Astronomy Colloquium Zoom Talk
The Nancy Grace Roman Space Telescope and its H4RG-10 Detectors
Date: Thursday, December 2nd
Time: 3:30 pm - 5:00 pm
Place: This will be a Zoom Talk. Information to Follow soon.
Speaker: Gregory Mosby, NASA
Abstract: We have learned that our universe seems to be composed of significant amounts of invisible matter called dark matter and an unexpected dark energy driving the universe’s accelerating expansion. In the last few decades, we have also uncovered large populations of new worlds called exoplanets orbiting the stars of our Galaxy. These discoveries represent just a sample of the mysteries to investigate in our efforts to understand the universe. And to understand the universe, we must understand all its components. The Nancy Grace Roman Space Telescope will support this effort. The Roman Space Telescope with its Wide Field Instrument and the Coronagraph Instrument will help us study dark matter, dark energy, exoplanets, and more at infrared wavelengths. At the heart of the Roman Space Telescope are 18 newly designed infrared detectors the H4RG-10s. These detectors represent the state of the art in space-based detector technology. We will review the development and the performance of the flight lot detectors for the Roman Space Telescope, and we’ll cover the latest news from the project. The Roman Space Telescope will be an asset in the next decade, providing unprecedented wide and sensitive infrared surveys of the sky. These surveys by Roman will be key in helping us answer the open questions about the universe. This is a virtual talk. Please see the link below:
