We identify a largely model-independent signature of dark matter (DM) interactions with
nucleons and electrons. DM in the local galactic halo, gravitationally accelerated to over half …

We investigate the capability of various configurations of the space interferometer eLISA to
probe the late-time background expansion of the universe using gravitational wave standard …

Taiji, a space-based gravitational-wave observatory, consists of three satellites forming an
equilateral triangle with arm length of 3× 10 6 km, orbiting around the Sun. Taiji is able to …

Abstract The upcoming Laser Interferometer Space Antenna (LISA), set for launch in the mid-
2030s, will enhance our capability to probe the universe through gravitational waves (GWs) …

An intermediate-mass black hole (IMBH) was recently reported to reside in the centre of the
Galactic globular cluster (GC) NGC 6624, based on timing observations of a millisecond …

We demonstrate the ability of existing and planned telescopes, on the ground and in space,
to directly image tidally heated exomoons orbiting gas-giant exoplanets. Tidally heated …

Extremely Large Telescopes are making Pyramid Wavefront Sensors (PWFS) the preferred
engineering choice for Adaptive Optics designs, such as the MICADO camera SCAO …

Adaptive Optics (AO) systems in large telescopes do not only correct atmospheric phase
disturbances, but they also telescope structure vibrations induced by wind or telescope …

The imaging and spectroscopy of habitable worlds will require large-aperture space-based
telescopes, to increase the collecting area and the angular resolution. These large …

High-contrast imaging and spectroscopy provide unique constraints for exoplanet formation
models as well as for planetary atmosphere models. Instrumentation techniques in this field …
