Cosmic particle colliders: simulations of self-interacting dark matter with anisotropic scattering
Andrew Robertson, Richard Massey, Vincent Eke
We investigate how self-interacting dark matter (SIDM) with anisotropic scattering affects the evolution of isolated dark matter haloes as well as systems with two colliding haloes…
How thick are Mercury's polar water ice deposits?
Vincent R. Eke, David J. Lawrence, Luıs F. A. Teodoro
An estimate is made of the thickness of the radar-bright deposits in craters near to the north pole of Mercury. To construct an objective set of craters for this measurement, an au…
What does the Bullet Cluster tell us about self-interacting dark matter?
Andrew Robertson, Richard Massey, Vincent Eke
We perform numerical simulations of the merging galaxy cluster 1E 0657-56 (the Bullet Cluster), including the effects of elastic dark matter scattering. In a similar manner to the…
Knowing the unknowns: uncertainties in simple estimators of galactic dynamical masses
David J. R. Campbell, Carlos S. Frenk, Adrian Jenkins +7
The observed stellar kinematics of dispersion-supported galaxies are often used to measure dynamical masses. Recently, several analytical relationships between the stellar line-of-…
