Galaxy Galaxy Lensing as a Probe of Galaxy Dark Matter Halos

, 2006
Gravitational lensing has now become a popular tool to measure the mass distribution of structures in the Universe on various scales. Here we focus on the study of galaxy's scale dark matter halos with galaxy-galaxy lensing techniques: observing the shapes of distant background galaxies which have been lensed by foreground galaxies allows us to map the

Constructing a Galaxy Cluster Catalog in IllustrisTNG300 Using the Mulguisin Algorithm

The Astrophysical Journal
We present a new simulated galaxy cluster catalog based on the IllustrisTNG simulation. We use the Mulguisin (MGS) algorithm to identify galaxy overdensities.

Origin and Full Characterization of the Secondary (Assembly) Halo Bias

The Astrophysical Journal
The clustering of dark matter halos depends not only on their mass, the so-called primary bias, but also on their internal properties, the so-called secondary bias.

SIDM Concerto: Compilation and Data Release of Self-interacting Dark Matter Zoom-in Simulations

The Astrophysical Journal
We present SIDM Concerto: 14 cosmological zoom-in simulations in cold dark matter (CDM) and self-interacting dark matter (SIDM) models based on the Symphony and Milky Way-est suites.
