Kavli Affiliate: Mikhail Kapranov | First 5 Authors: Michael Finkelberg, Mikhail Kapranov, Vadim Schechtman, , | Summary: We consider the category of perverse sheaves on a complex vector space smooth with respect to a stratification given by an arrangement of hyperplanes with real equations. As shown in an earlier wotk of two of the authors, […]
Kavli Affiliate: Maria T. Zuber | First 5 Authors: Christopher E. Carr, Noelle C. Bryan, Kendall N. Saboda, Srinivasa A. Bhattaru, Gary Ruvkun | Summary: Parabolic flights provide cost-effective, time-limited access to "weightless" or reduced gravity conditions experienced in space or on planetary surfaces, e.g. the Moon or Mars. These flights facilitate fundamental research – […]
Kavli Affiliate: Ulrich Wiesner | First 5 Authors: Michel Fruchart, Seung-Yeol Jeon, Kahyun Hur, Vadim Cheianov, Ulrich Wiesner | Summary: Soft materials can self-assemble into highly structured phases which replicate at the mesoscopic scale the symmetry of atomic crystals. As such, they offer an unparalleled platform to design mesostructured materials for light and sound. Here, […]
Kavli Affiliate: Tadashi Orita | First 5 Authors: Shin-nosuke Ishikawa, Tadayuki Takahashi, Shin Watanabe, Noriyuki Narukage, Satoshi Miyazaki | Summary: We have developed a system combining a back-illuminated Complementary-Metal-Oxide-Semiconductor (CMOS) imaging sensor and Xilinx Zynq System-on-Chip (SoC) device for a soft X-ray (0.5-10 keV) imaging spectroscopy observation of the Sun to investigate the dynamics of […]
Kavli Affiliate: David Weitz | First 5 Authors: Andrea Montessori, Marco Lauricella, Michele La Rocca, Sauro Succi, Elad Stolovicki | Summary: We present a regularized version of the color gradient lattice Boltzmann (LB) scheme for the simulation of droplet formation in microfluidic devices of experimental relevance. The regularized version is shown to provide computationally efficient […]
Kavli Affiliate: Robert Simcoe | First 5 Authors: T. Emil Rivera-Thorsen, Håkon Dahle, Max Gronke, Matthew Bayliss, Jane Rigby | Summary: We present rest-frame ultraviolet and optical spectroscopy of the brightest lensed galaxy yet discovered, at redshift z = 2.4. This source reveals a characteristic, triple-peaked Lyman {alpha} profile which has been predicted by various […]
Kavli Affiliate: Steven Kahn | First 5 Authors: Jason Rhodes, Robert C. Nichol, Éric Aubourg, Rachel Bean, Dominique Boutigny | Summary: Euclid and the Large Synoptic Survey Telescope (LSST) are poised to dramatically change the astronomy landscape early in the next decade. The combination of high cadence, deep, wide-field optical photometry from LSST with high […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Misao Sasaki, , , | Summary: In view of growing interest in tensor modes and their possible detection, we clarify the definition of tensor modes up to 2nd order in perturbation theory within the Hamiltonian formalism. Like in gauge theory, in cosmology the Hamiltonian is […]
Kavli Affiliate: Edmund Bertschinger | First 5 Authors: David M. Hernandez, Edmund Bertschinger, , , | Summary: Calculating the long term solution of ordinary differential equations, such as those of the $N$-body problem, is central to understanding a wide range of dynamics in astrophysics, from galaxy formation to planetary chaos. Because generally no analytic solution […]
Kavli Affiliate: R. G. McMahon | First 5 Authors: Bram Venemans, Fabian Walter, Roberto Decarli, Carl Ferkinhoff, Axel Weiss | Summary: We present ALMA band 3 observations of the CO(6-5), CO(7-6), and [CI] 369micron emission lines in three of the highest redshift quasar host galaxies at 6.6<z<6.9. These measurements constitute the highest-redshift CO detections to […]
