    Published 2022
    “…In order to constrain such models, we compare the hydrodynamical simulations IllustrisTNG and SIMBA, and the semi-analytical model SAG to the empirical results on AGN and SF at cosmic noon (0.75 < z < 2.25) reported in Florez et al. (2020). …”

    Van Allen Probes Observations of Oxygen Ions at the Geospace Plume by Foster, John C, Erickson, Philip J

    Published 2021
    “…We describe Van Allen Probes observations of ionospheric O+ ions at altitudes of 3–6 R[subscript E] in the near vicinity of the geospace plume in the noon and post-noon sector. The temporal variation of warm ion fluxes observed as a function of time on a moving spacecraft is complicated by changing spacecraft position and complex ion drift paths and velocities that are highly sensitive to ion energy, pitch angle and L value. …”

    Milton, Leibniz, and the Measure of Motion by Raman, Shankar

    Published 2017
    “…Milton’s description of the “high capital / Of Satan and his peers,” the aptly named Pan-daemonium, leads to a memorable account of its architect’s expulsion from heaven: Men called him Mulciber; and how he fell From heaven, they fabled, thrown by angry Jove Sheer o’er the Crystal Battlements; from morn To noon he fell, from noon to dewy eve, A summer’s day; and with the setting Sun Dropped from the zenith like a falling Star, On Lemnos the Aegaean Isle: thus they relate, Erring; for he with this rebellious rout Fell long before; nor aught availed him now To have built in heaven high towers; nor did he scape By all his engines, but was headlong sent With his industrious crew to build in hell. …”

    Studies of the F-Region by the Incoherent Backscatter Method by Evans, J. V.

    Published 2015
    “…On the basis of the results obtained to date the conclusions reached are: (a) the scale height of the electron density increases with height, (b) the ion temperature is not very dependent on height, though it does show a marked diurnal variation, (c) the election-to-ion temperature ratio is 1:1 during the hours of darkness, but during the daytime it increases too peak value ~1.6:1 around noon and (d) the scattering cross section for the electrons is close to the expected value when alIowance is made for (c).…”

    Midlatitude TEC enhancements during the October 2003 superstorm by Foster, John C, Rideout, William C

    Published 2018
    “…A large (∼10x) enhancement in dayside TEC was observed over the US mainland during these events as Dst decreased sharply and strong SAPS electric fields eroded the outer reaches of the post‐noon plasmasphere boundary layer (PBL) forming poleward‐streaming plumes of storm enhanced density. …”

    Millstone Hill Thomson Scatter Results for 1967 by Evans, J. V.

    Published 2015
    “…Winter days exhibit a maximum at all levels near noon and a weaker maximum at the layer peak in the early morning (0200 to 0400 EST), while summer days exhibit a maximum near sunset and only a small day-to-night change in density near the layer peak. …”

    High-performance subambient radiative cooling enabled by optically selective and thermally insulating polyethylene aerogel by Leroy, A., Bhatia, Bikramjit S, Kelsall, Colin Clancy, Zhao, Lingling, Zhang, L., Wang, Evelyn N.

    Published 2020
    “…Using an experimental setup that includes the custom-fabricated PEA, we demonstrate a daytime ambient temperature cooling power of 96 W/m2 and passive cooling up to 13°C below ambient temperature around solar noon. This work could greatly improve the performance of existing passive radiative coolers for air conditioning and portable refrigeration applications.…”

    Intraday adaptation to extreme temperatures in outdoor activity by Fan, Yichun, Wang, Jianghao, Obradovich, Nick, Zheng, Siqi

    Published 2024
    “…This activity-depressing effect is larger than previous daily or monthly studies due to intraday activity substitution from noon and afternoon to morning and evening. Intraday adaptation is larger for locations and dates with time flexibility, for individuals more frequently exposed to heat, and for parks situated in urban areas. …”

    Island precipitation enhancement and the diurnal cycle in radiative-convective equilibrium by Cronin, Timothy Wallace, Molnar, Peter H., Emanuel, Kerry Andrew

    Published 2015
    “…Island size affects the magnitude of simulated island rainfall enhancement, the intensity of the convection, and the timing of the rainfall maximum relative to solar noon. A combination of dynamic and thermodynamic mechanisms leads to a monotonic enhancement of domain-averaged tropospheric temperature with increasing fraction of island surface, which may contribute to localization of ascent over the Maritime Continent and its relationship to the Walker Circulation.…”

    Long-term ionospheric cooling: Dependency on local time, season, solar activity, and geomagnetic activity by Zhang, Shun-Rong, Holt, John M.

    Published 2016
    “…This analysis of long‒term Ti trends in the F region over different local times is based on a database of incoherent scatter radar (ISR) observations spanning more than three solar cycles during 1968–2006 at Millstone Hill and represents an extended effort to a prior study focusing on noon‒time only. This study provides important information for understanding the difference between the ISR and other results. …”

    OBSERVATIONAL SELECTION EFFECTS WITH GROUND-BASED GRAVITATIONAL WAVE DETECTORS by Chen, Hsin-Yu, Holz, Daniel E., Katsavounidis, Erotokritos, Essick, Reed Clasey, Vitale, Salvatore

    Published 2017
    “…Both LIGO detectors preferentially collect data during their local night; it is more than twice as likely to be local midnight than noon when both detectors are operating. We discuss these selection effects and how they impact LIGO's observations and electromagnetic (EM) follow-up. …”

    Published 2022
    “…The anthropogenic heat due to indoor air conditioning was found to play a major role in all the processes studied, while the effect of the different land use types was most pronounced during nighttime and least visible near noon. The UHI circulation developed near the central catchment is found to prevent sea breezes from further propagating inland.…”

    “…AXIS will untangle the interactions of winds, radiation, jets, and supernovae with the surrounding interstellar medium across the wide range of mass scales and large volumes driving galaxy evolution and trace the establishment of feedback back to the main event at cosmic noon. This white paper is part of a series commissioned for the AXIS Probe mission concept; additional AXIS white papers can be found at the AXIS website.…”
