EFI seminar: Nahee Park, University of Wisconsin, "Probing high energy particle dynamics in our Galaxy with multimessenger observations"
Cosmic rays, high energy particles originating from outside of the solar system, are believed to be dominated by particles from our Galaxy at least up to the energy of 10^15 eV. Since their discovery in 1912, the origin, acceleration, and propagation of these high energy particles have remained as open questions. In the last few years, new results from space-borne experiments, such as the rise of the positron flux and hardening of the light nuclei, have begun to challenge our understanding of these particles. Complementing this, indirect observations of the cosmic rays via very high energy gamma rays have started to shed light on the various particle accelerators in our Galaxy with discoveries of over a hundred Galactic sources. With the recent detection of astrophysical neutrinos by IceCube, the first unequivocal view of pure hadronic accelerators in our Universe became available. I will present what we have learned about the acceleration of high energy particles with gamma-ray observations based on the Galactic gamma-ray measurements from the VERITAS experiment, an imaging atmospheric Cherenkov telescope. I will show what we can learn from the future neutrino experiment IceCube Gen-2 and the future gamma-ray observatory CTA. Finally, I will highlight how these multimessenger observations come together to lead us toward a more coherent and complete picture of high energy particles in our Galaxy.
Workshop: Towards Dark Matter Discovery
The Kavli Institute of Cosmological Physics (KICP) at the University of Chicago is hosting the "Towards Dark Matter Discovery" workshop, which will be held from 11th to 13th April 2018 in the Eckhardt Research Center (ERC) on the University of Chicago campus.
The workshop will explore new directions on the path toward discovering the nature of dark matter. The invited speakers are encouraged to share their expertise in the fields of primordial black holes, thermal relic dark matter, nonthermal relic dark matter, ultralight dark matter, superheavy dark matter, kinda-chubby dark matter, new strategies for direct detection, newer strategies for direct detection, avant-garde strategies for direct detection, and axions. During the three day workshop, we will host approximately 20 talks of 30 minutes each with generous time remaining for discussion.
Visitors to the University of Chicago are invited to spend the entire week at the university.

Spring 2018 Postdocs Symposium
Richard Ellis, "Let There Be Light: The Observational Quest for the First Galaxies"
Richard Ellis, 2018 Brinson Lecturer
Richard Ellis is Professor of Astrophysics at the University College London. Until recently he was the Steele Professor of Astronomy at the California Institute of Technology (Caltech). He was awarded the 2011 Gold Medal of the Royal Astronomical Society. Ellis works primarily in observational cosmology, considering the origin and evolution of galaxies, the evolution of large scale structure in the universe, and the nature and distribution of dark matter. He worked on the Morphs collaboration studying the formation and morphologies of distant galaxies. Particular interests include applications using gravitational lensing and high-redshift supernovae. He was a member of the Supernova Cosmology Project whose leader, Saul Perlmutter, shared the 2011 Nobel Prize for Physics for the team's surprising discovery of the accelerating expansion of the Universe. His most recent discoveries relate to searches for the earliest known galaxies, seen when the Universe was only a few percent of its present age.
2018 Brinson Lecture: "Let There Be Light: The Observational Quest for the First Galaxies"
The first billion years after the Big Bang is widely regarded as the final observational frontier in assembling a complete picture of cosmic history. During this period early stars and galaxies formed and the Universe became bathed in light for the first time. Hydrogen clouds in the space inbetween galaxies transformed from an atomic gas to a fully ionized medium consisting of detached protons and electrons. How and when did this 'cosmic reionization' occurred and were early star-forming galaxies the primary agents? Recent progress has raised the exciting prospect that we will soon be able to directly witness this dramatic period when the Universe emerged from darkness and the first galaxies began to shine. Professor Ellis will review the rapid progress being made with current facilities, and the prospects with upcoming ones, including the James Webb Space Telescope and extremely large ground-based telescopes now under construction. The motivation is fundamental: the origin of starlight begins the process of chemical evolution which ultimately leads to our own existence in this remarkable Universe.
This event is co-sponsored by the University of Chicago and the School of the Art Institute of Chicago.

