An empirical study of pretrained representations for few-shot classification
Tiago Ramalho, Thierry Sousbie, Stefano Peluchetti
Recent algorithms with state-of-the-art few-shot classification results start their procedure by computing data features output by a large pretrained model. In this paper we system…
Tracing the cosmic web
Noam I Libeskind, Rien van de Weygaert, Marius Cautun +27
The cosmic web is one of the most striking features of the distribution of galaxies and dark matter on the largest scales in the Universe. It is composed of dense regions packed fu…
The VIMOS Public Extragalactic Redshift Survey (VIPERS): Galaxy segregation inside filaments at
N. Malavasi, S. Arnouts, D. Vibert +42
We present the first quantitative detection of large-scale filamentary structure at in the large cosmological volume probed by the VIMOS Public Extragalactic Redshif…
ColDICE: a parallel Vlasov-Poisson solver using moving adaptive simplicial tessellation
Thierry Sousbie, Stéphane Colombi
Resolving numerically Vlasov-Poisson equations for initially cold systems can be reduced to following the evolution of a three-dimensional sheet evolving in six-dimensional phase-s…
Vlasov versus N-body: the Hénon sphere
S. Colombi, T. Sousbie, S. Peirani +2
We perform a detailed comparison of the phase-space density traced by the particle distribution in Gadget simulations to the result obtained with a spherical Vlasov solver using th…
Dancing in the dark: galactic properties trace spin swings along the cosmic web
Yohan Dubois, Christophe Pichon, Charlotte Welker +30
A large-scale hydrodynamical cosmological simulation, Horizon-AGN, is used to investigate the alignment between the spin of galaxies and the cosmic filaments above redshift 1.2. Th…
