Spectroscopic data for 20 PNe in the irregular galaxy NGC6822 have been studied. This represents 80% of the total sample of PNe candidates in this galaxy. We discuss the kinematics of PNe in comparison to the kinematics of the HI disk and the young and intermediate age populations. In addition the chemical abundances of the sample have been

1985 was a year of inauguration for the Instituto de Astrofísica de Canarias (IAC). In that year its two observatories, the Observatorio del Roque de los Muchachos, on the island of La Palma, (where its 10.4m optical-NIR telescope vies with the world´s major instruments), and the Observatorio del Teide, on the island of Tenerife, as well as its

We carry out a direct search for bar-like non-circular flows in intermediate-inclination, gas-rich disc galaxies with a range of morphological types and photometric bar classifications from the first data release (DR1) of the Calar Alto Legacy Integral Field Spectroscopy Area (CALIFA) survey. We use the DISKFIT algorithm to apply rotation only and

Originally thought to explore the high redshift Universe, the extreme depth of the Frontier Fields survey provides also an excellent opportunity to explore with unprecedented detail the faintest component of the galaxy clusters: their intra-cluster light (ICL). In this contribution, we will show our analysis of the ICL of the cluster Abell 2744

Context. The Gaia-ESO Survey (GES) is a large public spectroscopic survey at the European Southern Observatory Very Large Telescope. Aims: A key aim is to provide precise radial velocities (RVs) and projected equatorial velocities (vsini) for representative samples of Galactic stars, which will complement information obtained by the Gaia astrometry

We report Spitzer/IRS spectra of a small sample of heavily obscured and high mass loss post-AGB stars with O-rich maser emission. IRAM 30 m observations for two post-AGBs are also reported. The Spitzer/IRS spectra show the C-rich character of their circumstellar envelopes (CSE), as revealed by the presence of small hydrocarbon molecules such as
