Anne Gambrel will receive her PhD from Princeton University. For her graduate degree, she helped build, launch, and analyze the data from the SPIDER balloon-borne CMB polarimeter, designed to measure large scale B-mode polarization produced by gravitational waves in the early Universe. At KICP, she plans to continue working with SPIDER data and to join the analysis efforts for SPT-3G.

Yonatan (Yoni) Kahn received his Ph.D. from MIT in 2015, and spent the past 3 years as a postdoctoral research associate at Princeton University working on new proposals for dark matter detection experiments. As a theoretical physicist with strong connections to the experimental community, Yoni was a driving force behind the ABRACADABRA axion experiment recently launched at MIT, and he hopes to tap into the network of expertise in cosmology at KICP and the wider University of Chicago community to devise new searches for dark matter.

Dan Baxter will receive his PhD from Northwestern University, where he has spent his graduate career working with the PICO collaboration to search for dark matter using bubble chambers. The primary result of his thesis is the first run with C3F8 of the PICO-60 detector, which represented the first background-free run of a bubble chamber dark matter detector at the 40L scale. As a joint KICP and EFI Fellow, he is excited to continue the search for dark matter with the DAMIC collaboration and looks forward to contributing to the numerous rare event searches in the department.

2018 Oppenheimer Lecture with Michael S. Turner

Big ideas like the deep connections between quarks and the cosmos and powerful instruments like the Hubble Space Telescope and Large Hadron Collider have advanced our understanding of the universe. We can now trace its history from the big-bang beginning 13.8 billion years ago through an early state of quantum fluctuations to a soup of quarks and other particles, from the formation of nuclei and atoms to the emergence of stars and galaxies, and finally to its expansion today. This lecture describes what we know, what we are trying to figure out and the excitement of the adventure.

Nora won the DOE SCGSR Fellowship and a URA Visiting Scholars Program award to work with Fermilab scientists on using stellar streams to learn about dark matter in the Milky Way.

"Nora Shipp has carried out an analysis of the wide-field distribution of stars in the Dark Energy Survey (DES) footprint on the sky and identified several known stellar streams and discovered new streams. Stellar streams are an "archeological" record of the accretion history of the Milky Way and can be used as probes of properties of dark matter and of the Milky Way gravitational potential.

This project resulted in a paper that presented one of the most spectacular scientific results of the first year DES data and the results were a subject of a number of press releases and were widely covered in the media. In collaboration with DES scientists at Fermilab, Nora is continuing to characterize the streams analyzed in the DES and is planning to search for gaps in the streams and to model them using techniques developed by a former KICP student, Denis Erkal, as part of his postdoc work with Vasily Belokurov at Cambridge. Nora also plans to carry out N-body simulations for more detailed modeling of the streams. This program can potentially provide a new and unique probe of existence of dark matter clumps of mass $approx 10^6-10^7$ solar masses in the Milky Way, thereby constraining properties of dark matter itself, and to constrain properties of the Milky Way potential itself. DoE and URA fellowships that Nora received will help to carry out the first stages of this longer term PhD thesis program."

Results from XENON1T, the world's largest and most sensitive detector dedicated to a direct search for Dark Matter in the form of Weakly Interacting Massive Particles (WIMPs), are reported today (Monday, 28th May) by the spokesperson, Prof. Elena Aprile of Columbia University, in a seminar at the hosting laboratory, the INFN Laboratori Nazionali del Gran Sasso (LNGS), in Italy. The international collaboration of more than 165 researchers from 27 institutions, has successfully operated XENON1T, collecting an unprecedentedly large exposure of about 1 tonne x year with a 3D imaging liquid xenon time projection chamber. The data are consistent with the expectation from background, and place the most stringent limit on spin-independent interactions of WIMPs with ordinary matter for a WIMP mass higher than 6 GeV/c². The sensitivity achieved with XENON1T is almost four orders of magnitude better than that of XENON10, the first detector of the XENON Dark Matter project, which has been hosted at LNGS since 2005. Steadily increasing the fiducial target mass from the initial 5 kg to the current 1300 kg, while simultaneously decreasing the background rate by a factor 5000, the XENON collaboration has continued to be at the forefront of Dark Matter direct detection, probing deeper into the WIMP parameter space.

