The morphological dependent Tully-Fisher relation of spiral galaxies
Shiyin Shen, Caihong Wang, Ruixiang Chang +3
The Tully-Fisher relation of spiral galaxies shows notable dependence on morphological types, with earlier type spirals having systematically lower luminosity at fixed maximum rota…
Milky Way vs Andromeda: a tale of two disks
J. Yin, J. L. Hou, N. Prantzos +4
We study the chemical evolution of the disks of the Milky Way (MW) and of Andromeda (M31), in order to reveal common points and differences between the two major galaxies of the Lo…
The color gradients of spiral disks in the Sloan Digital Sky Survey
C. Z. Liu, S. Y. Shen, Z. Y. Shao +4
We investigate the radial color gradients of galactic disks using a sample of about 20,000 face-on spiral galaxies selected from the fourth data release of the Sloan Digital Sky Su…
Estimating the H I gas fractions of galaxies in the local Universe
Wei Zhang, Cheng Li, Guinevere Kauffmann +5
We use a sample of 800 galaxies with H I mass measurements from the HyperLeda catalogue and optical photometry from the fourth data release of the Sloan Digital Sky Survey to calib…
