. To display the state of any background jobs that you are currently running use the job command. For example: jobs [1] + Running xterm -g 90x55 [2] - Running xterm -g 90x55 . This displays the job number, its state and the command associated with this job. To display the process number use the -l option. For example: jobs -l [1] + 3584 Running xterm -g 90x55 [2] - 3587 Running xterm -g 90x55 .

Born in the UK, and following degrees at the Univerities of Bristol and Sussex, Martin Elvis got his PhD under Prof. Ken Pounds at the University of Leicester (UK) in 1978 for work with the Ariel V satellite. Ariel V was only the 2nd satellite to be devoted to X-ray astronomy. ... His PhD thesis demonstrated that powerful X-ray emission was a normal feature of Active Galactic Nuclei (or "AGN"). AGN X-ray emission has been a lively area of research ever since. ...

This deep image shows the COSMOS field imaged by the Canada France Hawaii Telescope (CFHT). Huge numbers of faint galaxies are visible. ... Most of the black holes in the centers of active galaxies in the past 11 billion years were not turned on by mergers between galaxies, as had been previously thought. Some of the active galaxies with supermassive black holes at their centers that were used in the new study are marked with red crosses on this picture. CFHT/IAP/Terapix/CNRS/ESO ...

This short exposure taken with the Kitt Peak 4-meter telescope clearly shows the large number of globular clusters that are associated with M87, the brightest elliptical galaxy in the Virgo cluster. The galaxy is also famous for having an active nucleus in which an outflow of collimated material is emanating. Note the very bright nucleus in the short exposure picture of M87 that helps to reveal the jet. M87 may mark the dynamical center of the Virgo cluster.
