The re-flight of the Colorado high-resolution Echelle stellar spectrograph (CHESS): improvements, calibrations, and post-flight results
Keri Hoadley, Kevin France, Nicholas Kruczek +7
In this proceeding, we describe the scientific motivation and technical development of the Colorado High-resolution Echelle Stellar Spectrograph (CHESS), focusing on the hardware a…
The SLICE, CHESS, and SISTINE Ultraviolet Spectrographs: Rocket-borne Instrumentation Supporting Future Astrophysics Missions
Kevin France, Keri Hoadley, Brian T. Fleming +4
NASA's suborbital program provides an opportunity to conduct unique science experiments above Earth's atmosphere and is a pipeline for the technology and personnel essential to fut…
Absorption-Line Detections of K Gas in Spiral-Rich Groups of Galaxies
J. T. Stocke, B. A. Keeney, C. W. Danforth +10
Using the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST) the COS Science Team has conducted a high signal-to-noise survey of 14 bright QSOs. In a previous pa…
An HST/COS Survey of the Low-Redshift IGM. I. Survey, Methodology, & Overall Results
Charles W. Danforth, Brian A. Keeney, Evan M. Tilton +12
We use high-quality, medium-resolution {\it Hubble Space Telescope}/Cosmic Origins Spectrograph (\HST/COS) observations of 82 UV-bright AGN at redshifts to construct…
H2 Excitation Structure on the Sightlines to delta Scorpius and zeta Ophiucus - First Results from the Sub-orbital Local Interstellar Cloud Experiment
Kevin France, Nicholas Nell, Robert Kane +3
We present the first science results from the Sub-orbital Local Interstellar Cloud Experiment (SLICE): moderate resolution 1020-1070A spectroscopy of four sightlines through the lo…
From Protoplanetary Disks to Extrasolar Planets: Understanding the Life Cycle of Circumstellar Gas with Ultraviolet Spectroscopy
Kevin France, Matthew Beasley, David R. Ardila +20
Few scientific discoveries have captured the public imagination like the explosion of exoplanetary science during the past two decades. This work has fundamentally changed our pict…
On the Significance of Absorption Features in HST/COS Data
Brian A. Keeney, Charles W. Danforth, John T. Stocke +2
We present empirical scaling relations for the significance of absorption features detected in medium resolution, far-UV spectra obtained with the Cosmic Origins Spectrograph (COS)…
Characterizing CO Fourth Positive Emission in Young Circumstellar Disks
Rebecca Schindhelm, Kevin France, Eric Burgh +5
Carbon Monoxide is a commonly used IR/sub-mm tracer of gas in protoplanetary disks. We present an analysis of ultraviolet CO emission in {HST}-COS spectra for 12 Classical T Tauri…
Multiwavelength Observations of A0620-00 in Quiescence
C. S. Froning, A. G. Cantrell, T. J. Maccarone +17
[Abridged.] We present multiwavelength observations of the black hole binary system, A0620-00. Using the Cosmic Origins Spectrograph on the Hubble Space Telescope, we have obtained…
An HST/COS Search for Warm-Hot Baryons in the Mrk421 Sightline
Charles W. Danforth, John T. Stocke, Brian A. Keeney +4
Thermally-broadened Lya absorbers (BLAs) offer an alternate method to using highly-ionized metal absorbers (OVI, OVII, etc.) to probe the warm-hot intergalactic medium (WHIM, T=10^…
The Far-Ultraviolet "Continuum" in Protoplanetary Disk Systems II: CO Fourth Positive Emission and Absorption
Kevin France, Rebecca Schindhelm, Eric B. Burgh +21
We exploit the high sensitivity and moderate spectral resolution of the -Cosmic Origins Spectrograph to detect far-ultraviolet spectral features of carbon monoxide (CO) presen…
Diffuse Far-UV Line Emission from the Low-Redshift Lyman Break Galaxy Analog KISSR242
Kevin France, Nicholas Nell, James C. Green +1
We present new ultraviolet (UV) observations of the luminous compact blue galaxy KISSR242, obtained with the HST-COS. We identify multiple resolved sub-arcsecond near-UV sources wi…
