FOS Discoveries


 

The FOS GTO data analysis project

The FOS GTO data analysis project had its headquarters at UCSD and UCSD investigators continue to be active in HST research programs. Among the important results from the FOS team was conclusive evidence for the presence of a massive black hole in the nucleus of the nearby elliptical galaxy, M87.
FOS PROVES THE EXISTENCE OF MASSIVE BLACK HOLE

M87 Core & Accretion Disk Blue- and Red- shifted spectra

Shown above is a sample of the spectrum obtained by the UCSD Faint Object Spectrograph onboard the Hubble Space Telescope that provided proof of the existence of black holes. Also available is the full press release photo (180k GIF or 80k JPEG).

Hubble finds new black hole and unexpected mysteries

Confirming the presence of yet another super-massive black hole in the universe, astronomers using NASA's Hubble Space Telescope have also found unexpected new mysteries. The black hole and an 800 light-year-wide spiral-shaped disk of dust fueling it, are slightly offset from the center of their host galaxy, NGC 4261, located 100 million light-years away in the direction of the constellation Virgo.

FOS Composite Quasar Spectrum

(Originally from this STScI page)
This is a quasar spectrum, between 350 and 3000 Å, constructed from 284 FOS observations of 101 quasars with redshifts z > 0.33, as described in Zheng, W., et al. 1997 ApJ,475,469, from the 1 Feb issue of The Astrophysical Journal. This reduced archival data is made available courtesy of Wei Zheng.

The spectrum is available as a flat ASCII file:

The table columns are:
  • Rest wavelength (Å)
  • Relative flux
  • Error
  • RMS
