Multiple collimated outflows in a planetary nebula?
We present high resolution images and high dispersion spectra of the planetary nebula IC 4593. Benefiting from superb seeing (0″.4), the narrowband images...
MUSE crowded field 3D spectroscopy in NGC 300. I. First results from central fields
Aims: As a new approach to the study of resolved stellar populations in nearby galaxies, our goal is to demonstrate with a pilot study in NGC 300 that integral...
MUSE spectroscopy of planetary nebulae with high abundance discrepancies
We present MUSE deep integral-field unit spectroscopy of three planetary nebulae (PNe) with high-abundance discrepancy factors (ADF > 20): NGC 6778, M 1-42, and...
MUSE spectroscopy of the high abundance discrepancy planetary nebula NGC 6153
Context. The abundance discrepancy problem in planetary nebulae (PNe) has long puzzled astronomers. NGC 6153, with its high abundance discrepancy factor (ADF ~...
Narrow band survey for intragroup light in the Leo HI cloud. Constraints on the galaxy background contamination in imaging surveys for intracluster planetary nebulae
We have observed emission line objects located in a 0.26 deg2 field in the M 96 (Leo) group, coincident with the intergalactic HI cloud. The emission line...
Nature Versus Nurture: the Influence of the Environment in the Formation of Asymmetries
The association of a star with the different galactic components determines on a first order its velocity within the Galaxy. This stellar motion influences the...
Near infrared photometry of IRAS sources with colours like planetary nebulae. III
We present the near infrared photometry of a new sample of 225 IRAS sources, many of them previously unidentified in the literature, selected because their far...
Near infrared survey of IRAS sources with colours like planetary nebulae. II
Near-IR standard photometry (J, H, K, L and M bands) of 38 IRAS sources with FIR colors similar to those of known planetary nebulae is presented. They are...
