Las tormentas de microsismos como fuentes de pulsaciones geomagnéticas
Se analiza la influencia de las ondas de Rayleigh presentes en las tormentas de microsismos sobre la capa E de la ionosfera como un posible mecanismo para la generación de pulsaciones geomagnéticas. Las ondas acústico-gr ...
A gravitational wave standard siren measurement of the Hubble constant
(Nature Publishing Group, 2017)
On 17 August 2017, the Advanced LIGO(1) and Virgo(2) detectors observed the gravitational-wave event GW170817-a strong signal from the merger of a binary neutron-star system(3). Less than two seconds after the merger, a ...
Multimessenger astronomy with gravitational waves and high-energy neutrinos
(American Physical Society, 2013-10)
Many of the astrophysical sources and violent phenomena observed in our Universe are potential emitters of gravitational waves and high-energy cosmic radiation, including photons, hadrons, and presumably also neutrinos. ...
The gravitational wave radiation of pulsating white dwarfs revisited: The case of BPM 37093 and PG 1159-035
(EDP Sciences, 2006-01)
We compute the emission of gravitational radiation from pulsating white dwarfs. This is done by using an up-to-date stellar evolutionary code coupled with a state-of-the-art pulsational code. The emission of gravitational ...
Real-time earthquake warning for astronomical observatories
Early earthquake warning is a rapidly developing capability that has significant ramifications for many fields, including astronomical observatories. In this work, we describe the susceptibility of astronomical facilities ...
Prospects for Observing and Localizing Gravitational-Wave Transients with Advanced LIGO and Advanced Virgo
We present a possible observing scenario for the Advanced LIGO and Advanced Virgo gravitational-wave detectors over the next decade, with the intention of providing information to the astronomy community to facilitate ...
The electromagnetic counterpart of the binary neutron star merger LIGO/Virgo GW170817. I. discovery of the optical counterpart using the dark energy camera
(IOP Publishing Ltd., 2017)
We present the Dark Energy Camera (DECam) discovery of the optical counterpart of the first binary neutron star merger detected through gravitational-wave emission, GW170817. Our observations commenced 10.5 hr post-merger, ...
