LP-Infinity: overcoming limits to the number of lifetime positions in the COS FUV channel
David J. Sahnow, Christian I. Johnson
Since the Cosmic Origins Spectrograph (COS) was installed on the Hubble Space Telescope (HST) in 2009, thousands of spectra have been collected with the Far Ultraviolet (FUV) chann…
COS2035: Extending COS/FUV Operations Through the 2030s
Marc Rafelski, David Sahnow, Christian I. Johnson +29
The far-ultraviolet (FUV) detector of the Cosmic Origins Spectrograph (COS) accumulates gain sag where photons land, and without continued mitigation this degradation would render…
Pushing the limits of the Cosmic Origin Spectrograph (COS) with an optimized background correction
Svea Hernandez, Andrei Igoshev, Jo Taylor +2
Observations utilizing the ultraviolet capabilities of the Cosmic Origin Spectrograph (COS) onboard the Hubble Space Telescope are of unique value to the astronomy community. Spect…
The Cosmic Origins Spectrograph: On-Orbit Instrument Performance
S. Osterman, J. Green, C. Froning +31
The Cosmic Origins Spectrograph (COS) was installed in the Hubble Space Telescope in May, 2009 as part of Servicing Mission 4 to provide high sensitivity, medium and low resolution…
ACCESS: Enabling an Improved Flux Scale for Astrophysics
Mary Elizabeth Kaiser, Jeffrey W. Kruk, Stephan R. McCandliss +20
Improvements in the precision of the astrophysical flux scale are needed to answer fundamental scientific questions ranging from cosmology to stellar physics. The unexpected discov…
