We are truly in the era of Big Data. The number of data science and analytics job openings has grown rapidly over the past several years and demand looks to continue to be very strong in the years to come. Masters and PhD scientists (from all quantitative fields) are extremely well-qualified for such positions. I will discuss the basics of what data science is and what data scientists do, as well as how scientists in academia can become successful candidates for these positions in the tech industry. I'll also share my personal path from NSF astronomy postdoc to gainfully-employed data scientist.

Carlos Frenk, University of Durham, "How our universe was made: all from nothing"
May 14, 2020 cancelled | SAIC MacLean Ballroom | 112 S. Michigan Avenue, Chicago | 6:00 PM | Event
CANCELLED

Carlos S. Frenk, 2020 Brinson Lecturer
Professor Carlos S. Frenk is Director of the Institute for Computational Cosmology, Durham University's world-renowned theoretical cosmology research group. Along with collaborators from all over the world, he builds model universes in state-of-the-art supercomputers, trying to understand how the structures in our Universe evolved from simple beginnings to the complex structures composed of stars and galaxies that we see today.

2020 Brinson Lecture: "How our universe was made: all from nothing"
Cosmology addresses some of the most fundamental questions in science. How and when did our universe begin? What is it made of? How did galaxies and other structures form? There has been enormous progress in the past few decades towards answering these questions. For example, recent observations have established that our universe contains an unexpected mix of components: ordinary atoms, exotic dark matter and a new form of energy called dark energy. Gigantic surveys of galaxies reveal how the universe is structured. Large supercomputer simulations can recreate the evolution of the universe in astonishing detail and provide the means to relate processes occurring near the beginning with observations of the universe today. A coherent picture of cosmic evolution, going back to a tiny fraction of a second after the Big Bang, is beginning to emerge. However, fundamental issues, like the identity of the dark matter and the nature of the dark energy, remain unresolved.Large supercomputer simulations can recreate the evolution of the universe in astonishing detail and provide the means to relate processes occurring near the beginning with observations of the universe today.

Elias Oakes, "The Distance to the Fornax dSph via the Tip of the Red Giant Branch and Horizontal Branch Stars"

Host: Rich Kron

Abstract: The Hubble constant (H0) tension stands at a more than 4σ discrepancy between measurements from the local distance ladder and the cosmic microwave background, with no physical explanation in sight. This tension motivates the development of an independent path to H0, to cross-reference existing distance measurements and control for systematics. The Carnegie-Chicago Hubble Program (CCHP) is approaching this problem by using Population II stars to establish an accurate and precise cosmic distance scale that is independent of, but parallel to, the well-established and commonly known Population I path using Cepheid variables. In this work, we determine the distance to the Fornax dwarf spheroidal (dSph) galaxy using three independent Population II distance methods: the Tip of the Red Giant Branch (TRGB), RR Lyrae period-luminosity and period-Wesenheit relations, and the magnitude of the Zero-Age Horizontal Branch (ZAHB) envelope. Using wide-field, ground-based imaging data, obtained at the Magellan 6.5m telescope at Las Campanas, Chile, we measure a TRGBbased distance modulus of μTRGB = 20.84 ± 0.06 mag, RR Lyrae distance modulus of μRRL = 20.75 ± 0.1 mag using archival variable star surveys, and ZAHB distance modulus of μZAHB = 20.81 ± 0.02 mag. Averaging these measurements yields a combined distance modulus of μ = 20.80±0.04 mag, which is consistent with an extensive catalog of published distance measurements to Fornax.

LNGS seminar: Evan Shockley, University of Chicago, "Search for New Physics with Electronic-Recoil Events in XENON1T"
June 17, 2020 | Online | 9:00 AM | Event
Chair: Stefano Ragazzi (LNGS Director)

We report results from searches for new physics with low-energy electronic recoil data recorded with the XENON1T detector. With an exposure of 1042 kg x 226.9 days and an unprecedented low background rate of (76 2) events/(tonne x year x keV) between 1-30 keV, the data enables the most sensitive searches for new physics such as solar axions, an enhanced neutrino magnetic moment using solar neutrinos, and bosonic dark matter.

