Aims: The importance of disc-disc major mergers in galaxy evolution remains uncertain. We study the major merger fraction in a SPITZER/IRAC-selected catalogue...
The galaxy size to halo spin relation of disc galaxies in cosmological hydrodynamical simulations
In the standard disc galaxy formation model, the sizes of galactic discs are tightly related to the spin parameters λ of their dark matter haloes. The model has...
The Galaxy-wide Distributions of Mean Electron Density in the H II Regions of M51 and NGC 4449
Using Advanced Camera for Surveys-Hubble Space Telescope images to yield continuum-subtracted photometric maps in Hα of the Sbc galaxy M51 and the dwarf...
The galaxy-wide initial mass function of dwarf late-type to massive early-type galaxies
Observational studies are showing that the galaxy-wide stellar initial mass function (IMF) is top-heavy in galaxies with high star formation rates (SFRs)...
The GALEX/S4G Surface Brightness and Color Profiles Catalog. I. Surface Photometry and Color Gradients of Galaxies
We present new spatially resolved surface photometry in the far-ultraviolet (FUV) and near-ultraviolet (NUV) from images obtained by the Galaxy Evolution...
The GALEX/S4G UV–IR Color–Color Diagram: Catching Spiral Galaxies Away from the Blue Sequence
We obtained GALEX FUV, NUV, and Spitzer/IRAC 3.6 μm photometry for \gt 2000 galaxies, available for 90% of the S4G sample. We find a very tight GALEX blue...
The Gamma-Ray Bright BL Lacertae Object RX J1211+2242
RX J1211+2242 is an optically faint (B~=19.2mag) but X-ray bright (f2-10keV=5×10-12ergscm-2s-1) active galactic nucleus (AGN) that has been shown to be a BL Lac...
The GAPS Programme at TNG XXXIX. Multiple Molecular Species in the Atmosphere of the Warm Giant Planet WASP-80 b Unveiled at High Resolution with GIANO-B
Detections of molecules in the atmosphere of gas giant exoplanets allow us to investigate the physico-chemical properties of the atmospheres. Their inferred...
The GAPS programme at TNG. L. TOI-4515 b: An eccentric warm Jupiter orbiting a 1.2 Gyr-old G-star
Context. Different theories have been developed to explain the origins and properties of close-in giant planets, but none of them alone can explain all of the...
