In search for the furthest galaxies

teaserAn international research team is performing a program in search for the furthest galaxies in the universe. But distant objects are also very faint. For this reason, the search relies upon one of the strangest implications of general relativity: the amplification of light coming from remote bodies due to the gravitational effects of closer ones, the gravitational lensing effect. Calar Alto telescopes and instruments are contributing to this research…
