    Light scalar field constraints from gravitational-wave observations of compact binaries

    No full text
    Scalar-tensor theories are among the simplest extensions of general relativity. In theories with light scalars, deviations from Einstein's theory of gravity are determined by the scalar mass m(s) and by a Brans-Dicke-like coupling parameter omega(BD). We show that gravitational-wave observations of nonspinning neutron star-black hole binary inspirals can be used to set lower bounds on omega(BD) and upper bounds on the combination m(s)/root omega(BD). We estimate via a Fisher matrix analysis that individual observations with signal-to-noise ratio rho would yield (m(s)/root omega(BD))(rho/10) less than or similar to 10(-15), 10(-16), and 10(-19) eV for Advanced LIGO, ET, and eLISA, respectively. A statistical combination of multiple observations may further improve these bounds

    Lizzo “Truth Hurts” Co-Author Allegations

    No full text
    Famous recording artist, Lizzo, filed a preemptive lawsuit on October 23rd, 2019 to disprove allegations that Justin and Jeramiah Raisen and Justin “Yves” Rothman deserve author credit for her song, “Truth Hurts.”Lizzo is seeking a declaratory judgment that the alleged authors have no interest in the copyright or right to share profits. The Raisens and Rothman claim that the lyric “I just took a DNA test, turns out I’m 100% that bitch”, which originated from a popular internet meme, was a part of an unreleased demo, which Lizzo recorded at the Raisen’s studio, and on the final track. Lizzo claims that Rothman believes that she will pay him to stop making accusations against her, simply because he was present at a writing session for the demo track.

    Justin Martyr et le dialogue interreligieux contemporain

    No full text
    Cet article examine la crédibilité et la pertinence du rôle conféré à Justin Martyr dans le dialogue interreligieux contemporain. En effet, le concept du Logos spermatikos qu’il a introduit dans la théologie chrétienne est reconnu depuis Vatican II comme la justification de l’ouverture vis-à-vis des religions non chrétiennes. En examinant le dialogue pratiqué par Justin en personne, l’auteur de cet article parvient à la conclusion que l’ouverture des chrétiens engagés dans le dialogue interreligieux contemporain va au-delà de celle de Justin.This article examines the credibility and relevance of the role Justin Martyr is accredited with in the contemporary interreligious dialogue. In fact, the concept of Logos spermatikos he introduced into the Christian theology is acknowledged since Vatican II as the justification of the openness towards the non-Christian religions. While examining the dialogue practiced by Justin himself, the author of this article reaches the conclusion that the open mindedness of Christians involved in the contemporary interreligious dialogue goes beyond the one of Justin

    Inconsistencies between chemistry–climate models and observed lower stratospheric ozone trends since 1998

    No full text
    The stratospheric ozone layer shields surface life from harmful ultraviolet radiation. Following the Montreal Protocol ban on long-lived ozone-depleting substances (ODSs), rapid depletion of total column ozone (TCO) ceased in the late 1990s, and ozone above 32 km is now clearly recovering. However, there is still no confirmation of TCO recovery, and evidence has emerged that ongoing quasi-global (60∘ S–60∘ N) lower stratospheric ozone decreases may be responsible, dominated by low latitudes (30∘ S–30∘ N). Chemistry–climate models (CCMs) used to project future changes predict that lower stratospheric ozone will decrease in the tropics by 2100 but not at mid-latitudes (30–60∘). Here, we show that CCMs display an ozone decline similar to that observed in the tropics over 1998–2016, likely driven by an increase in tropical upwelling. On the other hand, mid-latitude lower stratospheric ozone is observed to decrease, while CCMs that specify real-world historical meteorological fields instead show an increase up to present day. However, these cannot be used to simulate future changes; we demonstrate here that free-running CCMs used for projections also show increases. Despite opposing lower stratospheric ozone changes, which should induce opposite temperature trends, CCMs and observed temperature trends agree; we demonstrate that opposing model–observation stratospheric water vapour (SWV) trends, and their associated radiative effects, explain why temperature changes agree in spite of opposing ozone trends. We provide new evidence that the observed mid-latitude trends can be explained by enhanced mixing between the tropics and extratropics. We further show that the temperature trends are consistent with the observed mid-latitude ozone decrease. Together, our results suggest that large-scale circulation changes expected in the future from increased greenhouse gases (GHGs) may now already be underway but that most CCMs do not simulate mid-latitude ozone layer changes well. However, it is important to emphasise that the periods considered here are short, and internal variability that is both intrinsic to each CCM and different to observed historical variability is not well-characterised and can influence trend estimates. Nevertheless, the reason CCMs do not exhibit the observed changes needs to be identified to allow models to be improved in order to build confidence in future projections of the ozone layer.Atmospheric Remote Sensin
