CCAT / FYST: Tracing the Structure and Evolution of the Universe Using mm-Photometry and Spectroscopy. 

Speaker

Abigail Crites, Cornell University

Abstract

The Fred Young Submillimeter Telescope (FYST) is designed to measure the kinematic Sunyaev-Zel’dovich (kSZ) effect of galaxy clusters, aid in foreground removal for CMB surveys allowing us to probe inflation, and trace star-forming galaxies through line intensity mapping of their ionized carbon ( [CII] ) emission in the epoch of reionization. It is also designed to probe spectral lines in the ISM over a range of environments in the Milky Way, Magellanic Clouds, and other nearby galaxies. I will give and update on the status of FYST and the two cameras, CHAI and Prime-Cam, and discuss plans for early science after first light is achieved.

Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.
