Ring objects in the equivariant derived Satake category arising from Coulomb branches (with an appendix by Gus Lonergan)

Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Alexander Braverman, Michael Finkelberg, Hiraku Nakajima, , | Summary: This is the second companion paper of arXiv:1601.03586. We consider the morphism from the variety of triples introduced in arXiv:1601.03586 to the affine Grassmannian. The direct image of the dualizing complex is a ring object in the equivariant […]

Two- and Three-Dimensional Probes of Parity in Primordial Gravity Waves

Kavli Affiliate: Kiyoshi Wesley Masui | First 5 Authors: Kiyoshi Wesley Masui, Ue-Li Pen, Neil Turok, , | Summary: We show that three-dimensional information is critical to discerning the effects of parity violation in the primordial gravity-wave background. If present, helical gravity waves induce parity-violating correlations in the cosmic microwave background (CMB) between parity-odd polarization […]

The compact, ~1 kpc host galaxy of a quasar at z=7.1

Kavli Affiliate: R. G. McMahon | First 5 Authors: Bram Venemans, Fabian Walter, Roberto Decarli, Eduardo Banados, Jacqueline Hodge | Summary: We present ALMA observations of the [CII] fine structure line and the underlying far-infrared (FIR) dust continuum emission in J1120+0641, the most distant quasar currently known (z=7.1). We also present observations targeting the CO(2-1), […]

Massively Parallel Computation of Accurate Densities for N-body Dark Matter Simulations using the Phase-Space-Element Method

Kavli Affiliate: Ralf Kaehler | First 5 Authors: Ralf Kaehler, , , , | Summary: This paper presents an accurate density computation approach for large dark matter simulations, based on a recently introduced phase-space tessellation technique and designed for massively parallel, heterogeneous cluster architectures. We discuss a memory efficient construction of an oct-tree structure to […]

A pair of Calabi-Yau manifolds from a two parameter non-Abelian gauged linear sigma model

Kavli Affiliate: Kentaro Hori | First 5 Authors: Kentaro Hori, Johanna Knapp, , , | Summary: We construct and study a two parameter gauged linear sigma model with gauge group $(U(1)^2times O(2))/{mathbb Z}_2$ that has a dual model with gauge group $(U(1)^2times SO(4))/{mathbb Z}_2$. The model has two geometric phases, three hybrid phases and one […]

Wavelet-Based Characterization of Small-Scale Solar Emission Features at Low Radio Frequencies

Kavli Affiliate: Robert Goeke | First 5 Authors: Akshay Suresh, Rohit Sharma, Divya Oberoi, Srijan B. Das, Victor Pankratius | Summary: Low radio frequency solar observations using the Murchison Widefield Array have recently revealed the presence of numerous weak, short-lived and narrow-band emission features, even during moderately quiet solar conditions. These non-thermal features occur at […]

SuperCDMS SNOLAB Low-Mass Detectors: Ultra-Sensitive Phonon Calorimeters for a Sub-GeV Dark Matter Search

Kavli Affiliate: Paul Brink | First 5 Authors: Noah Kurinsky, Paul Brink, Richard Partridge, Blas Cabrera, Matt Pyle | Summary: We present the technical design for the SuperCDMS high-voltage, low-mass dark matter detectors, designed to be sensitive to dark matter down to 300 MeV/$c^2$ in mass and resolve individual electron-hole pairs from low-energy scattering events […]

Red nuggets grow inside-out: evidence from gravitational lensing

Kavli Affiliate: Philip Marshall | First 5 Authors: Lindsay Oldham, Matt Auger, Chris Fassnacht, Tommaso Treu, Brendon J. Brewer | Summary: We present a new sample of strong gravitational lens systems where both the foreground lenses and background sources are early-type galaxies. Using imaging from HST/ACS and Keck/NIRC2, we model the surface brightness distributions and […]

GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey I: A low-frequency extragalactic catalogue

Kavli Affiliate: Edward Morgan | First 5 Authors: Natasha Hurley-Walker, Joseph R. Callingham, Paul J. Hancock, Thomas M. O. Franzen, Luke Hindson | Summary: Using the Murchison Widefield Array (MWA), the low-frequency Square Kilometre Array (SKA1 LOW) precursor located in Western Australia, we have completed the GaLactic and Extragalactic All-sky MWA (GLEAM) survey, and present […]
