TL;DR: In this article, the authors demonstrate that highly accurate joint redshift-stellar mass probability distribution functions (PDFs) can be obtained using the Random Forest (RF) machine learning (ML) algorithm, even with few photometric bands available.
Journal ArticleDOI
The structure of small interstitial clusters in b.c.c. metals modelled with N-body potentials
J. M. Harder,David Bacon +1 more
TL;DR: In this paper, the properties of clusters of a small number (≤7) of self-interstitials in bodycentred-cubic transition metals have been studied by computer simulation using model interatomic potentials of the embedded-atom type.
Journal ArticleDOI
Measuring dark matter substructure with galaxy–galaxy flexion statistics
TL;DR: In this paper, a method to constrain substructure properties using the variance of weak gravitational flexion in a galaxy-galaxy lensing context is proposed, which is a statistical method, requiring many foreground-background pairs of galaxies.
Journal ArticleDOI
On the validity of the Born approximation for weak cosmic flexions
Björn Malte Schäfer,Björn Malte Schäfer,Lavinia Heisenberg,Lavinia Heisenberg,Angelos Fotios Kalovidouris,David Bacon +5 more
TL;DR: In this paper, the effect of dropping the Born approximation and taking lens-lens couplings into account, for weak lensing effects up to second order (cosmic flexion), by making a perturbative expansion in the light path is examined.
Journal ArticleDOI

TL;DR: In this article, a study of the population of bright early-type dwarfs in the multiple-cluster system Abell 901/902 is presented, where the authors use data from the STAGES survey and COMBO-17 to investigate the relation between the color and structural properties of the dwarfs and their location in the cluster.
