Scaling Relations between Gas and Star Formation in Nearby Galaxies
F. Bigiel, A. Leroy, F. Walter
High resolution, multi-wavelength maps of a sizeable set of nearby galaxies have made it possible to study how the surface densities of HI, H2 and star formation rate (Sigma_HI, Si…
Unusually Luminous Giant Molecular Clouds in the Outer Disk of M33
F. Bigiel, A. Bolatto, A. Leroy +5
We use high spatial resolution (~7pc) CARMA observations to derive detailed properties for 8 giant molecular clouds (GMCs) at a galactocentric radius corresponding to approximately…
SLUG: A new way to Stochastically Light Up Galaxies
Michele Fumagalli, Robert da Silva, Mark Krumholz +1
We present SLUG, a new code to "Stochastically Light Up Galaxies". SLUG populates star clusters by randomly drawing stars from an initial mass function (IMF) and then following the…
CARMA Survey Toward Infrared-bright Nearby Galaxies (STING): Molecular Gas Star Formation Law in NGC4254
Nurur Rahman, Alberto D. Bolatto, Tony Wong +11
This study explores the effects of different assumptions and systematics on the determination of the local, spatially resolved star formation law. Using four star formation rate (S…
Tightly Correlated HI and FUV Emission in the Outskirts of M83
F. Bigiel, A. Leroy, M. Seibert +4
We compare sensitive HI data from The HI Nearby Galaxy Survey (THINGS) and deep far UV (FUV) data from GALEX in the outer disk of M83. The FUV and HI maps show a stunning spatial c…
Extremely Inefficient Star Formation in the Outer Disks of Nearby Galaxies
F. Bigiel, A. Leroy, F. Walter +4
(Abridged) We combine data from The HI Nearby Galaxy Survey and the GALEX Nearby Galaxy Survey to study the relationship between atomic hydrogen (HI) and far-ultraviolet (FUV) emis…
