Magnetic fields and gas in the cluster-influenced spiral galaxy NGC 4254. II. Structures of magnetic fields
Chyży, K. T.
Aims: The origin of asymmetric radio polarized emission in the Virgo Cluster spiral NGC 4254 is investigated and the influence of cluster environment on the properties of magnetic fields is explored.
Methods: Structures of magnetic fields are analyzed with the concept of “magnetic maps”, presenting distributions of different magnetic field com…
Hard X-ray emission from η Carinae
Walter, R.; Rauw, G.; Leyder, J. -C.
Context: If relativistic particle acceleration takes place in colliding-wind binaries, hard X-rays and γ-rays are expected through inverse Compton emission, but to date these have never been unambiguously detected.
Aims: To detect this emission, observations of
A new view of quiet-Sun topology from Hinode/SOT
Régnier, S.; Parnell, C. E.; Haynes, A. L.
Context: With the recent launch of the Hinode satellite our view of the nature and evolution of quiet-Sun regions has been improved. In light of the new high resolution observations, we revisit the study of the quiet Sun's topological nature.
Aims: Topology is a tool to explain the complexity of the magnetic field, the occurrence of reconnecti…
High-resolution optical spectroscopy of Plaskett's star
Martins, F.; Gosset, E.; Rauw, G. +3 more
Context: Plaskett's star (
Radio-to-UV monitoring of AO 0235+164 by the WEBT and Swift during the 2006-2007 outburst

GMASS ultradeep spectroscopy of galaxies at z ~ 2 . I. The stellar metallicity
Berta, S.; Cimatti, A.; Daddi, E. +12 more
Context: Galaxy metallicities have been measured to redshift z∼2 by gas-phase oxygen abundances of the interstellar medium using the R{23} and N2 methods. Galaxy stellar metallicities provide crucial data for chemical evolution models but have not been assessed reliably much outside the local Universe.
Aims: We determine the iron-abundance, st…
XMM-Newton observations of the Small Magellanic Cloud: Be/X-ray binary pulsars active between October 2006 and June 2007
Pietsch, W.; Haberl, F.; Eger, P.
Aims: We analysed eight XMM-Newton observations toward the Small Magellanic Cloud (SMC), performed between October 2006 and June 2007, to investigate high mass X-ray binary systems.
Methods: We produced images from the European Photon Imaging Cameras (EPIC) and extracted X-ray spectra and light curves in different energy bands from sources tha…
An active region jet observed with Hinode
Young, P. R.; Mason, H. E.; Isobe, H. +4 more
Aims:We study the physical properties of an active region (AR) jet in order to probe the mechanisms responsible for it.
Methods: We report 2007 January 15/16 observations of a recurring jet situated on the west side of NOAA AR 10938. Multi-wavelength data from all three instruments onboard Hinode were analysed. This paper focuses on one instan…
First superburst from a classical low-mass X-ray binary transient
Brown, E. F.; in't Zand, J. J. M.; Kuulkers, E. +3 more
We report the analysis of the first superburst from a transiently accreting neutron star system with the All-Sky Monitor (ASM) on the Rossi X-ray Timing Explorer. The superburst occurred 55 days after the onset of an accretion outburst in
Determining the LIC H density from the solar wind slowdown
Liu, Y.; McComas, D. J.; Wang, C. +1 more
Context: The ionized solar wind interacts directly with the interstellar neutrals which flow into the heliosphere. These neutrals are ionized, mainly by charge exchange, then accelerated to the solar wind speed with the momentum and energy removed from the bulk flow of the solar wind. Thus, by measuring the solar wind slowdown, one can estimate th…
