Machine Learning and Cosmological Simulations II: Hydrodynamical Simulations [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We extend a machine learning (ML) framework presented previously to model galaxy formation and evolution in a hierarchical universe using N-body + hydrodynamical simulations.

Hydrodynamical simulations of Pinwheel nebula WR 104 [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractPinwheel Nebulae are colliding wind binaries (CWB) composed of a Wolf-Rayet star and an early-type star. We first compare our simulations to analytic solutions for CWB. Then we perform large scale 2D simulations of the particular system WR 104.

Gravitational lenses in hydrodynamical simulations [PDF]
Proceedings of the International Astronomical Union, 2022 AbstractThe gravitational lensing signal produced by a galaxy or a galaxy cluster is determined by its total matter distribution, providing us with a way to directly constrain their dark matter content. State-of-the-art numerical simulations successfully reproduce many observed properties of galaxies and can be used as a source of mock observations and

Hydrodynamical Simulations of Black Hole Binary Formation in AGN Disks [PDF]
The Astrophysical Journal Letters, 2023 We study close encounters between two single black holes (BHs) embedded in an AGN disk using a series of global 2D hydrodynamics simulations. We find that when the disk density is sufficiently high, bound BH binaries can be formed by the collision of ...

Inhomogeneous Reionization Models in Cosmological Hydrodynamical Simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2019 In this work we present a new hybrid method to simulate the thermal effects of the reionization in cosmological hydrodynamical simulations. The method improves upon the standard approach used in simulations of the intergalactic medium (IGM) and galaxy ...

FLAMINGO: calibrating large cosmological hydrodynamical simulations with machine learning. [PDF]
Mon Not R Astron Soc, 2023 To fully take advantage of the data provided by large-scale structure surveys, we need to quantify the potential impact of baryonic effects, such as feedback from active galactic nuclei (AGN) and star formation, on cosmological observables.

Ring galaxies in the EAGLE hydrodynamical simulations [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We study the formation and evolution of ring galaxies in the Evolution and Assembly of GaLaxies and their Environments (EAGLE) simulations. We use the largest reference model Ref-L100N1504, a cubic cosmological volume of 100 cMpc on a side, to identify and characterize these systems through cosmic time.

Implications of hydrodynamical simulations for the interpretation of direct dark matter searches [PDF]
, 2017 In recent years, realistic hydrodynamical simulations of galaxies like the Milky Way have become available, enabling a reliable estimate of the dark matter density and velocity distribution in the Solar neighborhood.

Self-Consistent Modeling of Reionization in Cosmological Hydrodynamical Simulations [PDF]
, 2017 The ultraviolet background (UVB) emitted by quasars and galaxies governs the ionization and thermal state of the intergalactic medium (IGM), regulates the formation of high-redshift galaxies, and is thus a key quantity for modeling cosmic reionization ...
