Long γ-ray bursts and core-collapse supernovae have different environments
- A. Fruchter, A. Levan, +30 authors S. Woosley
- Physics
- Nature
- 20 March 2006
When massive stars exhaust their fuel, they collapse and often produce the extraordinarily bright explosions known as core-collapse supernovae. On occasion, this stellar collapse also powers an even… Expand
HST STIS Spectroscopy of the Triple Nucleus of M31: Two Nested Disks in Keplerian Rotation around a Supermassive Black Hole
- R. Bender, J. Kormendy, +12 authors B. Woodgate
- Physics
- 20 September 2005
We present Hubble Space Telescope (HST) spectroscopy of the nucleus of M31 obtained with the Space TelescopeImagingSpectrograph(STIS).SpectrathatincludetheCaiiinfraredtriplet(k ’ 85008)seeonlythered… Expand
On the Nature of the Central Source in η Carinae
- D. Hillier, K. Davidson, K. Ishibashi, T. Gull
- Physics
- 1 June 2001
Long-slit spectroscopic observations of η Carinae and its Homunculus have recently been obtained using STIS on the Hubble Space Telescope (HST). We have extracted the spectrum of the central source… Expand
Latitude-dependent Effects in the Stellar Wind of η Carinae
- N. Smith, K. Davidson, T. Gull, K. Ishibashi, J. Hillier
- Physics
- 20 January 2003
The Homunculus reflection nebula around η Carinae provides a rare opportunity to observe the spectrum of a star from more than one direction. In the case of η Car, the nebula's geometry is known well… Expand
The Shape and Orientation of the Homunculus Nebula
- K. Davidson, T. Gull, K. Ishibashi, D. Hillier
- Physics
- 1 March 2001
Doppler velocities give information about the three-dimensional shape and orientation of the bipolar ejecta of η Car. We report slit spectroscopy obtained using the Space Telescope Imaging… Expand
Observations of the Crab Nebula and Its Pulsar in the Far-Ultraviolet and in the Optical* **
- J. Sollerman, P. Lundqvist, +5 authors G. Sonneborn
- Physics
- 18 February 2000
We present far-UV observations of the Crab Nebula and its pulsar made with the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope. Broad, blueshifted absorption arising in the… Expand
M33: A galaxy with no supermassive black hole
- K. Gebhardt, T. Lauer, +9 authors D. Weistrop
- Physics
- 6 July 2001
Galaxies that contain bulges appear to contain central black holes whose masses correlate with the velocity dispersion of the bulge. We show that no corresponding relationship applies in the pure… Expand
The Space Telescope Imaging Spectrograph Design
- B. Woodgate, R. Kimble, +41 authors D. Weistrop
- Physics
- 1 October 1998
ABSTRACT The Space Telescope Imaging Spectrograph (STIS) instrument was installed on the Hubble Space Telescope (HST) during the second servicing mission, in 1997 February. Four bands cover the… Expand
The On-Orbit Performance of the Space Telescope Imaging Spectrograph
- R. Kimble, B. Woodgate, +85 authors T. Wolfe
- Physics
- 10 January 1998
The Space Telescope Imaging Spectrograph (STIS) was successfully installed into the Hubble Space Telescope (HST) in 1997 February, during the second HST servicing mission, STS-82. STIS is a versatile… Expand
