Context. The formation of cosmic structures culminates with the assembly of galaxy clusters, a process that is quite different from cluster to cluster. Aims: We...
The Veritas and Themis asteroid families: 5-14 μm spectra with the Spitzer Space Telescope
Spectroscopic investigations of primitive asteroid families constrain family evolution and composition and conditions in the solar nebula, and reveal...
The Vertical Metallicity Gradient of the Milky Way Disk: Transitions in [α/Fe] Populations
Using G dwarfs from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey, we have determined the vertical metallicity gradient in the...
The vertical stellar distribution in NGC 6504: Detection of a thick disk
The vertical stellar distribution of the edge-on spiral NGC 6504 is examined in seven bands (U, B, R, I, J, H, K) by fitting model distributions to the light...
The vertical structure of the spiral galaxy NGC 3501: first stages of the formation of a thin metal-rich disc
We trace the evolution of the edge-on spiral galaxy NGC 3501, making use of its stellar populations extracted from deep integral-field spectroscopy MUSE...
The very faint hard state of the persistent neutron star X-ray binary SLX 1737-282 near the Galactic Centre
We report on a detailed study of the spectral and temporal properties of the neutron star low-mass X-ray binary SLX 1737-282, which is located only ∼1° away...
The Very Red Afterglow of GRB 000418: Further Evidence for Dust Extinction in a Gamma-Ray Burst Host Galaxy
We report near-infrared and optical follow-up observations of the afterglow of the GRB 000418 starting 2.5 days after the occurrence of the burst and extending...
The visible and near-infrared spectra of asteroids in cometary orbits
Context. Dynamical and albedo properties suggest that asteroids in cometary orbits (ACOs) are dormant or extinct comets. Their study provides new insights for...
