1. Gravitational Rainbows: LIGO and Dark Energy at its Cutoff / de Rham, Claudia ; Melville, Scott
The recent direct detection of gravitational waves from a neutron star merger with optical counterpart has been used to severely constrain models of dark energy that typically predict a modification of the gravitational wave speed. [...]

2. Improved positivity bounds and massive gravity / Rham, Claudia ; Melville, Scott ; Tolley, Andrew
Theories such as massive Galileons and massive gravity can satisfy the presently known improved positivity bounds provided they are weakly coupled. [...]

3. UV complete me: positivity bounds for particles with spin / Rham, Claudia ; Melville, Scott ; Tolley, Andrew ; Zhou, Shuang-Yong
For a low energy effective theory to admit a standard local, unitary, analytic and Lorentz-invariant UV completion, its scattering amplitudes must satisfy certain inequalities. [...]

4. Massive Galileon positivity bounds / Rham, Claudia ; Melville, Scott ; Tolley, Andrew ; Zhou, Shuang-Yong
The EFT coefficients in any gapped, scalar, Lorentz invariant field theory must satisfy positivity requirements if there is to exist a local, analytic Wilsonian UV completion. [...]

6. The coupling to matter in massive, bi- and multi-gravity / Noller, Johannes ; Melville, Scott
In this paper we construct a family of ways in which matter can couple to one or more `metrics'/spin-2 fields in the vielbein formulation [...]
