Using high-resolution spectra of 8 Active Galactic Nuclei (AGN) observed with INT we found that shapes of narrow emission lines indicate very complex structure of the Narrow Line Region (NLR). We resolved, at least two kinematically separated emission regions: (i) one with narrower lines (~100 km/s) with shift that follows cosmological red-shift of

Sporadic cometary-like activity has been observed in three asteroids of the main belt (the Main Belt Comets, MBCs, Hsieh and Jewitt 2006, Science, 312, 561): (7968) Elst-Pizarro, 118401 (1999 RE70) and P/2005 U1 (Read). All of them are members of the Themis family. The study of this objects is of fundamental importance to address several

We report on deep radio images and optical spectroscopy of two BL Lac objects that have very close compact companions. The two targets, 1ES 0502+675 and 1ES 1440+122, were selected from the Hubble Space Telescope imaging survey of 110 BL Lacs as candidates for possible gravitational lensing. The new observations clearly demonstrate that the

Context. Galaxies, which often contain ionised gas, sometimes also exhibit a so-called low-ionisation nuclear emission line region (LINER). For 30 years, this was attributed to a central mass-accreting supermassive black hole (more commonly known as active galactic nucleus, AGN) of low luminosity, making LINER galaxies the largest AGN sub

The Antlia dwarf galaxy, recently found to be a possible local Group member, is analyzed using VI photometry. The galaxy is resolved into a large number of stars and although the galaxy is intrinsically faint and of low surface brightness, its stellar populations reveal characteristics more typical of faint star-forming dIrs rather than dEs

Recent data on, and interpretations of the Kleinmann-Low nebula are examined. It is suggested that associated high velocity gas is radiatively accelerated by a protostar in an early stage of premain-sequence contraction.
