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

We report on the results of a coordinated observation of Mrk 421 during outburst using data from XMM-Newton and ground-based TeV data from two Imaging Air Cherenkov Telescopes, the Whipple 10m telescope, based in Arizona, and the MAGIC telescope, based on La Palma in the Canary Islands. The coordinated effort between the two TeV groups allowed for

We investigate the assembly histories 56 of galaxy clusters using a pair of cosmological LCDM N-body simulations. We track infalling galaxy subhalos with masses large enough to host 0.1 L* galaxies , and find that the majority of cluster member galaxies experienced no ``pre-processing'' in the group environment prior to their accretion into the

Context: The footpoints of quiet Sun Transition Region (TR) loops do not seem to coincide with the photospheric magnetic structures appearing in traditional low-sensitivity magnetograms. Aims: We look for the so-far unidentified photospheric footpoints of TR loops using G-band bright points (BPs) as proxies for photospheric magnetic field
