Hamburg Observatory

Every year, University of Hamburg welcomes many new researchers. Here, we present part of a series to introduce them and their areas of research. This time: cosmologist Luisa Lucie-Smith.

A team of scientists using the eROSITA X-ray telescope has shed light on one of the most elusive components of the universe: the warm-hot intergalactic medium (WHIM). This ‘ghost’ form of ordinary matter, long hypothesized but rarely detected, is thought to account for a significant portion of the universe's missing...

Which clumps of interstellar gas will collapse under gravity to form stars and which clumps will not? This is related to a key problem in turbulence: to understand the distribution of densities produced. Using simulations and analytic work, researchers have been able to both track and model the evolution of densities under...
