Gravitational waves have opened a new observational window through which some of the most exotic objects in the Universe, as well as some of the secrets of gravitation itself, can now be revealed. Among all these new discoveries, we recently demonstrated [N. Tamanini & C. Danielski, Nat. Astron., 3(9), 858 (2019)] that space-based gravitational wave observations will have the potential to detect a new population of massive circumbinary exoplanets everywhere inside our Galaxy. In this essay we… Expand

Probing the nature of black holes: Deep in the mHz gravitational-wave sky
Precision tests of black hole spacetimes with mHz-band gravitational-wave detectors will probe general relativity and fundamental physics in previously inaccessible regimes, and allow us to address some of these fundamental issues in the current understanding of nature. Expand
Milky Way Satellites Shining Bright in Gravitational Waves
The population of Milky Way satellite galaxies is of great interest for cosmology, fundamental physics, and astrophysics. They represent the faint end of the galaxy luminosity function, are the mostExpand
Probing Planets in Extragalactic Galaxies Using Quasar Microlensing.
Previously, planets have been detected only in the Milky Way galaxy. Here, we show that quasar microlensing provides a means to probe extragalactic planets in the lens galaxy, by studying theExpand
Black holes, gravitational waves and fundamental physics: a roadmap
The grand challenges of contemporary fundamental physics—dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem—all involve gravityExpand
Cosmological backgrounds of gravitational waves
Gravitational wave observations have a great potential for probing cosmology. Here we concentrate on the early universe, and review proposed sources that can lead to cosmological backgrounds ofExpand
The gravitational-wave detection of exoplanets orbiting white dwarf binaries using LISA
So far, around 4,000 exoplanets have been discovered orbiting a large variety of stars. Owing to the sensitivity limits of the currently used detection techniques, these planets populate zonesExpand
Laser Interferometer Space Antenna
Following the selection of The Gravitational Universe by ESA, and the successful flight of LISA Pathfinder, the LISA Consortium now proposes a 4 year mission in response to ESA's call for missionsExpand
Unveiling the gravitational universe at μ-Hz frequencies
We propose a space-based interferometer surveying the gravitational wave (GW) sky in the milli-Hz to μ-Hz frequency range. By the 2040s, the μ-Hz frequency band, bracketed in between the LaserExpand
Predicting the LISA white dwarf binary population in the Milky Way with cosmological simulations
White dwarf binaries with orbital periods below 1 h will be the most numerous sources for the space-based gravitational wave detector Laser Interferometer Space Antenna (LISA). Based on thousandsExpand
Detecting hierarchical stellar systems with LISA
A significant fraction of stars are members of gravitationally bound hierarchies containing three or more components. Almost all low-mass stars in binaries with periods shorter than three days areExpand
