Journal ArticleDOI
The Star Formation Law in Nearby Galaxies on Sub-Kpc Scales
Frank Bigiel,Adam Leroy,Fabian Walter,Elias Brinks,W. J. G. de Blok,Barry F. Madore,Michele D. Thornley +6 more
TL;DR: In this article, the authors present a comprehensive analysis of the relationship between star formation rate surface density and gas surface density at sub-kpc resolution in a sample of 18 nearby galaxies and investigate how the star formation law differs between the H2 dominated centers of spiral galaxies, their H I dominated outskirts and the H I rich late-type/dwarf galaxies.
Journal ArticleDOI
Star Formation Thresholds in Galactic Disks
TL;DR: In this article, a detailed study of the star formation law in a sample of 32 nearby spiral galaxies with well-measured rotation curves, H I and H_2 (as traced by CO) surface density profiles, and new Hα CCD photometry was performed.
Journal ArticleDOI
The extended rotation curve and the dark matter halo of M33
Edvige Corbelli,Paolo Salucci +1 more
TL;DR: In this paper, the authors present the 21-cm rotation curve of the nearby galaxy M33 out to a galactocentric distance of 16 kpc (13 disk scale-lengths).

Interstellar Abundance Gradients in NGC 2403: Comparison to M33
Donald R. Garnett,Donald R. Garnett,Gregory A. Shields,Evan D. Skillman,Evan D. Skillman,S. P. Sagan,Reginald J. Dufour +6 more
TL;DR: In this article, a long-slit spectra of 12 H II regions in the Scd spiral galaxy NGC 2403 was presented, and the abundance gradients for O, N, S, Ne, and Ar were estimated using direct measurements of electron temperature based on detections of [O III] λ4363, [S III]- λ6312, and [O II] −7320-7330, and from theoretical photoionization analysis.

Giant Molecular Clouds in M33. II. High-Resolution Observations
TL;DR: In this article, the authors present 12CO (J = 1 → 0) observations of 45 giant molecular clouds (GMCs) in M33 made with the BIMA array.
