Abstract: We present deep, wide-field imaging of the Globular Cluster NGC 5024, obtained at the Large Binocular Telescope. Images in U, B and V were obtained with the Large Binocular Camera, allowing to resolve the stars down to U ∼25.5 in a field of view of 25′ × 24′ . The combination of short and deep exposures allowed the construction of color-magnitude diagrams spanning all the canonical sequences from the tip of the red giant brunch down to 4 magnitudes below the main sequence Turn Off. Combining this data with high resolution ACS@HST archive images of the central region of the cluster we selected a well defined population of blue stragglers stars, confirming that they have a bimodal radial distribution. Moreover we determined the binary frequency in the outer regions (r > 200′′) of the cluster, finding that about 14% of the stars in these regions are in binary systems.

TL;DR: In this article, the authors presented foreground-reduced cosmic microwave background (CMB) maps derived from the full Planck data set in both temperature and polarization, and compared to the corresponding Planck 2013 temperature sky maps, the total data volume is larger by a factor of 3.

TL;DR: In this paper, the results of approximately three years of observations of Planck Sunyaev-Zeldovich (SZ) sources with the Russian-Turkish 1.5 m telescope (RTT150) are presented.

TL;DR: The status of the mission is presented in the light of the design solutions adopted by the contractors, and the performances of the spacecraft in its operation, the telescope assembly, the scientific instruments as well as the data-processing have been carefully budgeted to meet the demanding scientific requirements.
