ASTR 5835, Seminar in Planetary Science: IT CAME FROM OUTER SPACE: Interstellar Objects in the Solar SystemÌý
Instructor: Madigan & HayneÌý
Room: E126
4:00p-4:40p (T)

Description:The detection of three interstellar objects traversing the Solar System – 1I/'Oumuamua (2017), 2I/Borisov (2019), and 3I/ATLAS (2025) – provides the first direct observational constraints on material from other stellar systems. These detections enable empirical tests of theoretical predictions regarding planetesimal formation, ejection mechanisms, population statistics, and compositional diversity across planetary systems. In this graduate seminar, we will review the literature and latest research on these exciting objects and discuss the broader implications for planetary science.

ASTR 6000, Seminar in Astrophysics:ÌýMulti-messenger / Transient Universe
Instructor:ÌýRyuÌý
Room:ÌýE126
4:00p-4:50p (Th)

Description:Astronomers have long relied on light to unravel the mysteries of the universe. However, a new era has begun. We can explore various astrophysical phenomena using messengers of completely different natures, including electromagnetic radiation, gravitational waves, neutrinos, and cosmic rays. These "multi-messenger" probes offer unprecedented opportunities to address long-standing questions in astronomy. In this seminar, we will focus on short-lived astronomical phenomena, also known as transients, that occur within a human lifetime and represent promising or confirmed multi-messenger sources. These include, but are not limited to, compact object mergers, tidal disruption events, core-collapse supernovae, active galactic nuclei, and fast radio bursts. Rather than following traditional lecture format, the course will emphasize Ìýforefront research of multi-messenger astrophysics and transients through paper reading and discussions. Each week, groups of two to three students will present the fundamental background of a selected multi-messenger transient source and lead a discussion on a related research paper, using slides and / or the blackboard.Ìý
