We study, within the Nambu-Goto approximation, the stability of massive string junctions under the influence of the tensions of three strings joining together in a Y-type configuration. The relative angle β between the strings at the junction is in g... Read More about Zipping and unzipping in string networks: dynamics of Y-junctions.

Is the universe transparent? (2015)
Journal Article
Liao, K., Avgoustidis, A., & Li, Z. (2015). Is the universe transparent?. Physical Review D, 92(12), Article 123539. https://doi.org/10.1103/PhysRevD.92.123539

We present our study on cosmic opacity, which relates to changes in photon number as photons travel from the source to the observer. Cosmic opacity may be caused by absorption or scattering due to matter in the Universe, or by extragalactic magnetic... Read More about Is the universe transparent?.
