Solid-state disk amplifiers for fusion-laser systems
A review is presented of the design, performance, and operation of large-aperture (10-46 cm) solid-state disk amplifiers for use in laser systems. We present design data, prototype tests, simulations, and projections for ...
NGC 206, a hole in M31
New high resolution 21 cm line observations of M31 show that the interstellar medium of this galaxy contains numerous holes in the H I distribution, some of which are clearly correlated with OB-associations. These holes ...
The X-ray cataclysmic variable 1E0643.0 −1648
We have used a new simultaneous IR/optical high-speed photometer on the UK IR telescope to study the recently discovered X-ray cataclysmic variable 1E0643.0−1648 (refs 1, 2). The light curve of this object obtained by the ...
Infrared and optical polarization of Markarian-421
Observations of the polarization of Mrk 421 in the V, J, and K bands are presented. The infrared radiation shows variable polarization with a range of at least 2-4%. The spectrum of the nonthermal source in the VJK regions ...
Linear polarization of T-Tauri stars
Linear polarization observations over the wavelength range 0.44-2.2 microns are presented for six T Tauri type stars. All of the stars studied show substantial polarization in the infrared, while T Tau itself (and probably ...
