We observed NGC 4151 on six separate occasions at intervals of one to three days using the Hopkins Ultraviolet Telescope during the flight of Astro-2 aboard the space shuttle Endeavour in March 1995....
Sloan Digital Sky Survey: Early data release (2002)

Feldman, Paul D., Burgh, Eric B., Durrance, Samuel T., Davidsen, Arthur F.
Far-ultraviolet spectra of Venus and Mars in the range 820-1840 A at 4 A resolution were obtained on 13 and 12 March 1995, respectively, by the Hopkins Ultraviolet Telescope (HUT), which was part of...
The Very Highly Ionized Broad Absorption Line System of the QSO SBS1542+541 (1998)
Telfer, Randal C., Kriss, Gerard A., Zheng, Wei, Davidsen, Arthur F., Green, Richard F.
We have analyzed the broad absorption line system of the bright (V=16.5) high-redshift (z=2.361) QSO SBS1542+541 using UV spectra from the HST FOS along with optical data from the MMT and the Steward...
The He II Opacity of the Lyman-alpha Forest and the Intergalactic Medium (1997)
Zheng, Wei, Davidsen, Arthur F., Kriss, Gerard A.
Based on the empirical formulas governing the distribution of Ly-a forest absorption, we use a Monte-Carlo technique to calculate the average HeII optical depth produced by these forest lines. A...
Evolution of Structure in the Intergalactic Medium and the Nature of the Ly-alpha Forest (1996)
Bi, HongGuang, Davidsen, Arthur F.
We have performed a detailed statistical study of the evolution of structure in a photoionized intergalactic medium (IGM) using analytical simulations to extend the calculation into the mildly...
Dixon, W. Van Dyke, Davidsen, Arthur F., Dorman, Ben, Ferguson, Harry
The globular cluster M79 was observed with the Hopkins Ultraviolet Telescope (HUT) during the Astro-1 space shuttle mission in 1990 December. The cluster's far-UV integrated spectrum shows strong...
