We report a Swift follow-up observation of the very faint X-ray transient source XTE J1728-295 (also IGR J17285-2922, ATel #2825) currently in the decaying phase of its recent outburst (ATel #2823, #2824, #2869). The observation was performed on 2010-10-29 07:07:35 UTC for a duration of 2 ks, and was observed in Photon Counting (PC) mode

IBIS-ISGRI observations on 2010-10-10 (Bordas et al. ATel #2919) as well as RXTE-PCA scans on 2010-10-09 (http://lheawww.gsfc.nasa.gov/users/craigm/galscan/html/EXO_1745-248.html) showed enhanced X-ray emission from the direction of the globular cluster Terzan 5. We analysed a ~500 s Swift-XRT observation of the field starting on 2010-10-10 01:32

At high-z the most superdense massive galaxies are supposed to be the result of gas-rich mergers resulting in compact remnant. After this, dry mergers are expected to be the mechanism that moves these very massive galaxies towards the current stellar mass size relation. Within these merging scenarios, a non-negligible fraction (1-10%) of these

Context. Knowledge of the intrinsic shapes of galaxy components provides crucial information when constraining phenomena driving their formation and evolution. Aims: We analize the structural parameters of a magnitude-limited sample of 148 unbarred S0-Sb galaxies to derive the intrinsic shape of their bulges. Methods: We developed a new method to

Within the hierarchical framework for galaxy formation, minor merging and tidal interactions are expected to shape all large galaxies to the present day. As a consequence, most seemingly normal disk galaxies should be surrounded by spatially extended stellar "tidal features" of low surface brightness. As part of a pilot survey for such interaction

We present a series of numerical simulations aimed at understanding the nature and origin of turbulence in coronal loops in the framework of the Parker model for coronal heating. A coronal loop is studied via reduced magnetohydrodynamic (MHD) simulations in Cartesian geometry. A uniform and strong magnetic field threads the volume between the two
