Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign
T. Shenar, J. Bodensteiner, M. Abdul-Masih +73
Massive stars at low metallicity (Z) play a central role in shaping the high-redshift Universe, yet their multiplicity remains poorly constrained. The Binarity at Low Metallicity (…

Renormalized Perturbation Theory at Field-level: the LSS bootstrap in GridSPT
Matteo Peron, Takahiro Nishimichi, Massimo Pietroni +1
We present a first step toward field-level cosmological inference beyond the standard CDM model, focusing on optimizing precision tests in the nonlinear regime of large-scale st…

Constraining Primordial Non-Gaussianity from Large Scale Structure with the Wavelet Scattering Transform
Matteo Peron, Gabriel Jung, Michele Liguori +1
We investigate the Wavelet Scattering Transform (WST) as a tool for the study of Primordial non-Gaussianity (PNG) in Large Scale Structure (LSS), and compare its performance with t…
