Remarkable gravitational-wave signal detected by the LIGO-Virgo-KAGRA (LVK) Collaboration

Today the LIGO-Virgo-KAGRA (LVK) Collaboration released information on one of the events detected during its current fourth observing run – a gravitational-wave signal from the collision of what is most likely a neutron star with a compact object that is 2.5 to 4.5 times the mass of our Sun. What makes this signal, called GW230529, intriguing is the mass of the heavier object. It falls within a…

White Dwarfs Get a Second Stellar Life Due to Buoyant Crystal Formation

By Milan P. Ilnyckyj, Canadian Institute for Theoretical Astrophysics
Research published in Nature by CITA National Fellow Simon Blouin grants new understanding of delayed white dwarfs.
Your astronomy textbook might describe white dwarfs as the cool and comparatively uninteresting remnants of dead stars. This perspective is challenged by the previously unexplained existence of delayed whit…

Two researchers from the Faculty of Arts & Science have been awarded prestigious Sloan Research Fellowships from the Alfred P. Sloan Foundation.

Maya Fishbach is an assistant professor with the Canadian Institute for Theoretical Astrophysics (CITA) whose gravitational wave research is helping revolutionize our understanding of stellar evolution, t…

CITA astrophysicists have been awarded major grants to study how magnetic energy from neutron stars is converted to radiation.

By Lyuba Encheva, Communications and Events, CITA

CITA faculty Bart Ripperda and postdoctoral fellow Gibwa Musoke have been awarded 250,000 computing hours at Oak Ridge Leadership Computing Facility (OLCF) for research on processes that power the extremely bright emissions that we see from neutron stars. The research project, which is a collaboration between CITA, University of Maryland,…
