cosmokdtree: a flexible OpenMP-parallelized k-d tree for computational astrophysics applications
Óscar Monllor-Berbegal, David Vallés-Pérez, Susana Planelles +1
Modern numerical astrophysics applications present a common demand for efficient spatial querying techniques, such as neighbor searches or density estimations over billions of reso…
The youth of the intracluster medium. I. A non-parametric characterisation of the gas and electron number density profiles of protoclusters
David Vallés-Pérez, Annalisa Bonafede, Klaus Dolag +3
Context. Protoclusters of galaxies are the earliest phase in the assembly of galaxy clusters and can provide invaluable information about plasma physics, cosmic magnetism, and cosm…
Magnetic fields at the dawn of structure formation I. The CARLA J1510+5958 proto-cluster
A. Pagliotta, A. Bonafede, C. Stuardi +4
Magnetic fields are a fundamental ingredient of the Universe, influencing the formation and evolution of cosmic structures. While magnetic fields in local galaxy clusters have been…
The eventful life journey of galaxy clusters. II. Impact of mass accretion on the thermodynamical structure of the ICM
David Vallés-Pérez, Susana Planelles, Vicent Quilis
Context. The internal structure of the intracluster medium (ICM) is tightly linked to the assembly history and physical processes in groups and clusters, but the role of recent acc…
The signature of major mergers on the hydrostatic mass bias of galaxy clusters
Isac Barranco-Llorca, David Vallés-Pérez, Susana Planelles +1
While galaxy cluster masses are fundamental cosmological observables, estimates based on intra-cluster medium observations rely on hydrostatic equilibrium, introducing a systematic…
AVISM: Algorithm for Void Identification in coSMology
Óscar Monllor-Berbegal, David Vallés-Pérez, Susana Planelles +1
Cosmic voids are key elements in our understanding of the large-scale structure of the Universe. They are crucial to constrain cosmological parameters, understand the structure for…
The eventful life journey of galaxy clusters. I. Impact of DM halo and ICM properties on their full assembly histories
David Vallés-Pérez, Susana Planelles, Vicent Quilis
Context. Galaxy clusters assemble over gigayears in a very anisotropic environment, which causes a remarkable diversity in their mass assembly histories (MAH). Aims. In this work,…
Turbulent Pressure Support in Galaxy Clusters -- Impact of the Hydrodynamical Solver
Frederick Groth, Milena Valentini, Ulrich P. Steinwandel +2
The amount of turbulent pressure in galaxy clusters is still debated, especially as for the impact of the dynamical state and the hydro-method used for simulations. We study the tu…
Vortex-p: a Helmholtz-Hodge and Reynolds decomposition algorithm for particle-based simulations
David Vallés-Pérez, Susana Planelles, Vicent Quilis +3
Astrophysical turbulent flows display an intrinsically multi-scale nature, making their numerical simulation and the subsequent analyses of simulated data a complex problem. In par…
Cosmic accretion shocks as a tool to measure the dark matter mass of galaxy clusters
David Vallés-Pérez, Vicent Quilis, Susana Planelles
Cosmological accretion shocks created during the formation of galaxy clusters are a ubiquitous phenomenon all around the Universe. These shocks, and their features, are intimately…
Density Fluctuations in the Intracluster Medium: An Attempt to Constrain Viscosity with Cosmological Simulations
Tirso Marin-Gilabert, Ulrich P. Steinwandel, Milena Valentini +2
The impact of viscosity in the Intracluster Medium (ICM) is still an open question in astrophysics. To address this problem, we have run a set of cosmological simulations of three…
The imprints of galaxy cluster internal dynamics on the Sunyaev-Zeldovich effect
Óscar Monllor-Berbegal, David Vallés-Pérez, Susana Planelles +1
Forthcoming measurements of the Sunyaev-Zeldovich (SZ) effect in galaxy clusters will dramatically improve our understanding of the main intra-cluster medium (ICM) properties and h…
On the choice of the most suitable indicator for the assembly state of dark matter haloes through cosmic time
David Vallés-Pérez, Susana Planelles, Óscar Monllor-Berbegal +1
The dynamical state and morphological features of galaxies and galaxy clusters, and their high-redshift precursors, are tightly connected with their assembly history, encoding cruc…
The halo finding problem revisited: a deep revision of the ASOHF code
David Vallés-Pérez, Susana Planelles, Vicent Quilis

Void replenishment: how voids accrete matter over cosmic history
David Vallés-Pérez, Vicent Quilis, Susana Planelles
Cosmic voids are underdense regions filling up most of the volume in the Universe. They are expected to emerge in regions comprising negative initial density fluctuations, and subs…
Troubled cosmic flows: turbulence, enstrophy and helicity from the assembly history of the intracluster medium
David Vallés-Pérez, Susana Planelles, Vicent Quilis
Both simulations and observations have shown that turbulence is a pervasive phenomenon in cosmic scenarios, yet it is particularly difficult to model numerically due to its intrins…
