SLAC Colloquium

Dark Matter: A Cosmological Perspective – Livestream

While it is considered to be one of the most promising hints of new physics beyond the Standard Model, dark matter is as-yet known only through its gravitational influence on astronomical and cosmological observables. I will discuss our current best evidence for dark matter’s existence as well as the constraints that astrophysical probes can place on its properties, while highlighting some tantalizing anomalies that could indicate non-gravitational dark matter interactions. Future observations, along with synergies between astrophysical and experimental searches, have the potential to illuminate dark matter’s fundamental nature and its influence on the evolution of matter in the cosmos from the first stars and galaxies to today.

Speaker: Katie Mack, North Carolina State University

Ubiquitous Thoughts & SETI

Mars, Machine Learning, and the Search for Life beyond Earth – Livestream

Join us for this very special Ubiquity Ventures event open to the public. On Wednesday, March 31st, we will celebrate the recent news of NASA’s Perseverance Rover landing on Mars with a Ubiquity event focused on the search for life beyond Earth and how “software beyond the screen” is playing a role.
We will start with SETI Institute founder Jill Tarter who will speak about her lifelong search for life beyond Earth, the importance of this search, and the evolution of techniques used since her work in this area began over 40 years ago.
Then Ubiquity Extended Team member Hannah Kerner will talk about how “software beyond the screen” is accelerating the search via novelty-guided targeting using machine learning developed for the Mars Perseverance and Curiosity rovers. She will give an overview of how machine learning is currently being used on Mars to flag novel geology in data transmitted to the Terrestrial rover planning team, and, in the future, allow the rover to autonomously detect and acquire follow-up observations of significant targets. These machine learning methods apply deep neural networks and other algorithms to rapidly identify geology-related patterns in images that are novel compared to images previously taken by the rovers.

SLAC Colloquium

Polarized emission around the M87 supermassive black hole – Livestream

In 2017 April, the Event Horizon Telescope (EHT) observed the near-horizon region around the supermassive black hole at the core of the M87 galaxy. These 1.3 mm wavelength observations revealed a compact asymmetric ring-like source morphology. This structure originates from synchrotron emission produced by relativistic plasma located in the immediate vicinity of the black hole. Now we present the corresponding linear-polarimetric EHT images of the center of M87. We find that only a part of the ring is significantly polarized. The resolved fractional linear polarization has a maximum located in the southwest part of the ring, where it rises to the level of ∼15%. The polarization position angles are arranged in a nearly azimuthal pattern. We will discuss the polarimetric data reduction and analysis methodology. The polarimetric images carry information about the structure of the magnetic fields responsible for the synchrotron emission. We will discuss the theoretical implications of these observations.

The Discovery of Gravitational Waves – Livestream
A brief (pre)history of the Discovery of Gravitational Waves

Mario Kalomenopoulos

The detection of gravitational waves some years ago, opened a new window to the Universe, created a media fuss and gave a Nobel Prize for Physics! But what is the story behind this discovery? What about the discovery claims of the 60s? And where does Glasgow fit into this mystery? In this talk, we’ll try to answer these questions (and maybe some more) concerning the discovery of these mysterious waves.
