The advances in bolometric detector technology during the last 15 years have allowed (sub)millimetre wavelength measurements to contribute important data to some of the most challenging questions in observational cosmology. The availability of large-format filled-array cameras during the next decade, however, promises to provide FIR to millimetre

The paper describes the different methods, used in the MAGIC experiment, to unfold experimental energy distributions of cosmic ray particles (γ-rays). Questions and problems related to the unfolding are discussed. Various procedures are proposed which can help to make the unfolding robust and reliable. The different methods and procedures are

Results from B and R CCD observations of the X-ray Binary system MX0656-072 High Mass X-Ray Binaries are given. No optical pulsations was found from the X-Ray Pulsar.

The GTC project office is continuing to develop the plans for the commissioning of the GTC. The commissioning will start before first light, and will continue until well after normal science operations begin. The aim of the commissioning is to convert a series of subsystems into a single instrument which is capable of delivering high quality

We report on the first joint search for gravitational waves by the TAMA and LIGO collaborations. We looked for millisecond-duration unmodeled gravitational-wave bursts in 473 hr of coincident data collected during early 2003. No candidate signals were found. We set an upper limit of 0.12 events per day on the rate of detectable gravitational-wave
