Between February 2010 and May 2011, our group has observed five stellar occultations by Trans-Neptunian Objects (TNOs), giving the size and shape for some of the biggest TNO's: Varuna, Eris, 2003 AZ84, Makemake and Quaoar. Here we present two of them: the January 08 stellar occultation by 2003 AZ84, and the May 04 by Quaoar. For the event of 2003

The data used in the publication consist of a set of CaII H spectra taken near and beyond the solar limb on 25/08/2009 at UT 08:43-09:15. The data were obtained with the POLIS instrument at the German VTT. The wavelength range covers the core and the blue wing of the CaII H line from 396.332nm to 396.969nm in 326 steps of 1.96pm. The observations

The far-infrared (FIR) properties of Quasi-Stellar Objects (QSOs) is important in connecting the Starburst (SB) and Active Galactic Nucleus (AGN) activities. Therefore, we constructed a 24 μ m selected QSO sample to study their FIR behavior. All sources were spectroscopically identified from MMT or the Sloan Digital Sky Survey (SDSS) as broadline

The now completed INT photometric H-alpha Survey (IPHAS) is a valuable resource to detect planetary nebulae (PNe) in the Northern Galactic Plane. An area of 1800 deg^2 of sky has been scanned and hundreds of new PN candidates have been discovered, from the direction of the crowded and dusty Galactic center to the less widely explored Galactic

Table3.dat lists only radial velocities used for the identification of the binary as a close or wide binary candidate. Table4.dat contains the total number of spectra used for identification of the binary, the number of spectra from own spectroscopic follow-up observations and the statistical significance of the radial velocity variations.

We report far-infrared (FIR) imaging of the Seyfert 2 galaxy NGC 3081 in the range 70-500 μm, obtained with an unprecedented angular resolution, using the Herschel Space Observatory instruments PACS and SPIRE. The 11 kpc (˜70 arcsec) diameter star-forming ring of the galaxy appears resolved up to 250 μm. We extracted IR (1.6-500 μm) nuclear fluxes
