For his pioneering numerical simulations of collisionless shocks, particle acceleration by shocks and magnetic reconnection, and pulsar magnetospheres and their electromagnetic radiation. 

For his research into the physics of solar flares that significantly advances the study of magnetic reconnection and particle acceleration in solar flares.
 

For her leadership in the analysis of pulsar timing array data and her contributions to our understanding of the stochastic gravitational wave background.

For his pioneering work on radiative hydrodynamic modeling of solar and stellar flares as a means of understanding the response of the lower atmosphere to flare heating.

For leadership in the conception, design, delivery, science analysis, and continued support of the Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory.

For his experimental confirmation of the acceleration of auroral electrons by Alfven waves in the laboratory.

For leadership in the conception, design, delivery, science analysis, and continued support of the Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory.

For her remarkable contributions to our understanding of a wide variety of topics in extragalactic high energy astrophysics, for establishing the unification paradigm of active galactic nuclei, for her work on the origin of the extragalactic X-ray background, and for her tireless advocacy and support of women and underrepresented groups in science.

For developing numerical methods and tools to advance our theoretical understanding of cosmic ray and astroparticle physics, the evolution of black holes and active galactic nuclei, and dark matter physics.

For his book Northern Star: J.S. Plaskett (‎University of Toronto Press, 2018).

In recognition of his contributions to the understanding of the chemistry of ices in the interstellar medium and in the solar system.
