V.M. Slipher and the Development of the Nebular Spectrograph
Laird A. Thompson
Vesto Melvin Slipher was the first astronomer to clearly define the factors that determine the "speed" of a nebular spectrograph. This brief historical summary recounts the way the…
An Historical View: The Discovery of Voids in the Galaxy Distribution
Laird A. Thompson, Stephen A. Gregory
Voids in the large scale distribution of galaxies were first recognized and discussed as an astrophysical phenomenon in two papers published in 1978. We published the first (Gregor…
Vesto Slipher and the First Galaxy Redshifts
Laird A. Thompson
Priority in the discovery of the velocity-distance relationship may be shifting from Edwin Hubble to Georges Lemaitre, but any reassessment of credit must also consider the contrib…
10^{-7} contrast ratio at 4.5Lambda/D: New results obtained in laboratory experiments using nano-fabricated coronagraph and multi-Gaussian shaped pupil masks
Abhijit Chakraborty, Laird A. Thompson, Mike Rogosky
We present here new experimental results on high contrast imaging of 10^{-7} at 4.5Lambda/D (Lambda = 0.820 microns) by combining a circular focal plane mask (coronagraph) of 2.5La…
Rayleigh Laser Guide Star Systems: UnISIS Bow Tie Shutter and CCD39 Wavefront Camera
Laird A. Thompson, Scott W. Teare, Samuel L. Crawford +1
Laser guide star systems based on Rayleigh scattering require some means to deal with the flash of low altitude laser light that follows immediately after each laser pulse. These s…
Rayleigh Laser Guide Star Systems: Application to UnISIS
L. A. Thompson, S. W. Teare
Laser guide stars created by Rayleigh scattering provide a reasonable means to monitor atmospheric wavefront distortions for real-time correction by adaptive optics systems. Becaus…
