Christine Joblin in a Nanocosmos illustrated talk

Last Saturday, the 2nd edition of the “Illustrated talks” organized by ERCcOMICS took place at Jussieu Campus in Paris with the artist Lorenzo Palloni and the researcher Christine Joblin (one of our Principal Investigators) in the “Fête de la Science 2017” (Science Party). It was an amazing opportunity to share the astronomy and astrophysics behind the Nancosmos project, that has already a comic inspired in its science. This “Fête de la Science” is a celebration of science and technology and thousands of individuals get involved, providing general public the opportunity to discover the wonders of science. “Illustrated talks” are talks where the artist illustrates the scientist live while talking about the project. Congratulations for this outreach initiative!

Watch the full illustrated talk (in french) by Christine Joblin (research director at CNRS Toulouse) & comics artist Lorenzo Palloni at the Fête de la Science in PARIS, Campus de Jussieu, on the 14th of October 2017.

Here, some pictures from the 2nd edition of the illustrated talks with the artist Lorenzo Palloni and the researchers Christine Joblin (ERC Nanocosmos).

“Estrella” (Star in Spanish) is the name of the comic inspired by Nanocosmos.

‘Estrella’, a comic inspired by Nanocosmos

homepage-banner-estrella-1The first chapter of ‘Estrella’ is out!

‘Estrella’ is a comic developed by an ERC proyect called ERCcOMIC and inspired by Nanocosmos. As the comic team believes in the power of visual storytelling, they illustrate each in a concrete, memorable and engaging way, drawing inspiration from science through stories and images.

The story of ‘Estrella’, by the artist Lorenzo Palloni, is set in 2106, and mankind is radically evolving. The NANOCOSMOS project has changed the path of astrochemistry and astrophysics, and now is the time for an elderly Estrella Leroux to pass the torch to three young scientists. Yet the story of an impossible journey of a young Estrella as a child inside the “Stardust” (a groundbreaking machine that reproduces the processes of a dying star) calls everything into question. The three budding stargazers will discover that their destiny is bound up with the mysterious Estrella’s, on the border between a surprising past and a never-so-uncertain future!

Don’t miss the story of Estrella and enjoy!

AROMA Setup First Results

The AROMA Setup

In the framework of the Nanocosmos ERC synergy project, a new analytical experimental setup called AROMA (Astrochemistry Research of Organics with Molecular Analyzer) was developed. The main purpose of this setup is to study and identify, with micro-scale resolution, the molecular content of cosmic dust analogues, including the stardust analogues that will be produced in the Nanocosmos Stardust machine in Madrid. AROMA combines laser desorption/ionization (LDI) techniques with a linear ion trap coupled to an orthogonal time of flight mass spectrometer (LQIT-oTOF). A first paper “Identification of PAH Isomeric Structure in Cosmic Dust Analogues: the AROMA setup” has just been published in The Astrophysical Journal. This is the first time that two-step LDI is coupled to a linear ion trap with MS/MS capabilities. In MS/MS experiments ions are first stored in a trap and then are fragmented under the action of photon or collision activation. The resulting fragments are then detected by mass spectrometry providing information on the molecular structure of the parent species.

The article presents the performances of AROMA with its ability to detect with very high sensitivity aromatic species in complex materials of astrophysical interest and characterize their structures. A two-step LDI technique was used, in which desorption and ionization are achieved using two different lasers which are separated in time and space. The tests performed with pure polycyclic aromatic hydrocarbon (PAH) samples have shown a limit of detection of 100 femto-grams, which corresponds to 2×108 molecules in the case of coronene (C24H12). We detected a mixture of PAH small and medium-sized PAHs in the Murchison meteorite that contains a complex mixture of extraterrestrial organic compounds. In addition, collision induced dissociation experiments were performed on selected species detected in Murchison, which led to the first firm identification of pyrene (C16H10) and its methylated derivatives in this sample.

AROMA setup, being highly sensitive, selective, spatially resolved, and owing the MS/MS capabilities enables unique chemical characterization of aromatic species in cosmic dust analogues and extraterrestrial samples. Changing the ionization source will enlarge the scope of investigated chemical species. In the future, it will be used to analyze samples from the Stardust machine, other laboratory analogues and cosmic materials such as meteorites, and interplanetary dust particles. Currently, we are developing an imaging source that will allow us to analyze samples using LDI with micrometer spatial resolution.
