An Investigation of Disk Thickness in M51 from Hα, Paα, and Mid-infrared Power Spectra
Astrophysical JournalPower spectra (PS) of high-resolution images of M51 (NGC 5194) taken with the Hubble Space Telescope and the James Webb Space Telescope (JWST) have been examined for evidence of disk thickness in the form of a change in slope between large scales, which ...

The young stellar clusters in M51 and the impact of GMC encounters
Monthly notices of the Royal Astronomical SocietyWe investigate the young stellar cluster population of M51 and how it is affected by encounters with giant molecular clouds (GMCs). We combine a galactic model with N-body simulations of 5000 unique clusters in the mass range [600 − 24000] M⊙.

On the Nature of Spiral Arms in the Interacting Galaxy M51
Astronomy reports (Print)In this study, we investigated the radial variation of the azimuthal propagation of star formation across the spiral arms in the nearby galaxy NGC 5194 (M51a) by analysing the spatial separation between young star clusters and their nearest H II regions.

Possibile pianeta extragalattico in M51
2021grande come Saturno. Orbita ogni 70 anni attorno a una binaria X a 28 milioni di anni luce da noi, nella Galassia Vortice. Gli indizi della sua esistenza arrivano dalle misure compiute con i telescopi spaziali Chandra e Xmm-Newton per raggi X, e se confermato sarebbe il primo pianeta mai scoperto al di fuori della nostra ...

The controversy surrounding the delineation of molecular spiral structure in the Galaxy emphasizes that spiral structure can best be understood by observing external galaxies with high angular resolution. M51, the galaxy in which spiral structure was first discerned, is the obvious galaxy to observe. Lo et al.

M51 enjoys a special place in the history of observational astronomy. It was the first galaxy observed to have spiral structure, by Lord Rosse in 1845 using the 72-inch reflector at Burr Castle. Over a century later, M51 became the first galaxy outside the Local Group to be mapped extensively at radio wavelengths by Mathewson, van der Kruit, and Brouw [

Molecular Spiral Structure in M51
1990We present a mosaic map of M51 in the 12CO 1→0 line made with the Owens Valley mm-interferometer. The molecular arms we see are narrow and show an offset relative to the Ha emission. They also show coincidence with the dust lanes. Several interarm emission regions have also been detected, but with very little accompanying Ha emission.
