Pulsar timing array sensitivity to anisotropies in the gravitational wave background
Paul Frederik Depta, Valerie Domcke, Gabriele Franciolini +1
Pulsar Timing Array (PTA) observations have recently gathered substantial evidence for the existence of a gravitational wave background in the nHz frequency band. Searching for ani…
Does NANOGrav observe a dark sector phase transition?
Torsten Bringmann, Paul Frederik Depta, Thomas Konstandin +2
Gravitational waves from a first-order cosmological phase transition, at temperatures at the MeV-scale, would arguably be the most exciting explanation of the common red spectrum r…
Signals of merging supermassive primordial black holes in pulsar timing arrays
Paul Frederik Depta, Kai Schmidt-Hoberg, Pedro Schwaller +1
In this work we evaluate whether the gravitational wave background recently observed by a number of different pulsar timing arrays could be due to merging primordial supermassive b…
Strong constraints on clustered primordial black holes as dark matter
Torsten Bringmann, Paul Frederik Depta, Valerie Domcke +1
The idea of dark matter in the form of primordial black holes has seen a recent revival triggered by the LIGO detection of gravitational waves from binary black hole mergers. In th…
