Tidal shear and the consistency of microscopic Lagrangian halo approaches
Vincent Desjacques, Donghui Jeong, Fabian Schmidt
We delineate the conditions under which the consistency relation for the non-Gaussian bias and the universality of the halo mass function hold in the context of microscopic Lagrang…
The impact of ultra-light axion self-interactions on the large scale structure of the Universe
Vincent Desjacques, Alex Kehagias, Antonio Riotto
Ultra-light axions have sparked attention because their tiny mass eV, which leads to a Kiloparsec-scale de Broglie wavelength comparable to the size of dwarf galax…
Exploring Cosmic Origins with CORE: Survey requirements and mission design
J. Delabrouille, P. de Bernardis, F. R. Bouchet +200
Future observations of cosmic microwave background (CMB) polarisation have the potential to answer some of the most fundamental questions of modern physics and cosmology. In this p…
Shot noise and biased tracers: a new look at the halo model
Dimitry Ginzburg, Vincent Desjacques, Kwan Chuen Chan
Shot noise is an important ingredient to any measurement or theoretical modeling of discrete tracers of the large scale structure. Recent work has shown that the shot noise in the…
