The ACCEL2 project: Simulating Lyman-α forest in large-volume hydrodynamical simulations [PDF]
Monthly notices of the Royal Astronomical SocietyCosmological information is usually extracted from the Lyman-α (Lyα) forest correlations using only either large-scale information interpreted through linear theory or using small-scale information interpreted by means of expensive hydrodynamical ...

First Constraints on Fuzzy Dark Matter from Lyman-α Forest Data and Hydrodynamical Simulations. [PDF]
Physical Review Letters, 2017 We present constraints on the masses of extremely light bosons dubbed fuzzy dark matter (FDM) from Lyman-α forest data. Extremely light bosons with a de Broglie wavelength of ∼1 kpc have been suggested as dark matter candidates that may resolve some of ...

The El Gordo Galaxy Cluster Challenges ΛCDM for Any Plausible Collision Velocity
The Astrophysical Journal, 2023 El Gordo (ACT-CL J0102-4915) is an extraordinarily large and bright galaxy cluster collision. In a previous study, we found that El Gordo is in 6.2 σ tension with the Λ cold dark matter (ΛCDM) standard model when assuming the nominal mass and infall ...

Monthly notices of the Royal Astronomical Society, 2020 Hydrodynamical simulations of galaxy formation and evolution attempt to fully model the physics that shapes galaxies. The agreement between the morphology of simulated and real galaxies, and the way the morphological types are distributed across galaxy

Thermal and non-thermal dust sputtering in hydrodynamical simulations of the multiphase interstellar medium [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We study the destruction of interstellar dust via sputtering in supernova (SN) shocks using three-dimensional hydrodynamical simulations. With a novel numerical framework, we follow both sputtering and dust dynamics governed by direct collisions, plasma ...

Overcast on Osiris: 3D radiative-hydrodynamical simulations of a cloudy hot Jupiter using the parametrized, phase-equilibrium cloud formation code EddySed [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present results from 3D radiative-hydrodynamical simulations of HD 209458b with a fully coupled treatment of clouds using the EddySed code, critically, including cloud radiative feedback via absorption and scattering. We demonstrate that the thermal

The Astrophysical Journal, 2023 Recent simulations find that hot gas accretion onto compact accretors is often highly turbulent and diskless, and shows a power-law density profile with slope α _ρ ≈ −1.

Stellar feedback from HMXBs in cosmological hydrodynamical simulations [PDF]
, 2015 We explored the role of X-ray binaries composed by a black hole and a massive stellar companion (BHXs) as sources of kinetic feedback by using hydrodynamical cosmological simulations. Following previous results, our BHX model selects low metal-poor stars

Hydrodynamical simulations and similarity relations for eruptive mass-loss from massive stars [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Motivated by the eruptive mass loss inferred from Luminous Blue Variable (LBV) stars, we present 1D hydrodynamical simulations of the response from sudden energy injection into the interior of a very massive ($100 \, M_\odot$) star.

Coupling 1D stellar evolution with 3D-hydrodynamical simulations on-the-fly II: stellar evolution and asteroseismic applications [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Models of stellar structure and evolution are an indispensable tool in astrophysics, yet they are known to incorrectly reproduce the outer convective layers of stars. In the first paper of this series, we presented a novel procedure to include the mean
