IBEX—Interstellar Boundary Explorer

Space Explorer

Explorer MOSAIC

Background: The recent availability of complete sequences for numerous closely related bacterial genomes opens up new challenges in comparative genomics. Several methods have been developed to align complete genomes at the nucleotide level but their use and the biological interpretation of results are not straightforward. It is therefore necessary to develop new resources to access, analyze, an...

Evolving outer heliosphere: Large‐scale stability and time variations observed by the Interstellar Boundary Explorer

[1] The first all‐sky maps of Energetic Neutral Atoms (ENAs) from the Interstellar Boundary Explorer (IBEX) exhibited smoothly varying, globally distributed flux and a narrow “ribbon” of enhanced ENA emissions. In this study we compare the second set of sky maps to the first in order to assess the possibility of temporal changes over the 6 months between views of each portion of the sky. While ...

Separation of the Interstellar Boundary Explorer Ribbon from Globally Distributed Energetic Neutral Atom Flux

The Interstellar Boundary Explorer (IBEX) observes a remarkable feature, the IBEX ribbon, which has energetic neutral atom (ENA) flux over a narrow region ∼20◦ wide, a factor of 2–3 higher than the more globally distributed ENA flux. Here, we separate ENA emissions in the ribbon from the distributed flux by applying a transparency mask over the ribbon and regions of high emissions, and then sol...

Introducing the Iranian moss flora explorer

Mosses (a section of bryophytes), are considered as an important group of non-flowering plants which a modern computer-assisted database system is not yet prepared for their determination and description key in Iran. Following a software package recently designed under a research project for assessment of moss diversity of Iran by the authors, the present paper is prepared to: I) introducing co...
