First observations of the X-ray transient EXO 2030+375 with IBIS/ISGRI
We present a first INTEGRAL observation of the 42 s transient X-ray pulsar EXO 2030+375 with IBIS/ISGRI. The source was detected during Cyg X-1 observations in...
First simultaneous UBVRI photopolarimetric observations of a sample of normal quasars
We present what we believe to be the first truly simultaneous UBVRI photopolarimetric results for a sample of eight 'normal' quasars. In five of these quasars...
Formulation of stellar speckle interferometry in terms of joint spatial/spatial-frequency representations
A generalized formulation of stellar speckle interferometry (SSI) and related techniques in terms of joint spatial/spatial-frequency energy representations are...
