New constraints on the continuum-emission mechanism of AGN: Intensive monitoring of NGC 7469 in the X-ray and ultraviolet [PDF]
, 1998 We have undertaken near-continuous monitoring of the Seyfert 1 galaxy NGC 7469 in the X-ray with RXTE over a ~30d baseline. The source shows strong variability with a root-mean-square (rms) amplitude of ~16 per cent, and peak-to-peak variations of a ...

Report on some Biological Responses to High Electric Fields and Indirect Action of Ultraviolot Rays [PDF]
Acta Medica Iranica, 1960 The similarities of effects produced hy radiation, electric field, ultraviolet rays and ozone on the platelet and blood corpuscles suggest the presence of a common factor. It is assumed that the effects of radiation is due the hydroperoxyl radical and we

X-ray confirmation of the intermediate polar HTCam [PDF]
, 2005 We report on the first pointed X-ray observations with XMM-Newton and RXTE satellites of the X-ray source RXJ0757.0+6306 = HT Cam. We detect a strong 515 s X-ray modulation confirming the optical photometric period found in 1998, which definitively ...

Compression of extreme-ultraviolet ultrashort pulses by grating configurations [PDF]
, 2015 The design and realization of grating instruments to condition the spectral phase of ultrashort extreme-ultraviolet pulses are discussed. The main application of such configurations is the temporal compression of pulses by compensating the phase chirp ...
