COLOSSUS: A python toolkit for cosmology, large-scale structure, and dark matter halos
Benedikt Diemer
This paper introduces Colossus, a public, open-source python package for calculations related to cosmology, the large-scale structure (LSS) of matter in the universe, and the prope…
The Immitigable Nature of Assembly Bias: The Impact of Halo Definition on Assembly Bias
Antonia S. Villarreal, Andrew R. Zentner, Yao-Yuan Mao +6
Dark matter halo clustering depends not only on halo mass, but also on other properties such as concentration and shape. This phenomenon is known broadly as assembly bias. We explo…
Revisiting the bulge-halo conspiracy I: Dependence on galaxy properties and halo mass
Francesco Shankar, Alessandro Sonnenfeld, Gary A. Mamon +9
We carry out a systematic investigation of the total mass density profile of massive (Mstar>2e11 Msun) early-type galaxies and its dependence on galactic properties and host halo m…
The splashback radius of halos from particle dynamics. II. Dependence on mass, accretion rate, redshift, and cosmology
Benedikt Diemer, Philip Mansfield, Andrey V. Kravtsov +1
The splashback radius , the apocentric radius of particles on their first orbit after falling into a dark matter halo, has recently been suggested as a physically motiv…
The splashback radius of halos from particle dynamics. I. The SPARTA algorithm
Benedikt Diemer
Motivated by the recent proposal of the splashback radius as a physical boundary of dark matter halos, we present a parallel computer code for Subhalo and PARticle Trajectory Analy…
The Fabric of the Universe: Exploring the cosmic web in 3D prints and woven textiles
Benedikt Diemer, Isaac Facio
We introduce The Fabric of the Universe, an art and science collaboration focused on exploring the cosmic web of dark matter with unconventional techniques and materials. We discus…
Log-normal star formation histories in simulated and observed galaxies
Benedikt Diemer, Martin Sparre, Louis E. Abramson +1
Gladders et al. have recently suggested that the star formation histories (SFHs) of individual galaxies are characterized by a log-normal function in time, implying a slow decline…
