Regulation of Bone Metabolism
Bone is formed through the processes of endochondral and intramembranous ossification. In endochondral ossification primary mesenchymal cells differentiate to chondrocytes and then are progressively substituted by bone, while in intramembranous ossification mesenchymal stem cells (MSCs) differentiate directly into osteoblasts to form bone. The steps of osteogenic proliferation, differentiation,...
متن کاملGalaxy-galaxy-galaxy lensing: Third-order correlations between the galaxy and mass distributions in the Universe
Abstract. Galaxy-galaxy lensing (GGL) measures the 2-point cross-correlation between galaxies and mass in the Universe. In this work we seek to generalise this effect by considering the third-order correlations between galaxies and mass: galaxy-galaxy-galaxy lensing. Third-order correlations in the cosmic shear field have recently been reported in the VIRMOS-DESCART and CTIO surveys. Such data ...
متن کاملStudying Galaxy Formation in Loose Galaxy Groups
We present the results of our HI survey of six loose groups of galaxies analogous to the Local Group. The survey was conducted using the Parkes telescope and the Australia Telescope Compact Array to produce a census of all the gas-rich galaxies and analogs to the high-velocity clouds (HVCs) within these groups down to MHI< 10 M⊙ as a test of models of galaxy formation. We present the HI mass fu...
متن کاملQuantitative analysis of galaxy-galaxy lensing
Gravitational light deflection due to mass along the line-of-sight will distort the images of background sources. This effect has been used successfully to investigate the mass distribution of galaxy clusters. Although an individual galaxy is not massive enough to cause a detectable lensing distortion in the background population, this effect can be measured statistically for a population of ga...
متن کاملGalaxy Activity in Merging Binary Galaxy Clusters
We present the results of a study of galaxy activity in two merging binary clusters (A168 and A1750) using the Sloan Digital Sky Survey (SDSS) data supplemented with the data in the literature. We have investigated the merger histories of A168 and A1750 by combining the results from a two-body dynamical model and X-ray data. In A168 two subclusters appear to have passed each other and to be com...