UChicago, Luca Grandi's group

"I am really happy with the performance of the XENON1T detector" said Luca Grandi. "XENON1T displays an impressive sensitivity to WIMP spin-independent interaction, about 7 times better than the concurrent leading experiments in the field (for WIMP masses above 6 GeV/c^2). This result shows the potential of combining multi-tonne detectors with low background techniques. Despite this accomplishment, dark matter remains still to be discovered. The search continues!".

The contributions of Grandi's group to the XENON projects included several activities. After the initial contribution to the construction and assembly of the XENON1T Time Projection Chamber, the group worked hard to make UChicago the single analysis hub serving the entire international collaboration. The system, developed in collaboration with Robert Gardner and Benedikt Riedel at the UChicago Computational Institute, allows for easy access both to remote grid resources (needed to process the large data volume produced by XENON1T) and local resources available at the UChicago Research Computing Center. The latter, thanks to the support from Runesha Birali and KICP, have been intensively used in these last several months to converge on the results presented in the paper. The UChicago group, with its postdoc Jacques Pienaar and graduate students Katrina Miller and Evan Shockley, contributed to several aspects of the presented analysis, including the development of the neutron background models and Monte Carlo simulations and the study of the response and efficiency of the detector at low energy. The group will continue its involvement in XENON1T analysis by searching for alternative dark matter candidates.

In the meanwhile Grandi's group is also heavily involved in the upgrade of the detector to the next phase, known as XENONnT, which will feature a fiducial target mass about 4 times larger and is expected to start data taking in about one year from now. The group, with support from Ben Stillwell at the Enrico Fermi Institute, is leading the design of the new Time Projection Chamber, coordinating its production and assembly, as well as preparing the upgrade of the data processing infrastructure to allow the handling of the even larger data volumes. The larger fiducial mass and the implementation of new innovative techniques will enable further suppression of the already ultra-low background levels, and will allow XENONnT to further explore the WIMP paradigm and improve its sensitivity by about an order of magnitude. "Dark Matter is still out there" Grandi concludes "... and we will do our best to continue to stay on the front line of this uncharted territory!"

World-renowned scientist Martin Rees offers his look at the future of humanity and science in this talk based upon his new book On the Future: Prospects for Humanity. Rees argues that humanity's future is bound to the future of science, and our prospects hinge on how successfully we harness technological advances to address the challenges to our collective future. If we are to use science to solve our problems while avoiding its dystopian risks, Rees shows how we must think rationally, globally, collectively, and optimistically about the long-term future. Advances in biotechnology, cybertechnology, robotics, and artificial intelligence - if pursued and applied wisely- could empower us to boost the developing and developed world and overcome the threats humanity faces on Earth, from climate change to nuclear war. Rees offers fascinating insights into cutting-edge science and technology while providing a unique perspective on the critical issues that will define the future of humanity on Earth and beyond.

Presented in collaboration with the Chicago Public Library.

Doors to the Cindy Pritzker Auditorium open at 5 p.m. and seating is available first come, first served. The event is free but registration is recommended. Books are available for purchase from Seminary Co-op Books and the author will autograph books at the conclusion of the program.

A special event for the Bulletin of the Atomic (Cafe) Scientists at the Sunday, September 23, 5:30 screening - atomic cocktails before and Questions and Answers with the Auteur Herself after.

Artfully culled from newsreel footage, government archives, and pop-culture artifacts (cocktails, fashions, cartoons, jukebox songs, etc.), THE ATOMIC CAFE is a mind-boggling compendium of misinformation that was aimed at selling nuclear war to the postwar American public like a new brand of laundry detergent. As singing Polynesians are evacuated from Bikini Atoll and Burt the Turtle tells schoolchildren how to "Duck and Cover," public officials promote a devil-may-care attitude toward the dangers of nuclear attack and radioactive fallout. This groundbreaking, often-imitated documentary created a sensation when first released in 1982; now, with fake news in ascendancy, and the "Bulletin of Atomic Scientists" famous Doomsday Clock set at its furthest point (two minutes to midnight) since 1953, it seems as timely as ever.
