Ultra Light Axionic Dark Matter: Galactic Halos and Implications for Observations with Pulsar Timing Arrays
(MDPI, 2018-01-16)
The cold dark matter (CDM) paradigm successfully explains the cosmic structure over an enormous span of redshifts. However, it fails when probing the innermost regions of dark matter halos and the properties of the Milky ...
Mapping the cosmological expansion
(2019-04-09)
En esta tesis se usan observaciones geométricas del universo para poner a prueba la viabilidad demodelos cosmológicos que describen la expansión acelerada del universo y restringir así el espacio deparámetros de dichos ...
Characterization of (asymptotically) Kerr–de Sitter-like spacetimes at null infinity*
(IOP Publishing, 2016-08-04)
We investigate solutions(M, g) to Einstein's vacuum field equations with positive cosmological constant. which admit a smooth past null infinity J(-) a la Penrose and a Killing vector field whose associated Mars-Simon ...
Entanglement and extreme spin squeezing of unpolarized states
(IOP Publishing, 2017-01-20)
We present criteria to detect the depth of entanglement in macroscopic ensembles of spin-j particles using the variance and second moments of the collective spin components. The class of states detected goes beyond traditional ...
Erizaintza-prozesua: Gipuzkoako herrialdean izaniko erabileraren bilakaera
(2012-05-14)
Ameriketako Estatu Batuetan eta Kanadan 1950. urteetan sortu ostean, erizaintza-prozesua, egun, mundu osoko erizaintza-eskoletan, ospitaletan eta zentrotan erabiltzen da. Doktore-tesi honetan erizaintza-prozesuak Gipuzkoako ...
Implementation of the nursing process in a health area: models and assessment structures used
(Univ Sao Paulo, Escola de Enfermagem de Ribeirao Preto, 2014-09)
Objective: to analyze what nursing models and nursing assessment structures have been used in the implementation of the nursing process at the public and private centers in the health area Gipuzkoa (Basque Country). Method: ...
Eremu-teorien eta eredu analitikoen bidezko defektu kosmikoen ezaugarritzea
(2017-05-12)
Kosmologiaren eredu estandarraren eta partikulen eredu estandarraren arteko zubi-lana egiteko hautagai interesgarrienetakoak defektu kosmikoak dira. Ondorioz, defektu kosmiko hauen ezaugarritze zehatzak berebiziko garrantzia ...
Anomalous transport in second order hydrodynamics
(E. D. P Sciences, 2016)
We study the non-dissipative transport effects appearing at second order in the hydrodynamic expansion for a non-interacting gas of chiral fermions by using the partition function formalism. We discuss some features of the ...
Soka kosmikoen ondorio behagarrien iragarpen eta froga berriak
(2016-02-29)
Soka kosmikoak unibertsoaren lehendabiziko garaietan gertatzen ziren prozesuen fisika ulertzeko oso erabilgarriak izan daitezke, hauek baitira kosmologiaren eredu estandarraren eta partikulen fisika duten energia altuko ...
Measurement of the Tau Michel Parameters (Eta)Over-Bar and Xi Kappa in the Radiative Leptonic Decay Tau(-) -> L(-)Nu(Tau)(Nu)Over-Bar(L)Gamma
(Oxford University Press, 2018-02)
We present a measurement of the Michel parameters of the tau lepton, (eta) over bar and xi kappa, in the radiative leptonic decay tau(-) -> l(-)nu(tau)(nu) over bar (l)gamma using 711 fb(-1) of collision data collected ...
