The case for spectropolarimetry with SPEX on EJSM

, 2010
We present SPEX, our Spectropolarimeter for Planetary EXploration, and its application as science payload for EJSM. SPEX’ novel spectropolarimetry method allows to simultaneously measure radiance spectra (with a resolution of 2 nm) and polarization ...

Spectropolarimetry of SN 2023ixf Reveals Both Circumstellar Material and an Aspherical Helium Core

The Astrophysical Journal Letters
We present multi-epoch optical spectropolarimetric and imaging polarimetric observations of the nearby Type II supernova (SN) 2023ixf discovered in M101 at a distance of 6.85 Mpc.

Enigmatic Line Broadening during Solar Flares: Magnetic Field Broadening?

The Astrophysical Journal
The origin of the extreme broadening observed in chromospheric metal lines during solar and stellar flares—particularly Mg  ii h and k and Ca  ii H and K—remains poorly understood.

Snapshot channeled Stokes spectropolarimetry using optical rotators

Channeled spectropolarimetry has traditionally relied on thick retarders to encode polarization information onto spectra. Extensive research has been devoted to analyzing and mitigating the high sensitivity to azimuthal misalignment suffered by the ...
