Accretion and ejection in black-hole X-ray transients
N. D. Kylafis, T. M. Belloni
Aims: We summarize the current observational picture of the outbursts of black-hole X-ray transients (BHTs), based on the evolution traced in a hardness-luminosity diagram (HLD), a…
Parametric Sensitivity Analysis for Stochastic Molecular Systems using Information Theoretic Metrics
Anastasios Tsourtis, Yannis Pantazis, Markos A. Katsoulakis +1
In this paper we extend the parametric sensitivity analysis (SA) methodology proposed in Ref. [Y. Pantazis and M. A. Katsoulakis, J. Chem. Phys. 138, 054115 (2013)] to continuous t…
Design of a dual species atom interferometer for space
Thilo Schuldt, Christian Schubert, Markus Krutzik +54
Atom interferometers have a multitude of proposed applications in space including precise measurements of the Earth's gravitational field, in navigation & ranging, and in fundament…
Towards Defeating the Crossfire Attack using SDN
Dimitrios Gkounis, Vasileios Kotronis, Xenofontas Dimitropoulos
In this work, we propose online traffic engineering as a novel approach to detect and mitigate an emerging class of stealthy Denial of Service (DoS) link-flooding attacks. Our appr…
Ferroelectricity in underdoped La-based cuprates
Z. Viskadourakis, S. S. Sunku, S. Mukherjee +4
Doping a parent antiferromagnetic Mott insulator in cuprates leads to short-range electronic correlations and eventually to high-Tc superconductivity. However, the nature of charge…
Testing Lambda CDM cosmology at turnaround: where to look for violations of the bound?
Dimitrios Tanoglidis, Vasiliki Pavlidou, Theodore Tomaras
In CDM cosmology, structure formation is halted shortly after dark energy dominates the mass/energy budget of the Universe. A manifestation of this effect is that in such a cosm…
Hysteresis and metastability of Bose-Einstein condensed clouds of atoms confined in ring potentials
A. Roussou, G. D. Tsibidis, J. Smyrnakis +4
We consider a Bose-Einstein condensed cloud of atoms which rotate in a toroidal/annular potential. Assuming one-dimensional motion, we evaluate the critical frequencies associated…
Population statistics of beamed sources. II: Evaluation of Doppler factor estimates
I. Liodakis, V. Pavlidou
In a companion paper we presented a statistical model for the blazar population, consisting of distributions for the unbeamed radio luminosity function and the Lorentz factor distr…
Population statistics of beamed sources. I: A new model for blazars
I. Liodakis, V. Pavlidou
Observations of blazar jets are shrouded in relativistic effects, thus hindering our understanding of their intrinsic properties and dominant physical processes responsible for the…
Long-term variability of high-mass X-ray binaries. I.Photometry
P. Reig, J. Fabregat
We present photometric observations of the field around the optical counterparts of high-mass X-ray binaries. Our aim is to study the long-term photometric variability in correlati…
Ultrafast Probes of Nonequilibrium Hole Spin Relaxation in Ferromagnetic Semiconductor GaMnAs
Aaron Patz, Tianqi Li, Xinyu Liu +3
We directly measure the hole spin lifetime in ferromagnetic GaMnAs via time- and polarization-resolved spectroscopy. Below the Curie temperature Tc, an ultrafast photoexcitation wi…
Manipulating Femtosecond Spin--Orbit Torques with Laser Pulse Sequences to Control Magnetic Memory States and Ringing
P. C. Lingos, J. Wang, I. E. Perakis
Femtosecond (fs) coherent control of collective order parameters is important for non--equilibrium phase dynamics in correlated materials. Here we propose a possible scheme for fs…
The connection between the 15 GHz radio and gamma-ray emission in blazars
W. Max-Moerbeck, J. L. Richards, T. Hovatta +5
Since mid-2007 we have carried out a dedicated long-term monitoring programme at 15 GHz using the Owens Valley Radio Observatory 40 meter telescope. One of the main goals of this p…
Robust platform for engineering pure-quantum-state transitions in polariton condensates
A. Askitopoulos, T. C. H. Liew, H. Ohadi +3
We report on pure-quantum-state polariton condensates in optical annular traps. The study of the underlying mechanism reveals that the polariton wavefunction always coalesces in a…
CARMA Large Area Star Formation Survey: Structure and Kinematics of Dense Gas in Serpens Main
Katherine I. Lee, Manuel Fernandez-Lopez, Shaye Storm +21
We present observations of N2H+(1-0), HCO+(1-0), and HCN(1-0) toward the Serpens Main molecular cloud from the CARMA Large Area Star Formation Survey (CLASSy). We mapped 150 square…
The high optical polarization in the Be/X-ray binary EXO 2030+375
P. Reig, D. Blinov, I. Papadakis +2
Polarization in classical Be stars results from Thomson scattering of the unpolarized light from the Be star in the circumstellar disc. Theory and observations agree that the maxim…
Spectral energy distributions of the BL Lac PKS 2155-304 from XMM-Newton
Jai Bhagwan, Alok C. Gupta, I. E. Papadakis +1
We have used all 20 archival XMM-Newton observations of PKS 2155-304 with simultaneous X-ray and UV/optical data to study its long term flux and spectral variability. We find signi…
Early-time polarized optical light curve of GRB 131030A
O. G. King, D. Blinov, D. Giannios +23
We report the polarized optical light curve of a gamma-ray burst afterglow obtained using the RoboPol instrument. Observations began 655 seconds after the initial burst of gamma-ra…
The quiescent state of the accreting X-ray pulsar SAX J2103.5+4545
P. Reig, V. Doroshenko, A. Zezas
We present an X-ray timing and spectral analysis of the Be/X-ray binary SAX J2103.5+4545 at a time when the Be star's circumstellar disk had disappeared and thus the main reservoir…
