Iconic architecture and the culture-ideology of consumerism

This article explores the theoretical and substantive connections between iconicity and consumerism in the field of contemporary iconic architecture within the framework of a critical theory of globalization. Iconicity in architecture is defined in terms of fame and special symbolic/aesthetic significance as applied to buildings, spaces and in some cases architects themselves. Iconic architecture is conceptualized as a hegemonic project of the transnational capitalist class. In the global era, I argue, iconic architecture strives to turn more or less all public space into consumerist space, not only in the obvious case of shopping malls but more generally in all cultural spaces, notably museums and sports complexes. The inspiration that iconic architecture has provided historically generally coexisted with repressive political and economic systems, and for change to happen an alternative form of non-capitalist globalization is necessary. Under such conditions truly inspiring iconic architecture, including existing architectural icons, may create genuinely democratic public spaces in which the culture-ideology of consumerism fades away. In this way, a built environment in which the full array of human talents can flourish may begin to emerge

Multi-messenger Observations of a Binary Neutron Star Merger

International audienceOn 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of $\sim 1.7\,{\rm{s}}$ with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg(2) at a luminosity distance of ${40}_{-8}^{+8}$ Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 $\,{M}_{\odot }$. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at $\sim 40\,{\rm{Mpc}}$) less than 11 hours after the merger by the One-Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ∼10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position $\sim 9$ and $\sim 16$ days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC 4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta
