Two KIPAC Tea Talks

Direct Imaging of Habitable Exoplanets* (*In the Next Decade)

Direct detection and detailed characterization of habitable exoplanets is a key science goal of future observatories. Although space-based telescopes will characterize exo-Earths in the late 2030s, extreme adaptive optics (ExAO) on extremely large ground-based telescopes (ELTs) has the potential to enable such characterization in the next decade. However, if current state-of-the-art ExAO instruments are placed on ELTs, we would still be orders of magnitude less sensitive than what is needed to image a habitable exoplanet. With current telescopes we are also orders of magnitude away from imaging and characterizing the thermal emission from young exo-Jupiters and the reflected starlight from any exoplanets. Current ExAO instruments are unable to reach these deeper contrasts due to chromatic and temporal wavefront errors. I will first demonstrate the effect of these limitations using on-sky datasets taken with the Subaru Coronagraphic ExAO system. I will then illustrate a path forward: fast focal plane wavefront sensing of both quasi-static and atmospheric speckles. Our new method, called the Fast Atmospheric Self-coherent camera Technique (FAST), is designed to overcome these limitations. I will present the concept of FAST and show results from both numerical simulations and laboratory testing. These results illustrate that the improvement from FAST could enable direct imaging of gas giants in reflected light and young exo-Jupiters in thermal emission on current telescopes and, in the future, habitable exoplanets on ELTs.

Learning from small scales in weak lensing and CMB data

Weak lensing of photons by large scale structure is sensitive to both the growth of the (lensing) structures and the expansion history of the universe. The large number of modes available on small scales have the potential to constrain cosmological parameters beyond what is achievable in the linear regime, but extracting this information from weak lensing surveys is not straightforward. I will review how to do so emphasizing the use of non-Gaussian observables and discuss how deep convolutional neural networks offer a viable alternative. The amount of information is limited by our ability to model the matter density field on small scales, including baryonic effects. I will end by explaining how future high resolution CMB experiments can inform simulations by measuring the angular momentum of baryons in the circumgalactic medium.

Super-Human Operator: Controlling Accelerators with Machine Learning

Particle accelerators are used every day in a wide range of scientific, medical and industrial applications. But did you know that the task of operating these machines is far from mundane? For example, for every experiment at SLAC’s X-ray laser, the Linac Coherent Light Source, human operators regularly adjust several dozen variables to carefully shape the beam, bring it to the correct energy for that particular experiment and maintain stable operation. This is no small feat for a beam that has to travel about a mile and go through plenty of nonlinear “beam gymnastics” along the way! Accelerator researchers are starting to turn to machine learning to see if we can make it easier to create new types of challenging beam setups and to speed up routine tuning. In this public lecture, Auralee Edelen, will take you on a journey through accelerator tuning and discuss some of the ways accelerator researchers are starting to use machine learning to help out with this challenging task.

Seeing the Unseeable: Capturing an Image of a Black Hole

Black holes are cosmic objects that are so small and dense, that nothing, not even light can escape their gravitational pull. Until recently, no one had ever seen what a black hole actually looked like. The Event Horizon Telescope (EHT) is a global array of radio dishes, linked together by a network of atomic clocks, that form an Earth-sized virtual telescope that can resolve the nearest supermassive black holes. The EHT detects light that is emitted from gas that is close to the black hole event horizon, and this light travels unimpeded to telescopes on the Earth. Einstein’s theories predict that the EHT should see a ring of light and a dark region within that marks the point where light cannot escape. On April 10th, 2019, the EHT project reported success: we have imaged a black hole, and have seen the predicted ring of light that confirms General Relativity as the boundary of a black hole. This talk will cover how this was accomplished, details of the first results, as well as some future directions.

The Event Horizon Telescope: Imaging a Black Hole

The Event Horizon Telescope (EHT) is a Very Long Baseline Interferometry (VLBI) array operating at the shortest possible wavelengths, which can resolve the event horizons of the nearest supermassive black holes. Observing at mm radio wavelengths enables detection of photons that originate from deep within the gravitational potential well of the black hole, and travel unimpeded to telescopes on the Earth. The primary goal of the EHT is to resolve and image the predicted ring of emission formed by the photon orbit of a black hole and to eventually track dynamics of matter as it orbits close to the event horizon. A sustained program of improvements to VLBI instrumentation and the addition of new sites through an international collaborative effort led to Global observations in April 2017: the first campaign with the potential for horizon imaging. After 1.5 years of data reduction and analysis we report success: we have imaged a black hole. The resulting image is an irregular but clear bright ring, whose size and shape agree closely with the expected lensed photon orbit of a 6.5 billion solar mass black hole. This talk will cover the project and first results as well as some future directions.

