The Star Formation Reference Survey. II. Activity demographics and host-galaxy properties for Infrared-selected galaxies
A. Maragkoudakis, A. Zezas, M. L. N. Ashby +1
We present activity demographics and host-galaxy properties of infrared-selected galaxies in the local Universe, using the representative Star Formation Reference Survey (SFRS). Ou…
Crystal-to-crystal transition of ultrasoft colloids under shear
J. Ruiz-Franco, J. Marakis, N. Gnan +5
Ultrasoft colloids typically do not spontaneously crystallize, but rather vitrify, at high concentrations. Combining in-situ rheo-SANS experiments and numerical simulations we show…
The Deterministic and Stochastic Shallow Lake Problem
George T. Kossioris, Michail Loulakis, Panagiotis E. Souganidis
We study the welfare function of the deterministic and stochastic shallow lake problem. We show that the welfare function is the viscosity solution of the associated Bellman equati…
Chandra X-ray Constraints on the Candidate Ca-rich Gap Transient SN 2016hnk
P. H. Sell, K. Arur, T. J. Maccarone +4
We present a Chandra observation of SN 2016hnk, a candidate Ca-rich gap transient. This observation was specifically designed to test whether or not this transient was the result o…
Atomistic potential for graphene and other sp carbon systems
Zacharias G. Fthenakis, George Kalosakas, Georgios D. Chatzidakis +3
We introduce a torsional force field for sp carbon to augment an in-plane atomistic potential of a previous work (Kalosakas et al, J. Appl. Phys. {\bf 113}, 134307 (2013)) so t…
Scale invariant jets: from blazars to microquasars
I. Liodakis, V. Pavlidou, I. Papadakis +9
Black holes, anywhere in the stellar-mass to supermassive range, are often associated with relativistic jets. Models suggest that jet production may be a universal process common i…
Extragalactic Gamma-ray Background from Star-forming Galaxies: Will Empirical Scalings Suffice?
I. Komis, V. Pavlidou, A. Zezas
Despite the influx of unprecedented-quality data from the Fermi Gamma-Ray Space Telescope that have been collected over nine years of operation, the contribution of normal star-for…
On the high energy cut-off of accreting sources: is GR relevant?
Francesco Tamborra, Iossif Papadakis, Michal Dovčiak +1
The hard X-ray emission observed in accreting compact sources is believed to be produced by inverse Compton scattering of soft photons arising from the accretion disc by energetic…
On the Spatially Resolved Star-Formation History in M51 II: X-ray Binary Population Evolution
B. D. Lehmer, R. T Eufrasio, L. Markwardt +7
We present a new technique for empirically calibrating how the X-ray luminosity function (XLF) of X-ray binary (XRB) populations evolves following a star-formation event. We first…
RoboPol: Connection between optical polarization plane rotations and gamma-ray flares in blazars
D. Blinov, V. Pavlidou, I. Papadakis +21
We use results of our 3 year polarimetric monitoring program to investigate the previously suggested connection between rotations of the polarization plane in the optical emission…
Effect of Chain Stiffness on the Structure of Single-Chain Polymer Nanoparticles
Angel J. Moreno, Petra Bacova, Federica Lo Verso +3
Polymeric single-chain nanoparticles (SCNPs) are soft nano-objects synthesized by purely intramolecular cross-linking of single polymer chains. By means of computer simulations, we…
Connecting traces of galaxy evolution: the missing core mass -- morphological fine structure relation
P. Bonfini, T. Bitsakis, A. Zezas +5
Deep exposure imaging of early-type galaxies (ETGs) are revealing the second-order complexity of these objects, which have been long considered uniform, dispersion-supported sphero…
The photon-index - time-lag correlation in black-hole X-ray binaries
Pablo Reig, Nikolaos D. Kylafis, Iossif E. Papadakis +1
We have performed a timing and spectral analysis of a set of black-hole binaries to study the correlation between the photon index and the time lag of the hard photons with respect…
Wide Binaries in Tycho-Gaia II: Metallicities, Abundances, and Prospects for Chemical Tagging
Jeff J. Andrews, Julio Chanamé, Marcel A. Agüeros
From our recent catalog based on the first Gaia data release (TGAS), we select wide binaries in which both stars have been observed by the Radial Velocity Experiment (RAVE) or the…
dart_board: Binary Population Synthesis with Markov Chain Monte Carlo
Jeff J Andrews, Andreas Zezas, Tassos Fragos
By employing Monte Carlo random sampling, traditional binary population synthesis (BPS) offers a substantial improvement in efficiency over brute force, grid-based studies. Even so…
Temperature dependence of the coherence in polariton condensates
E. Rozas, M. D. Martín, C. Tejedor +4
We present a time-resolved experimental study of the temperature effect on the coherence of traveling polariton condensates. The simultaneous detection of their emission both in re…
Optical bistability under non-resonant excitation in spinor polariton condensates
L. Pickup, K. Kalinin, A. Askitopoulos +4
We realise bistability in the spinor of polariton condensates under non-resonant optical excitation and in the absence of biasing external fields. Numerical modelling of the system…
Dynamics on the Double Morse Potential: A Paradigm for Roaming Reactions with no Saddle Points
Barry K. Carpenter, Gregory S. Ezra, Stavros C. Farantos +2
In this paper we analyze a two degree of freedom Hamiltonian system constructed from two planar Morse potentials. The resulting potential energy surface has two potential wells sur…
Long-term optical and X-ray variability of the Be/X-ray binary H 1145-619: discovery of an on-going retrograde density wave
J. Alfonso-Garzón, J. Fabregat, P. Reig +7
Multiwavelength monitoring of Be/X-ray binaries is crucial to understand the mechanisms producing their outbursts. H 1145-619 is one of these systems, which has recently displayed…
The nature of X-ray spectral variability in MCG-6-30-15
E. S. Kammoun, I. E. Papadakis
The flux-flux plot (FFP) method can provide model-independent clues regarding the X-ray variability of active galactic nuclei. To use it properly, the bin size of the light curves…
Optical EVPA rotations in blazars: testing a stochastic variability model with RoboPol data
S. Kiehlmann, D. Blinov, T. J. Pearson +1
We identify rotations of the polarization angle in a sample of blazars observed for three seasons with the RoboPol instrument. A simplistic stochastic variability model is tested a…
