  In a series of works by two of us, various characteristics of the glasma from
the earliest phase of relativistic heavy-ion collisions have been studied using
a proper time expansion. These characteristics include: energy density,
longitudinal and transverse pressures, collective flow, angular momentum and
parameters of jet quenching. In this paper we extend the proper time interval
where our results are reliable by working at higher order in the expansion. We
also generalize our previous study of jet quenching by extending our
calculations to consider inhomogeneous glasma. Inhomogeneities are an important
aspect of physically realistic systems that are difficult to include in
calculations and are frequently ignored.
