Hydrodynamical simulations of galaxy formation with non-Gaussian initial conditions [PDF]
, 2023 International audienceCollisionless simulations of structure formation with significant local primordial non-Gaussianities at Mpc scales have shown that a non-Gaussian tail favouring underdensities, with a negative $f_{\rm NL}$ parameter, can ...

The three hundred project: Substructure in hydrodynamical and dark matter simulations of galaxy groups around clusters [PDF]
, 2021 Dark matter-only simulations are able to produce the cosmic structure of a Lambda cold dark matter universe, at a much lower computational cost than more physically motivated hydrodynamical simulations.

Substructures in hydrodynamical cluster simulations [PDF]
, 2009 The abundance and structure of dark matter subhaloes have been analysed extensively in recent studies of dark-matter-only simulations, but comparatively little is known about the impact of baryonic physics on halo substructures.

Hydrodynamical Simulations of Extragalactic Jets [PDF]
, 2011 Hydrodynamical simulations have played an important role in the understanding of extragalactic jets since the late seventies. In this talk, recent simulations of jets in the relativistic regime are reviewed.

The FLAMINGO project: cosmological hydrodynamical simulations for large-scale structure and galaxy cluster surveys [PDF]
, 2023 We introduce the Virgo Consortium's FLAMINGO suite of hydrodynamical simulations for cosmology and galaxy cluster physics. To ensure the simulations are sufficiently realistic for studies of large-scale structure, the subgrid prescriptions for stellar ...

Hydrodynamical simulations of massive stars collisions [PDF]
, 2023 openSince the detection of gravitational waves traveling through our universe, a new field of astrophysics has opened up, and with it many hypotheses and theoretical predictions have been put to the test. This is the case of the pair-instability mass gap

Comparing galactic satellite properties in hydrodynamical and N-body simulations [PDF]
, 2011 In this work, we examine the different properties of galactic satellites in hydrodynamical and pure dark matter simulations. We use three pairs of simulations (collisional and collisionless) starting from identical initial conditions.

Semi-analytical and hydrodynamical simulations of planet induced kinks [PDF]
, 2022 Planets embedded in protoplanetary discs excite density waves that propagate in the disc forming a spiral wake and perturbing the gas velocity field. Such perturbations are now routinely observed with ALMA (so-called 'kinks' and 'doppler-flips'). However,
