The NIVARIA-Local Group simulations: Unveiling the origin of rotation curve diversity in dwarf galaxies and its connection to galaxy morphology
A. Contreras-Santos, A. Di Cintio, A. Negri +7
Dwarf galaxies exhibit a large diversity in rotation curve shapes, challenging galaxy formation models within the CDM paradigm. We present NIVARIA-LG, a new suite of cosmologica…
Disentangling the assembly of the central and diffuse stellar components in galaxy clusters through dynamical friction and tidal stripping
Frazer R. Pearce, Steven P. Bamford, Garreth Martin +7
In galaxy clusters, it is common to conceptually distinguish the central, brightest cluster galaxy (BCG) from the more diffuse intracluster light (ICL). So far, however, this disti…
HI-bearing dark galaxies predictions from constrained Local Group simulations: how many and where to find them
Guacimara García-Bethencourt, Arianna Di Cintio, Sébastien Comerón +7
Dark galaxies are small, DM-dominated halos whose gas remains in hydrostatic and thermal equilibrium and has never formed stars. They are of particular interest because they repres…
The origin of the intra-cluster light in The Three Hundred simulations
A. Contreras-Santos, A. Knebe, W. Cui +9
We investigate the origin and formation mechanisms of the intra-cluster light (ICL) in The Three Hundred simulations, a set of 324 hydrodynamically resimulated massive galaxy clust…
The life and times of dark matter haloes: what will I be when I grow up?
Julian Onions, Frazer Pearce, Alexander Knebe +6
Are the most massive objects in the Universe today the direct descendants of the most massive objects at higher redshift? We address this question by tracing the evolutionary histo…
The intracluster light as an estimator of the cluster mass profile
Isaac Alonso Asensio, Ana Contreras-Santos
Context. The intracluster light (ICL) comprises stars that are not bound to individual galaxies within a galaxy cluster, and it provides insights into the cluster mass distribution…
Stellar stripping efficiencies of satellites in numerical simulations: the effect of resolution, satellite properties and numerical disruption
G. Martin, F. R. Pearce, N. A. Hatch +3
The stellar stripping of satellites in cluster haloes is understood to play an important role in the production of intracluster light. Increasingly, cosmological simulations have b…
The Three Hundred project: Radio luminosity evolution from merger-induced shock fronts in simulated galaxy clusters
Sebastián E. Nuza, Matthias Hoeft, Ana Contreras-Santos +2
Galaxy cluster mergers are believed to generate large-scale shock waves that are ideal sites for electron acceleration. We compute radio emission light curves for galaxy group and…
Reconsidering the dynamical states of galaxy clusters using PCA and UMAP
Roan Haggar, Federico De Luca, Marco De Petris +10
Numerous metrics exist to quantify the dynamical state of galaxy clusters, both observationally and within simulations. Many of these correlate strongly with one another, but it is…
Identifying Galaxy Cluster Mergers with Deep Neural Networks using Idealized Compton-y and X-ray maps
Ashleigh R. Arendt, Yvette C. Perrott, Ana Contreras-Santos +3
We present a novel approach to identify galaxy clusters that are undergoing a merger using a deep learning approach. This paper uses massive galaxy clusters spanning $0 \leq z \leq…
Characterising the intra-cluster light in The Three Hundred simulations
Ana Contreras-Santos, Alexander Knebe, Weiguang Cui +7
We characterise the intra-cluster light (ICL) in ensembles of full-physics cluster simulations from The Three Hundred project, a suite of 324 hydrodynamical resimulations of cluste…
Galaxy pairs in The Three Hundred simulations II: studying bound ones and identifying them via machine learning
Ana Contreras-Santos, Alexander Knebe, Weiguang Cui +5
Using the data set of The Three Hundred project, i.e. 324 hydrodynamical resimulations of cluster-sized haloes and the regions of radius 15 Mpc around them, we study galaxy…
A study of the hydrostatic mass bias dependence and evolution within The Three Hundred clusters
Giulia Gianfagna, Elena Rasia, Weiguang Cui +4
We use a set of about 300 simulated clusters from The Three Hundred Project to calculate their hydrostatic masses and evaluate the associated bias by comparing them with the true c…
Galaxy pairs in The Three Hundred simulations: a study on the performance of observational pair-finding techniques
Ana Contreras-Santos, Alexander Knebe, Weiguang Cui +5
Close pairs of galaxies have been broadly studied in the literature as a way to understand galaxy interactions and mergers. In observations they are usually defined by setting a ma…
\textsc{The Three Hundred} project: The \textsc{Gizmo-Simba} run
Weiguang Cui, Romeel Dave, Alexander Knebe +22
We introduce \textsc{Gizmo-Simba}, a new suite of galaxy cluster simulations within \textsc{The Three Hundred} project. \textsc{The Three Hundred} consists of zoom re-simulations o…
The Three Hundred project: galaxy cluster mergers and their impact on the stellar component of brightest cluster galaxies
Ana Contreras-Santos, Alexander Knebe, Frazer Pearce +10
Using the data set of The Three Hundred project, i.e. a suite of 324 hydrodynamical resimulations of cluster-sized haloes, we study galaxy cluster mergers and their effect on colou…
