Astronomy Colloquium for 2017-10-18

Series: Astronomy Colloquium
Date: Wednesday 18-Oct-2017
Time: 16:05-17:00 (4:05-5:00 pm)
Location: ATL 2400
Speaker: Dr. Tod Strohmayer (GSFC)
Title: A NICER View of Compact Stars

X-ray observations provide a window into nature's extreme physics laboratories, neutron stars and black holes, the collapsed remnants of exploded massive stars. Nowhere else in the universe is the gravity stronger or the matter denser. Among the unanswered fundamental physics questions that can be addressed by their study are the equation of state (EOS) and basic constituents of ultra-dense matter, and the nature of extreme gravity. I will provide an X-ray tour of these objects, highlighting how X-ray observations enable addressing such questions, and with a focus on the new capabilities provided by NASA's recently launched Neutron Star Interior Composition Explorer (NICER) mission.

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. Lunch will normally be reserved for the speaker to talk to graduate students.

Colloquium Organizer: Prof. L. Drake Deming
