    Astronomy (2015) PhD in Astronomy (November 2019) Supervisors: Maarten Baes, Ilse De Looze + Médéric Boquien (Chile) Postdoc at STScI (Nov 2019 - …) Supervisor: Karl Gordon Who am I and where do I come from? Dust, dust, dust, dust, dust,… 5
  4. The average NIR Milky Way extinction curve can be represented

    by a power law Dust extinction is not uniform across the Milky Way, but depends on R(V) The telluric absorption complicates the features JWST to the rescue! extinction wavelength (µm) extinction wavelength (µm) extinction wavelength (µm) Decleir et al.