Workshop: Joint SPT-DES Analysis
The Kavli Institute of Cosmological Physics (KICP) at the University of Chicago is hosting the "SPTxDES Joint Analysis" workshop, which will be held from 20th to 22nd June 2018 in the Eckhardt Research Center (ERC) on the University of Chicago campus.
This workshop focuses on the science at the intersection of two leading cosmology experiments---the Dark Energy Survey (DES) and the South Pole Telescope (SPT) - with the goal of optimal extraction of cosmological constraints from these two surveys.
The workshop would serve as both a forum for discussions on current analyses as well as an incubator for future ideas. The meeting will cover two main themes: galaxy clusters and wide-field science. While these topics cover a broad spectrum, we will target the workshop such that it accelerates joint work on these key areas of synergy between the two collaborations.
Workshop: Near-Field Cosmology with the Dark Energy Survey's DR1 and Beyond
Stars in our Milky Way and galaxies in our Local Group contain the fossils and clues on stellar evolution and supernovae, the formation and evolution of star clusters and dwarf galaxies, and the formation of large spiral galaxies. Rapid progress in this field -- usually called Galactic Archeology -- was enabled by large-area imaging and spectroscopic surveys of old stellar components of the Milky Way and dwarf galaxies, together with simulations of chemical and dynamical evolution. The field of Near-Field Cosmology extends the scope of these studies to probe the formation and evolution of galaxies and the nature of dark matter.
The Dark Energy Survey (DES) is releasing its DR1, with catalogs and images from the first three years of DES operations early in 2018, including 400M objects (100M stellar sources in grizY band to r of 24th magnitude at 10 sigma) over 5000 square degrees mostly in the Southern Galactic cap. This survey is about 2 magnitudes fainter than SDSS at the same S/N. In addition to DES, many other DECam community surveys, such as DECaLS, DECaPS, SMASH, MagLiteS, BLISS, etc, have already had or will soon have the public data release.
Kavli Institute for Cosmological Physics (KICP) at the University of Chicago will host a 3-day workshop on June 27-29 to explore uses of the DES DR1 for near field cosmology studies in conjunction with other DECam public data. Furthermore, the workshop will explore possible synergies with other spectroscopic surveys as well as Gaia DR2.
The 3-day workshop will include presentations and discussion on the first two days and a hack day on the last day. Talks on ideas or science results related to DES/DECam data, or synergies with other programs are encouraged. Abstracts can be submitted at registration. On the hack day, we will hack on DES DR1 data and associated data sets (like Gaia DR2) in a collaborative format. Specific hack topics can be submitted at registration.
Topics in this workshop includes:
Soapbox Science is an international, grass-roots science outreach organization that brings cutting edge research to urban settings while also promoting the visibility of women in science. We place inspirational female speakers on soapboxes (literally!) and encourage them to engage in and start conversations with the public about their work. This is a free event where our female scientists will interact with visitors to Navy Pier, busker style, telling them about everything from ecology to mathematics to astrophysics.
This summer, 30 Soapbox Science events are being held across the world. Chicago will be the first ever United States location. Our event will occur on Saturday July 21 from 12-3pm at Chicago's iconic Navy Pier. We have selected 12 outstanding Chicago-based early career women in STEM, who are ready to wow Chicagoland with their ground-breaking research.
Soapbox Science is not just about the speakers. Without a supportive team of committed, enthusiastic people, a Soapbox event simply cannot happen. Each event relies on an animated team of up to 20 volunteers. Volunteers play a crucial role in rounding up the public, chatting to them informally about science, and supporting the speakers by managing props. But perhaps the most important role of the volunteers is gathering data so we can effectively monitor the success of the event: volunteers carry out the bulk of our streamlined evaluation process, through interviews, observations and counting footfall.
KICP Summer Institute: City of Tomorrow
Our world is changing rapidly. What will tomorrow look like? As we strive to take care of this planet, we also look to the stars, to other planets. We explore the far reaches of space for our curiosity, for discovery - also, possibly for another home for our species. How would we provide energy for a civilization on another planet? How do we approach ethics and justice in this new civilization? This year, teams of student researchers will design unique proposals for energy infrastructure on three kinds of extraterrestrial systems - a planet, a moon, and a space ship.

Workshop: The Future of H0: Crisis or Concordance?
Just in the last two years, we have seen the final Planck data release, measurements of the local value of the Hubble constant nearing two percent, the first standard siren measurement, and new strong lens time delay cosmological measurements. Even with a number of re-analyses and systematic checks on these various analyses, tension of the local Ho measurements and the CMB inferred Ho value remains, and excitement continues to increase amongst cosmologists regarding the source of tension. In this workshop, we are asking what's next for all these experiments and analyses. This workshop will be focused on analyses coming out in the next year or two, looking at what we can expect before the next generation of experiments come online. We want to hear about new ideas to push down at systematic uncertainties in current analyses, what lingering issues remain unresolved and what can be done to solve them. This workshop will be a unique chance for scientists who work on different probes to think together about what can be done to better understand what is driving the tension and how the next round of analyses can address various concerns.
Workshop: The Magnificent CEvNS
With the observation of coherent elastic neutrino-nucleus scattering (CEvNS, pronounced "sevens") now realized, there is a groundswell of efforts in and around the process. This workshop will bring together theorists, phenomenologists, and experimentalists from the CEvNS community with the goal of exploring upcoming experiments, the complementarity between them, and the broad range of physics questions that CEvNS can address. The current landscape of ongoing or potential CEvNS experiments will be surveyed, and discussion will be fostered about the physics topics that can be most powerfully or uniquely addressed by this process. By bringing together theory and experiment workers at this exciting moment, we hope to enrich the exchanges within the CEvNS community, with the goal of defining and guiding future common efforts that maximize the physics impact of this process.
The workshop will be co-hosted by the Enrico Fermi Institute (EFI) and the Kavli Institute for Cosmological Physics (KICP), and will take place on the University of Chicago campus at the newly renovated Physics Research Center (PRC), home of the EFI.
