The search for a consistent theory of finite-range gravity is a longstanding problem and well motivated by both theoretical and observational considerations. On the theoretical side, whether there exists such a consistent extension of general relativity by a mass term is a basic question of classical field theory. After Fierz and Pauli's pioneering attempt in 1939, this issue has been...

With the successes of observational cosmology, a new window has opened up
on to gravitational physics. By carefuly measuring the morphology and growth
of structure in the Universe it may be possible to constrain general relativity on a
completely new range of scales. It also allows us to explore a plethora of modified
gravity theories that have emerged as an attempt to explain the...

I will review some of the recent progress and current status in the studies of two important modified gravity theories to explain the cosmic acceleration: Galileon gravity and f(R) gravity. I will discuss possible cosmological, astrophysical or terrestrial constraints on these, and other related, theories for the near future. Based on these, I will promote Galileon gravity as a competitive...

Inspiralling binaries of neutron stars and black holes are self-calibrating standard sirens whose observations can measure the luminosity distance without the need to make any complicated modelling of the sources. For binary neutron stars it is also possible to measure the source redshift from gravitational-wave observations alone. Together with joint observations of sources in both the...
