Abstract: The guided transmission of optical waves is essential for modern applications in communication, information processing, and energy systems. Traditionally, light guiding in structures like optical fibers has been predominantly achieved through total internal reflection. In periodic structures, a range of other physical mechanisms can also facilitate optical wave transport.
Abstract: The Emirates Mars Mission (EMM) began its science phase on May 23, 2021, and has been making major contributions to the exploration of Mars' atmosphere on a global scale. From its weather-satellite-like orbit with a period of 55 hours, the Hope Probe uses its infrared, visible, and ultraviolet remote sensing instruments to measure the characteristics of the atmosphere extending from the surface all the way to the edge of space.
Abstract: Galaxy centers are extremal environments that frequently host supermassive black holes and uniquely dense and massive star clusters. In my talk I will focus on our understanding of these objects and their formation through the lens of our nearest galaxy nucleus, the star cluster Omega Centauri.
Abstract: The past 20 years have seen significant advancements in the teaching and learning in college-level Astronomy, with a particular focus on the introductory general education course (hereafter Astro 101). In recent years collaborators with the Center for Astronomy Education (CAE) have undertaken a theoretical approach to develop a new generation of instructional strategies. Beyond advancements in the teaching of Astro 101, this work has bridged to the teaching of Astronomy Majors courses.

Perhaps "The quark model for an AMO audience'' would be a better title? Anyway, I will tell you a bit about the spectroscopy of strongly interacting particles, a bit about the quark model, a bit about how people calculate the masses of bound states of quarks and gluons, and a bit about some states that I think are particularly interesting.
Abstract: We are all physicists, and have at least some acquaintance with mathematics. And we all have a fear of nuclear war. There are currently nine nations with these dreadful weapons. Can you name them? This colloquium will criticize the current meaning of deterrence, and offer an alternative, with evidence.
Abstract: Underpinning planetary science is a deep history of observation and, more recently, robotic exploration within the Solar System, from which models of planetary processes have been constructed. Concurrently, thousands of planets have been discovered outside our Solar System that exhibit enormous diversity, and their large numbers provide a statistical opportunity to place our Solar System within the broader context of planetary structure, atmospheres, architectures, formation, and evolution.
