  author={Michael A. Fedderke and Peter W. Graham and Bruce A. Macintosh and Surjeet Rajendran},
We evaluate the potential for gravitational-wave (GW) detection in the frequency band from 10 nHz to 1 µ Hz using extremely high-precision astrometry of a small number of stars. In particular, we argue that non-magnetic, photometrically stable, hot white dwarfs (WD) located at ∼ kpc distances may be optimal targets for this approach. Previous studies of astrometric GW detection have focused on the potential for less precise surveys of large numbers of stars; our work provides an alternative…

Using Pulsar Parameter Drifts to Detect Sub-Nanohertz Gravitational Waves

Gravitational waves with frequencies below 1 nHz are notoriously difficult to detect. With periods exceeding current experimental lifetimes, they induce slow drifts in observables rather than periodic

Searching for dark clumps with gravitational-wave detectors

Dark compact objects (“clumps”) transiting the Solar System exert accelerations on the test masses (TM) in a gravitational-wave (GW) detector. We reexamine the detectability of these clump transits

Asteroids for ultralight dark-photon dark-matter detection

Gravitational-wave (GW) detectors that monitor fluctuations in the separation between inertial test masses (TMs) are sensitive to new forces acting on those TMs. Ultralight dark-photon dark matter

Gravitational wave detection with photometric surveys

Gravitational wave (GW) detections have considerably enriched our understanding of the universe. To date, all the known events were observed via direct detection. In this paper, we study a GW

Astrometric effects of a stochastic gravitational wave background

A stochastic gravitational wave background causes the apparent positions of distant sources to fluctuate, with angular deflections of order the characteristic strain amplitude of the gravitational

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 Laser

Multiwavelength Mitigation of Stellar Activity in Astrometric Planet Detection

Astrometry has long been a promising technique for exoplanet detection. At the theoretical limits, astrometry would allow for the detection of smaller planets than previously seen by current

Space Based Gravitational Wave Astronomy Beyond LISA

The Laser Interferometer Space Antenna (LISA) will open three decades of gravitational wave (GW) spectrum between 0.1 and 100 mHz, the mHz band. This band is expected to be the richest part of the GW

Halometry from astrometry

Halometry—mapping out the spectrum, location, and kinematics of nonluminous structures inside the Galactic halo—can be realized via variable weak gravitational lensing of the apparent motions of

Power of halometry

Astrometric weak gravitational lensing is a powerful probe of the distribution of matter on sub-Galactic scales, which harbor important information about the fundamental nature of dark matter. We

Astrometric Search Method for Individually Resolvable Gravitational Wave Sources with Gaia.

This technique was successfully used to recover artificially injected GW signals from mock Gaia data and to assess the GW sensitivity of Gaia, and the complementarity of Gaia and pulsar timing searches for GWs is highlighted.

GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral

On August 17, 2017 at 12 ∶ 41:04 UTC the Advanced LIGO and Advanced Virgo gravitational-wave detectors made their first observation of a binary neutron star inspiral. The signal, GW170817, was


Analytical relations are derived for the amplitude of astrometric, photometric, and radial velocity (RV) perturbations caused by a single rotating spot. The relative power of the starspot jitter is
