Ongoing collaborations

  • Galaxy Cluster Evolution Survey (GLACE)

An ESO/GTC large program observing clusters in the redshift range from 0.4 to 1.2 using the Tunable Filter mode of OSIRIS at GTC, together with data from infrared observatories like Herschel and Spitzer. Done in collaboration with IAC, IRAM, IFCA, CAB and IAA.

  • OSIRIS Tunable Emission Line Object Survey (OTELO)

A pencil bean survey in an area of the extended GROTH field aiming to detect emission line galaxies and study their characteristics and evolution across the cosmic times. Done in collaboration with IAC, IRAM, IFCA, CAB and IAA.

  • Lockman SpReSO survey.

A deep spectroscopic survey in the Lockman hole aiming to analyse the full spectra of galaxies in a wide range of redshifts. Done in collaboration with IA-UNAM, IAC, IRAM, IFCA, CAB and IAA.

  • Environment Driven Galaxy Evolution (EDGE)

A study of low surface brightness sources in a sample of galaxy clusters in the 0.18 - 0.45 redshift range. The main goal of the project is to detect the influence of the environment in the star formation rate and/or AGN activity in their earliest stages. Done in collaboration with UCM, CEFCA and U. Valladolid.

  • Machine learning applied to cluster galaxy classification. (ML-GC)
  • A project to develop machine learning techniques to establish cluster memberships of galaxies using the Hubble Frontier Fields data and X-ray extended emission maps, mainly from XMM-Newton. Done in collaboration with CEFCA, U. Valladolid and IFCA.
