Constraining Dirty Black Holes and pseudo-complex General Relativity with the Gravitational Waves Transient Catalog 3.0
Yehu I. Maimon, Alex B. Nielsen, Ofek Birnholtz
We use data from the Gravitational Wave Transient Catalog 3.0 to update constraints on parameterized deviations from General Relativity, as encountered in pseudo-complex general re…

Black hole mimickers: from theory to observation
Cosimo Bambi, Ramy Brustein, Vitor Cardoso +16
The black hole paradigm, while remarkably successful, raises fundamental questions-both classical and quantum-about the nature of spacetime, horizons, and singularities. Black hole…

Possible Causes of False General Relativity Violations in Gravitational Wave Observations
Anuradha Gupta, K. G. Arun, Enrico Barausse +40
General relativity (GR) has proven to be a highly successful theory of gravity since its inception. The theory has thrivingly passed numerous experimental tests, predominantly in w…
