    The road to matrix mechanics: II. Ladenburg’s quantum interpretation of optical dispersion
    This paper reviews Ladenburg’s development of the phenomenological theory of radiative transitions between the stationary states of an atom put forward by...

    The Robotic Multiobject Focal Plane System of the Dark Energy Spectroscopic Instrument (DESI)
    A system of 5020 robotic fiber positioners was installed in 2019 on the Mayall Telescope, at Kitt Peak National Observatory. The robots automatically retarget...

    The role of active galactic nucleus feedback on the evolution of dwarf galaxies from cosmological simulations: Supermassive black holes suppress star formation in low-mass galaxies
    Aims. Recent observational studies suggest that feedback from active galactic nuclei (AGNs) may play an important role in the formation and evolution of dwarf...

    The Role of Asymmetries in Thermal Nonequilibrium
    Thermal nonequilibrium (TNE) is a fascinating situation that occurs in coronal magnetic flux tubes (loops) for which no solution to the steady-state fluid...

    The Role of Bars in AGN Fueling in Disk Galaxies Over the Last Seven Billion Years
    We present empirical constraints on the influence of stellar bars on the fueling of active galactic nuclei (AGNs) out to z = 0.84 using a sample of X-ray...
  • Publication
    The role of cooling induced by mixing in the mass and energy cycles of the solar atmosphere
    In many astrophysical systems, mixing between cool and hot temperature gas/plasma through Kelvin-Helmholtz-instability-driven turbulence leads to the formation...

    The Role of Environment in Galaxy Evolution in the SERVS Survey. I. Density Maps and Cluster Candidates
    We use photometric redshifts derived from new u-band through 4.5 μm Spitzer IRAC photometry in the 4.8 deg 2 of the XMM-LSS field to construct surface density...

    The Role of Evolutionary Age and Metallicity in the Formation of Classical Be Circumstellar Disks. II. Assessing the Evolutionary Nature of Candidate Disk Systems
    We present the first detailed imaging polarization observations of six SMC and six LMC clusters, known to have large populations of B-type stars that exhibit...

    The role of grain size in active galactic nuclei torus dust models
    Context. Active galactic nuclei (AGN) are surrounded by dust within the central parsecs. The dusty circumnuclear structures, referred to as the torus, are...
