[one_half] Prof. Nick Kaiser, Theoretical Astrophysics at the Institute for Astronomy, University of Hawaii Wide-field telescopes like those used in Pan-STARRS need to be collimated and aligned to very high precision in order to deliver sub-arcsecond image quality and low PSF anisotropy required by e.g. weak lensing. Errors in positioning of the large optical elements […]

[one_half] Juan Soler, Department of Astronomy & Astrophysics, U of T Spider is a balloon-borne polarimeter designed to probe the ultimate frontier of Hot Big Bang cosmology: Inflation. In order to achieve its goal, Spider needs unprecedented control of systematics without becoming too heavy to fly. During the discussion, PhD candidate Soler told the story

[one_half] Richard Chou, Department of Astronomy & Astrophysics, U of T Graduate student Chou has developed two designs for a wide integral field infrared spectrograph (WIFIS) that can provide an unprecedented large etendue and comparable spectral resolutions. Called WIFIS1 and WIFIS2, both designs work with an existing integral field unit called FISICA to provide 12\”
