Dark energy loopholes some time after GW170817 (2020)
Journal Article
Bordin, L., Copeland, E. J., & Padilla, A. (2020). Dark energy loopholes some time after GW170817. Journal of Cosmology and Astroparticle Physics, 2020(11), Article 063. https://doi.org/10.1088/1475-7516/2020/11/063

We revisit the constraints on scalar tensor theories of modified gravity following the purge of GW170817. We pay particular attention to dynamical loopholes where the anomalous speed of propagation of the gravitational wave can vanish on-shell, when...

Probing higher-spin fields from inflation with higher-order statistics of the CMB (2019)
Journal Article
Bordin, L., & Cabass, G. (2019). Probing higher-spin fields from inflation with higher-order statistics of the CMB. Journal of Cosmology and Astroparticle Physics, 2019(June), https://doi.org/10.1088/1475-7516/2019/06/050

We investigate the degree to which the Cosmic Microwave Background (CMB) can be used to constrain primordial non-Gaussianity coming from the presence of spinning particles coupled to the inflaton. We compute the TTT and TTTT correlation funct... Read More about Probing higher-spin fields from inflation with higher-order statistics of the CMB.
