Characterization of the host galaxy from gamma-ray blazars
The most extreme electromagnetic radiation that can be observed is known as very high energy gamma rays (VHE, E>100 GeV). It is the last window open to the...
Chromospheric polarization in the photospheric solar oxygen infrared triplet.
We present multilevel radiative transfer modeling of the scattering polarization observed in the solar O I infrared triplet around 777 nm. We demonstrate that...
Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal): II. Unveiling the formation and evolution of the kinematically selected Thick and Thin Discs
Research on the formation, origin, and evolution of the dichotomy between the thin and thick disk components of the Milky Way has been a major topic of study...
Circumstellar effects on the Rubidium abundances in massive AGB stars.
Intermediate mass stars, in their last phases of evolution ("AGB stars"),produce a large number of heavy elements (rich in neutrons), some ofthem radioactive...
Collision of C-type Ryugu’s parent body with a rocky object
Hayabusa2’s optical navigation camera (ONC) found many anomalously bright boulders on the dark surface of the carbonaceous (or C-type) asteroid Ryugu...
The main objective of the NASA OSIRIS-REx mission is the collection of material from the surface of primitive asteroid (101955) Bennu, and to bring it back to...
Tests have been carried out for the first time on the hypothesis that the structure of interstellar dust around galactic bars is determined by the velocity...
The interstellar medium is an excellent laboratory to test physical processes that cannot be reproduced in Earth-based laboratories. In this study several...
Confronting fuzzy dark matter with the rotation curves of nearby dwarf irregular galaxies
Dark matter is an invisible substance that makes up more than eighty percent of the matter content of the universe. We know of its existence due to its...
