Kavli Affiliate: Luis Ho | First 5 Authors: Yue Shen, Scott Anderson, Edo Berger, W. N. Brandt, Gisella De Rosa | Summary: The ubiquitous variability of quasars across a wide range of wavelengths and timescales encodes critical information about the structure and dynamics of the circumnuclear emitting regions that are too small to be directly […]
Kavli Affiliate: Patricia R. Burchat | First 5 Authors: Keith Bechtol, Alex Drlica-Wagner, Kevork N. Abazajian, Muntazir Abidi, Susmita Adhikari | Summary: Astrophysical observations currently provide the only robust, empirical measurements of dark matter. In the coming decade, astrophysical observations will guide other experimental efforts, while simultaneously probing unique regions of dark matter parameter space. […]
Kavli Affiliate: A. C. Davis | First 5 Authors: Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido, A. Kashlinsky, L. Wyrzykowski | Summary: The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1) the observed merger rate of […]
Kavli Affiliate: Nickolay Gnedin | First 5 Authors: Enrico Garaldi, Nickolay Gnedin, Piero Madau, , | Summary: We investigate Lyman-$alpha$ transmission spikes at $z > 5$ in synthetic quasar spectra, and discuss their connection to the properties of the intergalactic medium and their ability to constrain reionization models. We use state-of-the-art radiation-hydrodynamic simulations from the […]
Kavli Affiliate: Robert J. Wood | First 5 Authors: Neel Doshi, Kaushik Jayaram, Samantha Castellanos, Scott Kuindersma, Robert J Wood | Summary: Limitations in actuation, sensing, and computation have forced small legged robots to rely on carefully tuned, mechanically mediated leg trajectories for effective locomotion. Recent advances in manufacturing, however, have enabled the development of […]
Kavli Affiliate: Mark Hartz | First 5 Authors: Aysel Kayis Topaksu, Edward Blucher, Bernard Andrieu, Jianming Bian, Byron Roe | Summary: With the discovery of non-zero value of $theta_{13}$ mixing angle, the next generation of long-baseline neutrino (LBN) experiments offers the possibility of obtaining statistically significant samples of muon and electron neutrinos and anti-neutrinos with […]
Kavli Affiliate: Rafe Schindler | First 5 Authors: Joseph DeRose, Risa H. Wechsler, Matthew R. Becker, Michael T. Busha, Eli S. Rykoff | Summary: We present a suite of 18 synthetic sky catalogs designed to support science analysis of galaxies in the Dark Energy Survey Year 1 (DES Y1) data. For each catalog, we use […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, , , , | Summary: This lecture series consists of mostly independent three parts: Part 1: a tour of basic 4d N=1 supersymmetric dynamics, covering the pure super Yang-Mills, the Seiberg duality for classical groups, the supersymmetric index on S^3, and the a-maximization. Part 2: […]
Kavli Affiliate: Eric Peng | First 5 Authors: Eric Emsellem, Remco F. J. van der Burg, Jeremy Fensch, Tereza Jerabkova, Anita Zanella | Summary: The so-called ultra-diffuse galaxy NGC~1052-DF2 was announced to be a galaxy lacking dark matter based on a spectroscopic study of its constituent globular clusters. Here we present the first spectroscopic analysis […]
Kavli Affiliate: Radhika Nagpal | First 5 Authors: Daniel S. Calovi, Paul Bardunias, Nicole Carey, J. Scott Turner, Radhika Nagpal | Summary: Termite colonies construct towering, complex mounds, in a classic example of distributed agents coordinating their activity via interaction with a shared environment. The traditional explanation for how this coordination occurs focuses on the […]
