Phase-space structure in the local dark matter distribution and its signature in direct detection experiments
Mark Vogelsberger, Amina Helmi, Volker Springel +6
We study predictions for dark matter phase-space structure near the Sun based on high-resolution simulations of six galaxy halos taken from the Aquarius Project. The local DM densi…
The environments of starburst and post-starburst galaxies at z=0.4-0.8
Bianca M. Poggianti, Alfonso Aragon-Salamanca, Dennis Zaritsky +16
Post-starburst (E+A or k+a) spectra, characterized by their exceptionally strong Balmer lines in absorption and the lack of emission lines, belong to galaxies in which the star for…
Alignment between galaxies and large-scale structure
A. Faltenbacher, Cheng Li, Simon D. M. White +3
Based on the Sloan Digital Sky Survey DR6 (SDSS) and Millennium Simulation (MS) we investigate the alignment between galaxies and large-scale structure. For this purpose we develop…
Dark Matter Caustics
Simon D. M. White, Mark Vogelsberger
Caustics are a generic feature of the nonlinear growth of structure in the dark matter distribution. If the dark matter were absolutely cold, its mass density would diverge at caus…
Halo masses for optically-selected and for radio-loud AGN from clustering and galaxy-galaxy lensing
Rachel Mandelbaum, Cheng Li, Guinevere Kauffmann +1
We compute two-point correlation functions and measure the shear signal due to galaxy-galaxy lensing for 80,000 optically identified and 5,700 radio-loud AGN from Data Release 4 (D…
The relation between star formation, morphology and local density in high redshift clusters and groups
Bianca M. Poggianti, Vandana Desai, Rose Finn +17
We investigate how the [OII] properties and the morphologies of galaxies in clusters and groups at z=0.4-0.8 depend on projected local galaxy density, and compare with the field at…
