LArGe: Background suppression using liquid argon (LAr) scintillation for 0 decay search with enriched germanium (Ge) detectors
M. Di Marco, P. Peiffer, S. Schönert
Measurements with a bare p-type high purity germanium diode (HPGe) submerged in a 19 kg liquid argon (LAr) scintillation detector at MPIK Heidelberg are reported. The liquid argon-…
Two-Loop Bethe Logarithms for non-S Levels
U. D. Jentschura
Two-loop Bethe logarithms are calculated for excited P and D states in hydrogenlike systems, and estimates are presented for all states with higher angular momenta. These results c…
Forced oscillations in relativistic accretion disks and QPOs
J. Petri
In this work we explore the idea that the high frequency QPOs observed in LMXBs may be explained as a resonant coupling between the neutron star spin and epicyclic modes of accreti…
Hemispherical transport equation: modeling of quasiparallel collisionless shocks
V. N. Zirakashvili
Using a so-called hemispherical model we derive a general transport equation for cosmic ray and thermal particles scattered in pitch angle by magnetic inhomogeneities in a moving c…
A low density of the Extragalactic Background Light revealed by the H.E.S.S. spectra of the BLLac objects 1ES 1101-232 and H 2356-309
L. Costamante
The unexpectedly hard spectra measured by HESS for the BLLacs 1ES 1101-232 and H 2356-309 has allowed an upper limit on the Extragalactic Background Light (EBL) to be derived in th…
H.E.S.S. observations of the supernova remnant RX J0852.0-4622: shell-type morphology and spectrum of a widely extended VHE gamma-ray source
HESS Collaboration, F. A. Aharonian
The shell-type supernova remnant RX J0852.0-4622 was observed with the High Energy Stereoscopic System (H.E.S.S.) of Atmospheric Cherenkov Telescopes between December 2004 and May…
Storage-ring measurement of the hyperfine induced 47Ti18+(2s 2p 3P0 -> 2s2 1S0) transition rate
S. Schippers, E. W. Schmidt, D. Bernhardt +7
The hyperfine induced 2s 2p 3P0 > 2s2 1S0 transition rate AHFI in berylliumlike 47Ti18+ was measured. Resonant electron-ion recombination in a heavy-ion storage ring was employed t…
Theoretical overview on high-energy emission in microquasars
V. Bosch-Ramon
Microquasar (MQ) jets are sites of particle acceleration and synchrotron emission. Such synchrotron radiation has been detected coming from jet regions of different spatial scales,…
Bottom production cross section from double muonic decays of b-hadrons in 920 GeV proton-nucleus collision
B Collaboration, I. Abt
The b-bbar production cross section in 920 GeV proton-nucleus fixed target collisions is measured by observing double muonic decays of b-flavored hadrons in the kinematic region $-…
Corrections to Tri-bimaximal Neutrino Mixing: Renormalization and Planck Scale Effects
Amol Dighe, Srubabati Goswami, Werner Rodejohann
We study corrections to tri-bimaximal (TBM) neutrino mixing from renormalization group (RG) running and from Planck scale effects. We show that while the RG effects are negligible…
Analytical solutions for energy spectra of electrons accelerated by nonrelativistic shock-waves in shell type supernova remnants
V. N. Zirakashvili, F. Aharonian
%context {Recent observations of hard X-rays and very high energy gamma-rays from a number of young shell type supernova remnants indicate the importance of detailed quantitative s…
Fast variability of TeV gamma-rays from the radio galaxy M 87
HESS Collaboration, F. A. Aharonian
The detection of fast variations of the TeV (10^12 eV) gamma-ray flux, on time-scales of days, from the nearby radio galaxy M 87 is reported. These variations are ~10 times faster…
Remnants of compact binary mergers
W. Domainko, M. Ruffert
We investigate the long-term evolution and observability of remnants originating from the merger of compact binary systems and discuss the differences to supernova remnants. Compac…
The diocotron instability in a pulsar cylindrical electrosphere
J. Petri
The physics of the pulsar inner magnetosphere remains poorly constrained by observations. Although about 2000 pulsars have been discovered to date, little is known about their emis…
The population of radio sources in the field of the unidentified gamma-ray source TeV J2032+4130
Josep M. Paredes, Josep Marti, Ishwara Chandra C. H. +1
TeV J2032+4130 is the first extended very high energy gamma-ray source, which has remained enigmatic since its discovery, due to the lack of identification. We report here deep rad…
Two-loop QED corrections in few-electron ions
V. A. Yerokhin, P. Indelicato, V. M. Shabaev
Results of a calculation valid to all orders in the nuclear-strength parameter Zαare presented for the two-loop Lamb shift, notably for the two-loop self-energy correction, for the…

We present deep H.E.S.S. observations of the supernova remnant (SNR) RX J1713.7-3946. Combining data of three years - from 2003 to 2005 - we obtain significantly increased statisti…
On Symmetric Lepton Mixing Matrices
Kathrin A. Hochmuth, Werner Rodejohann
Contrary to the quark mixing matrix, the lepton mixing matrix could be symmetric. We study the phenomenological consequences of this possibility. In particular, we find that symmet…
