Turnaround radius of galaxy clusters in N-body simulations
Giorgos Korkidis, Vasiliki Pavlidou, Konstantinos Tassis +3
We use N-body simulations to examine whether a characteristic turnaround radius, as predicted from the spherical collapse model in a Universe, can be meaningfully iden…
Localizing the -ray emitting region in the blazar TXS 2013+370
E. Traianou, T. P. Krichbaum, B. Boccardi +9
The -ray production mechanism and its localization in blazars are still a matter of debate. The main goal of this paper is to constrain the location of the high-energy emission…
Stress-transfer from polymer substrates to monolayer and few-layer graphenes
Ch. Androulidakis, D. Sourlantzis, E. N. Koukaras +2
In the present study the stress transfer mechanism in graphene-polymer systems under tension is examined experimentally using the technique of laser Raman microscopy. We discuss in…
Stabilizing effect of magnetic helicity on magnetic cavities in the intergalactic medium
Simon Candelaresi, Fabio Del Sordo
We investigate the effect of magnetic helicity on the stability of buoyant magnetic cavities as found in the intergalactic medium. In these cavities, we insert helical magnetic fie…
A Review on Intelligent Object Perception Methods Combining Knowledge-based Reasoning and Machine Learning
Filippos Gouidis, Alexandros Vassiliades, Theodore Patkos +3
Object perception is a fundamental sub-field of Computer Vision, covering a multitude of individual areas and having contributed high-impact results. While Machine Learning has bee…
Towards improving the e-learning experience for deaf students: e-LUX
Fabrizio Borgia, Claudia S. Bianchini, Maria de Marsico
Deaf people are more heavily affected by the digital divide than many would expect. Moreover, most accessibility guidelines addressing their needs just deal with captioning and aud…
The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet beta Pictoris b from Combined Direct Imaging and Astrometry
Eric L. Nielsen, Robert J. De Rosa, Jason J. Wang +51
We present new observations of the planet beta Pictoris b from 2018 with GPI, the first GPI observations following conjunction. Based on these new measurements, we perform a joint…
First Resolved Scattered-Light Images of Four Debris Disks in Scorpius-Centaurus with the Gemini Planet Imager
Justin Hom, Jennifer Patience, Thomas M. Esposito +57
We present the first spatially resolved scattered-light images of four debris disks around members of the Scorpius-Centaurus (Sco-Cen) OB Association with high-contrast imaging and…
Star-forming Clumps in Local Luminous Infrared Galaxies
K. L. Larson, T. Díaz-Santos, L. Armus +15
We present narrow-band near-infrared imaging of Pa and Pa emission of 48 local Luminous Infrared Galaxies (LIRGs) from the Great Observatories All-Sky LIRG Survey (GOAL…
Eliminating artefacts in Polarimetric Images using Deep Learning
Dhruv Paranjpye, Ashish Mahabal, A. N. Ramaprakash +5
Polarization measurements done using Imaging Polarimeters such as the Robotic Polarimeter are very sensitive to the presence of artefacts in images. Artefacts can range from intern…
The coin that never sleeps. The privacy preserving usage of Bitcoin in a longitudinal analysis as a speculative asset
Emmanouil Karampinakis, Michalis Pachilakis, Panagiotis Papadopoulos +2
Bitcoin is the first and undoubtedly most successful cryptocurrecny to date with a market capitalization of more than 100 billion dollars. Today, Bitcoin has more than 100,000 supp…
NELIOTA: Methods, statistics and results for meteoroids impacting the Moon
Alexios Liakos, Alceste Bonanos, Emmanouil Xilouris +8
This paper contains the results from the first 30 months of the NELIOTA project for impacts of NEOs/meteoroids on the lunar surface. Our analysis on the statistics concerning the e…
Probing fragmentation and velocity sub-structure in the massive NGC 6334 filament with ALMA
Y. Shimajiri, Ph. Andre, E. Ntormousi +3
Herschel surveys of Galactic clouds support a paradigm for low-mass star formation in which dense filaments play a crucial role. The detailed fragmentation properties of star-formi…
ELGAR -- a European Laboratory for Gravitation and Atom-interferometric Research
B. Canuel, S. Abend, P. Amaro-Seoane +55
Gravitational Waves (GWs) were observed for the first time in 2015, one century after Einstein predicted their existence. There is now growing interest to extend the detection band…
Scattering of spinon excitations by potentials in the 1D Heisenberg model
A. Pavlis, X. Zotos
By a semi-analytical Bethe ansatz method and a T-matrix approach we study the scattering of a spinon, the elementary quantum many-body topological excitation in the 1D Heisenberg m…
Modeling the magnetized Local Bubble from dust data
V. Pelgrims, K. Ferrière, F. Boulanger +2
The Sun is embedded in the so-called Local Bubble (LB) -- a cavity of hot plasma created by supernova explosions and surrounded by a shell of cold, dusty gas. Knowing the local dis…
Dressed excitations, thermodynamics and relaxation in the 1D XXZ Heisenberg model
A. Pavlis, X. Zotos
In this note, we discuss the low and high temperature contribution of Thermodynamic Bethe Ansatz (TBA) dressed excitations in the thermodynamics and energy-magnetization relaxation…
