Giuseppe Donatiello (b. 14 December 1967)

it.wikipedia.org/wiki/Giuseppe_Donatiello

is an Italian amateur astronomer, astrophotographer and author. Known primarily as discoverer of 11 nearby dwarf galaxies, some planetary nebulae and author [ https://cosmo2050.com/author/giuseppe-donatiello/ ] of hundreds of articles in leading astronomical magazines on topics related to astronomical instrumentation, advanced image processing techniques, astronomical news and history of astronomy.

Specifically:
- Discoverer of a spheroidal dwarf galaxy 9.87 million light-years away, designated - absolute first time with the name of a non-professional - Donatiello I [ en.wikipedia.org/wiki/Donatiello_I ].

- Discoverer of Pisces VII/Triangulum III, an ultra faint dwarf galaxy (UFD) in the Local Group at 820 kpc (2.6 million light years) and belongs to the family of the Andromeda Galaxy (M31), possible new satellite of Messier 33 galaxy. The new galaxy is presented in a study led by Dr. David Martínez Delgado: https://doi.org/10.1093/mnras/stab2797

- Discoverer of three small satellite galaxies of NGC 253, designated Donatiello II, III and IV. The new galaxis are presented in a study led by Dr. David Martínez Delgado: https://doi.org/10.1051/0004-6361/202141242

- Discovery of an ultra-faint dwarf galaxy at about 2,2 milion light-years, satellite of M31, namd Pegasus V / Andromeda XXXIV. Pegasus V contains very few heavier elements, which means its stars are very old, hence its classification as a fossil of the first galaxies.
MNRAS Letters https://arxiv.org/abs/2204.09068

2024 - Five faint dwarf galaxies found in the DESI Legacy Survey, satellite candidates of NGC 253: Donatiello (Do) V, VI, VII, VIII and IX.
This new study was also led by David Martinez Delgado and is already available on the ArXiv platform: arxiv.org/pdf/2405.03769

- Discoverer of 4 planetary nebulae candidates and a problematic object, named respectively Donatiello Source (DoS) 1, 2, 3 and 4 and DoS Object 1 [DoS 1/PN-G 238.8+00.9, DoS 2/PN-G 241.0+03.1, DoS 3/PN-G 285.1-06.8, DoS 4/PN-G 045.0-21.9].[planetarynebulae.net/FR/page_np_resultat.php?id=860] .

Here is the list of all published or upcoming peer-reviewed articles:

He has participated in comet observation campaigns, including International Halley Watch and UCW, and still participates in Pro-Am collaborations in the field of galactic archeology, in particular in the study of dwarf galaxies, ultra-diffuse galaxies and stellar tidal streams.
He has proposed names for minor bodies of the Solar System and geological structures of other planets. Among his accepted proposals, the name of Anna Magnani assigned to a crater of 27 Km on Venus (1995) and the asteroid 77971 Donnolo.

IAU Dark Sky Ambassador [darkskies4all.org/users/profile/giuseppe-donatiello-702785/].
As an astrophotographer, he uses his own equipment but also data from professional Observatories, accessible in public Archives or in service mode. Some of these works are available here and they can be used freely with the C0 license, provided appropriate credits and/or thanks as reported in the images. All these images are made public, even if not always specified, as long as the author is mentioned in the credits.
