Wave train selection by invasion fronts in the FitzHugh--Nagumo equation
Paul Carter, Arnd Scheel
We study invasion fronts in the FitzHugh--Nagumo equation in the oscillatory regime using singular perturbation techniques. Phenomenologically, localized perturbations of the unsta…
The HR 4796A Debris System: Discovery of Extensive Exo-Ring Dust Material
Glenn Schneider, John H. Debes, Carol A. Grady +6
The optically and IR bright, and starlight-scattering, HR 4796A ring-like debris disk is one of the most (and best) studied exoplanetary debris systems. The presence of a yet-undet…
Developing post-coronagraphic, high-resolution spectroscopy for terrestrial planet characterization on ELTs
N. Jovanovic, O. Guyon, T. Kotani +12
Spectroscopic observations are extremely important for determining the composition, structure, and surface gravity of exoplanetary atmospheres. High resolution spectroscopy of the…
Addendum: Étale dévissage, descent and pushouts of stacks
Jack Hall, David Rydh
Using Nisnevich coverings and a Hilbert stack of stacky points, we prove étale dévissage results for non-representable étale and quasi-finite flat coverings. We give applications t…
Evidence of a truncated spectrum in the angular correlation function of the cosmic microwave background
Fulvio Melia, Martin Lopez-Corredoira
The lack of large-angle correlations in the fluctuations of the cosmic microwave background (CMB) conflicts with predictions of slow-roll inflation. But though probabilities (< 0.2…
Atmospheric Circulations of Hot Jupiters as Planetary Heat Engines
Daniel D. B. Koll, Thaddeus D. Komacek
Because of their intense incident stellar irradiation and likely tidally locked spin states, hot Jupiters are expected to have wind speeds that approach or exceed the speed of soun…
GUT Precursors and Entwined SUSY: The Phenomenology of Stable Non-Supersymmetric Strings
Steven Abel, Keith R. Dienes, Eirini Mavroudi
Recent work has established a method of constructing non-supersymmetric string models that are stable, with near-vanishing one-loop dilaton tadpoles and cosmological constants. Thi…
The First 3D Simulations of Carbon Burning in a Massive Star
Andrea Cristini, Casey Meakin, Raphael Hirschi +3
We present the first detailed three-dimensional hydrodynamic implicit large eddy simulations of turbulent convection for carbon burning. The simulations start with an initial radia…
Precision Time-series Photometry in the Thermal Infrared with a 'Wall-Eyed' Pointing Mode at the Large Binocular Telescope
Eckhart Spalding, Phil Hinz, Andrew Skemer +3
Time-series photometry taken from ground-based facilities is improved with the use of comparison stars due to the short timescales of atmospheric-induced variability. However, the…
Spatially Resolved Dust, Gas, and Star Formation in the Dwarf Magellanic Irregular NGC4449
D. Calzetti, G. W. Wilson, B. T. Draine +17
We investigate the relation between gas and star formation in sub-galactic regions, ~360 pc to ~1.5 kpc in size, within the nearby starburst dwarf NGC4449, in order to separate the…
Emergence of Fourier's law of heat transport in quantum electron systems
Sosuke Inui, Charles A. Stafford, Justin P. Bergfield
The microscopic origins of Fourier's venerable law of thermal transport in quantum electron systems has remained somewhat of a mystery, given that previous derivations were forced…
The distribution and ages of star clusters in the Small Magellanic Cloud: Constraints on the interaction history of the Magellanic Clouds
T. Bitsakis, R. A. Gonzalez-Lopezlira, P. Bonfini +5
We present a new study of the spatial distribution and ages of the star clusters in the Small Magellanic Cloud (SMC). To detect and estimate the ages of the star clusters we rely o…
X-ray/UV/optical variability of NGC 4593 with Swift: Reprocessing of X-rays by an extended reprocessor
I M McHardy, S D Connolly, K Horne E M Cackett +25
We report the results of intensive X-ray, UV and optical monitoring of the Seyfert 1 galaxy NGC 4593 with Swift. There is no intrinsic flux-related spectral change in the the varia…
VALES: IV. Exploring the transition of star formation efficiencies between normal and starburst galaxies using APEX/SEPIA Band-5 and ALMA at low redshift
C. Cheng, E. Ibar, T. M. Hughes +12
In this work we present new APEX/SEPIA Band-5 observations targeting the CO () emission line of 24 Herschel-detected galaxies at . Combining this sample {w…
A Hubble Space Telescope Imaging Study of Four FeLoBAL Quasar Host Galaxies
Daniel Lawther, Marianne Vestergaard, Xiaohui Fan
We study the host galaxies of four Iron Low-Ionization Broad Absorption-line Quasars (FeLoBALs) using Hubble Space Telescope imaging data, investigating the possibility that they r…
Confronting Models of Massive Star Evolution and Explosions with Remnant Mass Measurements
Carolyn A. Raithel, Tuguldur Sukhbold, Feryal Özel
The mass distribution of compact objects provides a fossil record that can be studied to uncover information on the late stages of massive star evolution, the supernova explosion m…
Calibration of the island effect: Experimental validation of closed-loop focal plane wavefront control on Subaru/SCExAO
Mamadou N'Diaye, Frantz Martinache, Nemanja Jovanovic +5
Island effect (IE) aberrations are induced by differential pistons, tips, and tilts between neighboring pupil segments on ground-based telescopes, which severely limit the observat…
Chiral Anomalous Dispersion
Andrey Sadofyev, Srimoyee Sen
The linearized Einstein equation describing graviton propagation through a chiral medium appears to be helicity dependent. We analyze features of the corresponding spectrum in a co…
Simultaneous, Multi-Wavelength Variability Characterization of the Free-Floating Planetary Mass Object PSO J318.5-22
Beth Biller, Johanna Vos, Esther Buenzli +15
We present simultaneous HST WFC3 + Spitzer IRAC variability monitoring for the highly-variable young (20 Myr) planetary-mass object PSO J318.5-22. Our simultaneous HST + Spit…
Upper atmospheres and ionospheres of planets and satellites
Antonio García Muñoz, Tommi T. Koskinen, Panayotis Lavvas
The upper atmospheres of the planets and their satellites are more directly exposed to sunlight and solar wind particles than the surface or the deeper atmospheric layers. At the a…
