A two-hour astronomy lecture forthcoming at the California Institute of Technology (Caltech) will examine how supercomputer simulations help scientists understand the complex formation of galaxies like the Milky Way.
The free public lecture on Friday, Dec. 6, from 8 to 10 p.m. at Caltech’s Cahill Center for Astronomy and Astrophysics, will feature Ph.D. candidate Sam Ponnada.
Ponnada’s presentation will focus on how computational astrophysicists use advanced technology to model the intricate interactions between dark matter, gas, dust, stars, magnetic fields, and black holes.
The event, part of Caltech’s monthly Stargazing Lecture Series, will begin with a lecture from 8 to 8:45 p.m., followed by panel discussion and guided stargazing until 9:45 p.m.
While the stargazing portion depends on weather conditions, the lecture and Q&A segments will proceed as planned, with remote viewing available through YouTube at youtube.com/live/tMItLLsdu28.
The presentation aims to demonstrate how ordered galactic structures, including spiral arms and disks, emerge from what Ponnada describes as “cosmic chaos” in these complex celestial systems.
Attendees may stay for any portion of the event.
No reservations are required for the series. Members of the public are welcome.
