    A Time Delay for the Largest Gravitationally Lensed Quasar: SDSS J1004+4112 by Fohlmeister, J, Kochanek, C, Falco, E, Wambsganss, J, Morgan, N, Morgan, C, Ofek, E, Maoz, D, Keeton, C, Barentine, J, Dalton, G, Dembicky, J, Ketzeback, W, McMillan, R, Peters, C

    Published 2006
    “…We present 426 epochs of optical monitoring data spanning 1000 days from December 2003 to June 2006 for the gravitationally lensed quasar SDSS J1004+4112. The time delay between the A and B images is 38.4+/-2.0 days in the expected sense that B leads A and the overall time ordering is C-B-A-D-E. …”

    Gravitational lensing by charged black hole in regularized 4D Einstein–Gauss–Bonnet gravity by Rahul Kumar, Shafqat Ul Islam, Sushant G. Ghosh

    Published 2020-12-01
    “…Recently there has been a surge of interest in regularizing, a $$ D \rightarrow 4 $$ D → 4 limit of, the EGB gravity, and the resulting regularized 4D EGB gravity valid in 4D. We consider gravitational lensing by Charged black holes in the 4D EGB gravity theory to calculate the light deflection coefficients in strong-field limits $$\bar{a}$$ a ¯ and $$\bar{b}$$ b ¯ , while former increases with increasing GB parameter $$\alpha $$ α and charge q, later decrease. …”
