Molecular Spiral Structure in M51

1990
We 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.

Neutral Hydrogen near M51

1990
We observed the nearby Sc galaxy M51 (NGC 5194) and its companion NGC 5195 with the VLA in the 21-cm line to study the distribution and kinematics of the HI. M51 is a key object in the study of galaxies: its beautiful spiral structure with the clear separation of the dust lanes and associated radio continuum emission from the bright HII regions and OB ...

Dynamical Status of M51

1990
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 [

Possibile pianeta extragalattico in M51

2021
È grande 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 ...
