Non-halo structures and their effects on gravitationally lensed galaxies
Baptiste Jego, Giulia Despali, Tamara Richardson +1
While the CDM model succeeds on large scales, its validity on smaller scales remains uncertain. Recent works suggest that non-halo dark matter structures, such as filaments and…
Measuring the Tidal Response of Structure Formation: Anisotropic Separate Universe Simulations using TreePM
Jens Stücker, Andreas. S. Schmidt, Simon D. M. White +2
We present anisotropic "separate universe" simulations which modify the N-body code Gadget-4 in order to represent a large-scale tidal field through an anisotropic expansion factor…
Cosmological parameter estimation via iterative emulation of likelihoods
Marcos Pellejero-Ibañez, Raul E. Angulo, Giovanni Aricó +3
The interpretation of cosmological observables requires the use of increasingly sophisticated theoretical models. Since these models are becoming computationally very expensive and…
Simulating the Complexity of the Dark Matter Sheet I: Numerical Algorithms
Jens Stücker, Oliver Hahn, Raul E. Angulo +1
At early times dark matter has a thermal velocity dispersion of unknown amplitude which, for warm dark matter models, can influence the formation of nonlinear structure on observab…
