Clusters of Galaxies: magnetic fields and nonthermal emission
H. J. Voelk, A. M. Atoyan
The nonthermal particle content of galaxy clusters should in part have a cosmological component generated during the early starburst phase of the member galaxies. This is reviewed…
The time structure of Cherenkov images generated by TeV gamma-rays and by cosmic rays
HEGRA Collaboration, M. Hess et al
The time profiles of Cherenkov images of cosmic-ray showers and of gamma-ray showers are investigated, using data gathered with the HEGRA system of imaging atmospheric Cherenkov te…
The 3-D structure of the Virgo cluster from H band Fundamental Plane and Tully-Fisher distance determinations
G. Gavazzi, A. Boselli, M. Scodeggio +2
We undertook a surface photometry survey of 200 galaxies in the Virgo cluster (complete to B<14.0 mag) carried out in the near-Infrared (NIR) H band. Combining velocity dispersion…
Isophot Observations of Comet Hale-Bopp: Initial Data Reduction
E. Grün, S. B. Peschke, M. Stickel +17
Comet Hale-Bopp was observed five times with ISOPHOT, the photometer on board the Infrared Space Observatory (ISO). Each time broadband photometry was performed using 4 different d…
Observations of electromagnetically coupled dust in the Jovian magnetosphere
H. Krüger, E. Grün, A. Graps +2
We report on dust measurements obtained during the seventh orbit of the Galileo spacecraft about Jupiter. %which had a close flyby at Ganymede. The most prominent features observed…
Three years of Galileo dust data: II. 1993 to 1995
H. Krüger, E. Grün, D. P. Hamilton +18
Between Jan 1993 and Dec 1995 the Galileo spacecraft traversed interplanetary space between Earth and Jupiter and arrived at Jupiter on 7 Dec 1995. The dust instrument onboard was…
The tilt of the Fundamental Plane of Early-type galaxies: wavelength dependence
M. Scodeggio, G. Gavazzi, E. Belsole +2
The photometric parameters R_e and mu_e of 74 early-type (E+S0+S0a) galaxies in the Coma cluster are derived for the first time in the near IR H band. These are used, coupled with…
Three years of Ulysses dust data: 1993 to 1995
H. Krüger, E. Grün, M. Landgraf +18
The Ulysses spacecraft is orbiting the Sun on a highly inclined ellipse (). After its Jupiter flyby in 1992 at a heliocentric distance of 5.4 AU, the spacecraft rea…
Starburst in the Intragroup Medium of Stephan's Quintet
Cong Xu, Richard Tuffs
Based on new ISO mid-infrared observations and ground based and near-infrared observations, we report the detection of a bright starburst in the intragroup medium (IGM) of th…
Inverse Compton Emission of TeV Gamma Rays from PSR B1259-63
J. G. Kirk, Lewis Ball, Olaf Skjaeraasen
We derive light curves for the hard gamma-ray emission, at energies up to several TeV, expected from the unique pulsar/Be-star binary system PSR B1259-63. This is the only known sy…
Spectral universality of strong shocks accelerating charged particles
M. A. Malkov
As a rule, the shock compression controls the spectrum of diffusively accelerated particles. We argue that this is not so if the backreaction of these particles on the shock struct…
Ion leakage from quasiparallel collisionless shocks: implications for injection and shock dissipation
M. A. Malkov
A simplified model of particle transport at a quasiparallel one-dimensional collisionless shock is suggested. In this model the MHD-turbulence behind the shock is dominated by a ci…
EROS and MACHO Combined Limits on Planetary Mass Dark Matter in the Galactic Halo
EROS Collaboration, MACHO Collaboration
The EROS and MACHO collaborations have each published upper limits on the amount of planetary mass dark matter in the Galactic Halo obtained from gravitational microlensing searche…
Particle acceleration and synchrotron emission in blazar jets
J. G. Kirk, F. M. Rieger, A. Mastichiadis
We model the acceleration of electrons at a shock front in a relativistic blazar jet and compute the radiation they emit in a post-shock region which contains a homogeneous magneti…
Locating TeV Gamma-Ray Sources with Sub-Arcminute Precision: the Pointing Calibration of the HEGRA System of Imaging Atmospheric Cherenkov Telescopes
G. Puehlhofer, A. Daum, G. Hermann +4
Stereoscopic viewing of TeV gamma-ray air showers with systems of Imaging Atmospheric Cherenkov Telescopes (IACTs) allows to reconstruct the origin of individual primary particles…
Changes of the cosmic-ray mass composition in the 10^{14} - 10^{16} eV energy range
K. Bernlohr, W. Hofmann, G. Leffers +3
Changes of the cosmic-ray mass composition at the `knee' of the cosmic-ray flux spectrum near 10^{15} eV energy are investigated using data from ten Cosmic Ray Tracking (CRT) detec…
