SLAC Special Seminar: Sensitivity in Numbers : Scaling Up Superconducting Sensing at the Cosmic Frontier – Livestream

Many Cosmic Frontier efforts must instrument large numbers of superconducting sensors to meet their science goals. Though superconducting sensors offer unparalleled sensitivity in many applications, historically it has been very difficult to instrument them in the large numbers (hundreds or more) required to exploit their full potential. Superconducting sensor readout techniques developed by Cosmic Microwave Background (CMB) experiments, which have focused on this problem for the past decade, offer a path forward. These efforts have culminated in the CMB-S4 project, which aims to instrument a global network of CMB receivers with over 500,000 superconducting sensors. The combined sensitivity of the CMB-S4 receivers will dramatically improve our understanding of fundamental physics, including probing for signatures of primordial gravitational waves produced by inflation in the very early Universe. I will discuss the superconducting sensor readout techniques, which I have helped to develop, that have made the CMB-S4 project possible, as well as next generation readout technologies we are developing at SLAC. These next generation technologies have the potential for broad applications beyond CMB detection, including X-ray, gamma-ray, axion, and neutrino detection, 21-cm astronomy, and sub-mm to THz spectroscopy.

Searching With NASA’s SOFIA – Livestream

Get to know SOFIA, the Stratospheric Observatory for Infrared Astronomy, which recently helped scientists find water on the Moon. SOFIA is a specially-modified Boeing 747SP aircraft that carries a very powerful 106-inch reflecting telescope.

Soaring above 40,000 feet allows astronomers to study the Universe in ways that are not possible from the ground. What have scientists discovered from SOFIA’s views beyond Earth’s atmosphere? Learn more about this unique telescope and its role in research from NASA’s Dr. Backman.

Wonderfest: The Most Famous Equation – Livestream

Around the world, people recognize that E=mc^2 oozes cosmic insight. But what does this “most famous equation” really say? What are energy and mass? And what makes the speed of light, c, so important? [Hint: mass, moving at speed c, doesn’t turn into energy!] Using little more than common experience and middle-school math, Einstein’s “special relativity” gem can come to life – with surprising insights into the nature of reality.

SLAC Special Seminar

Large area Weak Lensing and the LSST Camera – Livestream

Weak gravitational lensing of the light from distant galaxies is a powerful tool for mapping the total matter distribution of the Universe, although measurement of the effect faces many subtle and challenging issues. Detecting the coherent shape distortion of weak lensing requires high-quality imaging and precise measurements. Ongoing and forthcoming surveys collect weak lensing data for very large areas of the sky. The Subaru Hyper Suprime-Cam is one of the current leading imagers for deep, large-area surveys. I was active in the development of Hyper Suprime-Cam and completed its commissioning. Using the images taken during commissioning, I conducted several weak lensing projects. I developed techniques to reduce the systematic error in weak lensing mass maps and verified the resultant mass maps by correlating them with dense spectroscopic surveys. Weak lensing measurements together with dense spectroscopy form a foundation for continuing advances in precision cosmology to constrain the distribution of dark matter and the nature of dark energy. I will discuss my work on the Vera Rubin Observatory’s LSST Camera as a step toward obtaining high-quality weak lensing data over the entire southern sky.

UC Santa Cruz

The Geometry of the Ancient Lunar Magnetic Field – Livestream

Paleomagnetic studies of Apollo samples indicate that the Moon generated a core dynamo lasting for at least 2 billion years. However, the geometry of the lunar magnetic field is still largely unknown because the original orientation of nearly all Apollo samples are unconstrained. Determining the direction of the lunar magnetic field over time could elucidate the mechanism by which the lunar dynamo was powered, whether the magnetic field underwent reversals, and whether the Moon experienced true polar wander. I will present measurements of the lunar magnetic field at 3.7 Ga as recorded by Apollo 17 mare basalts 75035 and 75055. These samples formed as part of basalt flows that make up wall-rock within Camelot crater in the Taurus-Littrow valley. Using layering in the parent boulder for 75055, we inferred its original paleohorizontal orientation on the lunar surface at the time of magnetization. We find that 75035 and 75055 record mean paleointensities of 37.3 ± 5.4 µT and 43.6 ± 4.6 µT, respectively. Furthermore, 75055 records a paleoinclination of 34 ± 11°. This inclination is consistent with, but does not require, a selenocentric axial dipole. Additionally, although true polar wander is also not required by our data, polar wander inferred from independent studies is consistent with our reported paleoinclination.

East Bay Astronomical Society

How to build the world’s biggest telescopes – Livestream

Increasing our knowledge of how the universe works has always been enabled by technological development. From the invention of the telescope by Galileo, over 400 years ago, to the development of 8 to 10 meter class telescopes and the launch of the Hubble telescope at the end of the last century, fantastic new discoveries have been made by users of the latest and greatest telescopes. Progress continues to this day, with three major new telescopes under development world-wide. After a brief overview Brian will concentrate on the current development of the Giant Magellan Telescope, a 25m diameter telescope expected to see light later this decade on Las Campanas Peak in Chile. Here are some of the questions he will address: Who’s designing and building it? What is the process for carrying out such a big project? Who will get to use it and what questions will they answer with the telescope?

UC Santa Cruz

A fireside chat with two pioneers in science, Sandra M. Faber and Kathryn D. Sullivan – Livestream

We are thrilled to invite you to an inspiring conversation with two of our most prominent trailblazers in science, and who we are proud to say will be distinctly honored in our transformed Science & Engineering Library.

The conversation will explore their incredible careers and the influence UC Santa Cruz has had on their unparalleled success. Among many of their accomplishments, for instance, Sandra co-led the largest project in the history of the Hubble Space Telescope, an undertaking that extended our view of galaxy formation back nearly to the Big Bang, while Kathryn was part of the team that launched, rescued, repaired, and maintained the Hubble Space Telescope. The list of their accomplishments, recognitions, and awards is unmatched. What inspired them to pursue these exceptional careers? What is next for them? What are their hopes for our current students?

Speakers: Sandra Faber, UC Santa Cruz emerita; Kathryn Sullivan, Astronaut; Beth Shapiro, UC Santa Cruz, Moderator
