The Spatially Resolved Star Formation Law From Integral Field Spectroscopy: Virus-P Observations Of NGC 5194

Blanc, Guillermo A.; Heiderman, Amanda; Gebhardt, Karl; Evans, Neal J.; Adams, Joshua (2009-10)

We investigate the relation between the star formation rate (SFR) surface density (Sigma(SFR)) and the mass surface density of gas (Sigma(gas)) in NGC 5194 (a.k.a. M51a, Whirlpool Galaxy). Visible Integral field Replicable ...

The Virus-P Exploration Of Nearby Galaxies (Venga): The X-Co Gradient In NGC 628
