Journal Article
Lin, F. X., Lin, H. H., Luo, J., Main, R., McKee, J., Pen, U. L., …van Kerkwijk, M. H. (2021). Profile changes associated with dispersion measure events in PSR J1713+0747. Monthly notices of the Royal Astronomical Society, 508(1), 1115-1127. https://doi.org/10.1093/mnras/stab2529

Propagation effects in the interstellar medium and intrinsic profile changes can cause variability in the timing of pulsars, which limits the accuracy of fundamental science done via pulsar timing. One of the best timing pulsars, PSR J1713+0747, has... Read More about Profile changes associated with dispersion measure events in PSR J1713+0747.

Immune responses rely on a complex adaptive system in which the body and infections interact at multiple scales and in different compartments. We developed a modular model of CD4+ T cells, which uses four modeling approaches to integrate processes at...

Unravelling the physics of multiphase AGN winds through emission line tracers (2021)
Journal Article

Observations of emission lines in active galactic nuclei (AGNs) often find fast (∼1000 km s−1) outflows extending to kiloparsec scales, seen in ionized, neutral atomic and molecular gas. In this work we present radiative transfer calculations of emis... Read More about Unravelling the physics of multiphase AGN winds through emission line tracers.
