Title:

Detecting the Ultra-Faint Galaxies Responsible for Cosmic Reionization with Gravitational Lensing and JWST Medium Bands

Agreement Number:

24JWGO3A04

Agreement Value:

$100,000.00

Agreement Date:

Mar 6, 2025 - Mar 1, 2027

Description:

Most of the hydrogen gas in the Universe is ionized, but prior to the formation of galaxies, the Universe was neutral. Once stars started forming, a significant phase change occurred in the universe, a process known as “Reionization”. This project will look for the faintest possible sources of Reionization, tiny dwarf galaxies. The project targets strong-lensing clusters which provide a factor of 3 - 50 boost in the brightness of background sources. This increase in sensitivity allows the detection of extraordinarily low-mass galaxies (the equivalent of large star-clusters) during the reionization epoch and quantify their role in this process.

Organization:

Canadian Space Agency

Expected Results:

The Research component of the program provides financial support to organizations to conduct space related research and development in priority areas. It will support targeted knowledge development and innovation to sustain and enhance the Canadian capacity to use space to address national needs and priorities in the future.
