Samar Safi-Harb is a professor in the Department of Physics and Astronomy at the University of Manitoba and a Canada Research Chair in Supernova Remnant Astrophysics and Extreme Astrophysics. [1] [2] [3] She was the Vice President of the Canadian Astronomical Society from 2020 to 2021. [4]
Samar Safi-Harb grew up in Lebanon during the Lebanese civil war. [5] Despite loving physics in high school,Safi-Harb thought she would become a medical doctor and started a pre-medical physics undergraduate degree at the American University of Beirut. [5] [6] [7] After her undergraduate degree,she chose to follow her passion in physics and pursued graduate studies in physics at the University of Wisconsin-Madison,receiving her MSc in 1993 and her PhD in 1997. [5] [8]
Following her graduate studies,Safi-Harb completed a fellowship at NASA's Goddard Space Flight Center where she worked in the high energy astrophysics lab. [5] In 2000,she left NASA to start the University of Manitoba's graduate astrophysics program. [5] [6] [7]
Safi-Harb's research focuses on high energy studies of the remnants leftover by supernovae,including neutron stars and their nebulae. [1] [9] In 2021,Safi-Harb and her former graduate student Harsha Blumer published their results from their observations of the magnetar Swift J1818.0−1607,first detected by the NASA's Neil Gehrels Swift Observatory in 2020,using the Chandra X-Ray Observatory. [10] [11] [12]
A magnetar is a type of neutron star with an extremely powerful magnetic field (~109 to 1011 T,~1013 to 1015 G). The magnetic-field decay powers the emission of high-energy electromagnetic radiation,particularly X-rays and gamma rays.
Bryan Malcolm Gaensler is an Australian astronomer based at the University of California,Santa Cruz. He studies magnetars,supernova remnants,and magnetic fields. In 2014,he was appointed as Director of the Dunlap Institute for Astronomy &Astrophysics at the University of Toronto,after James R. Graham's departure. He was the co-chair of the Canadian 2020 Long Range Plan Committee with Pauline Barmby. In 2023,he was appointed as Dean of Physical and Biological Sciences at UC Santa Cruz.
The Canadian Institute for Theoretical Astrophysics (CITA) is a national research institute funded by the Natural Sciences and Engineering Research Council,located at the University of Toronto in Toronto,Ontario,Canada. CITA's mission is "to foster interaction within the Canadian theoretical Astrophysics community and to serve as an international center of excellence for theoretical studies in astrophysics." CITA was incorporated in 1984.
