    Galactic evolution of nitrogen
    We present detailed spectroscopic analysis of nitrogen abundances in 31 unevolved metal-poor stars analysed by spectral synthesis of the near-UV NH band at 3360...

    Galactic rings and secular evolution in barred galaxies
    Rings are common in galaxies. Several kinds of rings are known: collisional, polar, and resonance rings, of which the latter is by far most common. Resonance...

    Galactic warp in the overdensity of the Canis Major region
    Bellazzini et al. claim that López-Corredoira et al. warp model is totally unable to reproduce the Canis Major structure in the red clump stars. However, slight...

    Galactic-Field Initial Mass Functions of Massive Stars
    Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) appears to be an invariant...

    Galaxies at z>7: Probing galaxy formation with the new generation of NIR Instruments
    We present the results obtained from our deep survey of lensing clusters aimed at constraining the abundance of star-forming galaxies at z ˜ 6-11. Lensing...

    Galaxies like Russian dolls
    Jairo Méndez Abreu and Adriana de Lorenzo-Cáceres, researchers at the Instituto de Astrofísica de Canarias (IAC), have discovered a peanut-shaped structure in...

    Galaxies that feed on other galaxies
    An international team of astronomers led by Giuseppina Battaglia, researcher at the Instituto de Astrofísica de Canarias (IAC), finds signs that the outer halo...

    Galaxies with monstrous black holes in galaxy cluster environments
    Massive early-type galaxies follow a tight relation between the mass of their central supermassive black hole (MBH) and their stellar mass (M⋆). The origin of...

    Galaxies within galaxies in the TIMER survey: stellar populations of inner bars are scaled replicas of main bars
    Inner bars are frequent structures in the local Universe and thought to substantially influence the nuclear regions of disc galaxies. In this study we explore...
