Aims: We study the feedback of star formation and nuclear activity on the chemistry of molecular gas in NGC 1068, a nearby (D = 14 Mpc) Seyfert 2 barred galaxy, by analyzing whether the abundances of key molecular species such as ethynyl (C2H), which is a classical tracer of photon dominated regions (PDR), change in the different environments of

The object CXOM31 J004245.9+411036, reported as a new X-ray source in ATel #1859 from M31 Chandra observations, is the previously reported XMMU J004245.9+411036 (Pietsch et al. 2008, ATel #1647). We thank W. Pietsch and M. Henze for kindly bringing this clerical error to our attention. This transient source has been observed by various space

We present first preliminary results from AKARI/FIS pointed observations of post-AGB stars and planetary nebulae (PNe). A first analysis of the radial (azimuthally averaged) profile of the observed sources shows no evidence for excess emission due to the presence of circumstellar dust. No (detached) circumstellar faint dust-shells are seen in the

We present an atlas of position-velocity (PV) diagrams of ionized gas in the inner regions of 23 disk galaxies. The gas kinematics have been obtained from ground-based long-slit spectra along the major axis. We discuss the variety of shapes of the emission lines in the PV diagrams that we find for the sample galaxies. To discuss the different

Aims: We aim at constraining evolutionary models at low mass and young ages by identifying interesting transiting system members of the nearest OB association to the Sun, Upper Scorpius (USco), which has been targeted by the Kepler mission. Methods: We produced light curves for M-dwarf members of the USco region that has been surveyed during the

Relativistic plasma jets are observed in many systems that host accreting black holes. According to theory, coiled magnetic fields close to the black hole accelerate and collimate the plasma, leading to a jet being launched1-3. Isolating emission from this acceleration and collimation zone is key to measuring its size and understanding jet
