Gauge/gravity duality at the core

Gauge/gravity duality at the core Matter in the interior of neutron stars can reach densities several times larger than that of atomic nuclei. Properties of matter at such high densities can be constrained from astrophysical observations and gravitational-wave signals...

Recent results from CARMENES The CARMENES spectrograph is surveying around 300 M-dwarf stars to look for exoplanets. About 20 exoplanets have already been announced, and a number of candidates are still under analysis. These discoveries show that there is wider...

Inferring the dynamical growth of structures at high-redshift While the standard model of cosmology fits most cosmological observations to extraordinary accuracy, some tensions between the model and observations seem to persist despite the increasing quality of data....

Weak lensing with uncertain redshifts

by | Oct 16, 2019 | Events, Talk

Weak lensing with uncertain redshifts The cosmological conclusions of weak lensing surveys are very sensitive to the assumed redshift distributions of sources placed in different tomographic bins. In reality, these distributions are not known quantities, so from a...
