WebThe first direct image of a supermassive black hole, located at the galactic core of Messier 87. It shows radio-wave emission from a heated accretion ring orbiting the object at a mean separation of 350 AU, or ten times larger than the orbit of Neptune around the Sun. The dark center is the event horizon and its shadow. The image was released in 2024 by the … WebThe Cosmic Origins Spectrograph (COS) is a fourth-generation instrument that was installed on the Hubble Space Telescope (HST) during the 2009 servicing mission. COS is designed to perform high sensitivity, moderate- and low-resolution spectroscopy of astronomical objects in the 115-320 nm wavelength range. gmail select emails older than

Web1 apr. 2015 · For a full description of the FOS, see Harms and Fitch (1991). The observational data were processed using the standard ESO MIDAS package. We analyzed HST/FOS spectra of the EU UMa system using the G130H grating and 4.3 aperture, and HST/FOS spectra for ST LMi using the E140L grating and the 52 × 0.2 aperture. WebI analyze the accuracy of the FOS pipeline wavelength calibration for the FOS/RD detector with the G570H grating. I use observations of arc spectra and external targets that I obtained in the context of studies of galactic nuclei, comple- mented with an observation of the planetary nebula NGC 6833 obtained by the FOS Instrument Science Team.

WebWe report an eclipse mapping analysis of time-resolved ultraviolet spectroscopy covering three eclipses of the dwarf nova IP Pegasi on the late decline of the 1993 May outburst. The eclipse maps of the first run show evidence of one spiral arm, suggesting that spiral structures may still be present in the accretion disc 9 days after the onset of the outburst.
