Simulating momentum exchange in the dark sector
No full textLow energy interactions between particles are often characterised by elastic
scattering. Just as electrons undergo Thomson scattering with photons, dark
matter particles may experience an analogous form of momentum exchange with
dark energy. We investigate the influence such an interaction has on the
formation of linear and nonlinear cosmic structure, by running for the first
time a suite of N-body simulations with different dark energy equations of
state and scattering cross sections. In models where the linear matter power
spectrum is suppressed by the scattering, we find that on nonlinear scales the
power spectrum is strongly enhanced. This is due to the friction term
increasing the efficiency of gravitational collapse, which also leads to a
scale-independent amplification of the concentration and mass functions of
halos. The opposite trend is found for models characterised by an increase of
the linear matter power spectrum normalisation. More quantitatively, we find
that power spectrum deviations at nonlinear scales (Mpc) are
roughly ten times larger than their linear counterparts, exceeding for
the largest value of the scattering cross section considered in the present
work. Similarly, the concentration-mass relation and the halo mass function
show deviations up to and , respectively, over a wide range of
masses. Therefore, we conclude that nonlinear probes of structure formation
might provide much tighter constraints on the scattering cross section between
dark energy and dark matter as compared to the present bounds based on linear
observables
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
