Comparative Study of Early-Universe Epochs in an $f (R, L_{m})$ Gravity Model with Effective Curvature--Matter Interaction and $I^$ CDM Cosmology

G. K. Goswami, J. P. Saini

We investigate a specific gravity model of the form $f (R, L_{m}) = I^\pm R + L_{m}^{2} + I^^{3}$ , where the nonlinear dependence on the matter Lagrangian $L_{m}$ introduces an effective curvature…

Growth Rate Analysis in $f (R, L_{m})$ Gravity: A Comparative Study with \boldmath $I^$ CDM Cosmology

G. K. Goswami, J. P. Saini

We investigate the evolution of cosmic structures within the framework of modified gravity, specifically focusing on theories described by the function $f (R, L_{m})$ , where $R$ is th…

Self-interactions of ultralight spinless dark matter to the rescue?

Gaurav Goswami

Numerous observations on astrophysical and cosmological scales can be interpreted to mean that, in addition to the familiar kind of matter well described by the standard model of e…
