Title: Mapping Sub-stellar Companions in Time and Space Abstract: Companion brown dwarfs and exoplanets are complex objects whose time and spatial variability are now being mapped with high-fidelity infrared observations from JWST. I will begin by presenting our analysis of JWST NIRSpec/IFU PRISM observations of the 2M1207 system that represent the first spectroscopic time monitoring … Continue reading "CRA SEMINAR – Dr. Arthur Daniel Adams [Dr. Gongjie Li]"

Title: Coronal Heating and Feedback from Luminous Accretion Flows: Challenges and Insights from Local and Global Simulations Abstract Radiatively efficient accretion represents a frontier problem for computational astrophysics. Through leveraging … Continue reading "CRA SEMINAR Dr. Christopher Bambic [Prof. John Wise]"

Title: Quasi-periodic Eruptions Abstract: Quasi-Periodic Eruptions (QPEs) are a newly discovered type of recurring X-ray transient originating from supermassive black holes (SMBHs) in nearby, low-mass galaxy nuclei. They are thought to be the first observed counterparts to extreme mass-ratio inspirals (EMRIs), a long-anticipated gravitational wave source class detectable by future space-based interferometers (e.g. LISA). About a dozen … Continue reading "CRA Special Seminar Joheen Chakraborty (Host Dr. Matthew Liska)"
