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…
The BUFFALO HST Survey
Charles L. Steinhardt, Mathilde Jauzac, Ana Acebron +91
The Beyond Ultra-deep Frontier Fields and Legacy Observations (BUFFALO) is a 101 orbit + 101 parallel Cycle 25 Hubble Space Telescope Treasury program taking data from 2018-2020. B…
