We present a comprehensive study of the thermonuclear bursts and millihertz quasi-periodic oscillations (mHz QPOs) from the neutron star (NS) transient and 11 Hz X-ray pulsar IGR J17480-2446, located in the globular cluster Terzan 5. The increase in burst rate that we found during its 2010 outburst, when persistent luminosity rose from 0.1 to 0.5

We present measurements of the mean mid-infrared to submillimetre flux densities of massive (M★≳ 1011 M&sun;) galaxies at redshifts 1.7 z 2.9, obtained by stacking positions of known objects taken from the GOODS NICMOS Survey (GNS) catalogue on maps at 24 ?m (Spitzer/MIPS); 70, 100 and 160 ?m (Herschel/PACS); 250, 350 and 500 ?m (BLAST); and 870

A logarithmic spiral is a prominent feature appearing in a majority of observed galaxies. This feature has long been associated with the traditional Hubble classification scheme, but historical quotes of pitch angle of spiral galaxies have been almost exclusively qualitative. We have developed a methodology, utilizing two-dimensional fast Fourier

MarcoPolo-R is a sample return mission to a primitive Near-Earth Asteroid (NEA) proposed in collaboration with NASA. It will rendezvous with a primitive NEA, scientifically characterize it at multiple scales, and return a unique sample to Earth unaltered by the atmospheric entry process or terrestrial weathering. MarcoPolo-R will return bulk

Local concentrations of PM10 are affected on the one hand by the extent of natural and anthropogenic emissions of these air pollutants and as well by the level of precursor emissions. On the other hand local meteorological conditions and large scale circulation dynamics are important additional influencing factors. Whereas the general relationship
