High Spectral Resolution Observations of the Massive Stars in the Galactic Center
Angelle Tanner, Donald F. Figer, Paco Najarro +10
We present high-resolution near-infrared spectra, obtained with the NIRSPEC spectrograph on the W. M. Keck II Telescope, of a collection of hot, massive stars within the central 25…
High Precision Stellar Radial Velocities in the Galactic Center
Donald F. Figer
We present radial velocities for 85 cool stars projected onto the central parsec of the Galaxy. The majority of these velocities have relative errors of 1 km/s, or a factor o…
Kinematic Masses of Super Star Clusters in M82 from High-Resolution Near-Infrared Spectroscopy
Nate McCrady, Andrea M. Gilbert, James R. Graham
Using high-resolution (R~22,000) near-infrared (1.51 -- 1.75 microns) spectra from Keck Observatory, we measure the kinematic masses of two super star clusters in M82. Cross-correl…
Massive Stars in the Arches Cluster
Donald F. Figer, Francisco Najarro, Diane Gilmore +9
We present and use new spectra and narrow-band images, along with previously published broad-band images, of stars in the Arches cluster to extract photometry, astrometry, equivale…
Steps Toward Determination of the Size and Structure of the Broad-Line Region in Active Galactic Nuclei. XVI. A Thirteen-Year Study of Spectral Variability in NGC 5548
B. M. Peterson, the International AGN Watch
We present the final installment of an intensive 13-year study of variations of the optical continuum and broad H-beta emission line in the Seyfert 1 galaxy NGC 5548. The data base…
The Altitude of an Infrared Bright Cloud Feature on Neptune from Near-Infrared Spectroscopy
Henry G. Roe, James R. Graham, Ian S. McLean +8
We present 2.03-2.30 micron near-infrared spectroscopy of Neptune taken 1999 June 2 (UT) with the W.M. Keck Observatory's near-infrared spectrometer (NIRSPEC) during the commission…
