Euclid: Forecast constraints on the cosmic distance duality relation with complementary external probes (2020)
Journal Article
Martinelli, M., Martins, C., Nesseris, S., Sapone, D., Tutusaus, I., Avgoustidis, A., …Zacchei, A. (2020). Euclid: Forecast constraints on the cosmic distance duality relation with complementary external probes. Astronomy and Astrophysics, 644, Article A80. https://doi.org/10.1051/0004-6361/202039078

In metric theories of gravity with photon number conservation, the luminosity and angular diameter distances are related via the Etherington relation, also known as the distance-duality relation (DDR). A violation of this relation would rule out the... Read More about Euclid: Forecast constraints on the cosmic distance duality relation with complementary external probes.

Understanding the suppression of structure formation from dark matter-dark energy momentum coupling (2020)
Journal Article
Chamings, F. N., Avgoustidis, A., Copeland, E. J., Green, A. M., & Pourtsidou, A. (2020). Understanding the suppression of structure formation from dark matter-dark energy momentum coupling. Physical Review D, 101(4), https://doi.org/10.1103/physrevd.101.043531

Models in which scalar field dark energy interacts with dark matter via a pure momentum coupling have previously been found to potentially ease the structure formation tension between early-and late-universe observations. In this article we explore t... Read More about Understanding the suppression of structure formation from dark matter-dark energy momentum coupling.
