The far-infrared disk of M51

open access: yesThe Astrophysical Journal, 1982
Far-infrared maps and multifrequency photometry are presented for M51 and its companion galaxy NGC 5195. Dust reradiates about half the starlight of the M51 + NGC 5195 system to produce the observed far-infrared (80-200 microns) luminosity of 3 x 10 to the 10th solar luminosities.

Detection of Deuterated Hydrocarbon Nanoparticles in the Whirlpool Galaxy, M51

open access: yesThe Astrophysical Journal Letters
Deuteration of hydrocarbon material, including polycyclic aromatic hydrocarbons (PAHs), has been proposed to account for the low gas-phase abundances of D in the interstellar medium (ISM). JWST spectra of four star-forming regions in M51 show an emission

Basic Tools for Studies on the Formation and Disruption of Star Clusters: the Luminosity Function

open access: yes, 2009
The luminosity function (LF) of young star clusters is often approximated by a power law function. For clusters in a wide range of galactic environments this has resulted in fit indices near -2, but on average slightly steeper.

CO Isotopologue-derived Molecular Gas Conditions and CO-to-H2 Conversion Factors in M51

open access: yesThe Astronomical Journal
Over the past decade, several millimeter interferometer programs have mapped the nearby star-forming galaxy M51 at a spatial resolution of ≤170 pc. This study combines observations from three major programs: the PdBI Arcsecond Whirlpool Survey, the SMA ...
