The Bayesian Origin Reconstruction from Galaxies (BORG) algorithm provides a Bayesian framework to recover the dark matter field through forward modeling of structure formation, accounting for the nonlinear evolution of the velocity field. In this talk, I will present applications of BORG to the ZTF DR2.5 supernova sample, as well as results from realistic ZTF supernova simulations,...

Observations of the Universe indicate that approximately 95% of its content consists of the enigmatic components known as dark matter and dark energy. Understanding the nature of these entities is crucial for elucidating the evolutionary history of the Universe and for testing the validity of General Relativity. One of the most promising approaches to achieving this understanding is through...

We develop a novel approach to constrain the Hubble parameter $H_0$ and the primordial power spectrum amplitude $A_\mathrm{s}$ using type Ia supernovae (SNIa) data. By considering SNIa as tracers of the peculiar velocity field, we can model their distance and their covariance as a function of cosmological parameters without the need of calibrators like Cepheids; this yields a new independent...

The universe we observe today is dotted with galaxy clusters separated by vast voids, in sharp contrast to its initial state, which was nearly uniform with only minor density fluctuations. The evolution from this early uniformity to today's complex structure of galaxies is a profound transformation, with many intermediate processes still unexplained. In this talk, I will explore this...

The Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity Survey aims to provide measurements of the growth rate of structure and the Hubble constant in our local universe. To do so the survey, over the course of its 5 years of operations, aims to measure peculiar velocities for over 186,000 galaxies using both the Fundamental Plane and Tully Fisher relations. In this talk I will...

The Peculiar Velocity (PV) Survey of the Dark Energy Spectroscopic Instrument (DESI) is a secondary targeting program designed to carry out systematic measurements of peculiar motion at z < 0.2. The DESI PV Survey combines the spectroscopic galaxy redshifts recorded by DESI with standardizable distance measurements from Type Ia supernovae and elliptical and spiral galaxies in the DESI Bright...
