Kitty Ferguson: Stephen Hawking’s Biographer Hears the Music of the Spheres – Livestream

Join us virtually for a Monday Night Philosophy conversation with Kitty Ferguson about the life and scientific theories of Stephen Hawking, whom she first met in 1988. That encounter began her mid-life transition from being a professional singer, music teacher and Juilliard graduate to an explainer of difficult scientific concepts and Hawking’s biographer.
We will also discuss her nine other books, which she wrote in the clearest possible manner, translating from the “language” of mathematicians, scientists, and other experts into the language of the rest of us, without dumbing down the ideas. There is nothing more Pythagorean than that combination of clarity, theoretical science and music, and Ferguson’s childhood and family life, even more than her formal education, prepared her well for merging all three talents.
With George Hammond

Imaging extrasolar planets: GPI, GPI2, and miniature starshade – Livestream

In the landscape of exoplanet detection and characterization, direct imaging – spatially separating the planet from its parent star – remains the most challenging technique: all but the most massive and young planets are extremely faint, and the outer parts of planetary systems that imaging can access appear to be less populated than the inner reaches. Since the first set of discoveries in 2008, only a small number of planets have been imaged. Still, the spectral, orbital and statistical characterization of these systems has opened a window into a region inaccessible to other techniques.

I will give an overview of the field and summarize the results of the Gemini Planet Imager Exoplanet Survey (GPIES), the most comprehensive search for young wide-orbit giant planets to date. The extensive GPI survey helped us identify key factors for ground-based adaptive optics exoplanet imaging. Based on those, we are planning an upgrade: GPI 2.0. We will move the Gemini Planet Imager to the Gemini North telescope, upgrading the AO system and spectrograph to allow a new search for younger and lower-mass planets, precise characterization of target planets including atmospheric variability, and robust facilitiy operation for a range of non-exoplanet science applications.

Moving beyond the young giant planets will require either Extremely Large Telescopes, space-based adaptive optics coronagraphs, or space telescope + free-flying starshade combinations. I will review possible pathways for such instruments, including the WFIRST coronagraph technology demonstration. Starshades – where a carefully-apodized opaque spacecraft blocks the light of the star for a formation-flying telescope – are a particularly promising but untested approach. We have developed a concept for mDOT, a small-satellite starshade mission to validate the technology while carrying out a science program. It combines a 3-m starshade with a cubesat telescope in a sun-synchronous low earth orbit, and would be capable of imaging low-density asteroidal or cometary debris disks around nearby stars.

3D mapping of the dusty, magnetized ISM with starlight polarization – Livestream

The coming decade will mark a milestone in our understanding of interstellar magnetism: achieving a first reconstruction of the Galactic magnetic field in 3D. This will be crucial for progress in fields such as CMB cosmology and cosmic ray physics. Achieving this goal relies on the combination of (a) high-accuracy data that probe interstellar magnetism and (b) novel algorithms that enable the combination of different datasets. A first step towards this direction can be made through the use of starlight polarization in combination with stellar distances. I will discuss PASIPHAE, an upcoming optical polarization survey which aims at producing a tomographic map of the magnetic field orientation in the diffuse ISM. I will present results from a path-finding mini-survey and explore the wealth of information we gain by combining tomographic information with HI surveys in our Galaxy.

Interspecies Communication and the Search for Extraterrestrial Intelligence – Livestream

Dr. Laurance Doyle is an astrophysicist and principal investigator at SETI (Search for Extraterrestrial Intelligence) with expertise in diverse subjects including extrasolar planets, signal processing and communications theory. He has worked on image analysis from the Voyager mission and Halley’s Comet, developed statistical methodologies to search for extrasolar planets, and is applying those tools to analyze complex patterns and search for meaning in animal communications.

The World According to Physics

Jim Al-Khalili,Distinguished Chair in Physics, the University of Surrey; Author, The World According to Physics; Twitter @jimalkhalili
In Conversation with Adam Becker, Astrophysicist; Author, What is Real? The Unfinished Quest for the Meaning of Quantum Physics; Twitter@FreelanceAstro

Theoretical physicist Jim Al-Khalili offers a fascinating overview at what physics reveals about the modern world. Al-Khalili believes the knowledge discovered by physics both empowers and humbles us, and still, it continues to delve valiantly into the unknown.

He will introduce the fundamental concepts of space, time, energy and matter along with the three pillars of modern physics – quantum theory, relativity and thermodynamics – explaining how all three must come together if we are ever to fully understand reality.

Al-Khalili is the well-known BBC host of the long-running weekly radio program “The Life Scientific.”

Understanding stellar activity through stardust – Livestream

Stardust grains formed in the death throes of stars can be found today in meteorites. Some of these grains formed up to around three billion years prior to the solar system and are the oldest solids on Earth. Furthermore, these bona fide stellar remnants represent the sole samples that allow direct measurements of the processes underlying the formation of elements in stars..

In his talk Reto will discuss how, together with astronomical observations, measurements of the composition of ancient stardust can help us to understand stellar nucleosynthesis and galactic chemical evolution. By studying these processes we can begin to understand how the elements we are made of are formed in the first place.

Dark matter is the cosmic parent of all vast structures in the night sky, including our own Milky Way galaxy. Yet, we know so little about this mysterious stuff that constitutes over 80% of the material universe. This talk will illuminate our universe’s elusive dark matter, highlighting the ingenious methods that scientists use to search for it.

Seminar will be livestreamed here.
