In Search of Dark Dwarf Galaxies

CITA Director Norman Murray is part of a team led by Yashar Hezaveh that recently analyzed and published data that could help solve the mystery of dark matter, which comprises roughly a quarter of the mass-energy in our universe.

The cosmological theory of cold dark matter (CDM) predicts that dark matter, the “glue” that holds our universe together, is cold: its particles move around…

CITA Prof. Pfeiffer and Former Postdoc Van Waerbeke Win the Humboldt Foundation’s Bessel Award

The Alexander von Humboldt Foundation [www.humboldt-foundation.de] grants about 20 Friedrich Wilhelm Bessel Research Awards annually, funded by the Federal Ministry of Education and Research, to internationally renowned academics from abroad in recognition of their outstanding accomplishments in research to date and their exceptional promise for the future. Award winners are invited to to spend…

First Evidence for Binary Black Hole Mergers

The gravitational waves detected on September 14, 2015 at 09:50:45 UTC from the two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) is first observation of a binary black hole merger. The initial black holes are found to have individual masses of 29 and 36 solar masses and merged to form a single black hole with a mass of 62 solar masses. The merger occurred at a…

Gravitational Waves Detected

LIGO scientist David Reitze takes us on a 1.3 billion year journey that begins with the violent merger of two black holes in the distant universe. The event produced gravitational waves, tiny ripples in the fabric of space and time, which LIGO detected on September 14, 2015, as they passed Earth.

Daniel Tamayo is the recipient of the 2015 Jeffrey L. Bishop Fellowship

Daniel Tamayo was awarded the Bishop fellowship for his work in orbital dynamics, particularly his recent research elucidating how forming planetary systems evolve to create the diversity of orbital architectures we observe around other stars today.

In the last twenty years, researchers have discovered thousands of planets orbiting other stars. The results are surprising, with about half of…

Star Men at Bloor Hot Docs Cinema

A documentary sponsored by CITA, the Dunlap Institute, and the Department of Astronomy and Astrophysics will be playing at the Bloor Hot Doc Cinema in Toronto in the coming weeks.

Written and directed by Alison Rose, the film follows four prominent astronomers on a trip down memory lane during a road trip through southwestern United States. A Q&A session with the director…

Professor J. Richard Bond Receives an Honorary Degree from SMU

On January 23, 2016, CITA Professor J. Richard Bond was one of two exemplary individuals presented with an honorary degree from Saint Mary’s University. He was bestowed a Doctor of Science, Honoris Causa degree from SMU to recognize his outstanding contributions to the field of cosmology.
A glowing account of Prof. Bond’s many accomplishments was published on SMU’s news webpage. SMU’s president…

New Light Shed on the Fast Radio Burst Mystery

NRAO Fast Radio Burst Press Release Video from NRAO Outreach on Vimeo.

Kiyoshi Masui speaks to Nature Podcast about the team’s recent findings.

A team of astronomers, led by the former CITA graduate student Kiyoshi Masui, and including current CITA professor Ue-Li Pen, have uncovered the most detailed record of a Fast Radio Burst…

NASA’s Swift and NuSTAR: Black Hole Has Major Flare

CITA National Fellow Dan Wilkins of St. Mary’s University was recently the lead author of a paper that more deeply characterizes the behaviour of supermassive black holes. The results from the observations by NASA’s Explorer missions Swift and the Nuclear Spectroscopic Telescope Array (NuSTAR) could “help us understand how supermassive black holes power some of the brightest objects in t…

Sackler Lecture: The Fourth Paradigm – How Big Data is Changing Science

Sackler Speaker: Alexander Szalay (Johns Hopkins University)

Abstract: The talk will describe how science is changing as a result of the vast amounts of data we are collecting from gene sequencers to telescopes and supercomputers. This “Fourth Paradigm of Science”, predicted by Jim Gray, is moving at full speed, and is transforming one scientific area after…
