Baby Planets and Their Nurseries

We know that planets are born in the protoplanetary disks that surround stars when they are young. How these disks evolve into planetary systems is a fundamental question in Astronomy. Observations have revealed remarkable structures in disks that may indicate the presence of newly born planets. This talk will review these key observations and compare them to current theoretical predictions of planet formation. To conclude, possibilities for future progress in the field will be discussed.

Imaging Exoplanets: From Adaptive Optics to Starshade In Space

Direct imaging of exoplanets – “seeing” the planet as a separate point of light near a star – is extremely difficult, and several decades ago, scientists used to say that it would be impossible to image Earth-like exoplanets. Today this seems possible, using some combination of adaptive optics technology, coronagraphs, or starshades. Adaptive lets telescopes on the ground compensate for the Earth’s atmosphere. Coronagraphs use ultraprecise masks inside telescopes to block the diffracted light from a bright star. Starshades combine a space telescope with a huge flower-shaped spacecraft that flies in formation to block the starlight before it even reaches the telescope.. So what are we waiting for? What are the technological difficulties that make the development of exoplanet-hunting space telescopes so challenging? The future NASA Wide-Field Infrared Survey telescope could test out some of these technologies by studying Jupiter-like planets, and the proposed Habitable Planets Explorer (HabEX) mission could fully integrate them in a search for earthlike planets around dozens of nearby stars.
We invited two experts, astronomers and engineers, to discuss the progress in developing this technology and its future :
• Jeremy Kasdin, Professor at USF and Princeton University, is the leader of the coronagraph science (the Adjutant Scientist) for NASA’s WFIRST mission and has worked extensively on developing the technology for starshades.
• Bruce Macintosh, Professor at Stanford University, lead an exoplanet Science Investigation Team for the coronagraph instrument on the WFIRST mission and also has proposed mDOT, a microsatellite starshade demonstrator that would use a mini-starshade in low Earth orbit.
Both have been extensively involved in the development of coronagraph technology on Earth and for future space missions.

Going Deep, the NGC and IC Project

This presentation highlights how a group of amateur and professional astronomers (The NGC/IC Project) have re-examined the source material used to compile the original NGC in 1888 and have produced a corrected NGC that reflects the original visual discoveries.

The NGC and IC objects were discovered over 100 years ago, but 15% – 20% have identification problems, poor positions, misidentifications, duplicate entries, incorrect classifications, and confusion with single or multiple stars. The NGC/IC sleuths have recovered hundreds of mistaken identities, lost objects, and solved long-standing contradictions in professional and amateur databases.

The NGC/IC Project’s corrected database is now incorporated into several amateur software programs (SkySafari, StarryNight, TheSky, Voyager, Guide, SkyMap Pro, Cartes du Ciel, and more) as well as professional online databases such as as NASA-IPAC Extragalactic Database, SIMBAD and HyperLeda. In this talk he will discuss the history of the NGC and give several examples of their catalogue sleuthing.

Opening the 21 cm Window on Our Cosmic Dawn

21 cm cosmology promises to become a revolutionary new 3D probe of our early universe. With it, we can uncover the astrophysics of the “Cosmic Dawn” – the era of the first stars and galaxies – and test our standard model of cosmology with exquisite precision. Realizing the potential of 21 cm cosmology requires overcoming considerable challenges; the 21 cm signal is buried under foregrounds that are orders of magnitude brighter. We will need to carefully calibrate and analyze vast quantities of data from large radio interferometers. In this talk, I will present the Hydrogen Epoch of Reionization Array (HERA), a purpose-built 21 cm experiment under construction in South Africa. As the leader of the HERA analysis team, I will discuss the techniques we’ve developed and the progress we’ve made separating the 21 signal from astrophysical foregrounds. These will enable HERA to detect and characterize the signal throughout the Cosmic Dawn and cross-check the recent EDGES detection that points tantalizingly at new physics. Finally, I will lay out a vision for the next generation of telescopes that will directly map the majority of the luminous matter in the universe to fulfill the promise of 21 cm cosmology.

