The Nanocosmos project was presented at The Physics of Evolved Stars (POE2015) conference by Nanocosmos astronomer Dr. Nick Cox on behalf of the three PIs. This international meeting, held from 8-12 June in Nice, France, was organised to honour Dr. Olivier Chesneau (Observatoire de Nice) who passed away in 2014. Presentations at the meeting covered the broad range of scientific interests of Olivier: from AGB stars, Planetary Nebulae, R CrB stars, Novae, Symbiotic systems, and many more. Many presentations at this meeting centred on understanding the formation and presence of dust and molecules in circumstellar environments of both low- and high-mass evolved stellar systems, topics of particular interest to Nanocosmos researchers.
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.

Four 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 →
