    The galaxy bias profile of cosmic voids
    Context. Cosmic voids are underdense regions within the large-scale structure of the Universe, spanning a wide range of physical scales ─ from a few megaparsecs...

    The galaxy counterpart and environment of the dusty damped Lyman-α absorber at z = 2.226 towards Q 1218+0832
    We report on further observations of the field of the quasar Q 1218+0832. Geier et al. (2019, A&A, 625, L9) presented the discovery of the quasar resulting from...

    The galaxy major merger fraction to {z} 1
    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 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...

    The GAPS Programme at TNG. LI. Investigating the correlations between transiting system parameters and host chromospheric activity
    Context. Stellar activity is the most relevant types of astrophysical noise that affect the discovery and characterization of extrasolar planets. On the other...

    The GAPS programme at TNG. LII. Spot modelling of V1298 Tau using the SpotCCF tool
    Context. The intrinsic variability due to the magnetic activity of young active stars is one of the main challenges in detecting and characterising exoplanets...

    The GAPS Programme at TNG. LIV. A He I survey of close-in giant planets hosted by M-K dwarf stars with GIANO-B
    Context. Atmospheric escape plays a fundamental role in shaping the properties of exoplanets. The metastable near-infrared (nIR) helium triplet at 1083.3 nm (He...

    The GAPS Programme at TNG. LV. Multiple molecular species in the atmosphere of HAT-P-11 b and review of the HAT-P-11 planetary system
    Context. The atmospheric characterisation of hot and warm Neptune-size exoplanets is challenging mainly due to their relatively small radius and atmospheric...

    The GAPS programme at TNG. XLIII. A massive brown dwarf orbiting the active M dwarf TOI-5375
    Context. Massive substellar companions orbiting active low-mass stars are rare. They, however, offer an excellent opportunity to study the main mechanisms...
