Aims. Near diffraction-limited images have been taken at 8.9, 11.9, and 12.9 µm for the brightest extragalactic sources in the southern sky, in order to optimally plan N-band observations with MIDI (MID-infrared Interferometric instrument) at the VLTI. Methods. We have assembled a sample of 21 objects consisting of all the AGNs observable from Paranal observatory, Chile, plus three non-AGN objects, with an estimated N-band flux greater than 400 mJy. We used the TIMMI2 Mid Infrared instrument mounted on the ESO's 3.6 m telescope to obtain near diffraction-limited images in order to establish the unresolved core flux within <0.5 arscsec.Results. Positions and core total fluxes were obtained for all sources in our sample and compared with similar investigations in the literature. We find that 15 AGN and the nuclear starburst in NGC 253 exhibit an unresolved core flux <300 mJy at 11.9 µm, making them promising targets for MIDI at the VLTI. For extended sources, near diffraction-limited images are presented and discussed.

Aims. We investigated the cloud of ejecta resulting from the mass loss associated with the final helium shell flash in V605 Aql. Methods. V605 Aql was imaged at high spatial resolution in both optical emission lines and the infrared continuum using HST/WFPC2 and Gemini/Hokupa'a+QUIRC, respectively. The He I 10 830 Å spectrum was also observed. Results. The obscuring circumstellar shell, whose effects were first seen in 1923, is shown to be a disk with extended structure, including knots. The morphology of the V605 Aql circumstellar shell is discussed as an 80 year old in an evolutionary sequence consisting of recent, as well as much older, final flash objects. Conclusions. The obscuration of V605 Aql by dust marked the emergence of the hot white dwarf remnant from an optically thick pseudo-photosphere. This white dwarf drives a 2500 km s −1 wind principally in one plane resulting in a circumstellar disk. Where the wind encounters the circumstellar disk, He I 10 830 Å emission is created, and hot, ∼1500 K, grains are generated. Grains exit the disk at 350 K, and the accompanying gas then expands at ∼140 km s −1 . The strong concentration of the mass loss to the disk suggests the white dwarf is now rotating rapidly. There is convincing evidence in the literature that this process is also seen in V4334 Sgr and is still going on in the old final flash objects A30 and A78.

“…Further mid-infrared observations were performed with the Thermal Infrared Multimode Instrument TIMMI2 (Reimann et al 2000) mounted on the ESO 3.6 m telescope. TIMMI2 can operate like a spectrograph and imager in the M(5 µm), N(10 µm) and Q(20 µm) atmospheric bandpasses.…”

Abstract. We present infrared imaging and spectroscopic data of the complex massive star-forming region G10.47+0.03. The detection of seven mid-infrared (MIR) sources in our field combined with a sensitive Ks/ISAAC image allows to establish a very accurate astrometry, at the level of 0. 3. Two MIR sources are found to be coincident with two ultracompact H  regions (UCH s) within our astrometric accuracy. Another MIR source lies very close to three other UCH  regions and to the hot molecular core (HMC) in G10.47+0.03. Spectroscopy of two of the most interesting MIR sources allows to identify the location and spectral type of the ionizing sources. We discuss in detail the relationship between the HMC, the UCH  regions and the nearby MIR source. The nature of the other MIR sources is also investigated.
