Modeling Biased Tracers at the Field Level
Marcel Schmittfull, Marko Simonović, Valentin Assassi +1
In this paper we test the perturbative halo bias model at the field level. The advantage of this approach is that any analysis can be done without sample variance if the same initi…

Efficient Evaluation of Cosmological Angular Statistics
Valentin Assassi, Marko Simonović, Matias Zaldarriaga
Angular statistics of cosmological observables are hard to compute. The main difficulty is due to the presence of highly-oscillatory Bessel functions which need to be integrated ov…
