    Probing the roles of orientation and multiscale gas distributions in shaping the obscuration of active galactic nuclei through cosmic time
    The origin of obscuration in active galactic nuclei (AGNs) is still an open debate. In particular, it is unclear what drives the relative contributions to the...

    Revealing the inner workings of the lensed quasar SDSS J1339+1310: Insights from microlensing analysis
    Aims. We aim to unveil the structure of the continuum and broad-emission line (BEL) emitting regions in the gravitationally lensed quasar SDSS J1339+1310 by...

    Revealing the structure of the lensed quasar Q 0957+561. II. Supermassive black hole mass via gravitational redshift
    Aims: We intend to use the impact of microlensing on the Fe III λλ2039−2113 emission line blend along with a measure of its gravitational redshift to estimate...

    The Accretion Mode in Sub-Eddington Supermassive Black Holes: Getting into the Central Parsecs of Andromeda
    The inner kiloparsec regions surrounding sub-Eddington (luminosity less than 10 -3 in Eddington units, L Edd) supermassive black holes (BHs) often show a...

    The Black Hole Mass-Color Relations for Early- and Late-type Galaxies: Red and Blue Sequences
    The tight correlations between supermassive black hole (SMBH) mass (M BH) and the properties of the host galaxy have useful implications for our understanding...

    The First Billion Years project: birthplaces of direct collapse black holes
    We investigate the environment in which direct-collapse black holes may form by analysing a cosmological, hydrodynamical simulation that is part of the First...

    The miniJPAS survey: AGN and host galaxy coevolution of X-ray-selected sources
    Studies indicate strong evidence of a scaling relation in the local Universe between the supermassive black hole mass (M BH) and the stellar mass of their host...
