Analytical solutions of accreting black holes immersed in a Lambda CDM model
(ELSEVIER SCIENCE BV, 2010)
The evolution of the mass of a black hole embedded in a universe filled with dark energy and cold dark matter is calculated in a closed form within a test fluid model in a Schwarzschild metric, taking into account the ...
Non-adiabatic perturbations in decaying vacuum cosmology
(2011)
We investigate a spatially flat Friedmann-Lemaˆıtre-Robertson-Walker cosmology
in which a decaying vacuum term causes matter production at late times. Assuming a
decay proportional to the Hubble rate, the ratio of the ...
Electroweak symmetric dark matter balls
(Springer, 2019-09-02)
In the simple Higgs-portal dark matter model with a conserved dark matter number, we show that there exists a non-topological soliton state of dark matter. This state has smaller energy per dark matter number than a free ...

Deep Web and Dark Web: similarities and dissiparities in the context of Information Science
(Pontificia Universidade Catolica Campinas, 2020-01-01)
In this article, we aim to demystify the Deep Web and the Dark Web, in addition to presenting the main similarities and disparities between them, essentially in regard to their: (1)Term; (2) Definition; (3) Metaphorical ...

Analytic study of cosmological perturbations in a unified model of dark matter and dark energy with a sharp transition
(Elsevier B.V., 2018-12-01)
We study cosmological perturbations in a model of unified dark matter and dark energy with a sharp transition in the late-time universe. The dark sector is described by a dark fluid which evolves from an early stage at ...
