The Tenerife beam-switching radiometers have now surveyed an area of one steradian with a resolution of 5 deg to 15 deg. Observations with scaled antennas are...
The results of four years of observation of the Crab Nebula at TeV energies by the Whipple group are discussed and the status of the Crab Nebula as a standard...
We present mid-IR observations taken with CanariCam at Gran Telescopio Canarias of the quadruply lensed quasar QSO2237+0305. We have obtained flux ratios...
Observations of the Giant Radio Galaxy M87 in the 100 GeV Energy Domain with the MAGIC Telescope
Since 2005 the giant radio galaxy M87 has been observed in the 100 GeV energy domain with the MAGIC Telescope. Results from the analysis of those observations...
Observations of the Jet-Like Structure Associated with the Binary Planetary Nebula GLMP 621
GLMP 621 (IRAS 17395-0841) was first identified as a possible new planetary nebula on the basis of its IRAS colors (García-Lario et al. 1997). A few years ago...
Observations of the Joint Action of the Hanle and Zeeman Effects in the D_2 Line of Ba II
We show a selection of high-sensitivity spectropolarimetric observations obtained over the last few years in the Ba II D_2-line with the Zürich Imaging...
Observations of the magnetic fine structure of a facula.
Simultaneous spectropolarimetric observations of a facula have been carried out in 10 spectral lines with a spatial resolution of 1arcsec. Local variations of...
