Biases in galaxy cluster velocity dispersion and mass estimates in the small number of galaxies regime
A. Ferragamo, J. A. Rubiño-Martín, J. Betancort-Rijo +3
We present a study of the statistical properties of three velocity dispersion and mass estimators, namely biweight, gapper and standard deviation, in the small number of galaxies r…
Optical validation and characterisation of Planck PSZ1 sources at the Canary Islands observatories. II. Second year of ITP13 observations
R. Barrena, A. Ferragamo, J. A. Rubiño-Martín +17
We report new galaxy clusters previously unknown included in the PSZ1 catalogue. The results here presented have been achieved during the second year of a 2-year observational prog…
Biases in the estimation of velocity dispersions and dynamical masses for galaxy clusters
Antonio Ferragamo, José Alberto Rubiño-Martín, Juan Betancort-Rijo +3
Using a set of 73 numerically simulated galaxy clusters, we have characterised the statistical and physical biases for three velocity dispersion and mass estimators, namely biweigh…
Optical validation and characterization of Planck PSZ2 sources at the Canary Islands observatories. II. Second year of LP15 observations
A. Aguado-Barahona, R. Barrena, A. Streblyanska +4
We present the second and last year of observations of our optical follow-up programme 128-MULTIPLE-16/15B (LP15 )at Roque de los Muchachos Observatory (La Palma), which has been d…
Optical validation and characterization of \Planck\ PSZ2 sources at the Canary Islands observatories. I. First year of LP15 observations
A. Streblyanska, A. Aguado-Barahona, A. Ferragamo +5
Using telescopes at the Canary Island observatories, we conducted the long-term observational programme 128-MULTIPLE-16/15B (LP15), a large and complete optical follow-up campaign…
