WEBINAR SERIES ON PREPARING JWST PROPOSALS

The James Webb Space Telescope (JWST) will re-issue its first “General Observer” (GO) call for proposals, in early 2020. It’s time for you to think about writing a JWST proposal. The proposal deadline will be May 1 2020.

We plan to give webinars as well as visit institutions across Canada in the winter of 2020 to help canadian astronomers prepare JWST time proposals. More details will be announced here soon.

In 2017/2018 the NIRISS Instrument Team gave a series of webinar to help the canadian community prepare time proposals. Our series of webinars is available on Youtube. We invited Canadian astronomers (students, postdocs and professors) to attend a series of webinars to help then prepare a JWST proposal. We taught you via demos how to use the available tools and documentation. A series of 8 webinars were given, on Wednesdays 4pm eastern time, between November 15 2017 and February 7 2018. The webinars lasted 1 hour each. They were recorded and posted online here and also on Youtube, here

The first two webinars are introductory presentations on JWST’s capabilities and its main proposal tools. Webinars 3 to 8 are meant to provide detailed demos of specific observing modes (imaging, multi-object spectroscopy, etc) based on a notional science case.

The webinars were presented by Rene Doyon (UdeM), Chris Willott (NRC-HAA), Julien Rameau (UdeM) and Loic Albert (UdeM). Any question with this series of webinars or with JWST can be addressed to jwsthelp@astro.umontreal.ca .

Webinar 3
December 6 2017, 4pm (EST)Demo for using the Imaging modes of NIRCam and MIRI

-Infrared detector readout, recap
-FOV and dithering patterns with NIRCam and MIRI
-Demo of the ETC
-Demo of the APT
The slides are here: PDF slides

The video recording is here:live video

We also produced a short video addressing the error encountered in the APT towards the end of the live demo that we did not have time to cover:addendum (use VLC)

The APT file is here: zipped APT file

To obtain the ETC workbook, please send an email to jwsthelp at astro dot umontreal dot ca and we will gladly share the ETC workbook produced during the live demo as well as a revised version that properly handles the NIRCam shortwave calculations.
Webinar 4
December 20 2017, 4pm (EST)Demo for using the Single Object Spectroscopy in long-slit (NIRSpec, MIRI) and slit-less (NIRCam, NIRISS) modes
