Non-spherical Cows: Introducing the Asphericity Parameter as a Measure of Accretion Geometry
Benjamin A. Seidel, Rhea-Silvia Remus, Lucas C. Kimmig +2
The outer regions of galactic halos represent the bridge connecting internal processes within the galaxy to the larger surrounding cosmic web. The gas in this bridge region is shap…
GREX-PLUS Science Book v2
PLUS Science Team, Shunsuke Baba, Sirio Belli +52
GREX-PLUS (Galaxy Reionization EXplorer and PLanetary Universe Spectrometer) is a mission candidate for a JAXA strategic L-class mission to be launched in the 2030s. Its primary sc…
Built to Rest: The Evolving Star-Forming Main Sequence Requires Episodic Quiescence or Late Assembly
Lucas C. Kimmig, Jesse van de Sande, Rhea-Silvia Remus +3
The star-forming main sequence of galaxies has now been observed out to redshifts of and beyond. However, it remains unclear how long typical galaxies remain on or near it…
A massive and evolved slow-rotating galaxy in the early Universe
Ben Forrest, Adam Muzzin, Danilo Marchesini +15
In the contemporary Universe, most galaxies are supported by ordered rotation, yet a significant subset of the most massive and quiescent systems are dominated by random stellar mo…
On the unique evolutionary mechanisms of massive quiescent galaxies in the epoch of reionisation
Harry George Chittenden, Karl Glazebrook, Themiya Nanayakkara +4
We investigate the evolutionary histories of a population of high mass, high redshift, quiescent galaxies in the cosmohydrodynamical simulation Thesan, studying the characteristic…
Encyclopedia Magneticum: Scaling Relations from Cosmic Dawn to Present Day
Klaus Dolag, Rhea-Silvia Remus, Lucas M. Valenzuela +10
Galaxy and halo scaling relations, connecting a broad range of parameters, are well established from observations. The origin of many of these relations and their scatter is still…
