On the Green and Wald formalism
Jan J. Ostrowski, Boudewijn F. Roukema
Backreaction in the cosmological context is a longstanding problem that is especially important in the present era of precise cosmology. The standard model of a homogeneous backgro…
Is the baryon acoustic oscillation peak a cosmological standard ruler?
Boudewijn F. Roukema, Thomas Buchert, Hirokazu Fujii +1
In the standard model of cosmology, the Universe is static in comoving coordinates; expansion occurs homogeneously and is represented by a global scale factor. The baryon acoustic…
Is there proof that backreaction of inhomogeneities is irrelevant in cosmology?
T. Buchert, M. Carfora, G. F. R. Ellis +8
No. In a number of papers Green and Wald argue that the standard FLRW model approximates our Universe extremely well on all scales, except close to strong field astrophysical objec…
