The Galaxies Formation and Evolution Group at CAB aims at providing a\u00a0global view of the processes of galaxy formation and evolution across\u00a0cosmic time. The research interests and expertise of the group members\u00a0cover a wide range of topics that are generally attacked\u00a0observationally with a multiwavelength approach. The group routinely\u00a0collects, analyzes, and publishes astronomical data from radio and\u00a0millimetric to infrared, optical and X-rays, making use of\u00a0state-of-the-art ground- and space-based facilities. The deep\u00a0expertise of group members across the electromagnetic spectrum enables\u00a0us to attack observationally, and to interpret theoretically, a very\u00a0broad range of physical phenomena and their interaction:\u00a0interacting\/merging galaxies, superwinds and feedback, gas outflows from millimteric and infrared to optical and X-rays, as well as the\u00a0nuclear activity and its relation with the overall host\u00a0properties.<\/p>\n

The scientific research carried out at CAB covers most of the relevant\u00a0aspects of galaxy formation and evolution. The group has a great\u00a0expertise in observational studies of massive star-formation in both\u00a0nearby and distant luminous star-forming galaxies using, for instance,\u00a0the Lyman alpha emission as a tracer of star formation\u00a0processes. Integral-field spectroscopy of luminous and ultra-luminous\u00a0infrared galaxies in the near infrared is routinely used to\u00a0differentiate the different ionization mechanisms of the interstellar\u00a0medium (supernovae, young stars, Active Galactic Nuclei …) over a\u00a0very broad range of luminosities and to characterize the galaxy\u00a0properties. Neutral and ionized gas outflows, their kinematics, their\u00a0effect on the star-formation rate and thus on the overall galaxy\u00a0evolution, are also obsevationally studied in the optical and\u00a0infrared.<\/p>\n

Any theoretical model of galaxy evolution must take into account the\u00a0presence of a central super-massive black hole which, when active,\u00a0reveals itself as an Active Galactic Nucleus (AGN). AGN observations\u00a0are carried out at all wavelengths at CAB. Radio observations are used\u00a0to shed light on the impact of radio jets on the interstellar medium,\u00a0linking the mechanical energy release by the central black hole to\u00a0galaxy evolution via radio-mode feedback. This is complemented by\u00a0optical studies of AGN-driven gas outflows which are sensitive to the\u00a0so-called radiative-mode of AGN feedback. The power of infrared data\u00a0is fully exploited not only to select and characterize distant AGN in\u00a0combination with multiwavelength data, but also to understand the\u00a0physical nature of the obscuring dusty circumnuclear material (the so\u00a0called clumpy, dusty torus) and its relation with nuclear star\u00a0formation, molecular gas, and inflows\/outflows. X-ray data complement\u00a0this research shedding light on the innermost regions of the accretion\u00a0flow around super-massive black holes, as well as on the AGN\u00a0surroundings from sub-pc (e.g. AGN winds and outflows, obscuring\u00a0matter …) to kpc scales (extended hot gas).<\/p>\n

The group is also heavily involved in technological\u00a0projects of future astronomical instrumentation both in space and on\u00a0the ground in the framework of the European Space Agency and the European Southern\u00a0Observatory programs. They participate in the instrument teams of the\u00a0MIRI and NiRSpec instruments for the James Webb Space Telescope\u00a0(JWST), and they are involved in the preparation of the first science\u00a0programs to be carried out with the JWST. Members of the group also\u00a0take part in the team responsible for the development of HARMONI, a\u00a0first-light instrument of the European Extremely Large Telescope\u00a0(E-ELT). Group members also participate to the definition of the next\u00a0ESA large X-ray observatory Athena both at the scientific and hardware\u00a0levels (X-IFU instrument), as well as in other space-based international projects\u00a0projects that are still at the ESA selection stage.<\/p>\n","protected":false},"excerpt":{"rendered":"
