. Summary of the scientific topics, and the amount of Herschel guaranteed time devoted to each of them. The
third column lists the participation of Astromol members to each topics: CC=C.Ceccarelli, BL: B.Lefloch.
In this respect, Astromol is involved in the project “Unbiased Spectral Survey of the solar type protostar
IRAS16293-2422” (leaded by E. Caux, CESR Toulouse), for which about 300 hours of IRAM and JCMT time
have been allocated (and used). Also, Astromol is involved in the JCMT Legacy Program “Spectral Line Surveys
of Star Forming Regions” (leaded by G.Fuller, Manchester, UK) which has been allocated about 200 hours.
In addition, a key aspect in this preparation is the participation to the European Network “The Molecular
Universe”, described below (§4.4). Note that, Herschel HIFI and ALMA are very complementary instruments.
Much of what we are developing and learning for Herschel HIFI will also be useful in the exploitation of ALMA,
and our group will not make this opportunity to be spoiled. To support our statement, in the last year we have
been developing a tighter collaboration with people at IRAM, notably the collaboration with Roberto Neri on
the exploitation of the Plateu de Bure to observe organic molecules in young embedded protostars as well as in
disks (as evident from the list of publications of our group).
4.4 The European Network “The Molecular Universe”
The RTN FP6 European Network “Molecular Universe” has been funded for 2005-2008 with the following
ambitious objectives: “This highly interdisciplinary network combines European researchers from 9 countries and
21 laboratories in the areas of laboratory spectroscopy, laboratory astrochemistry, molecular quantum mechanical
studies, astronomical modellers, and experts on data bases and web interfaces. By training future researchers
and by integrating European research efforts in the field of molecular astrophysics, Europe will be well poised
to take advantage of the planned European ground-based (such as Bure extensions and ALMA) and space-based
missions (such as Herchel-HIFI).”
France is strongly represented in this network, thanks to the active PCMI community. And among the
French groups, Astromol is highly involved.
In Task 1, “Molecular Complexity in Space”, we are involved in the three topics and in 11 milestones.
Namely for Topic 1.1, “Water in the Universe”, we are involved in milestones 1.1.2 to 1.1.7:
• 9D-Surface + rotational cross sections of H2O + H2
• 6D-Surface + rotational cross section of H2O + H/He
• Ro-vibrational cross-sections H2O + H/He/H2
• Ro-vibrational cross sections of HDO + H/He/H2
• Experimental measurement of state-to-state cross-sections for H2O + H2 and probing theoretical predictions
• Radiative transfer and excitation of H2O emission in photon dominated regions
Then for Topic 1.2, “Carbon Chemistry”, we are involved in milestone 1.2.8:
• Ab-initio intra and inter molecular interactions for HC3N and dynamics
For Topic 1.3, “Deuterium chemistry”, we are involved in milestones 1.3.3, 1.3.4, 1.3.6, and 1.3.7:
