Series: Astronomy Colloquium
Date: Wednesday 05-Apr-2023
Time: 16:05-17:00 (4:05-5:00 pm)
Location: ATL 2400
Speaker: Dr. Chris Reynolds (Cambridge/University of Maryland)
Title: The Science and Technology of the Advanced X-ray Imaging Satellite
The Advanced X-ray Imaging Satellite (AXIS) is a University of Maryland led response to NASA's call for Astrophysics Probe-class Explorer missions. Operating in the 0.3-12keV bandpass, AXIS will provide high-spatial resolution imaging (~1 arcsec) across a wide-field of view (24 arcmin diameter) with an order of magnitude more collecting area and sensitivity than our current capabilities (exemplified by the Chandra X-ray Observatory), while providing rapid response capabilities for transients sources. In this talk, I shall give an overview of the science of AXIS and the technology that makes it possible. AXIS will open new windows on the hot and dynamic Universe revealing the seeding mechanisms and early growth of supermassive black holes, the physics of feedback in galaxies, and the drivers behind explosive transients in the Universe. Launching in 2032, AXIS benefits from natural synergies with the Roman Space Telescope, the Rubin Observatory, ELTs, SKA, ALMA, ATHENA, and CTA. AXIS utilizes breakthroughs in the construction of lightweight X-ray optics from mono-crystalline silicon blocks, and developments in the fabrication of large format, low noise, high readout rate detectors allowing a robust and cost-effective design.
In-person colloquia are usually preceded by espresso and ice cream at 1:45 pm outside room PSC 1150 and are followed by an informal reception at 5:15 pm in that room. Anyone interested in talking with the speaker, or being added to the colloquium announcement email list, should contact the colloquium organizer Dr. Leslie Sage. Lunch will normally be reserved for the speaker to talk to graduate students. Anyone asking a question during a talk is asked to raise their hand and be acknowledged before speaking. Contact Dr. Leslie Sage for details.
