Danielle Norcini will receive her Ph.D. from the Wright Laboratory at Yale University in particle/nuclear physics. She helped lead the R&D and construction of the PROSPECT detector to measure neutrinos at very short distances from a nuclear reactor in a challenging background environment. Her thesis details a search for sterile neutrino oscillations and the world-leading measurement of the uranium-235 antineutrino energy spectrum. As a KICP and Grainger fellow, she plans to develop instruments to measure astrophysical neutrinos and other cosmic particles, probing fundamental physics and cosmology.

Yiming Zhong

I received my PhD from Stony Brook University in 2016 and I did my first postdoc at Boston University before coming to KICP. As a phenomenologist, I am interested in connecting theory to data. My work centers on the search for light dark matter and dark sectors at accelerator experiments or through observations of small-scale cosmological structure. At KICP, I hope to develop new ways to probe dark matter properties and investigate the puzzling anomalies in current cosmological observations.

Victor Buza

Victor Buza will receive his PhD from Harvard University. For his graduate career, he codeveloped the likelihood analysis framework used to analyze BICEP/Keck/Planck/WMAP data and place the tightest constraints on primordial gravitational wave to date. He was also the author of the performance-based forecasting framework that guided the optimization and design of CMB-S4, and determined the currently proposed baseline CMB-S4 instrument configuration. As a KICP Fellow Victor plans to work closely with the KICP community on theory and analysis for CMB polarization experiments (SPT-3G, BICEP/Keck, CMB-S4) and cross-correlations of CMB data with large-scale structure efforts (DES/LSST).

Jose Maria Ezquiaga

Jose Maria Ezquiaga will receive his PhD from the Universidad Autonoma de Madrid. His research focuses on probing the pillars of the standard cosmological model with gravitational waves. As a KICP and Einstein Fellow, Jose Maria will exploit LIGO's data to constrain the propagation of gravitational waves, the expansion of the Universe and the origin of the observed black-holes, anticipating as well how to improve such tests with the next generation of detectors, specially with the space antenna LISA.

Dear Colleagues,

Please join me in congratulating Don York who has been awarded the Royal Astronomical Society Service Award for Astronomy.

The RAS citation reads:
"Professor Donald York, as the Founding Director of the Sloan Digital Sky Survey (SDSS), was a key figure in the conception, design, construction, and initial operation of one of the most successful astronomical facilities of the 21st century. With its first-ever digital image of the entire northern high galactic latitude sky, homogeneously and painstakingly calibrated in a novel photometric system, plus millions of homogeneously obtained spectra, SDSS has touched every subfield of astronomy.

Multiple studies agree that SDSS is the most cited and most impactful facility in ground-based astronomy, or even all astronomy. More than 7,600 papers refer to SDSS in the title or abstract, and these publications have garnered roughly 400,000 citations. Twenty-five of these papers have 1,000 or more citations, and almost 800 have 100 or more citations.

Professor York enabled one of the most significant astronomical projects of our lifetimes, one that benefits the entire international community, and is a truly deserving recipient of the RAS Service Award."

Congratulations Don!

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.

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.

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!"
