In the recent years, primordial black holes (PBHs) have emerged as one of the most
interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could …

It is possible that primordial black holes (PBHs) constitute (or constituted) a significant
fraction of the energy budget of our Universe. Terrestrial gravitational wave detectors offer …

Gravitational waves (GWs) generate oscillating electromagnetic effects in the vicinity of
external electric and magnetic fields. We discuss this phenomenon with a particular focus on …

Light primordial black holes may comprise a dominant fraction of the dark matter in our
Universe. This paper critically assesses whether planned and future gravitational wave …

Superconducting cavities can operate analogously to Weber bar detectors of gravitational
waves, converting mechanical to electromagnetic energy. The significantly reduced …

We revisit a question asked by Dyson:“Is a graviton detectable?” We demonstrate that in
both Dyson's original sense and in a more modern measurement-theoretic sense, it is …

In the post-LIGO era, there has been a lot of focus on primordial black holes (PBHs) heavier
than∼ 10 15 g as potential dark matter (DM) candidates. We point out that the branch of the …

High-frequency gravitational waves (HFGWs) are predicted in various exotic scenarios
involving both cosmological and astrophysical sources. These elusive signals have recently …

High frequency gravitational waves can be detected by observing the frequency modulation
they impart on photons. We discuss fundamental limitations to this method related to the fact …

Gravitational waves (GWs) in the MHz–GHz frequency range are motivated by a host of early
Universe phenomena such as oscillons, preheating, and cosmic strings. We point out that …
