    The complex narrow line region in NGC 4151
    New narrow band images of NGC 4151, taken in excellent seeing conditions with the 4.2-m William Herschel Telescope on La Palma are presented. These reveal a...

    The Cosmic History of Black Hole Growth
    It is now clear that supermassive black holes (M>1e6 Msun) live in the center of most (all) galaxies, including our own Milky Way. Furthermore, the energy...

    The Evolving Interstellar Medium of Star-forming Galaxies, as Traced by Stardust
    We analyze the far-infrared (FIR) properties of ~5000 star-forming galaxies at z < 4.5, drawn from the deepest, super-deblended catalogs in the GOODS-N and...

    The First Identification of Lyα Changing-look Quasars at High Redshift in DESI
    We present two cases of Lyα changing-look (CL) quasars (J1306 and J1512) along with two additional candidates (J1511 and J1602), all discovered serendipitously...

    The GADOT Galaxy Survey: Dense Gas and Feedback in Herschel-selected Starburst Galaxies at Redshifts 2 to 6
    We report the detection of 23 OH + 1 → 0 absorption, emission, or P-Cygni-shaped lines and CO(J = 9→8) emission lines in 18 Herschel-selected z = 2-6 starburst...

    The Galaxy Activity, Torus, and Outflow Survey (GATOS). VII. The 20–214 μm Imaging Atlas of Active Galactic Nuclei Using SOFIA
    We present a 19.7–214 μm imaging atlas of local (4–181 Mpc; median 43 Mpc) active galactic nuclei (AGN) observed with FORCAST and HAWC+ on board the SOFIA...

    The huge (but forgotten) population of weak line galaxies in the SDSS: AGN or just retired galaxies
    This talk is divided into two related parts. First, we will call your attention to a basic, but often overlooked worrying fact, and presents ways of dealing...

    The importance of warm, AGN-driven outflows in rapidly evolving galaxies in the local universe
    Although there is increasing speculation that the evolution of galaxy bulges may be regulated by AGN-induced outflows associated with the growth of the central...

    The interplay between local and global properties in galaxies
    We summarize here some of the results reviewed recently by Sanchez (2020) and Sanchez et al. (2021), comprising the advances in the comprehension of galaxies in...
