    “…Pure parallel observing naturally creates a “wedding cake” survey with both wide and ultra-deep tiers, with 5 σ point-source depths at F444W ranging from 27.8–29.4 (ABmag), and with minimized cosmic variance. …”

    Published 2025-01-01
    “…Considering selection biases and measurement uncertainties, we find that the M _BH / M _* ratio evolves as ${\left(1+z\right)}^{0.4{8}_{-0.62}^{+0.31}}$ thus remains essentially constant or exhibits mild evolution up to z  ∼ 2.5. We also see an amount of scatter ( ${\sigma }_{\mu }=0.3{0}_{-0.13}^{+0.14}$ ), similar to the local relation and consistent with low- z studies, and a noncausal cosmic assembly history where mergers contribute to the statistical averaging toward the local relation is still feasible. …”

    On the Formation of Planets in the Milky Way’s Thick Disk by Tim Hallatt, Eve J. Lee

    Published 2025-01-01
    “…Exoplanet demographic surveys have revealed that close-in (≲1 au) small planets orbiting stars in the Milky Way’s thick disk are ∼50% less abundant than those orbiting stars in the Galactic thin disk. …”
