Advances on GRB as cosmological tools [PDF]

open access: yes, 2009
Several interesting correlations among Gamma Ray Bursts (GRB) prompt and afterglow properties have been found in the recent years. Some of these correlations have been proposed also to standardize GRB energetics to use them as standard candles in ...

Relativistic MOND from Modified Energetics [PDF]

open access: yes, 2014
We begin to investigate the question of what modifications in energy-momentum tensor can yield correct MOND regime. As a starting study, we refrain from insisting on an action principle and focus exclusively on the equations of motion.
