The IFISM Workshop
In this workshop, we aim at gathering observers, modelers and chemical-physicists and discuss how recent advances in observational capabilities, model development, and experimental and theoretical studies of the key microphysical processes can shed a new light on our knowledge of the ionization fraction in the interstellar medium.
The workshop will include 4 invited review talks (30-45 min), and most of the time will be dedicated to short contributed talks (10-15min) for which abstract submissions will open in September. The meeting will be limited to 40 participants. The accommodation and meals will be supported by PCMI and the local sponsors.
The goal of this workshop is to attempt to answer the following questions:
How well can we measure the ionization fraction across all phases of interstellar clouds, form diffuse envelopes to dense cores? What are the reliability and the limitations of the observable tracers used to estimate the ionization fraction?
How well do the models explain the observed ionization fractions? What indirect impacts of the ionization fraction (on the dynamics, the chemistry,...) predicted by themodels can be observationally tested?
What are the key microphysical processes governing the ionization balance and its impact on the interstellar medium ? Which ones are well characterized, experimentally or theoretically, and which ones need yet to be investigated?
The workshop will be divided into four sessions :
Session 1 : Observational studies of the ionization fraction Review talk by: Cecilia Ceccarelli (IPAG, Grenoble)
Session 2 : Experimental studies of relevant processes Review talk by: Andreas Wolf (MPIK, Heidelberg)
Session 3: Theoretical studies of relevant processes Review talk by: Jonathan Tennyson (University College London)
Session 4: The ionization fraction in astrochemical models Review talk by: Evelyne Roueff (LERMA, Observatoire de Paris)
