Constraints on the identity of the dark matter from strong gravitational lenses
Ran Li, Carlos S. Frenk, Shaun Cole +3
The cold dark matter (CDM) cosmological model unambigously predicts that a large number of haloes should survive as subhaloes when they are accreted into a larger halo. The CDM mod…
Assessing the Jeans Anisotropic Multi-Gaussian Expansion method with the Illustris simulation
Hongyu Li, Ran Li, Shude Mao +3
We assess the effectiveness of the Jeans-Anisotropic-MGE (JAM) technique with a state-of-the-art cosmological hydrodynamic simulation, the Illustris project. We perform JAM modelli…
Measuring subhalo mass in redMaPPer clusters with CFHT Stripe 82 Survey
Ran Li, Huanyuan Shan, Jean-Paul Kneib +10
We use the shear catalog from the CFHT Stripe-82 Survey to measure the subhalo masses of satellite galaxies in redMaPPer clusters. Assuming a Chabrier Initial Mass Function (IMF) a…
The Mass-Concentration Relation and the Stellar-to-Halo Mass Ratio in the CFHT Stripe 82 Survey
Huanyuan Shan, Jean-Paul Kneib, Ran Li +8
We present a new measurement of the mass-concentration relation and the stellar-to-halo mass ratio over the halo mass range to . To achi…