The extended Baryon Oscillation Spectroscopic Survey: clustering measurements, lessons, and prospects

In this talk, I will present the clustering analysis of the ELG (Emission Line Galaxy) sample from the eBOSS (extended Baryon Oscillation Spectroscopic Survey) program of the Sloan Digital Sky Survey and review the other clustering analyses of the eBOSS program, dedicated to Luminous Red Galaxies and Quasars. I will discuss theoretical, observational and analysis systematics, how they were estimated and mitigated, focusing on the improvements over the last release of the BOSS program in 2016. Specifically, I will start by presenting the extensive work of the eBOSS collaboration to test model predictions against N-body simulations. The different observational systematics of the eBOSS samples will be reviewed, as well as the adopted correction schemes and the new analysis techniques used to mitigate residual systematics. Different analysis assumptions and their impact on the clustering signal will be discussed. After a review of eBOSS legacy cosmological measurements, I will finish by drawing lessons and prospects for future galaxy surveys.

Did comet impacts jump-start life on Earth?

Recent observations confirming the presence of the protein-forming amino acid glycine in comets lend support to cometary impact as a possible source for delivering simple amino acids to early Earth. Little is known regarding the survivability or reactivity of glycine during impacts, especially considering that condensed phase chemistry at extreme conditions and can lead to the formation of new products through unusual synthetic routes. Quantum-based molecular dynamics (QMD) simulations are a useful atomistic modeling tool to predict chemistry that is difficult and expensive to isolate through laboratory experiments. With QMD, we explore how glycine reacts under the extreme temperatures, pressures, and shear states reached in shock impacts and other geological processes on early Earth and other planets and moons. Conditions typical of cometary impacts are found to prompt the rapid transformation of glycine into more complicated aromatic molecules. Shearing forces under more moderate compressive loads are predicted to drive formation of polypeptides and large oligomers. Our studies provide a “bottom-up” methodology and prospectus for predicting possible prebiotic chemistry under extreme conditions and help determine feasible chemical pathways towards chemicals needed for the origins of life.

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!

A Hybrid Deep Learning Approach to Cosmological Constraints From Galaxy Redshift Surveys

I will present a new technique for accurately determining sigma_8 and Omega_m from mock 3D galaxy surveys. The method is a hybrid technique; it merges deep machine learning with physics. The method is trained and tested on mock surveys that are built from the AbacusCosmos suite of N-body simulations, comprising 40 cosmological-volume simulations spanning a range of cosmological models. These simulations are populated with galaxies according to a flexible generalized halo occupation distribution (HODs) to capture a wide range of galaxy formation models. In addition to describing the advantages of this hybrid approach, I will also discuss best practices and lessons-learned for training a deep models more generally.

What Does a Black Hole Look Like: How We Got our First Picture

Black holes are one of the most remarkable predictions of Einstein’s theory of gravity: so much material is compressed into such a small volume that nothing, not even light, can escape. Black holes have also captured the public imagination, and are commonly featured in popular culture, from Star Trek to Hollywood movies. In Spring 2019, the world-wide Event Horizon Telescope released the first real (non-Hollywood!) picture of gas around a black hole and the “shadow” it makes as the gas swirls into the black hole. Dr. Quataert will describe how these observations were made and what they have taught us about black holes.

‘Passage to Mars’

Nobody gets to the red planet in Passage to Mars. Rather, the subjects of Jean-Christophe Jeauffre’s grandiose documentary are on a grueling trek through the Arctic, driving an experimental rover to Devon Island, a research site for potential Mars missions of the future. But that doesn’t keep team leader Pascal Lee from feeling like he’s an integral part of humanity’s giant interplanetary leap, and this attractive film plays along, hiring Zachary Quinto to read Lee’s journals with even more drama than he’d bring to a captain’s log if Spock subbed for Kirk in the next Star Trek adventure.

Lee leads a six-man team (two of whom are filmmakers) which hopes to drive the Okarian – a modified Humvee with tank-like treads – across the Northwest Passage to Devon Island before the winter sea ice melts. At Devon, the Okarian will be put through its paces in a vast, uninhabited desert terrain the Mars Institute uses to prep for long-term planetary exploration.

Jeauffre cuts lots of NASA-sourced Mars imagery into this icy story, drawing parallels between Arctic dangers and the sandstorms and isolation offered on that planet. Throughout, Quinto reads from Lee’s journals, which alternate between musing on the possibility that Mars missions will find life (or proof of earlier life) and chronicling more pressing concerns: the truck tread that blows apart en route, for instance; the failing alternator; and the risky decision to split the team up in search of crucial supplies.
