The Big Ideas in Cosmology: An online interactive curriculum for introductory college students

The past several decades have brought a revolution in our understanding of the universe, its origin, and its constituent parts. While this transformation in our understanding has captured the imagination of the public as well as scientists, it has not strongly impacted how introductory college astronomy courses are taught; many still emphasize discoveries of the ancient Greeks and the Renaissance while giving little attention to recent advances.

Disentangling the 3D Dynamics of Particle and Wave Populations in Earth's Magnetosphere

The Earth’s magnetosphere is filled with various charged particle populations spanning orders of magnitude in energy, from the very cold (~eV) dense plasmasphere up to the high energy (~MeV) electrons trapped in the Van Allen radiation belts. Here we examine the coupled nature of these populations and the role of wave-particle interactions in transferring energy and momentum among them. In particular, we focus on the highly dynamic radiation belts, which often exhibit dramatic variations in intensity and spatial extent.

The Gas Giants as Unique Laboratories for Fundamental Space Plasma Processes

Jupiter and Saturn’s internal magnetic fields carve out a cavity in the solar wind (and its embedded interplanetary magnetic field) to form two of the largest magnetospheres in our solar system. Their locations in the heliosphere are characterized by vastly different solar wind conditions than are available at Earth, thus affording, for example, the exploration of some of the highest Mach number shocks ever recorded in situ.

Multi-scale Dynamics in Geospace Revealed by Optical Measurements

Aurora, optical emissions in the upper polar atmosphere, reflects a variety of space phenomena, and offers an opportunity for remote sensing of the space environment. Processes associated with aurora are not only important for Space Physics but also impact the human society such as radio communication and satellite operation during large space weather events. Recent studies have shown that localized structures in the Geospace system have major impacts on mass, momentum and energy transport in the system.

Innovation in the Semiconductor Industry: Implications for Education and Diversity

Abstract: Dr. Laura Oliphant has been at the forefront of technology for over 25 years, first at Intel, as an Engineer and Corporate Venture Capitalist, and now, as a General Partner of a Venture Fund, Board Director and CEO of startups.  She will talk about her career trajectory, the challenges for technology innovation going forward, the implications for education, diversity, and what she wishes that she had known in starting out in her career.

 

Quantum Seminar Series

The CUbit Quantum Initiative is launching a new seminar series to highlight frontiers in Quantum information science and technology and to foster interdisciplinary communications and collaboration. The seminar series is sponsored by CUbit with generous support from The Caruso Foundation.

The Emergence of Galactic Structure

Using a combination of the Hubble Space Telescope, the Keck telescopes, and the ALMA millimeter interferometer, we have begun to piece together a picture of the emergence of galactic structure: how the Universe evolved from its uniform state shortly after the Big Bang to the rich diversity of galaxies today. In this talk, I will discuss some of the results that have come out of my work and the impact they have had on our understanding of the formation and evolution of galaxies.
