Aims. We study the geometry of the circumstellar environment of the B[e] supergiant star GG Car. Methods: We present observations acquired using the IAGPOL imaging polarimeter in combination with the Eucalyptus-IFU spectrograph to obtain spectropolarimetric measurements of GG Car across Hα at two epochs. Polarization effects along the emission line

We use long-slit spectra taken with the William Herschel Telescope on La Palma and high-resolution Hubble Space Telescope imaging to study the gas kinematic in the halo of the ultraluminous infrared/radio galaxy PKS1345+12 ( z=0.122). Our long-slit spectra show line splitting at the locations of massive star clusters ( 106

The last decade has seen an amazing transformation in our ideas about the central bulges of disk galaxies. We are probably only half-way through this change. In this talk I give an overview of three areas of my specific interest; all are presented as ingredients for further refining our concept of bulge. First, I discuss whether the inner few

We present the results of our preliminary study of all known Galactic PNe (included in the Kerber 2003 catalog) which are detected by the AKARI/FIS All-Sky Survey as identified in the AKARI/FIS Bright Source Catalog (BSC) Version β-1.

We present results on the study of 24 bulges of Sa galaxies observed with the integral-field unit SAURON at the William Herschel Telescope. Here we review some of the main features observed in our maps in terms of their kinematics and stellar populations, and unveil a rather complex picture in which the centers of spiral galaxies are made of

Using the Arcminute Microkelvin Imager (AMI) at 16GHz and the Very Small Array (VSA) at 33GHz to make follow-up observations of sources in the New Extragalactic WMAP Point Source catalogue, we have investigated the flux density variability in a complete sample of 97 sources over time-scales of a few months to ~1.5yr. We find that 53 per cent of the
