We have carried out a complete analysis of the kinematics and the stellar populations of the double-barred S0 galaxy NGC 357. We have measured suitable absorption line strength indices on very high quality spectra. With the aid of stellar population models we have obtained the relative ages and metallicities for the different components to

APOGEE is a large-scale, NIR, high-resolution (R 20,000) spectroscopic survey of Galactic stars, and is one of the four experiments in the SDSS-III suite. APOGEE will provide, by orders of magnitude, the largest uniform database of chemical abundances, spectroscopic parallaxes and kinematics for Galactic stars across the bulge, disk, and halo. The

Context: The magnetic and kinematic properties of the photospheric Evershed flow are relatively well known, but not completely understood. The evolution of the flow with time, which is mainly due to the appearance of velocity packets called Evershed clouds (ECs), may provide information to further constrain its origin. Aims: We undertake a detailed

Context: NRAO 150, a compact and bright radio to mm source showing core/jet structure, has been recently identified as a quasar at redshift z = 1.52 through a near-IR spectral observation. Aims: To study the jet kinematics on the smallest accessible scales and to compute the first estimates of its basic physical properties. Methods: We have

The study of gas transport to the inner regions of galaxies is a fundamental aspect in our understanding of the way galaxies evolve. In this context, star-forming nuclear rings are key features as they contain large amounts of gas and are the sites where a significant fraction of the current star formation is taking place in their host galaxies

We present 5-40 μm spectroscopy of 41 planetary nebulae (PNe) in the Magellanic Clouds, observed with the Infrared Spectrograph on board the Spitzer Space Telescope. The spectra show the presence of a combination of nebular emission lines and solid state features from dust, superimposed on the thermal IR continuum. By analyzing the 25 LMC and 16
