Pressure support versus thermal broadening in the Lyman alpha forest - I. Effects of the equation of state on longitudinal structure
low-density intergalactic gas temperature
2014/12/22
In the low-density intergalactic medium that gives rise to the Lyman α (Lyα) forest, gas temperature and density are tightly correlated. The velocity scale of thermal broadening and the Hubble flow ac...
The study of neutron stars is a topic of central interest in the investigation of the properties of strongly compressed hadronic matter. Whereas in heavy-ion collisions the fireball, created in the co...
The Resolved Structure and Dynamics of an Isolated Dwarf Galaxy: A VLT and Keck Spectroscopic Survey of WLM
Resolved Structure Dynamics Isolated Dwarf Galaxy VLT Keck Spectroscopic Survey WLM
2012/2/23
We present spectroscopic data for 180 red giant branch stars in the isolated dwarf irregular galaxy WLM. Observations of the Calcium II triplet lines in spectra of RGB stars covering the entire galaxy...
The Information Of The Milky Way From 2MASS Whole Sky Star Count: The Structure Parameters
Milky Way Star Count:Structure Parameters
2011/10/12
The Ks band differential star count of the Two Micron All Sky Survey (2MASS) is used to derive the global structure parameters of the smooth components of the Milky Way. To avoid complication introduc...
Structure and Population of the NGC55 Stellar Halo from a Subaru/Suprime-Cam Survey
Population Stellar Halo Subaru Suprime-Cam Survey
2011/9/28
As part of our survey of galactic stellar halos, we investigate the structure and stellar populations of the northern outer part of the stellar halo in NGC55, a member galaxy of the Sculptor Group, us...
Galaxy Structure and Mode of Star Formation in the SFR-Mass Plane from z ~ 2.5 to z ~ 0.1
Galaxy Structure Star Formation SFR-Mass Plane
2011/9/27
We analyze the dependence of galaxy structure (size and Sersic index) and mode of star formation (\Sigma_SFR and SFR_IR/SFR_UV) on the position of galaxies in the SFR versus Mass diagram. Our sample c...
