Accretion onto black holes is the source of some of the most energetic photons observed in the Universe. The innermost region of the black hole accretion disk radiates mostly in X-rays for both stellar and supermassive mass black holes. This project will capitalize Canada’s participation in ASTROSAT by using the unparalleled simultaneous broadband X-ray data to probe the debated inner accretion dynamics of black holes across the mass range. The investigation lines up with one of Canada’s Long Range Plan main science themes (“What are the extreme conditions of the Universe?”) and with the Canadian priorities in High-Energy Astrophysics.

The project will analyze data from the most recent Astrosat X-ray and ultraviolet observatory programs on M31 and Hercules X-1. M31 (Andromeda) is the nearest large neighboring galaxy to our own Milky Way galaxy. It presents astronomers with an ideal viewpoint of a galaxy, in contrast to our galaxy which is mostly obscured by dust. We will measure the hot stars in M31 to learn about the formation and structure of that galaxy. Hercules X-1 is a normal star in orbit with a neutron star that emits X-rays and ultraviolet light as it funnels matter from the normal star. The study will measure the matter flows from star to neutron star, and how the matter emits X-rays and ultraviolet light.

Following the JWST ERS and Cycle 2 GO Announcement of Opportunity published on July 6, 2023, the CSA is providing funding via a Grant Agreement to the university to conduct their research using the JWST data.

This project will study accretion onto the supermassive black hole at the Galactic Center, Sagittarius A*, using MIRI MRS IFU time-series spectral monitoring of Sgr A* and its surrounding region. Along with simultaneous Chandra observations, this data will be used to characterize the black hole’s MIR and X-ray emission in different flux density states, determine the nature of the emission, and constrain models of the accretion and radiation processes.

This project aims to use satellite measurements and targeted experiments to evaluate and improve the current understanding of chemical emissions from Canadian forest fires, crucial for enhancing modeling of smoke plumes and assessing their impacts on human health and the environment. By focusing on obtaining glyoxal and formaldehyde column densities and refining emission factors and branching ratios, the research seeks to advance forest fire smoke modeling, potentially mitigating the societal challenges posed by increasing prevalence of forest fires.

Contribution agreement with the University of Illinois to support the North American Technical Center of the Information System on Occupational Exposure network.

Operating costs: The project aims to offer Quebec SMEs a support service to implement their sustainable development action plan, in particular through the implementation of clean technologies and eco-responsible practices.
