The caustic method applied to The Three Hundred: Prospects for the upcoming CATARSIS and other surveys
We investigate the expected uncertainties involved when recovering galaxy cluster mass profiles from upcoming spectroscopic survey data, based on The Three Hundred Project. Using the caustic technique, which leverages galaxy positions and line-of-sight velocities, we assessed the systematic errors introduced by assumptions regarding velocity anisotropy and demonstrated how an iterative correction method can minimize these errors. We also assessed the impact of survey magnitude limits on cluster mass estimates, highlighting potential biases across different observational strategies We focused the analysis on our own CATARSIS survey, which is set to obtain redshift measurements for all galaxies with magnitudes of m_ AB, r < 22 within 2timesR_ 200,c for 16 galaxy clusters with redshifts of 0.14 < z < 0.27. We used the future 8,arcmin2 field-of-view TARSIS integral-field spectrograph of the Calar Alto 3.5-m telescope. These data will enable us to mitigate systematic errors in the determination of density profiles. CATARSIS is aimed at enhancing the precision of mass profile estimates by deepening our understanding of the dynamical states and physical characteristics of galaxy clusters.
