Ho, Manuela Bischetti, Stefano Carniani, Michele Ginolfi, Gareth Jones, Roberto Maiolino, Wiphu Rujopakarn, N. M. Förster Schreiber, Juan M. Espejo Salcedo, L. L. Lee

    Published 2025-01-01
    “…Notably, while the masses of these supermassive black holes (SMBHs) are approximately 1 dex higher than the low-redshift relationship with stellar mass, the closer alignment of SMBH and halo masses with a local relationship may indicate that the early formation of these SMBHs is linked to their dark matter halos, providing insights into the coevolution of galaxies and black holes in the early Universe.…”

    D’Alger à Damas, des auteurs en mal d’archives ? by Ines Horchani

    Published 2014-09-01
    “…In any case, marks from the colonial past are tangible and can resemble black holes, scars, rifts, or stratum… We will show that these authors from an Arab world, not yet completely restored from colonization, make quite variable usage of real archives (academic or non-academic) and also resort to the creation of imaginary archives. …”
