Constraining a late time transition of Geff using low-z galaxy survey data
Original language description
It has recently been pointed out that a gravitational transition taking place at a recent redshift ztzt, reducing the effective gravitational constant GeffGeff by about 10%10% for z>ztz>zt, has the potential to lead to a resolution of the Hubble tension if zt≲0.01zt≲0.01. Since H(z)2∼GeffH(z)2∼Geff, such a transition would also lead to sharp change of the slope of the Hubble diagram at z=ztz=zt and a sharp decrease in the number of galaxies per redshift bin at ztzt. Here we attempt to impose constraints on such a transition by using two robust low-z redshift survey datasets (z<0.01z<0.01), taken from the Six-degree Field Galaxy Survey (6dFGS) as well as the 2MASS Redshift Survey (2MRS). In both surveys, we bin the data in redshift bins and focus on the number of galaxies in each bin (ΔN(zi)ΔN(zi)).
