Projection effects in the strong lensing study of subhaloes
Ran Li, Carlos S. Frenk, Shaun Cole +2
The defining characteristic of the cold dark matter (CDM) hypothesis is the presence of a very large number of low-mass haloes, too small to have made a visible galaxy. Other hypot…
SDSS-IV MaNGA: environmental dependence of stellar age and metallicity gradients in nearby galaxies
Zheng Zheng, Huiyuan Wang, Junqiang Ge +20
We present a study on the stellar age and metallicity distributions for 1105 galaxies using the STARLIGHT software on MaNGA integral field spectra. We derive age and metallicity gr…
SDSS-IV MaNGA: Properties of galaxies with kinematically decoupled stellar and gaseous components
Yifei Jin, Yanmei Chen, Yong Shi +30
We study the properties of 66 galaxies with kinematically misaligned gas and stars from MaNGA survey. The fraction of kinematically misaligned galaxies varies with galaxy physical…
The growth of the central region by acquisition of counter-rotating gas in star-forming galaxies
Yan-Mei Chen, Yong Shi, Christy A. Tremonti +29
Galaxies grow through both internal and external processes. In about 10% of nearby red galaxies with little star formation, gas and stars are counter-rotating, demonstrating the im…
Galaxy-Galaxy Weak Lensing Measurements from SDSS: I. Image Processing and Lensing signals
Wentao Luo, Xiaohu Yang, Jun Zhang +11
As the first paper in a series on the study of the galaxy-galaxy lensing from Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we present our image processing pipeline that corr…
