Abstract:

The biggest news story from the first year of the James Webb Space Telescope is the existence of many more high-redshift galaxies than previously expected. This has sometimes been taken to extreme levels by suggesting that our understanding of galaxy formation in the cold dark matter model is fundamentally broken. I will discuss some of these first year results and explain what they are really telling us. I will show several results from the CAnadian NIRISS Unbiased Cluster Survey, CANUCS, and discuss their impact on this area of research.
 

Bio:

I am a Senior Research Officer (Astronomer) working in the Canadian Astronomy Data Centre group. My research interests are primarily in cosmological evolution, particularly the growth of black holes and massive galaxies. I use data from radio to X-rays to identify and understand galaxies and quasars up to the highest redshifts known. I am involved in the development of future observatories the James Webb Space Telescope and the Square Kilometre Array.
