Discoverer of eleven nearby dwarf galaxies in the Local Volume | |
Contributions
edit- He discovered in 2016 a dwarf galaxy about 10 million light years away in the constellation of Andromeda called Donatiello I.[3] This is the first galaxy to be named after its non-professional discoverer.[4][5]
- In 2020, he discovered the ultrafaint dwarf galaxy named Pisces VII/Triangulum III[6][7] which turned out to be a strong satellite candidate of the dwarf spiral galaxy Messier 33.[8][9] Pisces VII is the first Local Group galaxy to be discovered by a non-professional astronomer.[10][11]

- Also in 2021, the discovery of three new satellites of the spiral galaxy NGC 253 was announced.[12] These three new dwarf galaxies were named Donatiello II, III and IV.[13] All were later observed and confirmed as satellites of NGC 253 by the Hubble Space Telescope.[14][15][16][17]
- In 2022, he discovered a very faint dwarf satellite galaxy of M31 which was named Pegasus V/Andromeda XXXIV.[18] This object turned out to be particularly ancient and could be a fossil of the first star formation.[19][20]
- In 2024, the discovery of five more satellite galaxies of the NGC 253 galaxy was announced. The new objects were named Donatiello V, VI, VII, VIII and IX[21][22]
To these discoveries must be added some candidate planetary nebulae[23] and the participation in the discovery and analysis of several dozen stellar streams[24][25]
He is the principal investigator and coordinator of the National Deep Sky Research Section of the Italian Amateur Astronomers Union[26]
