High-precision wavelength calibration of astronomical spectrographs with laser frequency combs
M. T. Murphy, Th. Udem, R. Holzwarth +8
We describe a possible new technique for precise wavelength calibration of high-resolution astronomical spectrographs using femtosecond-pulsed mode-locked lasers controlled by stab…

Near-IR speckle imaging of massive young stellar objects
C. Alvarez, M. Hoare, A. Glindemann +1
We present near-IR speckle images of 21 massive Young Stellar Objects (YSOs) associated with outflows. The aim of this study is to search for sub-arcsecond reflection nebulae assoc…

The ROSAT HRI Point Spread Function
Peter Predehl, Almudena Prieto
A sample of the brightest point-like sources observed with the ROSAT-HRI were analysed to asses on the intrinsic shape of the ROSAT-HRI Point Spread Function (PSF). Almost all of t…
