The OpenGadget3 Code for Cosmological Simulations

Klaus Dolag, Geray S. Karademir, Luca Tornatore +28

We present the public release of OpenGadget3 (OG3), a substantially extended and re-organised version of the widely used Gadget-2/3 family of cosmological simulation codes. Since G…

Dianoga simulations of galaxy clusters and groups: Properties of the baryonic components

Stefano Borgani, Alice Damiano, Elena Rasia +12

We introduce the Dianoga set of cosmological simulations of galaxy clusters and groups, specifically aimed at studying the impact of the implementation of AGN feedback and star for…

Braginskii Viscosity in Cosmological Simulations of Galaxy Clusters: Implementation, Validation, and First Application

Tirso Marin-Gilabert, Ulrich P. Steinwandel, Milena Valentini +2

We present the implementation of an anisotropic viscosity solver within the magnetohydrodynamics (MHD) framework of the TreeSPH code OpenGadget3. The solver models anisotropic visc…

Characterizing the roles of transitory obscured phases and inner torus in shaping the fractions of obscured AGN at cosmic noon

Alba V. Alonso-Tetilla, Francesco Shankar, Fabio Fontanot +11

The origin of obscuration in Active Galactic Nuclei (AGN) is still a matter of contention. It is unclear whether obscured AGN are primarily due to line-of-sight effects, a transito…

Turbulence in Simulated Local Cluster Analogs: One-to-one comparisons between SLOW and XRISM/Hitomi

Frederick Groth, Milena Valentini, Benjamin A. Seidel +4

The XRISM Resolve X-ray spectrometer allows to gain detailed insight into gas motions of the intra cluster medium (ICM) of galaxy clusters. Current simulation studies focus mainly…

Hydrodynamic methods and sub-resolution models for cosmological simulations

Milena Valentini, Klaus Dolag

Cosmological simulations are powerful tools in the context of structure formation. They allow us to explore the assembly and clustering of dark matter halos, to validate or reject…

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…

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…

How non-thermal pressure impacts the modelling of star formation in galaxy formation simulations

Eirini Batziou, Ulrich P. Steinwandel, Klaus Dolag +1

In cosmological simulations of large-scale structure star formation and feedback in galaxies are modelled by so-called sub-grid models, that represent a physically motivated approx…

Simulating nearby disc galaxies on the main star formation sequence I. Bar formation and the building of the central gas reservoir

Pierrick Verwilghen, Eric Emsellem, Florent Renaud +14

Past studies have long emphasised the key role played by galactic stellar bars in the context of disc secular evolution, via the redistribution of gas and stars, the triggering of…

Dynamical friction and evolution of black holes in cosmological simulations: a new implementation in OpenGadget3

Alice Damiano, Milena Valentini, Stefano Borgani +5

We implement a sub-resolution prescription for the unresolved dynamical friction onto black holes (BHs) in the OpenGadget3 code. We carry out cosmological simulations of a volume o…

Simulating the LOcal Web (SLOW) II: Properties of local galaxy clusters

Elena Hernández-Martínez, Klaus Dolag, Benjamin Seidel +6

This is the second paper in a series presenting the results from a 500 Mpc large constrained hydro-dynamical simulation of the local Universe (SLOW). The initial conditions…

Supermassive black hole spin evolution in cosmological simulations with OpenGadget3

Luca Sala, Milena Valentini, Veronica Biffi +1

Mass and spin of massive black holes (BHs) at the centre of galaxies evolve due to gas accretion and mergers with other BHs. Besides affecting e.g. the evolution of relativistic je…

Probing the roles of orientation and multi-scale gas distributions in shaping the obscuration of Active Galactic Nuclei through cosmic time

Alba V. Alonso-Tetilla, Francesco Shankar, Fabio Fontanot +14

The origin of obscuration in Active Galactic Nuclei (AGN) is still an open debate. In particular, it is unclear what drives the relative contributions to the line-of-sight column d…

LEM All-Sky Survey: Soft X-ray Sky at Microcalorimeter Resolution

Ildar Khabibullin, Massimiliano Galeazzi, Akos Bogdan +23

The Line Emission Mapper (LEM) is an X-ray Probe with with spectral resolution ~2 eV FWHM from 0.2 to 2.5 keV and effective area >2,500 cm at 1 keV, covering a 33 arcmin diamet…
