Our group led on four JWST proposals and contributed to another two to study objects from the size of Jupiter to entire galaxies, from a few kiloparsecs to nearly 100 Megaparsecs. We were working right up to the deadline!
We have just published two new papers on the X-ray polarisation from accreting X-ray pulsars: 10.1093/mnras/staa3428 and 10.1093/mnras/staa3429. These are the first new models in nearly forty years!
About ten to twenty percent of white dwarfs are strongly magnetized, and the origin of the magnetic field is a mystery. We have taken a big step toward solving this mystery with the discovery that more than half of stars with initial masses between five and seven times that of the Sun form magnetic white dwarfs through single-star evolution. This is the first evidence that neither mergers or mass transfer are needed to build the strong fields on white dwarfs. Check out our ApJ paper 10.3847/2041-8213/abb5f7!
Denis has been chosen for a CITA National Fellowship to work at UBC from 2020 to 2022. Congratulations Denis!
Ilaria defended her thesis on QED and X-ray polarization from neutron stars and black holes. She’s off to Caltech as a Burke Fellow. Congratulations Ilaria!
It’s magnetic! It’s massive! It’s covered in helium! It may have a companion, and it was born from a single massive star! Check out the super white dwarf of Messier 47 in our ApJ paper 10.3847/1538-4357/ab2874!
