Euclid: The reduced shear approximation and magnification bias for Stage IV cosmic shear experiments?
(EDP Sciences, 2020)
Context. Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordingly, previously ignored systematic ...
CP-strong problem and U(1)' non-universal symmetry
(Departamento de FísicaUniversidad Nacional de Colombia - Sede Bogotá, 2019-07-19)
We present a non-universal U (1)X extension and an additional global anomala Peccei-Quinn (PQ) symmetry to the standard model (SM). The scheme proposed allow us to distinguish among fermion families without introducing ...
Chandra/Very Large Array follow-Up of TeV J2032+4131, the only unidentified TeV gamma-ray source
(IOP Publishing, 2003-12)
The High Energy Gamma Ray Astronomy (HEGRA) Cerenkov telescope array group recently reported a steady and extended unidentified TeV gamma-ray source lying at the outskirts of Cygnus OB2. This is the most massive stellar ...
The Gaia-ESO Survey: detection and characterisation of single-line spectroscopic binaries
(European Southern Observatory, 2020)
Context. Multiple stellar systems play a fundamental role in the formation and evolution of stellar populations in galaxies. Recent and ongoing large ground-based multi-object spectroscopic surveys significantly increase ...
A translucent interstellar cloud at z = 2.69. CO, H2, and HD in the line-of-sight to SDSS J123714.60+064759.5
(2010)
We present the analysis of a sub-damped Lyman-α system with neutral hydrogen column density, log N(H0) (cm-2) = 20.0 ± 0.15 at zabs = 2.69 toward SDSS J123714.60 + 064759.5 (zem = 2.78). Using the VLT/UVES and X-shooter ...
Distinguishing circumstellar from stellar photometric variability in Eta Carinae
(Oxford University Press, 2019-03)
The interacting binary Eta Carinae remains one of the most enigmatic massive stars in our Galaxy despite over four centuries of observations. In this work, its light curve from the ultraviolet to the near-infrared is ...
Detecção de neutrinos no observatório Pierre Auger
(Universidade Estadual Paulista (Unesp), 2003-03)
Faz-se aqui o estudo da detecção de neutrinos (v) de altas energias ('E IND.v' > '10 POT.9' GeV) no Observatório Pierre Auger usando os detectores de fluorescência. Introduzimos todo o conhecimento experimental dos raios ...
The future of (non-)global governance
(2017)
The title of this paper sounds preposterous, and indeed is. There are many reasons for this qualification and, pre-empting criticisms, I mention three main ones. The first is that any exercise in futurology bears a touch ...
