A detailed spectral and morphological study of the gamma-ray supernova remnant RX J1713.7-3946 with H.E.S.S
The HESS Collaboration, F. Aharonian
We present results from deep observations of the Galactic shell-type supernova remnant (SNR) RX J1713.7-3946 (also known as G347.3-0.5) conducted with the complete H.E.S.S. array i…
[OIII] profile substructure in radio-quiet quasars
Christian Leipski, Nicola Bennert
Interactions between the radio jet and the optical emission of the narrow-line region (NLR) are a well known phenomenon in Seyfert galaxies. Here, we present the study of possible…
Size and Properties of the NLR in the Seyfert-2 Galaxy NGC 1386
Nicola Bennert, Bruno Jungwiert, Stefanie Komossa +2
We study the narrow-line region (NLR) of the Seyfert-2 galaxy NGC 1386 by means of long-slit spectroscopy obtained with FORS1 at the VLT. We use the galaxy itself for subtracting t…
Non-thermal high-energy emission from colliding winds of massive stars
A. Reimer, M. Pohl, O. Reimer
Colliding winds of massive star binary systems are considered as potential sites of non-thermal high-energy photon production. This is motivated merely by the detection of synchrot…
Quantum electrodynamical shocks and solitons in astrophysical plasmas
M. Marklund, D. D. Tskhakaya, P. K. Shukla
The nonlinear propagation of low-frequency circularly polarized waves in a magnetized dusty plasma is analyzed. It is found that wave steepening and shock formation can take place…
The H.E.S.S. survey of the Inner Galaxy in very high-energy gamma-rays
The HESS Collaboration, F. Aharonian
We report on a survey of the inner part of the Galactic Plane in very high energy gamma-rays, with the H.E.S.S. Cherenkov telescope system. The Galactic Plane between +-30deg in lo…
A possible association of the new VHE gamma-ray source HESS J1825--137 with the pulsar wind nebula G18.0--0.7
HESS Collaboration, F. A. Aharonian
We report on a possible association of the recently discovered very high-energy -ray source HESS J1825--137 with the pulsar wind nebula (commonly referred to as G 18.0--0.7) of…
Large-scale magnetized outflows from the Virgo Cluster spiral NGC4569
K. T. Chyzy, M. Soida, D. J. Bomans +3
Using the Effelsberg radio telescope at 4.85GHz and 8.35 GHz we discovered large symmetric lobes of polarized radio emission around the strongly HI deficient Virgo cluster spiral g…
The multi-phase gaseous halos of star forming late-type galaxies - I. XMM-Newton observations of the Hot Ionized Medium
R. Tuellmann, W. Pietsch, J. Rossa +2
This study presents first results from an X-ray mini-survey carried out with XMM-Newton to investigate the diffuse Hot Ionized Medium in the halos of nine nearby star-forming edge-…
Forms of Eulerian correlation functions in the solar wind
A. Shalchi
Current spacecraft missions such as Wind and ACE can be used to determine magnetic correlation functions in the solar wind. Data sets from these missions can, in principle, also be…
Spitzer IRS spectroscopy of 3CR radio galaxies and quasars: Testing the unified schemes
Martin Haas, Ralf Siebenmorgen, Bernhard Schulz +2
With the Spitzer Space Telescope Infrared Spectrograph (IRS) we have observed seven powerful FR2 radio galaxies and seven quasars. Both samples, the galaxies and the quasars, are c…
MAMBO 1.25mm observations of 3CR radio galaxies and quasars at z=1.5: On the debate of the unified schemes
Martin Haas, Rolf Chini, Sven Mueller +2
In order to explore the nature of the 850 micron flux difference between powerful radio galaxies and steep radio-spectrum quasars at z=1.5 reported by Willott et al. (2002), we hav…
GaBoDS: The Garching-Bonn Deep Survey V. Data release of the ESO Deep-Public-Survey
H. Hildebrandt, T. Erben, J. P. Dietrich +8
Aims. In this paper the optical data of the ESO Deep-Public-Survey observed with the Wide Field Imager and reduced with the THELI pipeline are described. Methods. Here we present 6…
Sub-arcsecond imaging of the radio continuum and neutral hydrogen in the Medusa merger
R. J. Beswick, S. Aalto, A. Pedlar +1
We present sub-arcsecond, Multi-Element Radio Linked Interferometer (MERLIN) observations of the decimetre radio continuum structure and neutral hydrogen (HI) absorption from the n…
A low level of extragalactic background light as revealed by gamma-rays from blazars
H. E. S. S. Collaboration, :, F. Aharonian
The diffuse extragalactic background light consists of the sum of the starlight emitted by galaxies through the history of the Universe, and it could also have an important contrib…
Systematic and quantitative approach for the identification of high energy gamma-ray source populations
Diego F. Torres, Olaf Reimer
A large fraction of the detections to be made by the Gamma-ray Large Area Space Telescope (GLAST) will initially be unidentified. We argue that traditional methodological approache…
A search for very high energy gamma-ray emission from the starburst galaxy NGC 253 with H.E.S.S
F. Aharonian et al.
We present the result of 28 hours of observations of the nearby starburst galaxy NGC 253 with the H.E.S.S. detector in 2003. We find no evidence for very high energy gamma-ray emis…
The ISO-2MASS AGN survey: On the type-1 sources
C. Leipski, M. Haas, H. Meusinger +9
We combined the ISOCAM Parallel Mode Survey at 6.7 micron (LW2 filter) with the Two Micron All Sky Survey in order to obtain a powerful tool to search for AGN independent of dust e…
