SLAC Colloquium

Cosmic shadows and cosmic structures: the CMB as a Large-Scale Structure experiment – Livestream

Information about the late-time Universe is imprinted on the small scale CMB as photons travel to us from the surface of last scattering. Several processes are at play and small scale fluctuations are very rich and non-Gaussian in nature. I will review some of the most important effects and I will focus on the Sunyaev-Zel’dovich (SZ) effect and gravitational lensing. I will discuss how a combination of measurements can probe velocity fields at cosmological distances, serving as one of the most sensitive probes of initial conditions, and inform us on cluster energetics. If time allows, I will also discuss how to detect and characterize the properties of patchy reionization using the CMB as a backlight.

Stanford Applied Physics/Physics Colloquium

Frontiers in Optical and CMB Survey Cosmology – Livestream

Observations of the cosmic microwave background (CMB) and the galaxy-filled sky provide images of the universe at its various stages that are sensitive to its physics from the earliest moments to recent times. These observations are key to expanding our understanding to the physics of inflation, neutrinos, dark matter, and dark energy – some of the most mysterious terrains in physics today. We will present results from current CMB and optical surveys – the South Pole Telescope & BICEP/Keck Array and the optical Dark Energy Survey, respectively – whose unprecedented sensitivities enable us to stringently test the standard cosmological model and constrain new physics. We will discuss their current limitations due to calibration uncertainty and confounding astrophysical effects. To conclude, we will look forward to the bright future of optical, CMB, and joint cosmological experiments that will be performed by the Vera C. Rubin Observatory’s Legacy Survey of Space and Time and the CMB-S4 experiment.

Thanksgiving on Mars: Exploration & Human Missions Beyond Earth Orbit – Livestream

Humankind has always dreamt of traveling to new places and exploring new frontiers. When the Pilgrims’ arrived in the New World on wooden sailing ships in the 1600’s, they celebrated the first Thanksgiving with Native Americans and began settling into life in their new home.

Over time, the exploration and settlement on of our continent continued – initially on foot or by covered wagons, later by Transcontinental Railroad, and more recently by airplanes and jets, each time going further and faster using new technology. Even today, some dream of using rockets to take us to the Moon or Mars, perhaps to establish yet another frontier settlement.

But before we can celebrate Thanksgiving on a new planet, we’ll need more than just rocket scientists, engineers and daredevils. Designing human missions to other planets involves taking a broad perspective. Join us for a far-out and forward-looking adventure beyond Earth. And maybe some of you can get involved in the effort ahead. it will take all kinds of experts and lots of teamwork in the coming decades.

30 million galaxies seen through 5000 eyes – measuring the expansion of the Universe – Livestream

We know that our Universe is expanding, but how fast? Is it getting faster or slowing down? And why? The Dark Energy Spectroscopic Instrument (DESI), a state-of-the-art instrument on the Mayall telescope in Arizona, is equipped with 5,000 robotic optical fibers to capture the lights from 5,000 galaxies at one time. It will observe 30 million galaxies over the next 5 years, producing the largest data set of galaxies with high-resolution measurements of their colors. Find out all about DESI and how we will make a 3D map of the structure of our Universe, understand its expansion and tackle some of the biggest mysteries in cosmology; dark matter and dark energy.

After Dark Online: Celestial – Winter Solstice – Livestream

Lighten up your outlook as we observe the end of the sun’s journey across the horizon. The winter solstice marks the longest night of the year and return of daylight as our star reverses its apparent course in the sky. Learn about the significance of the solstice and the mechanics that make it possible, and celebrate the light during this final After Dark Online of the year.

The movements and mechanics of the planets, moons, and stars create awesome effects for us observers on earth. Predictable yet coincidental, these cycles among the stars lead to gravitational bulges, lunar alignments, and a turnaround of apparent motion. Join us this month as we explore these effects as opportunities for wonder and harbingers of future change.

Phone Home: Waiting for Signs of Life in the Known Universe – Livestream

Jill Tarter has spent more than 40 years trying to answer the question, “Are we alone in the universe?” An astronomer and co-founder of the SETI Institute, she was the inspiration for Ellie Arroway, the alien-hunting protagonist made famous by Jodie Foster in the 1997 Robert Zemeckis film adaptation of Carl Sagan’s novel Contact. Join us for Jill’s unique perspective on the search for extraterrestrial life as humanity peers out into the stars to determine who or what might be out there in the universe. But that’s just one part of the inquiry. Because as eager as we might be to get our first look at alien life, ultimately that discovery might reveal as much about ourselves as anything else. Because once we know we are not alone, perhaps we might reflect on what binds us as fellow humans, potentially inspiring us to overcome our differences here on planet Earth.

