Decay of the vacuum energy into CMB photons
Reuven Opher, Ana Pelinson
We examine the possibility of the decay of the vacuum energy into cosmic microwave background (CMB) photons. It is shown that observations of the primordial density fluctuation spe…
A New Method for Studying the Topology of the Universe from the Cosmic Microwave Background
Reuven Opher
The standard method for observationally confirming the existence of a predicted finite topology of the universe involves searching for the repetition of the same finite or extended…
Summary Talk of the X Latin American Workshop on Plasma Physics
Reuven Opher
Of the many important topics that were discussed at the workshop, I summarize and comment on 25 presentations, which I found to be particularly interesting. They fall into all of t…
Studying the decay of the vacuum energy with the observed density fluctuation spectrum
Reuven Opher, Ana Pelinson
One of the major problems in cosmology today is to explain the observed acceleration of the universe. The present observational data are consistent with the simplest solution to th…
Problems with studying topology of the universe via circles from cosmic microwave background data
Evelise Gausmann, Reuven Opher
This paper has been withdrawn by the authors for future revision.
Origin of coherent magnetic fields in high redshift objects
A. Kandus, R. Opher, S. R. M. Barros
Large scale strong magnetic fields in galaxies are generally thought to have been generated by a mean field dynamo. In order to have generated the fields observed, the dynamo would…
