Is the supernova remnant RX J1713.7-3946 a hadronic cosmic-ray accelerator?
(IOP Publishing, 2001-12)
The nonthermal supernova remnant (SNR) RX J1713.7-3946 has recently been shown to be a site of cosmic-ray (CR) electron acceleration to TeV energies. Here we present evidence that this remnant is also accelerating CR nuclei. ...
The State-of-Play of anomalous microwave eission (AME) research
(Elsevier, 2018)
Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range approximate to 10-60 GHz. AME was first detected in 1996 and recognised as an additional component of ...
The evolution of the cosmic microwave background temperature Measurements of T(CMB) at high redshift from carbon monoxide excitation
(EDP SCIENCES S A,, 2011-02)
A milestone of modern cosmology was the prediction and serendipitous discovery of the cosmic microwave background (CMB), the radiation leftover after decoupling from matter in the early evolutionary stages of the Universe. ...
The evolution of the cosmic microwave background temperature. Measurements of TCMB at high redshift from carbon monoxide excitation
(2011)
A milestone of modern cosmology was the prediction and serendipitous discovery of the Cosmic Microwave Background (CMB), the radiation left over after decoupling from matter in the early evolutionary stages of the Universe. ...
Scalar particles in weak gravitational fields
(2004)
Scalar quantum particles are considered in Lense–Thirring spacetimes with a cosmic string passing through them, and of a slowly rotating global monopole. The solutions of the Klein–Gordon equation in these backgrounds are ...
Cordas cósmicas girantes na gravitação de Brans-Dicke
(Universidade Estadual Paulista (Unesp), 2018-02-23)
A partir da teoria da gravitação de Brans-Dicke, são obtidas soluções exatas para as cordas cósmicas girantes. As soluções são para cordas retas, que preservam a simetria de Lorentz ao longo do eixo longitudinal de simetria, ...
