H.E.S.S. reveals a lack of TeV emission from the supernova remnant Puppis A
H. E. S. S. Collaboration, :, A. Abramowski +224
Puppis A is an interesting ~4 kyr-old supernova remnant (SNR) that shows strong evidence of interaction between the forward shock and a molecular cloud. It has been studied in deta…
Diffuse Galactic gamma-ray emission with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +225
Diffuse -ray emission is the most prominent observable signature of celestial cosmic-ray interactions at high energies. While already being investigated at GeV energies over sev…
Long-term monitoring of PKS 2155304 with ATOM and H.E.S.S.: investigation of optical/-ray correlations in different spectral states
A. Abramowski, F. Aharonian, F. Ait Benkhali +225
In this paper we report on the analysis of all the available optical and very high-energy -ray (200 GeV) data for the BL Lac object PKS 2155304, collected simultaneously w…
The Degrees of Freedom of Partly Smooth Regularizers
Samuel Vaiter, Charles-Alban Deledalle, Jalal M. Fadili +2
In this paper, we are concerned with regularized regression problems where the prior regularizer is a proper lower semicontinuous and convex function which is also partly smooth re…
Fourier multipliers for weighted spaces with Lévy-Khinchin-Schoenberg weights
Nikolai K. Nikolski, Igor E. Verbitsky
We present a class of weight functions on the circle , called Lévy-Khinchin-Schoenberg (LKS) weights, for which we are able to completely characterize (in terms o…
Sets of unique continuation for heat equation
Nikolai Nadirashvili, Nadezda Varkentina
We study nodal lines of solutions to the heat equations. We are interested in the global geometry of nodal sets, in the whole domain of definition of the solution. The local struct…
Multi-particle emission in the decay of 31Ar
G. T. Koldste, B. Blank, M. J. G. Borge +20
A multi-hit capacity setup was used to study the decay of the dripline nucleus 31Ar, produced at the ISOLDE facility at CERN. A spectroscopic analysis of the beta-delayed three-pro…
HESS J1640-465 - an exceptionally luminous TeV gamma-ray supernova remnant
H. E. S. S. Collaboration, A. Abramowski, F. Aharonian +218
The results of follow-up observations of the TeV gamma-ray source HESSJ 1640-465 from 2004 to 2011 with the High Energy Stereoscopic System (H.E.S.S.) are reported in this work. Th…
Flux upper limits for 47 AGN observed with H.E.S.S. in 2004-2011
H. E. S. S. Collaboration, A. Abramowski, F. Aharonian +217
About 40% of the observation time of the High Energy Stereoscopic System (H.E.S.S.) is dedicated to studying active galactic nuclei (AGN), with the aim of increasing the sample of…
In-line extraction of an ultra-stable frequency signal over an optical fiber link
Anthony Bercy, Saïda Guellati-Khélifa, Fabio Stefani +5
We demonstrate in-line extraction of an ultra-stable frequency signal over an optical link of 92-km of installed telecommunication fibers, following the proposition of G. Grosche i…
Collective thermoelectrophoresis of charged colloids
Arghya Majee, Alois Würger
Thermally driven colloidal transport is, to a large extent, due to the thermoelectric or Seebeck effect of the charged solution.We show that, contrary to the generally adopted sing…
Thermocharge of a hot spot in an electrolyte solution
Arghya Majee, Alois Wüurger
We discuss the thermoelectric properties of a locally heated micron-size volume in an electrolyte solution. We find that such a hot spot carries a net charge Q which, for an excess…
Transport in Charged Colloids Driven by Thermoelectricity
Alois Würger
We study the thermal diffusion coefficient DT of a charged colloid in a temperature gradient, and find that it is to a large extent determined by the thermoelectric response of the…
Search for Extended γ-ray Emission around AGN with H.E.S.S. and Fermi-LAT
H. E. S. S. Collaboration, A. Abramowski, F. Aharonian +218
Context: Very-high-energy (VHE; E>100 GeV) γ-ray emission from blazars inevitably gives rise to electron-positron pair production through the interaction of these γ-rays with the E…
Experimental study of the two-body spin-orbit force
G. Burgunder, O. Sorlin, F. Nowacki +31
Energies and spectroscopic factors of the first , , and states in the Si nucleus were determined by means of the (d,p) transfer reaction…
Observation of the -delayed -proton decay of Zn and its impact on the Gamow Teller strength evaluation
S. E. A. Orrigo, B. Rubio, Y. Fujita +25
We report the observation of a very exotic decay mode at the proton drip-line, the -delayed -proton decay, clearly seen in the decay of the = -2 nucleus Zn.…
An efficient playout smoothing mechanism for layered streaming in P2P networks
Abbas Bradai, Ubaid Abbasi, Raul Landa +1
Layered video streaming in peer-to-peer (P2P) networks has drawn great interest, since it can not only accommodate large numbers of users, but also handle peer heterogeneity. Howev…
Two active states of the narrow-line gamma-ray-loud AGN GB 1310+487
K. V. Sokolovsky, F. K. Schinzel, Y. T. Tanaka +49
Previously unremarkable, the extragalactic radio source GB 1310+487 showed a gamma-ray flare on 2009 November 18, reaching a daily flux of ~10^-6 photons/cm^2/s at energies E>100 M…
