1. Hearing without seeing: gravitational waves from hot and cold hidden sectors / Fairbairn, Malcolm ; Hardy, Edward ; Wickens, Alastair
We study the spectrum of gravitational waves produced by a first order phase transition in a hidden sector that is colder than the visible sector. [...]

2. Gravitationally produced top quarks and the stability of the electroweak vacuum during inflation / Rodriguez Roman, David ; Fairbairn, Malcolm
In the standard model the (Brout-Englert-)Higgs quartic coupling becomes negative at high energies rendering our current electroweak vacuum metastable, but with an instability timescale much longer than the age of the current universe. [...]

3. Simple no-scale model of modulus fixing and inflation / Ellis, John ; Fairbairn, Malcolm ; Romano, Antonio Enea ; Zapata, Óscar
We construct a no-scale model of inflation with a single modulus whose real and imaginary parts are fixed by simple power-law corrections to the no-scale Kähler potential. [...]

4. Detecting fluorescent dark matter with X-ray lasers / Day, Francesca ; Fairbairn, Malcolm
Fluorescent dark matter has been suggested as a possible explanation of both the 3.5 keV excess in the diffuse emission of the Perseus Cluster and of the deficit at the same energy in the central active galaxy within that cluster, NGC 1275. [...]

5. Horizon feedback inflation / Fairbairn, Malcolm ; Markkanen, Tommi ; Rodriguez Roman, David
We consider the effect of the Gibbons–Hawking radiation on the inflaton in the situation where it is coupled to a large number of spectator fields. [...]

6. Anomaly-free models for flavour anomalies / Ellis, John ; Fairbairn, Malcolm ; Tunney, Patrick
We explore the constraints imposed by the cancellation of triangle anomalies on models in which the flavour anomalies reported by LHCb and other experiments are due to an extra U(1) ′ gauge boson Z ′ . [...]

7. Anomaly-free dark matter models are not so simple / Ellis, John ; Fairbairn, Malcolm ; Tunney, Patrick
We explore the anomaly-cancellation constraints on simplified dark matter (DM) models with an extra U(1) ′ gauge boson Z ′ . [...]

8. Glueball dark matter in non-standard cosmologies / Acharya, Bobby ; Fairbairn, Malcolm ; Hardy, Edward
Hidden sector glueball dark matter is well motivated by string theory, compactifications of which often have extra gauge groups uncoupled to the visible sector. [...]

9. Erratum to: Physics from solar neutrinos in dark matter direct detection experiments / Cerdeño, David ; Fairbairn, Malcolm ; Jubb, Thomas ; Machado, Pedro ; et al
We correct 1) missing factors of 2 in cross section expressions in table 4 of the published article; and 2) the LUX bound in figure 6 on the B-L coupling from 2015 data, which displayed erroneously strong constraints due to a computer error. [...]

10. Constraints on Z ′ models from LHC dijet searches and implications for dark matter / Fairbairn, Malcolm ; Heal, John ; Kahlhoefer, Felix ; Tunney, Patrick
We analyse a combination of ATLAS and CMS searches for dijet resonances at run I and run II, presenting the results in a way that can be easily applied to a generic Z ′ model. [...]
