We report the bivariate $HI$ - and $H 2$ -stellar mass distributions of local galaxies in addition of an inventory of galaxy mass functions, MFs, for $HI$ , $H 2$ , cold gas, and baryonic mass, separately into early- and late-type galaxies. The MFs are determined using the $HI$ and $H 2$ conditional distributions and the galaxy stellar mass

The determination of the observational limit below which the cores of very-low mass objects do not reach high enough temperatures and pressure for lithium destruction is called the lithium depletion boundary (LDB). Up to now, the LDB has been used to derive ages of several open clusters younger than 200 Myr, age considered as the practical upper

Sunspots are the most prominent feature of the solar magnetism in the photosphere. Although they have been widely investigated in the past, their structure remains poorly understood. Indeed, due to limitations in observations and the complexity of the magnetic field estimation at chromospheric heights, the magnetic field structure of sunspot above

Galaxy clusters are excellent targets for high energy astrophysics with gamma rays. Not only they may host active galaxies, but they are often expected to provide signatures of accelerations of electrons and protons to PeV energies. Furthermore, according to ΛCDM scenario, they should be embedded in an extremely massive dark matter halo, the

The Lithium content in stars is very sensitive to the internal stellar conditions. Indeed, Lithium is readily destroyed in the interiors of low-mass main-sequence (MS) stars and the Li in the convective envelope is progressively depleted. The Li abundance at the stellar surface was expected to be further depleted after stars leave the MS and

Early-type galaxies (ETGs) are of crucial importance to trace back the galaxy mass assembly across cosmic time, yet their formation and quenching remain remarkably elusive. The discoveries of massive, dead galaxies at ever-growing redshifts provided compelling evidence to push their formation up to redshift > 4-5 when the Universe was barely 1 Gyr
