Overview
Gregg Hallinan studies new and variable sources that appear in the radio sky. These include the electromagnetic counterparts of gravitational wave events, as well as stellar space weather and exoplanet magnetic fields. He has led the development of a new generation of radio telescopes, including the upcoming 1650-dish Deep Synoptic Array (DSA), which will be the world's most powerful radio telescope. The DSA will have the first radio camera that will create images in real time.

Ay 141 abc. Research Conference in Astronomy.
2 units (1-0-1); first, second, third terms, 2025-26.
Oral reports on current research in astronomy, providing students an opportunity for practice in the organization and presentation of technical material. A minimum of two presentations will be expected from each student each year. In addition, students are encouraged to participate in a public-level representation of the same material for posting to an outreach website. This course fulfills the option communication requirement and is required of all astronomy graduate students who have passed their qualifying exam. It is also recommended for astronomy seniors; non-seniors can attend but cannot take the course for credit. Graded pass/fail.

Ay 31. Writing in Astronomy.
3 units (1-0-2); second term, 2025-26.
This course is intended to provide practical experience in the types of writing expected of professional astronomers. Example styles include: research proposals, topical reviews, professional journal manuscripts, and articles for broader audiences such as popular level magazines like Astronomy or Sky and Telescope. Each student will adopt one of these formats in consultation with the course instructor and write an original piece. An outline and several drafts reviewed by both a faculty mentor familiar with the topic and the course instructor are required. This course is most suitable for juniors and seniors. Fulfills the Institute written scientific communications requirement.
