Polarimetric analysis of STEREO observations of sungrazing Kreutz comet C/2010 E6 (STEREO)
Rok Nežič, Stefano Bagnulo, Geraint H. Jones +2
Twin STEREO spacecraft pre-perihelion photometric and polarimetric observations of the sungrazing Kreutz comet C/2010 E6 (STEREO) in March 2010 at heliocentric distances $3-28~R_{\…
Spectropolarimetry and photometry of the early afterglow of the gamma-ray burst GRB191221B
D. A. H. Buckley, S. Bagnulo, R. J. Britto +27
We report on results of spectropolarimetry of the afterglow of the long gamma-ray burst GRB 191221B, obtained with SALT/RSS and VLT/FORS2, as well as photometry from two telescopes…
The cloudbow of planet Earth observed in polarisation
Michael F. Sterzik, Stefano Bagnulo, Claudia Emde +1
Scattering processes in the atmospheres of planets cause characteristic features that can be particularly well observed in polarisation. For planet Earth, both molecular and scatte…
A search for strong magnetic fields in massive and very massive stars in the Magellanic Clouds
S. Bagnulo, G. A. Wade, Y. Naze +13
Despite their rarity, massive stars dominate the ecology of galaxies via their strong, radiatively-driven winds throughout their lives and as supernovae in their deaths. However, t…
