Observations of clusters of galaxies : Virgo and M 87
We present results of a re-analysis of archival EUVE data of the central region of the Virgo cluster. We employ the new analysis method developed by Bowyer, Berghöfer & Korpela (1999) and find diffuse emission reaching out to a distance of ≈ 13. The spatial distribution of this flux is incompatible with a thermal plasma origin. We investigate whether this emission is due to inverse Compton scat...
متن کاملCompleting HI observations of galaxies in the Virgo Cluster
High sensitivity (rms noise ∼ 0.5 mJy) 21-cm H i line observations were made of 33 galaxies in the Virgo cluster, using the refurbished Arecibo telescope, which resulted in the detection of 12 objects. These data, combined with the measurements available from the literature, provide the first set of H i data that is complete for all 355 late-type (Sa-Im-BCD) galaxies in the Virgo cluster with m...
متن کاملHigh-speed video observations of rocket-and-wire initiated lightning
[1] We present observations of a rocket-and-wire triggered lightning flash obtained with high-speed video cameras recording 5400 and 50000 frames per second (frame times 185 ms and 20 ms) with time-synchronized current and electric field measurements. Transient leader channels were observed with precursor current pulses occurring before the development of the sustained upward positive leader th...
متن کاملUltraviolet exposure of Gafchromic XR‐RV3 and XR‐SP2 films
Gafchromic film has been used for X-ray dose measurement in diagnostic examinations. Their use has been initiated for three-dimensional X-ray dose measurement by using the high-resolution characteristics of Gafchromic films in computed tomography. However, it is necessary to solve the problem of nonuniform thickness in the active layers of Gafchromic films. A double exposure technique using X-r...
