¿Geopolíticas de mundos efímeros? La performatividad de los mapas de las Exposiciones Universales y los órdenes mundiales que crearon (Chicago 1893, París 1900 y Nueva York 1939)Geopolíticas de mundos efêmeros? A performatividade dos mapas das exposições universais e as ordens mundiais criadas por eles (Chicago 1893, Paris 1900 e Nova Iorque 1939)Geopolitics of ephemeral worlds?

(Rede Brasileira de História da Geografia e Geografia Histórica, 2019-01)
Les expositions universelles ont été le scénario et, plus encore, le expression, des vicissitudes générales de l´économie mondiale, les tensions géopolitiques et des valeurs culturelles de leur temps. Ces variations ...
GW151226: Observation of Gravitational Waves from a 22-Solar-Mass Binary Black Hole Coalescence
(Amer Physical Soc, 2016-06-15)
We report the observation of a gravitational-wave signal produced by the coalescence of two stellar-mass black holes. The signal, GW151226, was observed by the twin detectors of the Laser Interferometer Gravitational-Wave ...
All-sky search for long-duration gravitational wave transients with initial LIGO
(2016-02-12)
We present the results of a search for long-duration gravitational wave transients in two sets of data collected by the LIGO Hanford and LIGO Livingston detectors between November 5, 2005 and September 30, 2007, and July ...
Effects of data quality vetoes on a search for compact binary coalescences in Advanced LIGO's first observing run
(Iop Publishing Ltd, 2018-03-22)
The first observing run of Advanced LIGO spanned 4 months, from 12 September 2015 to 19 January 2016, during which gravitational waves were directly detected from two binary black hole systems, namely GW150914 and GW151226. ...
Search of the Orion spur for continuous gravitational waves using a loosely coherent algorithm on data from LIGO interferometers
(Amer Physical Soc, 2016-02-17)
We report results of a wideband search for periodic gravitational waves from isolated neutron stars within the Orion spur towards both the inner and outer regions of our Galaxy. As gravitational waves interact very weakly ...
Observation of gravitational waves from a binary black hole merger
(2017-04-01)
Albert Einstein's general theory of relativity, first published a century ago, was described by physicist Max Born as the greatest feat of human thinking about nature.We report on two major scientific breakthroughs involving ...
Comprehensive all-sky search for periodic gravitational waves in the sixth science run LIGO data
(Amer Physical Soc, 2016-08-15)
We report on a comprehensive all-sky search for periodic gravitational waves in the frequency band 100-1500 Hz and with a frequency time derivative in the range of [-1.18; +1.00] x 10(-8) Hz/s. Such a signal could be ...
Properties of the Binary Black Hole Merger GW150914
(Amer Physical Soc, 2016-06-14)
On September 14, 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected a gravitational-wave transient (GW150914); we characterize the properties of the source and its parameters. The data around the ...
Search for continuous gravitational waves from neutron stars in globular cluster NGC 6544
(Amer Physical Soc, 2017-04-19)
We describe a directed search for continuous gravitational waves in data from the sixth initial LIGO science run. The target was the nearby globular cluster NGC 6544 at a distance of approximate to 2.7 kpc. The search ...
