We searched for isolated dark matter deprived galaxies within several state-of-the-art hydrodynamical simulations: Illustris, IllustrisTNG, EAGLE, and Horizon-AGN and found a handful of promising objects in all except Horizon-AGN. While our initial goal was to study their properties and evolution, we quickly noticed that all of them were located at the edge of their respective simulation boxes. After carefully investigating these objects using the full particle data, we concluded that they… Expand

Dark Matter Deficient Galaxies Produced via High-velocity Galaxy Collisions in High-resolution Numerical Simulations
The recent discovery of diffuse dwarf galaxies that are deficient in dark matter appears to challenge the current paradigm of structure formation in our Universe. We describe the numericalExpand
Dark matter-deficient dwarf galaxies form via tidal stripping of dark matter in interactions with massive companions
In the standard Lambda-CDM paradigm, dwarf galaxies are expected to be dark-matter-rich, as baryonic feedback is thought to quickly drive gas out of their shallow potential wells and quench starExpand


Dark-matter-deficient galaxies in hydrodynamical simulations
Low-mass galaxies are expected to be dark-matter-dominated even within their central regions. Recently, two observations reported two dwarf galaxies in a group environment with very little darkExpand
Dark matter stripping in galaxy clusters: a look at the stellar-to-halo mass relation in the Illustris simulation
Satellite galaxies in clusters represent a significant fraction of the global galaxy population, and because of the unusual dense environment they live in, their evolution is driven by mechanismsExpand
The EAGLE simulations of galaxy formation: Public release of particle data
This manual accompanies the release of the particle data for 24 simulations of the EAGLE suite of cosmological hydrodynamical simulations of galaxy formation by the virgo consortium. It describes howExpand
The ultra-diffuse galaxy NGC 1052-DF2 with MUSE
NGC 1052-DF2, an ultra-diffuse galaxy (UDG), has been the subject of intense debate. Its alleged absence of dark matter, and the brightness and number excess of its globular clusters (GCs) at anExpand
First results from the TNG50 simulation: the evolution of stellar and gaseous discs across cosmic time
We present a new cosmological, magnetohydrodynamical simulation for galaxy formation: TNG50, the third and final instalment of the IllustrisTNG project. TNG50 evolves 2 × 21603 dark matterExpand
First results from the TNG50 simulation: galactic outflows driven by supernovae and black hole feedback
We present the new TNG50 cosmological, magnetohydrodynamical simulation – the third and final volume of the IllustrisTNG project. This simulation occupies a unique combination of large volume andExpand
The ultra-diffuse galaxy NGC 1052-DF2 with MUSE: I. Kinematics of the stellar body
The so-called ultra-diffuse galaxy NGC 1052-DF2 was announced to be a galaxy lacking dark matter based on a spectroscopic study of its constituent globular clusters. Here we present the firstExpand
The IllustrisTNG simulations: public data release
Improvements and new functionality in the web-based API are described, including on-demand visualization and analysis of galaxies and halos, exploratory plotting of scaling relations and other relationships between galactic and halo properties, and a new JupyterLab interface that provides an online, browser-based, near-native data analysis platform enabling user computation with local access to TNG data, alleviating the need to download large datasets.
