Mass distribution and accretion of sub-halos
Yun Li, Houjun Mo
We use the "Millennium Simulation" to study the mass function of accreted sub-halos during merger events in the dark halo assembly history. Our study includes three kinds of sub-ha…
Structural Properties of Central Galaxies in Groups and Clusters
Yicheng Guo, Daniel H. McIntosh, H. J. Mo +6
Using a representative sample of 911 central galaxies (CENs) from the SDSS DR4 group catalogue, we study how the structure of the most massive members in groups and clusters depend…
Modeling Galaxy-Galaxy Weak Lensing with SDSS Groups
Ran Li, H. J. Mo, Zuhui Fan +4
We use galaxy groups selected from the Sloan Digital Sky Survey (SDSS) together with mass models for individual groups to study the galaxy-galaxy lensing signals expected from gala…
Ongoing Assembly of Massive Galaxies by Major Merging in Large Groups and Clusters from the SDSS
Daniel H. McIntosh, Yicheng Guo, Jen Hertzberg +4
We investigate the incidence of major mergers creating >10e11 Msun galaxies in present-day groups and clusters more massive than 2.5e13 Msun. We identify 38 pairs of massive galaxi…
Galaxy Groups in the SDSS DR4: I. The Catalogue and Basic Properties
Xiaohu Yang, H. J. Mo, Frank C. van den Bosch +3
We use a modified version of the halo-based group finder developed by Yang et al. to select galaxy groups from the Sloan Digital Sky Survey (SDSS DR4). In the first step, a combina…
Nanoscale Observation of Alkane Delayering
M. Bai, K. Knorr, M. J. Simpson +6
Noncontact Atomic Force Microscopy and synchrotron x-ray scattering measurements on dotriacontane (n-C32H66 or C32) films adsorbed on SiO2-coated Si(100) wafers reveal a narrow tem…
