Our main research areas are: the study of galaxy clusters (mass estimates, galaxy evolution ...), proto-clusters, gravitationally lensed sources and deep cosmological surveys in the far-infrared with Herschel, detection and characterization of galaxy clusters with Euclid, cosmology wth galaxy clusters and galaxy clustering.

The First Spanish Meeting on Galaxy Clusters was held at ESAC on 7 & 8 November 2019​​​​​​​

The active members of the galaxy clusters and cosmology group at ESAC in 2020 are :



  • René Laureijs (Euclid Project Scientist)
  • Rachana Bhatawdekar (ESA Research Fellow)

We are involved in several large international collaborations as :

from low-redshift to high redshift clusters as well as proto-clusters.

Former members: Miguel Sanchez-Portal (ESO), Irene Pintos-Castro (Univeristy of Toronto), Tim Rawle (ESA@STScI), Joana Santos, Maggie Lieu (University of  Nottintham), Ginebra Favole (EPFL, Lausane), Luca Conversi (ESRIN)

ESAC trainees: Sophia Milanov (2017), Matej Kosiba (2018), Ditlev Frickmann (2020)
