A population of faint, old, and massive quiescent galaxies at 3 < z < 4 revealed by JWST NIRSpec Spectroscopy
Themiya Nanayakkara, Karl Glazebrook, Colin Jacobs +13
Here we present a sample of 12 massive quiescent galaxy candidates at z~3-4 observed with the James Webb Space Telescope (JWST) Near Infrared Spectrograph (NIRSpec). These galaxies…
The Hateful Eight: Connecting Massive Substructures in Galaxy Clusters like Abell 2744 to their Dynamical Assembly State using the Magneticum Simulations
Lucas C. Kimmig, Rhea-Silvia Remus, Klaus Dolag +1
Substructures are known to be good tracers for the dynamical states and recent accretion histories of the most massive collapsed structures in the Universe, galaxy clusters. Observ…
Planes of Satellite Galaxies in the Magneticum Pathfinder Simulations
Pascal U. Förster, Rhea-Silvia Remus, Klaus Dolag +3
Planes of satellites are observed around many galaxies. However, these observations are still considered a point of tension for the CDM paradigm. We use the fully hydrodynamical…
A stream come true: Connecting tidal tails, shells, streams, and planes with galaxy kinematics and formation history
Lucas M. Valenzuela, Rhea-Silvia Remus
The rapidly improving quality and resolution of both low surface brightness observations and cosmological simulations of galaxies enables one to address the important question how…
The Young and the Wild: What happens to Protoclusters forming at z = 4?
Rhea-Silvia Remus, Klaus Dolag, Helmut Dannerbauer
Using one of the largest volumes of the hydrodynamical cosmological simulation suit Magneticum, we study the evolution of protoclusters identified at redshift = 4, with properties…
ΛCDM with baryons vs. MOND: the time evolution of the universal acceleration scale in the Magneticum simulations
Alexander C. Mayer, Adelheid F. Teklu, Klaus Dolag +1
MOdified Newtonian Dynamics (MOND) is an alternative to the standard Cold Dark Matter (CDM) paradigm which proposes an alteration of Newton's laws of motion at low accelerations, c…
