Magnetic fields between the stars

The group measures the magnetic field of interstellar gas and dust and asks what it does: whether it guides gas into filaments and cores, and how it is organised across a whole galaxy.

The magnetic field of the Large Magellanic Cloud

Mapping the field of our nearest gas-rich galaxy from polarized dust and from the motions of its atomic hydrogen, and picking out its cold neutral phase.

Filaments and the field

Star-forming gas collects in long filaments. We measure how they line up with the magnetic field, and train neural networks to find them and read their orientation.

Where stars form

Magnetic fields, cores and gas flows inside individual molecular clouds: Orion, Monoceros OB1, infrared dark clouds and the centre of NGC 253.

Measuring polarized dust

The methods under everything else: how to estimate polarization fraction and angle without bias, and how the Planck satellite and the PILOT balloon measure them.

Scales of the measurements

Each bar runs from the beam to the size of the analysed map, at the distance adopted in the paper. Select one for the numbers.
