Dense regions reach a maximum size and then fall back into a bound object like a cluster of galaxies. Once the cluster is formed, its physical size remains essentially constant. The space-time diagram below . shows a dense region in blue on the left. ... The galaxies in the blue region are accelerating more just because the region is denser and therefore has higher gravitational forces. ... Tutorial : Part 1 | Part 2 | ...

... We have been upgrading the software front-end to WASP (Wideband Autocorrelating SPectrometer, operating from 800 to 4000 MHz) from Lynx-OS to Real-Time Linux and will discuss Real-Time software aspects. We are using a standard parallel ``PIO'' card to receive data from the spectrometer and standard GPIB interfaces that drive a frequency synthesizer for bandpass calibration. WASP and its front-end computer are fully mobile and can be taken to any suitable radio telescope. ...
