2016 Yerkes Summer Institute: Spy vs. Spy
August 16, 2016
The 2016 Yerkes Summer Institute (YSI) was filled with secrecy, deception, and espionage. At YSI, high school students in the Space Explorers program played the role of 20th-Century spies to handle secret information: revealing, concealing and distorting information. Through three day-long lab activities, the students explored connections between spying and science. In the "Secret Photos" lab, they studied angular size, resolution, and the film-development process in order to effectively gather information on "enemy operatives" using 35 mm cameras. In the "Radio Beams" lab, students designed, built, and tested a system to transmit audio via an amplitude-modulated (AM) laser, which allowed them to secretly communicate across long distances. Lastly, techniques to securely communicate were examined in the "Codes and Ciphers" lab, which also served as an introduction to modern cryptography. After cycling through these three day labs, the students broke into three new groups and took one of the labs a step further: one group doctored photographs to spread false information, another built AM radio transmitters and receivers, and the last created treasure hunts using codes and ciphers for the clues. Nighttime activities included: observations with the Yerkes telescopes, astrophotography, explorations of the constellations which focused on what current research can tell us about them (e.g. most know exoplanets were found by Kepler in the constellation Cygnus); and bad weather activities that included examinations of the veracity of viral internet photos, and stories of famous spies. The week's spy-themed activities not only introduced the students to the importance of privacy in the digital age, but also to the concepts and skills that are integral to any modern STEM career.

Congratulations to Dr. Sean Johnson!
July 18, 2016
"Studies of the relationship between galaxies and the inter/circum-galactic medium".
"Sean's thesis work casts new light on the intricate physical processes that drive the baryon cycles between star-forming regions and the intergalactic space. He led an ambitious survey of the galactic environments around chemically-enriched gas revealed in strong absorption against a background source. Sean's thesis sample represents the first of its kind in terms of both the scale and depth of galaxy survey data in quasar fields. It provides a pathfinder for future large-scale studies that will combine wide-field galaxy surveys with absorption spectroscopy to advance our understanding of chemical enrichment in low-density regions away from galaxies."
- Hsiao-Wen Chen, PhD advisor
Sean will be starting as a Carnegie-Princeton/Hubble fellow at Princeton in the fall.

Congratulations to Dr. Asher Berlin!
July 8, 2016
"Phenomenology of Particle Dark Matter".
"Asher's work has covered a broad range of topics related to dark matter and efforts to reveal its particle nature. He has worked on theory calculations relevant to underground and space-based dark matter searches and to searches for dark matter at the Large Hadron Collider. More recently, he has worked on non-standard ways in which dark matter may be have created in the early universe."

Asher has received a Post Doctoral Fellow position at SLAC.

Congratulations to Dr. Jonathan Richardson!

"Experimental Constraints on the Exotic Shearing of Space-Time".
"Jon's thesis represents an important milestone. He's done much of the critical work to make the Holometer experiment a reality. It's the most sensitive instrument ever built to study tiny random jitters of space. In his thesis, he shows that the scale of random shear jitter is more than an order of magnitude less than the Planck length, which was the theoretical expectation. The experiment essentially rules out this effect. He's working with our team now to reconfigure the machine to study the other possibility, a jitter of rotational motion, at similar sensitivity. There is some hope that this effect in the laboratory may connect with the cosmic dark energy problem."

Congratulations to Dr. Laura Kreidberg!
May 24, 2016
"Snapshots of Faraway Places: Intensive Atmosphere Characterization of Extrasolar Planets."
"Laura conducted the most ambitious observational programs ever on the topic of exoplanet atmospheres for her dissertation. She used large investments of Hubble and Spitzer Space Telescope time to measure exoplanet atmospheric compositions, thermal structures, energy budgets, and dynamics to understand planetary origins and physics. The papers resulting from her work are the new benchmarks in the field, and provide a foundation for studying the atmospheres of potentially habitable planets with future facilities."
- Jacob L. Bean, Ph.D. advisor
Starting this summer Laura will be a Junior Fellow of the Society of Fellows at Harvard University and a Fellow of the Institute for Theory and Computation at the Harvard-Smithsonian Center for Astrophysics.

Congratulations to Dr. Alexander (Sasha) Kaurov!
March 29, 2016
"Challenges in theoretical modeling of cosmic reionization."
"Dr. Alexander Kaurov's work on studying cosmic reionization - the process of ionization of the bulk of cosmic gas by ultraviolet radiation from the first stars and quasars - was instrumental in combining diverse theoretical concepts into a single, unified paradigm that connects directly with modern state-of-the-art numerical simulations. This breakthrough will have numerous practical applications for the analysis and interpretation of the forthcoming observational data from the future James Webb Space Telescope, Giant Magellan Telescope, and radio observations of the epoch when the first galaxies lit up."

Erik Shirokoff has received a NSF CAREER award
December 22, 2015
"Developing Antenna-Coupled Kinetic Inductance Detectors to Enable Next Generation CMB Experiments". The team will design, build and demonstrate arrays of Kinetic Inductance Detectors (KIDs). A KID contains a very cold, resistance-free device. That device changes its properties when it "sees" the Cosmic Microwave Background (CMB), the faint signal from the young Universe. Vast arrays of KIDs are needed for the next generation of CMB experiments. The team will also provide laboratory experience for undergraduates from underrepresented minorities and for high school students in the Chicago area.
The CAREER award is presented to junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.
