The unusual multi-wavelength SED of two optical dropout galaxies
We have used deep optical, near-IR, and IR observations from VLT, Spitzer, Herschel, and LABOCA in strong lensing clusters to study distant galaxies. In...
Asteroid (2579) Spartacus is a small V-type object located in the inner main belt (the main delivery region for meteorites). It shows spectral characteristics...
The upcoming spectroscopic powerhouses at the Isaac Newton Group of Telescopes
The Isaac Newton Group of Telescopes is completing a strategic change for the scientific use of its two telescopes, the 4.2-m William Herschel Telescope (WHT)...
For more than ten years, the GREGOR Infrared Spectrograph (GRIS) has been the main spectropolarimeter on the GREGOR telescope since its inauguration in 2012...
The use of alternative energies is becoming common in many places around the world. It is envisaged that most large projects will consider the use of...
The use of sodium layer density anisotropies to fully measure the atmospheric turbulence, including tip-tilt, focus, and higher order aberrations
It is well known that Adaptive Optics (AO) observations do require the availability of natural stars (beside laser guide stars - LGSs) to obtain the tip-tilt...
The Use of Spectro-Polarimetric Measurements to determine the Plasma Heating
We present the possible use of spectro-polarimetric measurements on a set of data recorded with La Palma Stokes Polarimeter attached to the Swedish Vacuum Solar...