SETI Institute

Life on Venus? Or much ado about nothing? – Livestream

For decades, we thought of Venus as a completely uninhabitable planet because of the hellish environment on its surface. Yet, several scientists have championed the idea that life could exist in the thick cloud decks that shroud the planet.

Several weeks ago, a team of astronomers reported the detection of phosphine on Venus. If this stinky, toxic, perhaps biogenic gas does exist on Venus as reported, we stand to learn something profound. If clever chemists succeed in identifying a nonbiological source that produces phosphine, we will learn about the limitations of using atmospheric biosignatures to infer life. If they fail, this discovery increases our already high motivation to go to Venus and study its atmosphere in situ with 21st-century instruments.

To discuss this amazing discovery and its consequences for the search for life beyond Earth, we invited two astronomers: Clara Sousa-Silva, co-author of the study about phosphine on Venus and David Grinspoon, astrobiologist and member of the SETI Institute’s Science Advisory Board, and is part of the Breakthrough Initiative and co-investigator on multiple proposed missions to search for primitive life in the clouds of Venus.

The speakers will discuss whether or not phosphine detected on the planet next door is a signature of alien biology and how we might one day send a space probe to find out.

Science on Tap: A New Tool to Map Entire Galaxies – Livestream

All the popular images of galaxies, while beautiful, do not provide the information that astronomers need to measure the galaxies’ inherent properties, like the dynamics and composition of their stars and gases. Using the latest technological advances, Dr. McGurk is building a new, custom-designed instrument for Carnegie Observatories’ Magellan Telescopes that will peer into the Universe with extreme detail – making it possible to efficiently make 3D maps of galaxies, nebulae, and more.

San Francisco Amateur Astronomers

12 Years of Cosmic Fireworks with the Fermi Gamma-ray Space Telescope – Livestream

A single gamma ray carries millions of times the energy of a single photon of visible light. This means that gamma rays are produced only in the most convulsive environments in the universe; pulsars spinning inside magnetic fields, stars in binary systems devouring their partners and black holes at the centers of galaxies swallowing gas clouds more massive than our sun. The Fermi Gamma-ray Space Telescope was launched on June 11, 2008, to measure these extreme astronomical events. In this lecture, SLAC scientist, Eric Charles will describe how we observe astronomical gamma-rays and why we must go to space to see them. Then he will discuss how 12 years of observations from the Fermi Telescope have changed our understanding of the most violent objects in the universe.

The radiation belts of Jupiter and their interplay with Io and Europa – Livestream

The radiation belts of Jupiter are populated by energetic charged particles (electrons, ions) trapped by the gigantic magnetic field of the planet. The distribution and fluxes of these particles are sculpted by their interaction with the inner magnetosphere environment, including the environments induced by the volcanic moon Io and the icy Europa: surfaces, exospheres, extended neutral torii, cold plasma and electromagnetic waves. Conversely, the radiation belts of Jupiter are important to understand the weathering of Europa’s surface and the possible preservation of biosignatures. This seminar will give an overview on recent advances regarding the interlink between the Jovian radiation belts and the Io-Europa system. To do so, simulations conducted with a global physics-based model of the radiation belts will be contrasted with in-situ particle measurements by Pioneer 10-11, Voyager 1, Galileo and Juno. Remaining secrets that can be unlocked by a mission dedicated to the radiation belts of Jupiter will be presented, as their relevance to space physics and planetary science.

How the Visions of Sci-Fi Led the Way to Space – Livestream

Long before a rocket carried the first person into space, people journeyed to the Moon, Mars, and other worlds on flights of fancy�”imaginative voyages of fictional storytelling. Beyond entertaining us, science fiction tales have sometimes foreshadowed real events of space exploration and may even serve to shape future voyages.

You Can Almost Touch the Stars – Livestream

Even if you wanted to touch a star, they’re all impossibly distant. Despite these great distances, astronomers have learned an enormous amount about stars. How? The most common method to study the stars is called spectroscopy, which is the science of analyzing the colorful rainbow spectrum produced by a prism-like device.

Until recently, spectroscopy was too expensive and too complicated for all but a handful of amateurs. Today, though, new tools make spectroscopy accessible to almost all of us. You no longer need a PhD, dark skies, long exposures, enormous aperture … or a big budget! With your current telescope and FITS camera (or a simple web cam or even a DSLR without a telescope) you can now easily study the stars yourself. Wouldn’t you like to detect the atmosphere on Neptune or the red shift of a quasar right from your own backyard?!

This talk, with lots of interesting examples, will show you what it’s all about and help you understand how spectroscopy is used in research. Even if you are an armchair astronomer, understanding this field will enhance your understanding of the things your read and the night sky. We’ll do a live Q&A after Tom’s 45-minute presentation.
