“Spectroscopic Surveys with the ELT: A Gigantic Step into the Deep Universe”

  Fecha de comienzo: 17/10/2017

  Fecha de finalización: 20/10/2017

Lugar: Palacio de Congresos de Toledo

Organizador: Jesús Gallego (UCM)

Descripción: (información disponible solo en inglés)

Scientific Rationale:
The European Extremely Large Telescope (E-ELT) will be the world’s largest optical/IR facility for at least a generation. It will have an immense collecting area, equivalent to gathering together all the current large telescopes in use today. Multi-object spectroscopy will be a key capability of the observatory, immediately able to harness its unprecedented sensitivity to deliver unique surveys which address a broad range of important topics in contemporary astrophysics.

The conceptual design of MOSAIC, a powerful multi-object spectrograph for the E-ELT, will conclude in late 2017. The design combines high-multiplex near-IR and visible spectroscopy, together with AO-corrected spectroscopy in the near-IR that exploits the fantastic angular resolution of the E-ELT across a large field of view. These capabilities will enable MOSAIC to tackle fundamental questions that are simply out of reach of other facilities. In cosmology, MOSAIC will lift the veil on how matter is distributed in distant galaxy haloes, including dark matter and missing baryons. It will also result in a leap forward in our uepoch of reionisation, the most exhaustive dynamical survey of distant galaxies ever undertaken and the detailed study of the stellar populations.

This colloquium is timed to discuss the scientific opportunities of surveys with MOSAIC, focussing in particular on simulated performances from the conceptual design. It will also take stock of other developments that will influence surveys envisaged for the late 2020s.

Scientific topics covered by the colloquium will include:

  • Probing the stellar populations at the heart of the Milky Way
  • Dissecting the different structural components of the Milky Way
  • Unravelling the stellar components of galaxies in the Local Volume
  • Spectroscopy of luminous stars far beyond the Local Group
  • Evolution/universality of the initial mass function
  • Properties of high-z dwarfs and their role in galaxy assembly
  • Constraints on the dark matter properties of high-z galaxies
  • Dynamical properties and formation of galaxies
  • Tomography of the high-redshift intergalactic medium
  • Evolution and baryon content of galaxy halos
  • Surveys of high-z AGN
  • Spectroscopy of first-light galaxies & the era of reionisation
