The array was designed to detect compact radio sources such as these by virtue of the fact that they would scintillate (twinkle) when observed from the Earth through the interplanetary medium ? ... One of Antony Hewish?s research students, Jocelyn Bell, was set the task of operating the telescope and inspecting the daily charts for the kind deflections in the trace which occurred when a scintillating source passed over the array. ...

... The Workshop is dedicated to QCD Phase Transitions and observational signals of these Transitions related to formation of compact astrophysical objects. The aim of this workshop is to bring together researchers working on the problems of the behavior and observability of matter under critical conditions achievable in such astrophysical objects as 'strange' or 'hybrid' stars and in laboratories at heavy-ion collisions to discuss fundamental issues and recent developments. ...

The high-redshift radio-loud quasar PKS 2126-158 is found to have a large number of red galaxies in close apparent proximity.We use the Gemini Multi-Object Spectrograph (GMOS) on Gemini South to obtain optical spectra for a large fraction of these sources. We show that there is a group of galaxies at z 0.66, coincident with a metal-line absorption system seen in the quasar s optical spectrum. ... All confirmed members exhibit early-type galaxy spectra, a rare situation for a MgII absorbing system. ...
