An Adaptive Optics Survey for Companions to Stars with Extra-Solar Planets

J. P. Lloyd, M. C. Liu, J. R. Graham +12

We have undertaken an adaptive optics (AO) imaging survey of extrasolar planetary systems and stars showing interesting radial velocity trends from high precision radial velocity s…

Near-IR Spectroscopy and Population Synthesis of Super Star Clusters in NGC 1569

Andrea M. Gilbert, James R. Graham

We present H- and K-band NIRSPEC spectroscopy of super star clusters (SSCs) in the irregular starburst galaxy NGC 1569, obtained at the Keck Observatory. We fit these photospheric…

Three high-redshift millimeter sources and their radio and near-infrared identifications

F. Bertoldi, C. L. Carilli, K. M. Menten +11

We present millimeter wavelength detections of three faint sources that are most likely high-redshift starburst galaxies. For one of the sources, which was previously discovered wi…

K-Band Spectroscopy of an Obscured Massive Stellar Cluster in the Antennae Galaxies (NGC 4038/4039) with NIRSPEC

A. M. Gilbert, J. R. Graham, I. S. McLean +6

We present infrared spectroscopy of the Antennae Galaxies (NGC 4038/4039) with NIRSPEC at the W. M. Keck Observatory. We imaged the star clusters in the vicinity of the southern nu…

2 micron Spectroscopy within 0.3 arcseconds of SgrA*

Donald F. Figer, E. E. Becklin, Ian S. McLean +7

We present moderate (R~~2,700) and high resolution (R~~22,000) 2.02.4 \micron\ spectroscopy of the central 0.1 square arcseconds of the Galaxy obtained with NI…

An Imaging Fourier Transform Spectrometer for the Next Generation Space Telescope

James R. Graham

Due to its simultaneous deep imaging and integral field spectroscopic capability, an Imaging Fourier Transform Spectrograph (IFTS) is ideally suited to the Next Generation Space Te…
