We study the effect of a fluctuating active galactic nucleus (AGN) on the abundance of circumgalactic OVI in galaxies selected from the Evolution and Assembly of GaLaxies and their Environments simulations. We follow the time-variable OVI abundance i... Read More about Metals in the circumgalactic medium are out of ionization equilibrium due to fluctuating active galactic nuclei.

The lymphatic system of a vertebrate is important in health and diseases. We propose a novel mathematical model to elucidate the lymphangiogenic processes in zebrafish embryos. Specifically, we are interested in the period when lymphatic endothelial... Read More about A Mathematical Model of Lymphangiogenesis in a Zebrafish Embryo.

There exist conflicting observations on whether or not the environment of broad and narrow line AGN differ and this consequently questions the validity of the AGN unification model. The high spectroscopic completeness of the GAMA survey makes it idea... Read More about Galaxy and Mass Assembly (GAMA): active galactic nuclei in pairs of galaxies.
