The nucleus of our consortium consists of a well-balanced team of international experts in studies of star formation. NEMESIS members have been carefully matched to complement observational expertise at different parts of the electromagnetic spectrum but also to carry experience in modeling and interpretation of the observations. For an ambitious project about multi-wavelength data analysis like ours, it is essential to combine all our expertise and bring together particular scientific interests towards a larger, common goal.
Odysseas Dionatos (project coordinator) has long experience in studies of star and planet formation, focusing in the interplay between protostellar envelopes, accretion disks and protostellar jets and outflows. He has expertise in reduction and interpretation of data from ground-based and space-borne facilities (e.g. ALMA, Herschel, Spitzer) and maintains one of the largest, panchromatic databases of disk sources (DIOD). Beyond NEMESIS, he has been leading three successful projects funded by the Austrian Research Promotion Agency (FFG), in the framework of the Austrian Space Applications Programme, aiming to harness space mission science data relevant to star-formation. He has been a member of the JetSET (FP6) and DIANA (FP7) EU projects and has actively collaborated in a number of Austrian and international projects. Furthermore he is member for a number of candidate, scheduled and active missions, including SPICA, PLATO and ARIEL.
Marc Audard works on star and planet formation. He is an expert in observing young stars at different wavelengths, from X-rays to millimeter wavelengths, using satellites (e.g., Chandra, XMM-Newton,Spitzer, Herschel, Gaia) and ground-based observatories (e.g., VLT/VISIR, IRAM/PdBI, APEX, ATCA,VLA, ALMA). After his Ph.D. on the X-ray emission of magnetically active stars, he shifted his interests to star and planet formation, with an emphasis on the observational properties in young outbursting sources, on which he wrote with several colleagues a well-cited review for Protostars and Planets VI on episodic accretion in young stars. He collaborated with colleagues from the University of Vienna on a SNF-FWF project to study such outbursting sources, joining observational data with a thermochemical code, and numerical tools. He is furthermore still involved in several future missions; for example, he is strongly involved in the SPICA mission, a candidate mission for the M5 slot of ESA, both in the scientific and in the technical aspects (he leads the Instrument Control Center of the SPICA European instrument SAFARI, and manages the hardware participation for the SAFARI Grating Modules);he is also Science Co-I of the X-IFU X-ray calorimeter to fly onboard ATHENA, and is member of the X-CAT calibration group. He was a member of the Science Task Force of ASTRO-H/HITOMI before itsdemise and is now involved as Science Co-I for XRISM. As member of Gaia DPAC and CU7/DPCG, he is strongly involved in the definition of the products to be published in the Gaia archive, in the validation of the data products of the variability analysis. Since 2018, he is the Executive Secretary of the Euro-pean Astronomical Society, which gathers more than 3,500 members, mainly professional astronomers in Europe, and which organizes the EAS Annual Meetings (formerly EWASS), with 1000-1200 participants.
Gabor Marton has a decade long experience in the reduction of data collected by space instruments (AKARI, Planck, Herschel, WISE, Gaia) and in the analysis of the ISM, and pre– and protostellar objects. He is an expert of Herschel photometric data, was a member of the Herschel/PACS ICC. He was responsible for AAT of the HIPE, testing and benchmarking the HIPE map making algorithms. He was a leader of the Herschel/PACS Point Source Catalogue and an active participant for the Herschel/SPIREPoint Source Catalog, responsible for the photometric accuracy and noise estimation in both efforts. He is also an expert in statistical and machine learning methods, able to analyze the large scale distribution of celestial objects, also to develop and implement panchromatic automatic classification schemes. He created YSO catalogues for AKARI, WISE and Gaia DR2 (with combined citations of 72 by February,2020). As member of Gaia DPAC and CU5, he is involved with the Gaia Photometric Science Alerts, developing and implementing ML techniques for automated object classification (including eruptive YSO).He is also involved in the work of CU7 (variability analysis) focusing on the irregular variability of YSO candidates.
