ANR Programme blanc: 2012-2017 (ANR-12-BS05-0016)

ANR TEAM: P.I. Lallement Rosine

Partenaires:

  • GEPI /Paris Observatory: Arenou F., Babusiaux C., Gomez A., Katz D., Haywood M., Lallement R., Leclerc N., Sartoretti P.
  • ACRI/ST: Vergely JL., Ferron S.
  • AIM/ IRFU: Grenier I., Casandjian J.M.
  • PHD students: Remy Q
  • Post-doc: Monreal-Ibero A.
  • New members of the GEPI team: ElYajouri M., Capitanio L.

Objective: produce tridimensional maps of the local InterStellar Matter (ISM) based on measurements of starlight absorption by dust (reddening effects) or gaseous species (absorption lines or bands)

Map description: see Lallement et al, A&A, 561, A91 (2014), Capitanio et al, (2017, arXiv:1706.07711). The current map is based on the inversion of reddening estimates towards 32,000 target stars.

Caution: in opaque regions the reddening maybe be underestimated, read paper before using maps.

To be implemented soon: planar distributions on demand, full 3D opacity distribution.
