In this compilation, the theory of gravitational anti-screening is
presented as an alternative to the current theory of dark matter.
This includes first applying the theory to the rotational curve of
the galaxy, to spiral galaxies in general, and to the Coma cluster.
Finally, the theory will be applied to the solar system where it
will be shown to be compatible with planetary ephemerides. Next,
the observable features that allow for the reconstruction of past
environmental conditions are collected and characterized, focusing
on the available data, uncertainties, missing information and
targets of future research work. Furthermore, mineral paragenesis
and different types of indicators should be used in conjunction and
the missing data represents the directions for future research. The
following chapter presents the evaluation of some aspects of the
two remaining landing site candidates (Oxia Planum and Mawrth
Vallis) for the ESA ExoMars 2020 rover to highlight the geological
and astrobiological aspects. These lessons learned should be used
in the future to support the scientific outcome. Discussion
continues about the nature of the zebrastructure in type IV radio
bursts, proposing that even the most protracted mechanism
associated with double plasma resonance has been improved in a
series of works. The authors demonstrate the possibility of
modeling with whistlers to explain many thin components of
zebrastructure stripes, taking into account the effects of
scattering whistlers on fast particles. The existence of Dark
Matter in the Universe is one of the most accepted ideas in modern
cosmology to explain a number of puzzling astronomical
observations, even though it has not been directly observed. As
such, the authors review the motivation for its existence as
inferred from its influence on ordinary matter and its properties
in terms of specific candidate particles. Broad-lined type Ic
supernovae (SNe Ic-BL) have received much attention as of late
because they are the only SNe associated with long-duration
gamma-ray bursts. In this book, efforts have been made to
understand the origin of their huge kinetic energy, peculiar light
curve, and spectral features. Lastly, three hygroscopic salts are
discussed, calcium perchlorate (Ca(ClO4)2), magnesium perchlorate
(Mg(ClO4)2) and calcium chloride (CaCl2). Examination of past rover
landing sites showed that at most of them deliquescence could occur
in theory, based on the modeled meteorological values and assuming
that hygroscopic salts are at hand.
