Dipolar power asymmetry in wide-angle correlations of galaxy density, velocity and ellipticity
Yusuke Mikura, Teppei Okumura, Ippei Obata +1
The large-scale structure of the universe has the potential to probe anomalies suggested by observations of the cosmic microwave background. In this work, we focus on a position-de…
Imprints of gravitational-wave polarizations on projected tidal tensor in three dimensions
Yusuke Mikura, Teppei Okumura, Misao Sasaki
Gravitational waves (GWs) distort galaxy shapes through the tidal effect, offering a novel avenue to probe the nature of gravity. In this paper, we investigate how extra GW polariz…
Some simple theories of gravity with propagating nonmetricity
Yusuke Mikura, Roberto Percacci
We investigate symmetric Metric-Affine Theories of Gravity with a Lagrangian containing all operators of dimension up to four that are relevant to free propagation in flat space. C…
Some simple theories of gravity with propagating torsion
Yusuke Mikura, Vincenzo Naso, Roberto Percacci
We consider antisymmetric Metric-Affine Theories of Gravity with a Lagrangian containing the most general terms up to dimension four and search for theories that are ghost- and tac…
