Fall 2024
We investigate mass ejection from accretion disks formed during the collapse of rapidly-rotating Wolf-Rayet stars, also known as collapsars. The neutrino-cooled, black hole (BH) accretion disk that forms at the center of the star — and the ensuing outflows – provides the conditions for these...

Fall 2020
We investigate the production of fast ejecta from the contact interface in coalescing binary neutron stars. This ejecta expands rapidly enough (velocities > 0.6c) that the r-process freezes out, generating an ultraviolet precursor to the kilonova powered by the decay of free neutrons. Previous...

Croston, Judith H., Kraft, Ralph P., Hardcastle, Martin J., Birkinshaw, Mark, Worrall, Diana M., Nulsen, P. E. J., Penna, R. F., Sivakoff, Gregory Robert, Jordán, Andrés, Brassington, Nicola J., Evans, Daniel A., Forman, William R., Gilfanov, Marat, Goodger, Joanna L., Harris, Wayne E., Jones, Christine, Juett, Adrienne M., Murray, Stephen S., Raychaudhury, Somak, Sarazin, Craig L., Voss, Rasmus, Woodley, Kristin A.
We present new results on the shock around the south-west radio lobe of Centaurus A using data from the Chandra Very Large Programme observations (740 ks total observing time). The X-ray spectrum of the emission around the outer south-western edge of the lobe is well described by a single...
