Discovery of a new INTEGRAL source: IGR J19140+0951
D. C. Hannikainen, J. Rodriguez, C. Cabanac +5
IGR J19140+0951 (formerly known as IGR J19140+098) was discovered with the INTEGRAL satellite in March 2003. We report the details of the discovery, using an improved position for…
The nature of the infrared counterpart of IGR J19140+0951
D. C. Hannikainen, M. G. Rawlings, P. Muhli +3
The INTEGRAL observatory has been (re-)discovering new X-ray sources since the beginning of nominal operations in early 2003. These sources include X-ray binaries, Active Galactic…
Microscopic Observation of Non-Ergodic States in Two-Dimensional Non-Topological Bubble Lattices
S. Pylypenko, M. Winter, U. K. RöÃler +12
Disordered 2D lattices, including hexatic and various glassy states, are observed in a wide range of 2D systems including colloidal nanoparticle assemblies and fluxon lattices. The…
X-ray properties of 4U 1543-624
J. Schultz
4U 1543-624 is a relatively bright persistent low-mass X-ray binary. Analysis of archival data from ASCA, SAX and RXTE is presented. The X-ray continuum be can modeled with the sta…
BeppoSAX observations of the EXS 1737.9-2952 region II: Analysis of sources
J. Huovelin, J. Schultz, O. Vilhu +3
(Abridged) Spectral and time variability analysis of the region of the hard X-ray transient EXS 1737.9-2952 near the Galactic Centre (GC), using data from the Narrow Field Instrume…
In.XS: project for a future spaceborne hard X-ray all-sky survey
P. B. Marty, J. Schultz, C. Bayer +13
The latest all-sky survey in hard X-ray band was performed by the HEAO-1 satellite (13-80 keV) with an angular resolution of 24x48 arcmin. A diffuse hard X-Ray background (HXB) was…
Unveiling the Nature of the High Energy Source IGR J19140+0951
J. Rodriguez, C. Cabanac, D. C. Hannikainen +3
We report on high energy observations of IGR J19140+0951 performed with RXTE on three occasions in 2002, 2003 and 2004, and INTEGRAL during a very well sampled and unprecedented hi…
Spectral field mapping in plasmonic nanostructures with nanometer resolution
J. Krehl, G. Guzzinati, J. Schultz +7
Plasmonic nanostructures and devices are rapidly transforming light manipulation technology by allowing to modify and enhance optical fields on sub-wavelength scales. Advances in t…
Transport of Intensity Phase Retrieval in the Presence of Intensity Variations and Unknown Boundary Conditions
A. Lubk, R. Kyrychenko, D. Wolf +8
The so-called Transport of Intensity Equation (TIE) phase retrieval technique is widely applied in light, x-ray and electron optics to reconstruct, e.g., refractive indices, electr…
The Physics of the B Factories
A. J. Bevan, B. Golob, Th. Mannel +2003
This work is on the Physics of the B Factories. Part A of this book contains a brief description of the SLAC and KEK B Factories as well as their detectors, BaBar and Belle, and da…
Measurement of the branching ratios , and
M. Andreotti, S. Bagnasco, W. Baldini +46
We have measured several branching ratios for decay using the data collected by FNAL E835 experiment during year 2000, obtaining ${\cal B}(Ï^\prime \to e^+ e^-) = 0.00…
Optical and acoustic plasmons in the layered material SrRuO
J. Schultz, A. Lubk, F. Jerzembeck +5
We use momentum-dependent electron energy-loss spectroscopy in transmission to study collective charge excitations in the layer metal SrRuO. This metal has a transition fro…
JEM-X background models
J. Huovelin, S. Maisala, J. Schultz +4
Background and determination of its components for the JEM-X X-ray telescope on INTEGRAL are discussed. A part of the first background observations by JEM-X are analysed and result…
Precision measurements of the total and partial widths of the psi(2S) charmonium meson with a new complementary-scan technique in antiproton-proton annihilations
Fermilab E835 Collaboration, M. Andreotti, S. Bagnasco +46
We present new precision measurements of the psi(2S) total and partial widths from excitation curves obtained in antiproton-proton annihilations by Fermilab experiment E835 at the…
