Evidence for interacting dark energy from BOSS
Elisa G. M. Ferreira, Jerome Quintin, André A. Costa +2
The result presented by the BOSS-SDSS Collaboration measuring the baryon acoustic oscillations of the Lyman- forest from high-redshift quasars indicates a departure from…
Quintessence with Yukawa Interaction
André A. Costa, Lucas C. Olivari, E. Abdalla
We consider a quintessence model for dark energy interacting with dark matter via a Yukawa interaction. To put constraints on this model we use the CMB measurements from the Planck…
Scalar fields in the Lense-Thirring background with a cosmic string and Hawking radiation
H. S. Vieira, V. B. Bezerra, André A. Costa
We analyze the influence of the gravitational field produced by a slowly rotating black hole with a cosmic string along the axis of symmetry on a massive scalar field. Exact soluti…
