Two NANOCOSMOS members, Prof. José Cernicharo and Dr. Javier R. Goicoechea gave two invited talks at this workshop in Poland. José Cernicharo showed the NANOCOSMOS latests results from the ALMA observations of the archetypical AGB carbon-star IRC+10216. The NANOCOSMOS team has published 4 articles (see publications) on these results (including IRAM observations) and new exciting results are expected for the coming months. Javier R. Goicoechea talked about the velocity-resolved [CII] emission and [CII]/FIR mapping along Orion. The [CII] 158μm fine structure line is arising in gas irradiated by UV-photons from the Trapezium cluster and contributes significantly to the cooling of the cold neutral medium. These observations in combination with Far-Infrared photometric images of the dust emission and maps of the H41α hydrogen recombination and CO provide an unprecedented close view (0,16 light-years in resolution) of the Orion Cloud surrounding the Trapezium.

NANOCOSMOS at the recent ALMA / Herschel Archival Workshop (Garching, Germany)

alma_herschel_low_resFour NANOCOSMOS researchers gave their presentations at the ALMA/Herschel Archival Workshop held in Garching (Germany) at the ESO headquarters in April 15 -17, 2015. José Cernicharo (NANOCOSMOS Corresponding P.I.) talked about the synergies between the ALMA high resolution observations in the innermost zones of star-forming regions, AGB, post-AGBs stars and extragalactic objects and those of Herschel´s archive submillimeter and far-IR observations. Our postdoctoral researchers, Marcelino Agúndez, Guillermo Quintana-Lacaci and Belén Tercero talked about the following topics: Continue reading →

The project

idea

Cosmic dust is made in evolved stars. However, the processes involved in the formation and evolution of dust remain so far unknown. NANOCOSMOS will take advantage of the new observational capabilities (increased angular resolution) of the Atacama Large Millimeter/submillimeter Array (ALMA) to unveil the physical and chemical conditions in the dust formation zone of evolved stars. These observations in combination with novel top-level ultra-high vacuum experiments and astrophysical modelling will provide a cutting-edge view of cosmic dust.
