Triaxiality in galaxy clusters: Mass versus Potential reconstructions
Sebastian Stapelberg, Céline Tchernin, Damaris Hug +2
Accounting for the triaxial shapes of galaxy clusters will become important in the context of upcoming cosmological surveys. We show that, compared to the gas density distribution,…
Characterizing galaxy clusters by their gravitational potential: systematics of cluster potential reconstruction
C. Tchernin, E. T. Lau, S. Stapelberg +2
Context. Biases in mass measurements of galaxy clusters are one of the major limiting systematics in constraining cosmology with clusters. Aims. We aim to demonstrate that the syst…
EasyCritics II. Testing its efficiency: new gravitational lens candidates in CFHTLenS
M. Carrasco, S. Stapelberg, M. Maturi +3
We report the results of , a fully automated algorithm for the efficient search of strong-lensing (SL) regions in wide-field surveys, applied to the Canada-France-Hawa…
EasyCritics I: Efficient detection of strongly-lensing galaxy groups and clusters in wide-field surveys
Sebastian Stapelberg, Mauricio Carrasco, Matteo Maturi
We present EasyCritics, an algorithm to detect strongly-lensing groups and clusters in wide-field surveys without relying on a direct recognition of arcs. EasyCritics assumes that…
