NRO M33 All-Disk Survey of Giant Molecular Clouds (NRO MAGiC): II. Dense Gas Formation within Giant Molecular Clouds in M33
We have conducted observations of the 12CO(J=1–0) and 12CO(J = 3–2) line emission of 74 major giant molecular clouds (GMCs) within the galactocentric distance of 5.1 kpc in the Local Group galaxy M33 [1]. The observations are part of the Nobeyama Radio Observatory M33 All-disk survey of Giant Molecular Clouds project (NRO MAGiC [2]). The spatial resolution is 100 pc. We detect 12CO(J = 3–2) emi...
متن کاملGiant Molecular Clouds in M 33 I – Bima All - Disk Survey
We present the first interferometric 12 CO (J = 1 → 0) map of the entire Hα disk of M33. The 13 ′′ diameter synthesized beam corresponds to a linear resolution of 50 pc, sufficient to distinguish individual giant molecular clouds (GMCs). From these data we generated a catalog of 148 GMCs with an expectation that no more than 15 of the sources are spurious. The catalog is complete down to GMC ma...
متن کاملGiant Molecular Clouds in M 64
We investigate the properties of Giant Molecular Clouds (GMCs) in the molecule-rich galaxy M64 (NGC 4826). In M64, the mean surface density of molecular gas is 2N (H 2) ∼ 10 22 over a 2 kpc region, equal to the surface densities of individual GMCs in the Milky Way. We observed the J = 1 → 0 transitions of CO, 13 CO, and HCN. The line ratio W CO /W 13CO for 200 pc < R gal < 800 pc is comparable ...
متن کاملStar formation in M 33 : multiwavelength signatures across the disk
Aims. We use different tracers, such as Hα, ultraviolet (UV), and infrared (IR) emissions at various wavelengths, to study the dust and star-formation (SF) conditions throughout the disk of M 33. Methods. We derive the radial distribution of dust, of the old and young stellar population using Spitzer and GALEX data, complemented by ground-based optical data and available surveys of atomic and m...
متن کاملThe volume densities of giant molecular clouds in M 83
Using observed GALEX far-ultraviolet (FUV) fluxes and VLA images of the 21-cm HI column densities, along with estimates of the local dust abundances, we measure the volume densities of a sample of actively star-forming giant molecular clouds (GMCs) in the nearby spiral galaxy M83 on a typical resolution scale of 170 pc. Our approach is based on an equilibrium model for the cycle of molecular hy...
