Hi Folks,

I am so sorry that I didn't send this invitation to you earlier. I hope a few of you can attend, but I understand that this talk announcement?was sent very late. Anyway, here is the information.

Talk title:?“Monsters in the dark: searching for the origins of the most massive galaxies in our universe”

Speaker:?Dr. John Weaver, graduate of the Williams School 2013.

Date:?Wednesday, April 16.

Refreshments:?4:15 - 4:30 p.m.????Talk Time:? 4:30p.m.

Talk location:?Fanning 111

Talk?Description:?Despite a century of observations, the origins of the most massive galaxies in the nearby universe remain elusive. Although much progress has been made, the details of their formation have been lost to time. Thankfully, telescopes are time machines, which means we can catch their progenitors in action in the distant, high-redshift universe. However, these galaxies are also extremely rare, forming in only the greatest collections of dark matter and cold gas. While this makes them ideal cosmological probes, observations capture only snapshots of different galaxies at different redshifts and cosmic epochs. Accurately piecing together this grand story therefore requires large statistical samples from the most sensitive infrared telescopes covering the widest areas. I will present our latest efforts to chart the formation and evolution of the most massive galaxies in our universe, taking us back to the first 500 million years after the Big Bang.

I hope you can join us this afternoon! Best,

Leslie