Journal of Plasma Physics colloquium: Irina Zhuravleva (UChicago), "Physics of the hot plasma in galaxy clusters with present and future X-ray observations"
June 17, 2020 | Zoom (online) | 10:00 AM | Event
The Journal of Plasma Physics has organized a world-wide colloquium series on topics in the frontiers of plasma physics. This Wed. June 17 at 10 am, Irina Zhuravleva will be giving a talk at 10 am as part of the series.

Irina Zhuravleva, UChicago, "Physics of the hot plasma in galaxy clusters with present and future X-ray observations"

The intracluster medium (ICM) between galaxies in galaxy clusters is in a form of hot, X-ray-emitting plasma, permeated by weak magnetic fields. Although the magnetic fields are energetically subdominant, they modify the transport properties of the plasma, and, thereby, many large-scale phenomena in the ICM: from feedback processes to cluster mergers and subsequent energy flow and heating. The large sizes and relative simplicity of galaxy clusters make them ideal laboratories for measuring fundamental properties of such plasma, which are inaccessible by other means. In this talk, I will review how high-resolution imaging and spectroscopic data from X-ray observations are used to probe turbulence, gas viscosity, and thermal conduction in the ICM. I will present recent constraints on the effective gas viscosity in the bulk intergalactic plasma based on the observed density fluctuations on the Coulomb mean free path scale. At the end of the talk, exciting possibilities to probe plasma physics with near-future XRISM observatory will be discussed.

Early career job market
June 23, 2020 | Zoom Room (online) | 12:00 PM | Event
Dear KICP, EFI, and A&A members,

We are all going through a very stressful time with recent events at home and across the globe. Among other things, a particular point of anxiety for our early career members is how the academic job landscape will be reshaped as a result of the COVID-19 epidemic.

To start the dialogue we, along with the IDEA group and directors of the KICP, EFI, A&A, would like to invite you to a townhall meeting on Tuesday, June 23 at 12-1pm CT via the KICP Zoom Room . Although the discussion will be informal and we encourage contributions from all in attendance, the conversation will be lead by student/postdoc moderators and faculty panelists:

Abby Vieregg (Physics, KICP, EFI)

Alex Drlica-Wagner (A&A, KICP, Fermilab)

Tom Crawford (A&A, KICP)

Young-Kee Kim (Physics Chair, EFI, DPF Chair)

Fully recognizing that no one will have all of the answers, our goal is to provide a space where both early career members can ask questions about postdoc/faculty hiring and senior members can better understand how to adjust their mentorship strategies. With this foundation, we can all feel more empowered to prepare for the future and address resources that can help support our decisions.

To give our panel preparation material, we will collect anonymous questions/thoughts via form. This poll will close on Monday, June 15. Please stay well and hope to see you there!

Yours sincerely,

Danielle Norcini (KICP, EFI, & Physics)

Gourav Khullar (A&A, KICP)

Webinar: LIGO-Virgo Finds Mystery Object in "Mass Gap" (GW190814)
June 25, 2020 | Online | 9:00 AM | Event
In August of 2019, the LIGO-Virgo gravitational-wave network witnessed the merger of a black hole with 23 times the mass of our sun and a mystery object 2.6 times the mass of the sun. Scientists do not know if the mystery object was a neutron star or black hole, but either way it set a record as being either the heaviest known neutron star or the lightest known black hole.

You can find the paper at https://arxiv.org/abs/2006.12611 or in ApJL at https://iopscience.iop.org/article/10.3847/2041-8213/ab960f.

Website
Owing to the ongoing COVID-19 pandemic the CMB-S4 workshop will be held entirely remotely, August 10 - 14, 2020. The meeting is open to everyone interested in the broad range of cosmology and astrophysics that CMB-S4 will impact. Registration is free.

This, the 11th workshop in the series of twice yearly CMB-S4 workshops, will focus on the CMB-S4 science case in conjunction with other experiments and probes. A key goal of the workshop is to engage with the broad community that is addressing science topics similar to those being pursued with CMB-S4, but using different techniques. We will discuss how CMB-S4 measurements can be used to advance these science topics in unique and complementary ways, and work on exploring powerful joint analysis of CMB and other probes.
