Redshift and velocity dispersion of the cluster of galaxies around NGC 326
Redshifts of several galaxies thought to be associated with NGC 326 are determined. The results confirm the presence of a cluster and find a mean redshift of z = 0.0477 ± 0.0007 and a line-of-sight velocity dispersion σ z = 599 (+230, −110) km s −1. The velocity dispersion and previously measured X-ray gas temperature of kT ≃ 1.9 keV are consistent with the cluster σ z /kT relation, and NGC 326...
متن کاملFocused X-shaped pulses.
The space-time focusing of a (continuous) succession of localized X-shaped pulses is obtained by suitably integrating over their speed, i.e., over their axicon angle, thus generalizing a previous (discrete) approach. New superluminal wave pulses are first constructed and then tailored so that they become temporally focused at a chosen spatial point, where the wave field can reach very high inte...
متن کاملA multi - Frequency Study of The Radio Galaxy NGC 326 . I . The Data
We present the results of a multi-frequency study of the inversion symmetric radio galaxy NGC326 based The morphological, spectral and polarization properties of this peculiar object are studied at different levels of spatial resolutions. The interpretation of the data will be discussed in forthcoming papers.
متن کاملCommunicating Stream X-Machines Systems are no more than X-Machines
A version of the communicating stream X-machine model is proposed, which gives a precise representation of the operation of transferring data from one X-machine to another. For this model it is shown that systems of communicating Xmachines have the same computational power as single stream X-machines. This enable existing methods for deriving test strategies for stream X-machines to be extended...
متن کاملCentrosomes: Central no more?
It has recently been found that the zygotic development of a morphologically normal fly can occur without properly functioning mitotic centrosomes. Does this mean that centrosomes are not required for cell division in animals at all?
