Although an LDDE formulation was firstly introduced to represent the XLF of AGNs detected with ROSAT
in the soft X-ray band, (54) the luminosity dependence of the peak redshift was not found.
In contrast to the theoretical research described above, calculations based on eight years of ROSAT
observations show that a galaxy's central black hole might gobble a close-passing star every 100,000 years or so.
all-sky survey in X rays really made the biggest difference" in finding these groups, says Jayawardhana.
There is an X-ray source in the ROSAT
catalogue (19) named 1RXS J190645.
Most parts of the car-sized ROSAT
research satellite were expected to burn up as they hit the atmosphere at speeds up to 280mph, but up to 30 fragments weighing a total of 1.
Is the second satellite to fall uncontrolled from space within a month.
in the ROSAT
North Ecliptic Pole X-ray survey and confirmed via optical spectroscopy, which showed features typical of a dwarf nova in quiescence.
data was like trying to identify a criminal from a blurry fingerprint.
The orbiting X-ray observatory ROSAT
ended its mission (154: 379).
The German Roentgen Satellite, or ROSAT
, has been drifting in Earth orbit since it was officially decommissioned in 1999.
4-ton Rontgensatellit, or ROSAT
, has been spinning aimlessly through space for 12 years after it was switched off in 1999 after its guidance system broke.
Dr Kellett is an X-ray astronomer who has worked on ROSAT
, and is now using X-ray techniques to work out the atomic composition of the Moon.
