JWST Community Lectures
Gabriel Brammer  (Space Telescope Science Institute)
I will review the wide-field slitless spectroscopic (WFSS) capabilities of the JWST instruments NIRISS and NIRCam. Using a grism element and no slits, JWST WFSS will probe parameter space intermediate between standard imaging and IFU and multi-objec ...

JWST Community Lectures
Anand Sivaramakrishnan (STScI) (STScI)
I will highlight the strengths of JWST NIRISS’ Aperture Masking Interferometry (AMI) mode, and present a few science cases to demonstrate its use. AMI imaging enables moderate contrast 3-5 micron imaging, at 70-400 mas separations, where JWST’s coro ...

JWST Community Lectures
Diane Karakla (STScI)
I will present an overview of the process for planning multi-object spectroscopy using the NIRSpec MSA, and will demonstrate the software tool to help plan MOS observations using a typical science case. The MSA Planning Tool (MPT) is currently availa ...

JWST Community Lectures
Swara Ravindranath  (Space Telescope Science Institute)
The JWST Exposure Time Calculator is an advanced pixel-based ETC which enables the user to model various aspects of the data acquisition and post-processing, and is paired with an interactive graphical user interface that facilitates exploration of p ...

JWST Community Lectures
John Stansberry  (STScI)
I will summarize how observers can plan JWST observations of moving targets (objects within the solar system). I'll address limitations on observing geometry, apparent rate of motion, and epoch, as well as brightness limits and sensitivity for the fo ...

JWST Community Lectures
Bill Blair  (STScI)
Proposers with HST experience are no doubt familiar with the Astronomers Proposal Tool (APT), which is really a GUI-interface into a suite of tools used to propose for and ultimately schedule observations on the telescope. Despite the numerous diff ...

JWST Community Lectures
Klaus Pontoppidan  (Space Telescope Science Institute)
STScI just released the flight version of the Exposure Time Calculator for the James Webb Space Telescope. The ETC is based on a code called Pandeia. It includes a Python engine, which models astronomical scenes in three dimensions and simulates two- ...

JWST Community Lectures
James Muzerolle  (Space Telescope Science Institute)
Multi-object spectroscopy (MOS) is a crucial capability for measuring the properties of statistically significant samples of stellar or galaxy populations. Such a capability has become more common on ground-based facilities via fiber-fed or slit mas ...

JWST Community Lectures
Jay Anderson (STScI)
It took longer than people expected to get good distortion solutions for Hubble, but JWST will need a high-precision solution from day 1. For this reason, in 2006, we constructed an astrometric standard field in the LMC (in the CVZ) in order to enab ...

JWST Community Lectures
Karl Gordon (STScI)
The JWST absolute flux calibration program is based on observing a set of stars to provide a unified, robust flux calibration across all JWST instruments. The set of calibration stars has been chosen to include the three categories: hot stars, A-typ ...

JWST Community Lectures
David Law  (Space Telescope Science Institute)
Integral-field unit (IFU) spectrographs are becoming common tools for major astronomical facilities, and have begun to open new scientific regimes to study through spatially resolved spectroscopy. JWST will include two such instruments (as part of M ...

JWST Community Lectures
Laurent Pueyo  (STScI)
JWST has a suite of coronagraphs designed to provide high contrast observations of astrophysical objects from 2 to 23 microns at unprecedented sensitivities. To plan observations, users will have decide how to read out the detector, how long exposure ...

JWST Community Lectures
Christine Chen (STScI)
JWST has a suite of instruments designed to provide high angular resolution images of the infrared sky at unprecedented sensitivities. To plan observations, users must specify the how the telescope is dithered, how the detector is read out, how long ...

George Rieke  (University of Arizona)
Mid-infrared astronomy from the ground is severely limited by huge thermal backgrounds. Sensitive measurements have depended on space missions, which have been limited in aperture and hence in angular resolution. For the first time, MIRI with JWST pr ...
