A star known by the unassuming name of KIC 8462852 in the constellation Cygnus has been raising eyebrows both in and outside of the scientific community for the past year. In 2015 a team of astronomer...

We present and analyse the deepest, high-quality Ks-band images ever obtained of luminous quasars at z~4, in an attempt to determine the basic properties of their host galaxies less than 1 Gyr after t...

We have made observations of the associated HI absorption of a
high redshift radio galaxy 0902C34 at z D 3:395 with the Giant Meterwave
Radio Telescope in the 3231MHz band.We find a narrowabsorptio...
Assuming that the disc of our Galaxy, the Milky Way, obeys the
classical exponential law, that it is maximal and the Sun is rather far from the
maximum of its circular velocity, one ¯nds that, ...
