The College of Arts Sciences

Lectures & Colloquia

You are here


The Astronomy Department has regular, weekly colloquia during the fall and spring terms by distinguished scientists and scholars covering essentially all aspects of current astronomy, astrophysics, and space sciences - observations, theory, simulations, instrumentation, and history of astronomy. 

The colloquia are held every Thursday afternoon 4-5 pm in room 105 of the Space Sciences Building and are preceded at 3:30 pm by tea, coffee, and cookies. The public is welcome.

Astrophysics Lunch

Astrophysics Lunch is a series of informal talks on topics related to theoretical astrophysics, gravitational physics, and cosmology.  Speakers are free to present their own research or present papers that they find of particular interest.  The audience consists of faculty members, research staff, as well as graduate and undergraduate students, so talks should be at a level accessible to most. Astrophysics Lunch is open to talks from all members of the Cornell community, as well as to visiting scientists. We will reschedule a local speaker in order to accommodate visitors.

Astrophysics Lunch is held every Wednesday during the academic year at 12:15 PM in Space Sciences 622.

Bring your own lunch.

Date Topic Speaker
September 19, 2018 Radio Transient Sky Gregg Hallinan, Caltech


Galaxy Lunch

The Galaxy Lunch Series is held every Friday during the academic year, at 12:20pm, in Space Sciences room 622. In general, there will be an hour-long talk/discussion on topics related to galactic and extragalactic astronomy, and large-scale structure. The audience consists of faculty members, research staff, as well as graduate and undergraduate students, so talks should be at a level accessible to most. Galaxy Lunch is open to talks from all members of the Cornell Astronomy department, as well as to visiting scientists and speakers from different disciplines/departments.

Bring your own lunch.

The Thomas Gold Lecture Series

On the occasion of the retirement of the world famous astrophysicist, Tommy Gold, the University established the Thomas Gold Lectureship in Astronomy to bring outstanding scientists to Cornell for brief visits.

The Salpeter Lecture Series

The Salpeter Lecture Series was established in 1998 to honor Professor Edwin E. Salpeter, one of the most important astrophysicists of the 20th century. Under the auspices of the lectureship, distinguished astronomers and astrophysicists are invited to visit Cornell for one to two weeks.

Former Salpeter Lecturers:

The Yervant Terzian Lecture Series

On the occasion of Yervant Terzian's 70th birthday, the University established the Yervant Terzian Lectureship in Astronomy to bring outstanding scientists to Cornell for brief visits. The Lectureship was endowed by a generous gift from Friend of Astronomy Charles Mund, Jr.
