2D Surface Brightness Modelling of Large 2MASS Galaxies II: The Role of Classical Bulges and Pseudobulges on Galaxy Scaling Relations and its implication for Supermassive Black Hole Formation
Emmanuel Ríos-López, Omar López-Cruz, Christopher Añorve +3
We have generated 2D-multicomponent surface brightness (SB) modelling for 100 galaxies in the Large Galaxy Atlas (LGA) together with 19 nearby cD galaxies using the near-infrared (…

Revisiting Einstein's analogy: black holes as gradient-index lenses
J. E. Gómez-Correa, E. Espíndola-Ramos, O. López-Cruz +1
According to Albert Einstein, gravitation is analogous to an optical medium. Building on this idea, various definitions of the gradient-index (GRIN) medium representing curved spac…
