The" green valley" is a wide region separating the blue and the red peaks in the ultraviolet-
optical color magnitude diagram, first revealed using GALEX UV photometry. The term was …

Based on rigorous experimental, clinical, and mathematical analysis, the mechanism of
accommodation and presbyopia is elucidated. During accommodation the anterior radial …

We constrain the slope of the star formation rate (SFR; log Ψ) to stellar mass (log M⋆)
relation down to log (M⋆/M☉)= 8.4 (log (M⋆/M☉)= 9.2) at z= 0.5 (z= 2.5) with a mass …

We present the characterization of the main properties of a sample of 98 AGN host galaxies,
both type-II and type-I, in comparison with those of≈ 2700 non-active galaxies observed by …

We point out a natural mechanism for quenching of star formation in early-type galaxies
(ETGs). It automatically links the color of a galaxy with its morphology and does not require …

The environment is known to affect the formation and evolution of galaxies considerably best
visible through the well-known morphology–density relationship. It is less clear, though …

We use HST/WFC3 imaging from the CANDELS Multi-Cycle Treasury Survey, in conjunction
with the Sloan Digital Sky Survey, to explore the evolution of galactic structure for galaxies …

Making use of H i 21 cm line measurements from the ALFALFA survey (α. 40) and
photometry from the Sloan Digital Sky Survey (SDSS) and Galaxy Evolution Explorer …

We analyse the merger and assembly histories of Milky Way (MW) and Andromeda (M31)-
like galaxies to quantify how, and how often, disc galaxies of this mass can survive recent …

We make use of interferometric CO and H i observations, and optical integral-field
spectroscopy from the ATLAS3D survey, to probe the origin of the molecular and ionized …
