We define blue E/S0 galaxies as objects having a clear early-type morphology on the HST/ACS images but with a blue rest-frame color. We isolate this way 210 IAB 22 blue early-type galaxies with M* / Msun > 1010 in the COSMOS field located in three redshift bins (0.2 z 0.55, 0.55 z 0.8, 0.8 z 1.4) and study their properties (number density

We present preliminary results of our HI WSRT observations of early-type galaxies in the ATLAS3D sample. We discuss the dependence of HI properties on environment. We detect HI in about half of the galaxies outside the Virgo cluster. The HI morphology/kinematics changes as a function of environment, going from regular, rotating systems around

We report on RXTE observations of the neutron star transient currently active in Terzan 5 (also known as IGR J17480-2446; ATels #2919, #2920, #2922, #2924, #2929, #2932, #2933, #2937, #2939, #2940, #2946), which has recently turned into a Z source (Altamirano et al., ATel #2952). The X-ray burst rate has increased gradually (see also ATels #2939,

An RXTE pointed observation of the ongoing outburst of of the transient source in the globular cluster Terzan 5 (ATEL #2919, #2920, #2922, #2924, #2929) began at approximately 2010-10-13 at 00:13 UTC, for an exposure of 3.2 ksec. This observation revealed strong pulsations at a barycentric frequency of 11.0452(2) Hz as well as one Type I X-ray

The study of cool atmospheres is currently a fruitful field of interaction between theorists developing better atmosphere models and observers discovering new cool objects and analysing their emission spectrum. Save for a few close binaries with known parallax and a dynamical mass determination, comparison of spectra to models is the only method

We triggered a Chandra ToO observation of the ongoing outburst of a transient source in the globular cluster Terzan 5 (ATel #2919, #2920, #2922, #2924, #2929, #2932, #2933, #2937, #2939, #2940, #2946, #2952, #2958). The 9.9 ks observation was taken with the ACIS S3 chip in imaging mode and began on 2010-10-24 at 19:30:29 UTC. Inspection of the new
