Intracluster Light as a Probe for Dark Matter: Exploring Self-interacting Dark Matter and Cold Dark Matter with C-EAGLE Sims

Jaewon Yoo, Ellen L. Sirks, Cristiano G. Sabiu +5

We assess whether intracluster light (ICL) can serve as an observational discriminator of dark matter physics. The self-interacting dark matter (SIDM) model has gained increasing a…

Lensing in the Blue III: Weak Lensing Shape Catalogs of 30 Merging Galaxy Clusters

Sayan Saha, Jacqueline E. McCleary, Spencer W. Everett +38

We present the weak gravitational lensing dataset from the Super-pressure Balloon-Borne Imaging Telescope (SuperBIT), which imaged 30 galaxy clusters during its 45 night flight in…

Populating Large N-body Simulations with LRGs Using Neural Networks

M. Icaza-Lizaola, E. L. Sirks, Yong-Seon Song +2

The analysis of state-of-the-art cosmological surveys like the Dark Energy Spectroscopic Instrument (DESI) survey requires high-resolution, large-volume simulations. However, the c…

Hydrodynamical simulations of merging galaxy clusters: giant dark matter particle colliders, powered by gravity

Ellen L. Sirks, David Harvey, Richard Massey +7

Terrestrial particle accelerators collide charged particles, then watch the trajectory of outgoing debris - but they cannot manipulate dark matter. Fortunately, dark matter is the…

Strong gravitational lensing's 'external shear' is not shear

Amy Etherington, James W. Nightingale, Richard Massey +19

The distribution of mass in galaxy-scale strong gravitational lenses is often modelled as an elliptical power law plus 'external shear', which notionally accounts for neighbouring…

The effects of self-interacting dark matter on the stripping of galaxies that fall into clusters

Ellen L. Sirks, Kyle A. Oman, Andrew Robertson +2

We use the Cluster-EAGLE (C-EAGLE) hydrodynamical simulations to investigate the effects of self-interacting dark matter (SIDM) on galaxies as they fall into clusters. We find that…
