In a previous article, we have reported on the first subpicometer interferometer flown in
space as part of ESA's LISA Pathfinder mission, and have shown the residual sensor noise …

With references to both key and often forgotten pioneering works, this article starts by
presenting a review into how we came to believe in the existence of massive black holes at …

In the months since the publication of the first results, the noise performance of LISA
Pathfinder has improved because of reduced Brownian noise due to the continued decrease …

We report the first results of the LISA Pathfinder in-flight experiment. The results demonstrate
that two free-falling reference test masses, such as those needed for a space-based …

Abstract DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) is the future
Japanese space gravitational wave antenna. The goal of DECIGO is to detect gravitational …

Several recent papers have reported on the occurrence of active galactic nuclei (AGNs)
containing undermassive black holes relative to a linear scaling relation between black hole …

Do the laws of quantum physics still hold for macroscopic objects-this is at the heart of
Schrödinger's cat paradox-or do gravitation or yet unknown effects set a limit for massive …

LISA Pathfinder (LPF) is a science and technology demonstrator planned by the European
Space Agency in view of the LISA mission. As a scientific payload, the LISA Technology …

The science operations of the LISA Pathfinder mission have demonstrated the feasibility of
sub-femto-g free fall of macroscopic test masses necessary to build a gravitational wave …

This paper presents a quantitative assessment of the performance of the upcoming LISA
Pathfinder geodesic explorer mission. The findings are based on the results of extensive …