Telescope Makers Workshop
Chabot Space and Science Center
10000 Skyline Boulevard
Oakland, CA 94619-2450

Chabot’s TMW is one of only a handful of regularly scheduled telescope making workshops in the U.S., and probably the world; it meets every Friday evening throughout the year, except Memorial Day weekend. It has been in operation since December of 1930, founded by Franklin B. Wright, and is currently run by Eastbay Astronomical Society member Rich Ozer, with help from other EAS members, Dave Barosso, Barry Leska, and others. The price of admission is FREE. All you have to do is show up, buy a mirror blank and a “tool” (typically around $100 – $200 depending on the size of the mirror) and start “pushin’ glass!” We supply you with instruction, the various grits you’ll need to first grind, and then polish and figure your mirror, and all the testing equipment needed. With a small bit of luck, you could wind up with a telescope that costs 1/3 or 1/4 the cost of a store-bought telescope, that is yet optically superior! Itdoes take time – depending on how much time you put in on it, and other factors, it could take a few months or several months. But, it’s a fun project, great for kids, and at the end you get a great telescope!

Near Earth Asteroids, Space Missions, and the Impact Hazard

The near-Earth asteroids (NEAs) are a population of objects on orbit around the Sun that cross or come near the orbit of Earth; remnants of material from the early solar system that never accreted into planets. NEAs are accessible targets for space missions, but also pose a hazard due to potential future impacts onto Earth. Dr. Busch will review the near-Earth population and efforts to address the asteroid impact hazard. He will also discuss past, current, and future missions to near-Earth asteroids, including missions by NASA, ESA, JAXA, the Chinese National Space Agency, and potentially other groups.

Title: Pluto’s atmosphere dynamics and volatile transport investigated with numerical climate models

Abstract: Pluto’s tenuous atmosphere is mainly nitrogen and is in solid-gas equilibrium with the surface nitrogen ice. Over the past three decades, different Earth-based observations hinted at an exotic and dynamical atmosphere as they revealed (1) a much warmer atmosphere (70-100 K) than the surface (40 K), with a strong inversion in the first 20 km above the surface, (2) a threefold increase of surface pressure since 1988, and (3) global-scale oscillations in the vertical density and temperature profiles. In 2015, the observations made by the New Horizons spacecraft revealed the presence of magnificent haze layers, possibly due to gravity waves arising from N2 sublimation and orographic forcings. Surface-atmosphere interactions were also suggested by observed surface features, such as wind streaks and linear dunes, further highlighting the dynamical activity of Pluto’s surface and atmosphere.
New Horizons also revealed a complex distribution of the main volatile ices (N2, CH4, and CO), including the thousand-kilometers nitrogen ice-sheet in Sputnik Planitia, a combination of N2, CO and CH4 deposits at mid-latitudes, massive methane-rich deposits forming the Bladed Terrain at low latitudes, a methane mantle at high latitudes, CH4 snow-capped mountains near the equator, etc.
To understand all these observations, I have developed and used a hierarchy of models able to simulate Pluto’s climate and volatile transport over multiple timescales: (1) A Global Climate Model to represent the evolution of the 3D atmospheric circulation, the transport of gases and surface ices (N2, CH4 and CO) over up to several tens of Earth years (2) a 2D volatile transport model able to simulate the N2, CH4 and CO cycles over several tens of thousands of years (tuned using the GCM) and 3) A long-term Pluto evolution model combining the volatile transport model simulations with the variations of Pluto’s orbit and obliquity to simulate the evolution of the volatile reservoirs over up to 50 million Earth years. Such tools are based on universal equations, with the minimum of ad-hoc hypothesis.
At the seminar, I will review our knowledge of Pluto’s dynamics and volatile transport, and I will put forward what we have learned and what remains difficult to understand and predict with these models.
