Linear waves in the interior of extremal black holes II
Dejan Gajic
We consider solutions to the linear wave equation in the interior region of extremal Kerr black holes. We show that axisymmetric solutions can be extended continuously beyond the C…
High Responsivity, Large-Area Graphene/MoS2 Flexible Photodetectors
D. De Fazio, I. Goykhman, M. Bruna +9
We present flexible photodetectors (PDs) for visible wavelengths fabricated by stacking centimetre-scale chemical vapour deposited (CVD) single layer graphene (SLG) and single laye…
Time-Translation Invariance of Scattering Maps and Blue-Shift Instabilities on Kerr Black Hole Spacetimes
Mihalis Dafermos, Yakov Shlapentokh-Rothman
In this paper, we provide an elementary, unified treatment of two distinct blue-shift instabilities for the scalar wave equation on a fixed Kerr black hole background: the celebrat…
On-chip integrated, silicon-graphene plasmonic Schottky photodetector, with high responsivity and avalanche photogain
Ilya Goykhman, Ugo Sassi, Boris Desiatov +8
We report an on-chip integrated metal-graphene-silicon plasmonic Schottky photodetector with 85mA/W responsivity at 1.55 um and 7% internal quantum efficiency. This is one order of…
DC Characterization of a Circular, Epoxy-Impregnated High Temperature Superconducting (HTS) Coil
Di Hu, Mark D. Ainslie, Jordan P. Rush +2
Direct current (DC) characterization of high temperature superconducting (HTS) coils is important for HTS applications, such as electric machines, superconducting magnetic energy s…
A Silicon-Singlet Fission Parallel Tandem Solar Cell Exceeding 100 % External Quantum Efficiency
Luis M. Pazos, Ju Min Lee, Anton Kirch +3
Silicon solar cells dominate the solar cell market with record lab efficiencies reaching almost 26%. However, after 60 years of research, this efficiency saturated close to the the…
Detecting stellar-wind bubbles through infrared arcs in HII regions
Jonathan Mackey, Thomas J. Haworth, Vasilii V. Gvaramadze +3
Mid-infrared arcs of dust emission are often seen near ionizing stars within HII regions. A possible explanations for these arcs is that they could show the outer edges of asymmetr…
Simultaneous IRIS and Hinode/EIS observations and modelling of the 27 October 2014 X 2.0 class flare
V. Polito, J. W. Reep, K. K. Reeves +5
We present the study of the X2-class flare which occurred on the 27 October 2014 and was observed with the Interface Region Imaging Spectrograph (IRIS) and the EUV Imaging Spectrom…
Vibrational averages along thermal lines
Bartomeu Monserrat
A method is proposed for the calculation of vibrational quantum and thermal expectation values of physical properties from first principles. Thermal lines are introduced: these are…
Thermodynamics of Charged Black Holes in Einstein-Horndeski-Maxwell Theory
Xing-Hui Feng, Hai-Shan Liu, H. Lü +1
We extend an earlier investigation of the thermodynamics of static black holes in an Einstein-Horndeski theory of gravity coupled to a scalar field, by including now an elec- troma…
Drude in D major
Tomas Andrade, Simon A. Gentle, Benjamin Withers
We study holographic momentum relaxation in the limit of a large number of spacetime dimensions D. For an axion model we find that momentum conservation is restored as D becomes la…
Constraining the properties of neutron star crusts with the transient low-mass X-ray binary Aql X-1
A. C. Waterhouse, N. Degenaar, R. Wijnands +4
Aql X-1 is a prolific transient neutron star low-mass X-ray binary that exhibits an accretion outburst approximately once every year. Whether the thermal X-rays detected in interve…
An interplay of migratory and division forces as a generic mechanism for stem cell patterns
Edouard Hannezo, Alice Coucke, Jean-François Joanny
In many adult tissues, stem cells and differentiated cells are not homogeneously distributed : stem cells are arranged in periodic "niches", and differentiated cells are constantly…
Tracking Urban Activity Growth Globally with Big Location Data
Matthew Daggitt, Anastasios Noulas, Blake Shaw +1
In recent decades the world has experienced rates of urban growth unparalleled in any other period of history and this growth is shaping the environment in which an increasing prop…
A simple way to improve AGN feedback prescription in SPH simulations
Kastytis Zubovas, Martin A. Bourne, Sergei Nayakshin
AGN feedback is an important ingredient in galaxy evolution, however its treatment in numerical simulations is necessarily approximate, requiring subgrid prescriptions due to the d…
Dynamical Constraints on Outer Planets in Super-Earth Systems
Matthew J. Read, Mark C. Wyatt
This paper considers secular interactions within multi-planet systems. In particular we consider dynamical evolution of known planetary systems resulting from an additional hypothe…
The CHIANTI atomic database
Peter R. Young, Ken P. Dere, Enrico Landi +2
The CHIANTI atomic database was first released in 1996 and has had a huge impact on the analysis and modeling of emissions from astrophysical plasmas. The database has continued to…
Generalized circuit model for coupled plasmonic systems
Felix Benz, Bart de Nijs, Christos Tserkezis +6
We develop an analytic circuit model for coupled plasmonic dimers separated by small gaps that provides a complete account of the optical resonance wavelength. Using a suitable equ…
Gaia Benchmark stars and their twins in the Gaia-ESO Survey
Paula Jofre
The Gaia benchmark stars are stars with very precise stellar parameters that cover a wide range in the HR diagram at various metallicities. They are meant to be good representative…
The JCMT Gould Belt Survey: Understanding the influence of molecular outflows on Gould Belt clouds
E. Drabek-Maunder, J. Hatchell, J. V. Buckle +2
Using JCMT Gould Belt Survey data from CO J=3-2 isotopologues, we present a meta-analysis of the outflows and energetics of star-forming regions in several Gould Belt clouds. The m…
Disk Dispersal: Theoretical Understanding and Observational Constraints
U. Gorti, R. Liseau, Zs. Sandor +1
Protoplanetary disks dissipate rapidly after the central star forms, on time-scales comparable to those inferred for planet formation. In order to allow the formation of planets, d…
De Sitter from T-branes
Michele Cicoli, Fernando Quevedo, Roberto Valandro
Hidden sector D7-branes with non-zero gauge flux are a generic feature of type IIB compactifications. A non-vanishing Fayet-Iliopoulos term induced by non-zero gauge flux leads to…
Shepherding Tidal Debris with the Galactic Bar: The Ophiuchus Stream
Kohei Hattori, Denis Erkal, Jason L. Sanders
The dynamics of stellar streams in rotating barred potentials is explained for the first time. Naturally, neighbouring stream stars reach pericentre at slightly different times. In…
