We present a stellar population analysis of the absorption line strength maps for 48 early-type galaxies from the SAURON sample. Using the line strength index maps of Hβ, Fe5015 and Mgb, measured in the Lick/IDS system and spatially binned to a constant signal-to-noise ratio, together with predictions from up-to-date stellar population models, we

Near-Earth asteroid 101955 (1999 RQ36; henceforth RQ36) is particularly interesting. It's especially accessible to spacecraft and is the primary target of NASA's OSIRIS-REx sample return mission; it's also a potentially hazardous asteroid (Milani et al. 2009). We combine dynamical and spectral information to identify the most likely main-belt

Galaxy mergers and interactions are mechanisms which should drive the formation of bars. Therefore, we could expect that the fraction of barred galaxies increases with the local density. Here we show the first results of an extensive search for barred galaxies in different environments. We conclude that the bar fraction on bright (L>L*) field

Spectroscopy has shown the presence of CN band dichotomy and Na-O anticorrelations for 50-70 per cent of the investigated samples in the cluster 47 Tuc, otherwise considered a `normal' prototype of high-metallicity clusters from its photometric analysis. These anomalies are also found in main-sequence stars, suggesting that a consistent second

We are obtaining deep multiwavelength data of a sample of nearby blue compact dwarf galaxies (BCDGs) combining broad-band optical/NIR and Hα photometry, optical spectroscopy and 21-cm radio observations. Here we present HI results obtained with the Australia Telescope Compact Array for some BCDGs, all showing evident interaction features in their

The transient LMXB and 11 Hz pulsar currently in outburst in Terzan 5 (ATEL #2919, #2920, #2922, #2924, #2932) has been recently observed to show at least one eclipse of 511 s duration (ATEL #2929). We have checked the Chandra lightcurves (readout streak and dust-scattered halo) from the 2000 July 24 observation (Heinke et al. 2003, ApJ, 590, 809)
