Monthly Notices of the Royal Astronomical Society, 475(1), https://doi.org/10.1093/mnras/stx3241

With the advent of wide-field cosmological surveys, we are approaching samples of hundreds of thousands of galaxy clusters. While such large numbers will help reduce statistical uncertainties, the control of systematics in cluster masses is crucial.... Read More about Galaxy Cluster Mass Reconstruction Project: III.

Astronomy and Astrophysics, 608, Article A123. https://doi.org/10.1051/0004-6361/201731476

The fraction of Lyman-α emitters (LAEs) among the galaxy population has been found to increase from z ~ 0 to z ~ 6 and drop dramatically at z> 6. This drop has been interpreted as an effect of an increasingly neutral intergalactic medium (IGM) with i...

Astrophysical Journal Letters, 851(2), Article L33. https://doi.org/10.3847/2041-8213/aa8ace

The “kinematic” morphology–density relation for early-type galaxies posits that those galaxies with low angular momentum are preferentially found in the highest-density regions of the universe. We use a large sample of galaxy groups with halo masses... Read More about SDSS-IV MaNGA: probing the kinematic morphology–density relation of early-type galaxies with MaNGA.

Magnetic monopole mass bounds from heavy ion collisions and neutron stars (2017)
Journal Article

Magnetic monopoles, if they exist, would be produced amply in strong magnetic fields and high temperatures via the thermal Schwinger process. Such circumstances arise in heavy-ion collisions and in neutron stars, both of which imply lower bounds on t...

Nano Letters, 18(1), 498-504. https://doi.org/10.1021/acs.nanolett.7b04453

Lattice-matched graphene on hexagonal boron nitride is expected to lead to the formation of a band-gap but requires the formation of highly strained material and has not hitherto been realised. We demonstrate that aligned, lattice-matched graphene ca... Read More about Lattice-Matched Epitaxial Graphene Grown on Boron Nitride.
