Stellar-mass black holes in young massive and open stellar clusters and their role in gravitational-wave generation
Sambaran Banerjee
The dynamical processes involving stellar-remnant black holes (BH) in stellar clusters has always drawn attention due to the BHs' potential in a number of astrophysical phenomena,…
Oscillation and suppression of Kondo temperature by RKKY coupling in two-site Kondo systems
Ammar Nejati, Johann Kroha
We apply our recently developed, selfconsistent renormalization group (RG) method to STM spectra of a two-impurity Kondo system consisting of two cobalt atoms connected by a one-di…
A chiral covariant approach to scattering
D. Gülmez, U. -G. Meißner, J. A. Oller
We analyze vector meson - vector meson scattering in a unitarized chiral theory based on a chiral covariant framework. We show that a pole assigned to the the scalar meson $f_0(137…
Properties of magnetars mimicking 56Ni-powered light curves in Type Ic superluminous supernovae
Takashi J. Moriya, Ting-Wan Chen, Norbert Langer
Many Type Ic superluminous supernovae have light-curve decline rates after their luminosity peak which are close to the nuclear decay rate of 56Co, consistent with the interpretati…
Hard Two-Photon Contribution to Elastic Lepton-Proton Scattering: Determined by the OLYMPUS Experiment
B. S. Henderson, L. D. Ice, D. Khaneft +67
The OLYMPUS collaboration reports on a precision measurement of the positron-proton to electron-proton elastic cross section ratio, , a direct measure of the contribution o…
First test of Verlinde's theory of Emergent Gravity using Weak Gravitational Lensing measurements
Margot M. Brouwer, Manus R. Visser, Andrej Dvornik +19
Verlinde (2016) proposed that the observed excess gravity in galaxies and clusters is the consequence of Emergent Gravity (EG). In this theory the standard gravitational laws are m…
The relation between globular cluster systems and supermassive black holes in spiral galaxies. The case study of NGC 4258
Rosa A. González-Lópezlira, Luis Lomelí-Núñez, Karla Álamo-Martínez +7
We aim to explore the relationship between globular cluster total number, , and central black hole mass, , in spiral galaxies, and compare it with that recen…
Galaxy-Galaxy Lensing in EAGLE: comparison with data from 180 square degrees of the KiDS and GAMA surveys
Marco Velliscig, Marcello Cacciato, Henk Hoekstra +14
We present predictions for the galaxy-galaxy lensing profile from the EAGLE hydrodynamical cosmological simulation at redshift z=0.18, in the spatial range 0.02 < R/(Mpc/h) < 2, an…
Imprints of the ejecta-companion interaction in Type Ia supernovae: main sequence, subgiant, and red giant companions
P. Boehner, T. Plewa, N. Langer
We study supernova ejecta-companion interactions in a sample of realistic semidetached binary systems representative of Type Ia supernova progenitor binaries in a single-degenerate…
Measuring entropy and mutual information in the two-dimensional Hubbard model
E. Cocchi, L. A. Miller, J. H. Drewes +4
We measure pressure and entropy of ultracold fermionic atoms in an optical lattice for a range of interaction strengths, temperatures and fillings. Our measurements demonstrate tha…
Detecting topological invariants in chiral symmetric insulators via losses
Tibor Rakovszky, Janos K. Asboth, Andrea Alberti
We show that the bulk winding number characterizing one-dimensional topological insulators with chiral symmetry can be detected from the displacement of a single particle, observed…
A New Model of Roche-lobe Overflow for Short-Period Gaseous Planets and Binary Stars
Brian Jackson, Phil Arras, Kaloyan Penev +2
Some close-in gaseous exoplanets are nearly in Roche-lobe contact, and previous studies show tidal decay can drive hot Jupiters into contact during the main sequence of their host…
IRAS 18153-1651: an H II region with a possible wind bubble blown by a young main-sequence B star
V. V. Gvaramadze, J. Mackey, A. Y. Kniazev +5
We report the results of spectroscopic observations and numerical modelling of the H II region IRAS 18153-1651. Our study was motivated by the discovery of an optical arc and two m…
New constraints on the 3-3-1 model with right-handed neutrinos
B. L. Sánchez-Vega, E. R. Schmitz, J. C. Montero
In the framework of a 3-3-1 model with right-handed neutrinos and three scalar triplets we consider different spontaneous symmetry breaking patterns seeking for a non-linear realiz…
On exotic equivalences and a theorem of Franke
Irakli Patchkoria
Using Franke's methods we construct new examples of exotic equivalences. We show that for any symmetric ring spectrum whose graded homotopy ring is concentrated in dimen…
Matrix product ansatz for non-equilibrium quantum steady states
D. Karevski, V. Popkov, G. M. Schütz
We present a general construction of matrix product states for stationary density matrices of one-dimensional quantum spin systems kept out of equilibrium through boundary Lindblad…
Characterization of Fully Depleted CMOS Active Pixel Sensors on High Resistivity Substrates for Use in a High Radiation Environment
Toko Hirono, Marlon Barbero, Patrick Breugnon +12
Depleted CMOS active sensors (DMAPS) are being developed for high-energy particle physics experiments in high radiation environments, such as in the ATLAS High Luminosity Large Had…
Characterization of the inner disk around HD 141569 A from Keck/NIRC2 L-band vortex coronagraphy
Dimitri Mawet, Élodie Choquet, Olivier Absil +22
HD 141569 A is a pre-main sequence B9.5 Ve star surrounded by a prominent and complex circumstellar disk, likely still in a transition stage from protoplanetary to debris disk phas…
Randomness via infinite computation and effective descriptive set theory
Merlin Carl, Philipp Schlicht
We study randomness beyond -randomness and its Martin-Löf type variant, introduced in \cite{MR2340241} and further studied in \cite{Continuous-higher-randomness}. The class…
Light-curve and spectral properties of ultra-stripped core-collapse supernovae leading to binary neutron stars
Takashi J. Moriya, Paolo A. Mazzali, Nozomu Tominaga +7
We investigate light-curve and spectral properties of ultra-stripped core-collapse supernovae. Ultra-stripped supernovae are the explosions of heavily stripped massive stars which…
