Testing screened modified gravity with SDSS-IV-MaNGA
Ricardo G. Landim, Harry Desmond, Kazuya Koyama +1
Fifth forces are ubiquitous in modified gravity theories, and must be screened to evade stringent local tests. This can introduce unusual behaviour in galaxy phenomenology by affec…

The BINGO radiotelescope will observe hydrogen distribution using Intensity Mapping (IM) to analyze the Dark Energy paradigm through Baryon Acoustic Oscillations. The target signal…
The BINGO project VIII: On the recoverability of the BAO signal on HI intensity mapping simulations
Camila Paiva Novaes, Jiajun Zhang, Eduardo J. de Mericia +17
A new and promising technique for observing the Universe and study the dark sector is the intensity mapping of the redshifted 21cm line of neutral hydrogen (HI). The BINGO radio te…
A note on interacting holographic dark energy with a Hubble-scale cutoff
Ricardo G. Landim
Holographic dark energy with the Hubble radius as infrared cutoff has been considered as a candidate to explain the late-time cosmic acceleration and it can solve the coincidence p…
Testing synchrotron models and frequency resolution in BINGO 21 cm simulated maps using GNILC
