Fuegos que no queman en la novela griega antigua y las ordalías en Aquiles Tacio y Heliodoro
2019
La cremación como castigo a los condenados a muerte ya fue utilizada en la Antigüedad. En algunos casos, ciertas personas no se ven afectadas por las llamas a causa de la intervención divina. Se trata de un motivo literario y folklórico que parte del Antiguo Testamento (libro 3 de Daniel) y aparece también en la novela griega antigua, con matices variados. Aquiles Tacio y Heliodoro presentan al final de sus obras sendas ordalías en que los personajes encausados demuestran su inocencia, pero con lecturas bien diferentes en una y otra novela. Cremation as a punishment for those sentenced to death was already used in Antiquity. In some cases, certain people are not affected by the flames becau…

OBSERVATION OF THE TeV GAMMA-RAY SOURCE MGRO J1908+06 WITH ARGO-YBJ
2012
The extended gamma ray source MGRO J1908+06, discovered by the Milagro air shower detector in 2007, has been observed for about 4 years by the ARGO-YBJ experiment at TeV energies, with a statistical significance of 6.2 standard deviations. The peak of the signal is found at a position consistent with the pulsar PSR J1907+0602. Parametrizing the source shape with a two-dimensional Gauss function we estimate an extension \sigma = 0.49 \pm 0.22 degrees, consistent with a previous measurement by the Cherenkov Array H.E.S.S.. The observed energy spectrum is dN/dE = 6.1 \pm 1.4 \times 10^-13 (E/4 TeV)^{-2.54 \pm 0.36} photons cm^-2 s^-1 TeV^-1, in the energy range 1-20 TeV. The measured gamma ray…
Observation of TeV gamma rays from the Cygnus region with the ARGO-YBJ experiment
2012
We report the observation of TeV gamma-rays from the Cygnus region using the ARGO-YBJ data collected from 2007 November to 2011 August. Several TeV sources are located in this region including the two bright extended MGRO J2019+37 and MGRO J2031+41. According to the Milagro data set, at 20 TeV MGRO J2019+37 is the most significant source apart from the Crab Nebula. No signal from MGRO J2019+37 is detected by the ARGO-YBJ experiment, and the derived flux upper limits at 90% confidence level for all the events above 600 GeV with medium energy of 3 TeV are lower than the Milagro flux, implying that the source might be variable and hard to be identified as a pulsar wind nebula. The only statist…

La capilla de la Virgen de Campanar en Valencia: tradición popular erigida en erudita retórica visual
2018
This chapel forms part of the parochial church of Campanar, which belongs to the municipality of Valencia. The Virgen de Campanar (Virgin of Campanar) is an image executed in alabaster, discovered on the subfloor of the church of this place on February 19th, 1596, by some construction workers who were undertaking some remodeling at that time. From that moment forward it began to be worshipped by the masses as a miraculous image. Among its alleged properties we find the mysterious fact that powder from its plaster had miraculous effects: it was taken dissolved in water to cure the sick or to assure a healthy birth for pregnant women, and it even calmed storms at sea if it was thrown into the…

Search for Galactic PeV gamma rays with the IceCube Neutrino Observatory
2013
Gamma-ray induced air showers are notable for their lack of muons, compared to hadronic showers. Hence, air shower arrays with large underground muon detectors can select a sample greatly enriched in photon showers by rejecting showers containing muons. IceCube is sensitive to muons with energies above ~500 GeV at the surface, which provides an efficient veto system for hadronic air showers with energies above 1 PeV. One year of data from the 40-string IceCube configuration was used to perform a search for point sources and a Galactic diffuse signal. No sources were found, resulting in a 90% C.L. upper limit on the ratio of gamma rays to cosmic rays of 1.2 x 10^(-3)for the flux coming from …
Gamma ray sources observation with the ARGO-YBJ detector
2011
In this paper we report on the observations of TeV gamma ray sources performed by the air shower de- tector ARGO-YBJ. The objects studied in this work are the blazar Markarian 421 and the extended galactic source MGROJ1908+06, monitored during 2 years of operation. Mrk421 has been detected by ARGO-YBJ with a statisti- cal significance of 11 standard deviations. The observed TeV emission was highly variable, showing large enhance- ments of the flux during active periods. The study of the spectral behaviour during flares revealed a positive correla- tion of the hardness with the flux, as already reported in the past by the Whipple telescope, suggesting that this is a long term property of the…
