Probing the accelerating Universe with radio weak lensing in the JVLA Sky Survey
M. L. Brown, F. B. Abdalla, A. Amara +48
We outline the prospects for performing pioneering radio weak gravitational lensing analyses using observations from a potential forthcoming JVLA Sky Survey program. A large-scale…
A new CVD Diamond Mosaic-Detector for (n,) Cross-Section Measurements at the n\_TOF Experiment at CERN
C. Weiss, E. Griesmayer, C. Guerrero +1
At the n\_TOF experiment at CERN a dedicated single-crystal chemical vapor deposition (sCVD) Diamond Mosaic-Detector has been developed for (n,) cross-section measurements. The…
Foreground contamination in Ly-alpha intensity mapping during the epoch of reionization
Yan Gong, Marta Silva, Asantha Cooray +1
The intensity mapping of Ly-alpha emission during the epoch of reionization (EoR) will be contaminated by foreground emission lines from lower redshifts. We calculate the mean inte…
Nonlinear Acoustics -- Perturbation Theory and Webster's Equation
Rogério Jorge
Webster's horn equation (1919) offers a one-dimensional approximation for low-frequency sound waves along a rigid tube with a variable cross-sectional area. It can be thought as a…
Electron and Ion Heating during Magnetic Reconnection in Weakly Collisional Plasmas
Ryusuke Numata, Nuno F. Loureiro
Gyrokinetic simulations of magnetic reconnection are presented to investigate plasma heating for strongly magnetized, weakly collisional plasmas. For a low plasma beta case, parall…
On Logical Depth and the Running Time of Shortest Programs
L. Antunes, A. Souto, P. M. B. Vitanyi
The logical depth with significance of a finite binary string is the shortest running time of a binary program for that can be compressed by at most bits. There is…
Transverse target spin asymmetries in exclusive muoproduction
C. Adolph, M. G. Alekseev, V. Yu. Alexakhin +209
Exclusive production of mesons was studied at the COMPASS experiment by scattering 160 GeV/ muons off transversely polarised protons. Five single-spin and three double-spi…
Identifying Clouds over the Pierre Auger Observatory using Infrared Satellite Data
Pierre Auger Collaboration
We describe a new method of identifying night-time clouds over the Pierre Auger Observatory using infrared data from the Imager instruments on the GOES-12 and GOES-13 satellites. W…
Coalescence of binary neutron stars in a scalar-tensor theory of gravity
Masaru Shibata, Keisuke Taniguchi, Hirotada Okawa +1
We carry out numerical-relativity simulations of coalescing binary neutron stars in a scalar-tensor theory that admits spontaneous scalarization. We model neutron stars with realis…
Witten's loop in the flipped SU(5) unification
Michal Malinský, Carolina Arbeláez Rodríguez, Helena Kolešová
We study a very simple, yet potentially realistic renormalizable flipped SU(5) scenario in which the right-handed neutrino masses are generated at very high energies by means of a…
Possible Anderson localization in a holographic superconductor
Hua Bi Zeng
We study the effect of disorder in a holographic superconductor by introducing a quasi-periodic chemical potential. When the condensation of the superconductor is sufficiently smal…
Solar neutrino physics: Sensitivity to light dark matter particles
Ilidio Lopes, Joseph Silk
Neutrinos are produced in several neutrino nuclear reactions of the proton-proton chain and carbon-nitrogen-oxygen cycle that take place at different radius of the Sun's core. Henc…
The spherically symmetric Einstein-scalar field system with positive and vanishing cosmological constant: a comparison
João L. Costa
We review recent results concerning the spherically symmetric Einstein-scalar field system with positive cosmological constant. We do so by comparing with the classical results of…
Fabrication and Response of High Concentration SIMPLE Superheated Droplet Detectors with Different Liquids
M. Felizardo, T. Morlat, J. G. Marques +7
The combined measurement of dark matter interactions with different superheated liquids has recently been suggested as a cross-correlation technique in identifying WIMP candidates.…
Products of 2X2 matrices related to non autonomous Fibonacci difference equations
Rafael Luís, Henrique Oliveira
A technique to compute arbitrary products of a class of Fibonacci square matrices is proved in this work. General explicit solutions for non autonomous Fibonacci differe…
Black holes with massive graviton hair
Richard Brito, Vitor Cardoso, Paolo Pani
No-hair theorems exclude the existence of nontrivial scalar and massive vector hair outside four-dimensional, static, asymptotically flat black-hole spacetimes. We show, by explici…
Witten's mechanism in the flipped SU(5) unification
Carolina Arbeláez, Helena Kolešová, Michal Malinský
We argue that the Witten's loop mechanism for the right-handed Majorana neutrino mass generation identified originally in the SO(10) grand unification context can be successfully a…
Black hole bombs and explosions: from astrophysics to particle physics
Vitor Cardoso
Black holes are the elementary particles of gravity, the final state of sufficiently massive stars and of energetic collisions. With a forty-year long history, black hole physics i…
Constraining Primordial Black-Hole Bombs through Spectral Distortions of the Cosmic Microwave Background
Paolo Pani, Abraham Loeb
We consider the imprint of superradiant instabilities of nonevaporating primordial black holes (PBHs) on the spectrum of the cosmic microwave background (CMB). In the radiation dom…
Initial Conditions for Numerical Relativity -- Introduction to numerical methods for solving elliptic PDEs
Hirotada Okawa
Numerical relativity became a powerful tool to investigate the dynamics of binary problems with black holes or neutron stars as well as the very structure of General Relativity. Al…
Numerical modelling of Ar glow discharge at intermediate and high pressures
George M. Petrov, Carlos M. Ferreira
A detailed collisional-radiative model for Ar at intermediate and high pressures is developed. The model is coupled with the electron Boltzmann equation and includes several highly…
Convergence Rates of Distributed Nesterov-like Gradient Methods on Random Networks
Dusan Jakovetic, Joao Xavier, Jose M. F. Moura
We consider distributed optimization in random networks where N nodes cooperatively minimize the sum \sum_{i=1}^N f_i(x) of their individual convex costs. Existing literature propo…
Black holes with surrounding matter in scalar-tensor theories
Vitor Cardoso, Isabella P. Carucci, Paolo Pani +1
We uncover two mechanisms that can render Kerr black holes unstable in scalar-tensor gravity, both associated to the presence of matter in the vicinity of the black hole and the fa…
A thermal quench induces spatial inhomogeneities in a holographic superconductor
Antonio M. García-García, Hua Bi Zeng, Hai Qing Zhang
Holographic duality is a powerful tool to investigate the far-from equilibrium dynamics of superfluids and other phases of quantum matter. For technical reasons it is usually assum…
