B-G’s Home Page

Welcome to the research web-site of B-G Andersson, a Swedish astronomer working at the SOFIA Science Center located at the NASA Ames Research Center, just outside of Mountain View, California.

At the ESO observatory on La Silla, Chile, in 2014

I’m currently the SOFIA Associate Director of Science Operations.
I have previously worked for the Far Ultraviolet Spectroscopic Explorer (FUSE) mission out of Johns Hopkins University and in various positions at the Jet Propulsion Laboratory.  A current résumé can be found here.

My research interests center on interstellar medium (ISM) physics and in particular the transition from molecular to atomic gas in interstellar clouds, and on the mechanisms responsible for aligning dust grains [with the magnetic fields] in the ISM.

I received my PhD (well, technically a “Fil. Dr.”) from the University of Gothenburg (Göteborgs Universitet), Sweden, working with Peter Wannier. My thesis was entitled “Over the Edge; On the astrophysics of interstellar cloud halos” and my faculty opponent at my defense was the Nobel Laureate Dr. Robert Wilson.

I’ve worked at the Jet Propulsion Laboratory, the Johns Hopkins University and the SOFIA Science Center, located at NASA Ames.

I’ve held visiting or part time (teaching or research) positions at Observatoire de Paris, Meudon, UCLA, USC, U Toledo and currently at UCSC.

The SOFIA Science Center staff  had two chapters in the Annual Reviews of Astronomy and Astrophysics in 2015.   One by myself, Alex Lazarian and John Vaillancourt and one by Adwin Boogert, Perry Gerakines and Dough Whittet.  Here’s a picture from the “Book Release Party” we threw at the SOFIA building

The AAS put me and Tommy Wiklind (CUA) on the banner for one of their e-mail today (Dec 2, 2016).   Two Swedes enticing Americans to attend the AAS (in Grapevine) – of which I am, indeed, a member in good standing order.

Then, at the AAS meeting 231 in D.C. (Jan 2018), I organized and chaired the SOFIA Town Hall.  (And, “The motion carried”)

Flew my 10th SOFIA mission on Feb 9/10, 2017, observing [C II] in IC 59 and IC 63 with upGREAT.

The French science agency CNRS recorded the SOFIA observing experience by our GI Olivier Berne.  Towards the end of the video yours truly discusses some of the advantages of SOFIA.


I ‘m still working on this site, so bear with me while I populate and (hopefully) enhance it.
