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,…

McMaster And CITA astronomers use James Webb Space Telescope to probe cosmic history

Recent deep imaging data from the James Webb Space Telescope (JWST) shows a spectacular panoramic view of the Pandora Cluster, a remote, giant cluster of galaxies located 3.5 billion years ago. Marta Reina-Campos, who did this work while a CITA National Fellow based at McMaster, and William Harris, a McMaster emeritus professor, combined forces to analyse the exceptionally deep space images…

CITA Professor J. Richard Bond receives three prestigious honours from the international physics community

 In October, 2023 CITA’s Professor J. Richard Bond received two prestigious honours from the Canadian and American physics communities.

The Canadian Association of Physicists has named Bond a CAP Fellow “in recognition of his broad, stellar research contributions in the field of cosmology and astrophysics”. The CAP Fellows Program recognizes CAP members who have made significant…

Prof Norman Murray sheds light on why the day is 24 hrs long

Read the full A&S News Article by Chris Sasaki here, excerpt below
A team of astrophysicists, including CITA Prof Norman Murray, has revealed how the slow and steady lengthening of Earth’s day caused by the tidal pull of the moon was halted for over a billion years.

They show that from approximately two billion years ago until 600 million years ago, an atmospheric tide driven by t…

CITA Welcomes Six Fellows to 2023 Cohort

CITA extends a warm welcome to our incoming Fellows and National Fellows. In September, we will be joined by four Fellows at our flagship at the University of Toronto and two national fellows at the University of Waterloo and the University of Manitoba. We are committed to providing post-doctoral training for early career researchers in the field of Theoretical Astrophysics and are excited about…

CITA Faculty and Fellow Part of LVK’s Newest Observation Run

Today the LIGO-Virgo-KAGRA (LVK) Collaboration begins a new observing run with upgraded instruments, new and even more accurate signal models, and more advanced data analysis methods.

This observing run, known as O4, promises to take gravitational-wave astronomy to the next level. O4 will begin on May 24th and last 20 months, including up to two months of commissioning breaks. It will be t…
