  1. 15. Gas distribution and Star formation activities in the Galactic Plane
    Nalin Vutisalchavakul (University of Texas at Austin)

    Poster
    Combining several large scale Galactic plane surveys, we studied the gas distribution and star formation activities in part of the Galactic plane. Star formation rates were determined from infrared data obtained from WISE and Spitzer surveys. The Bolocam Galactic Plane Survey provided the data of 1.1mm dust continuum and dense gas tracers, while the Galactic Ring Survey provided the data of...

  2. 14. Radio-FIR correlation as a probe to interplay between star formation as ISM
    23/10/2013, 09:00
    Poster
    We investigate the correlation between the radio continuum and far-infrared (FIR) emission in the Fireworks galaxy NGC6946. The nonthermal radio-FIR correlation changes with both star formation and magnetic field strengths. The FIR-to-radio ratio is linearly correlated with the total magnetic field strength. This connection is self-consistent and independent from the star formation feedback....

  3. 152. Simulating an Accreting, Star Forming Galactic Disc

    In galaxies stars are formed from a reservoir of cold molecular gas. For star formation to continue this reservoir has to be fueled with extragalactic material or else the gas is depleted. In this project we use the SPH-code GADGET to simulate a spiral galaxy that is constantly fed with new gas at a rate of five solar masses per year. We find that the star formation rate tries to adjust to the...

  4. 46. Turbulence in Molecular Clouds: Measuring the density distribution
    Adam Ginsburg (University of Colorado, Boulder / European Southern Observatory)

    Poster
    Turbulence is one of the primary processes governing star formation. Many recent theories have determined the overall star formation rate of gas and even the shape of the initial mass function based purely on turbulent initial conditions. The key property governing star formation rates is the density distribution of the gas, which determines how much gas is above some "critical density" for...
