ran the simulations and was actively involved in the analysis.
