Most single photon emitters in hexagonal boron nitride has been identified as carbon-based defects. These defects, when forming a donor-acceptor pair have spin $S\leq \frac{1}{2}$. By means of density functional calculations, we show that two non-adjacent carbon substitutional defects the same type (i.e. C$_\mathrm{B}$-C$_\mathrm{B}$, and C$_\mathrm{N}$-C$_\mathrm{N}$), can triplet ground state. In particular, one such zero phonon line energy 2.5 eV, its state is nearly 0.5 eV more stable...

The Latin American Giant Observatory (LAGO) is an extended cosmic ray observatory composed by a network of water-Cherenkov detectors spanning over different sites located at significantly altitudes (from sea level up to more than $5000$\,m a.s.l.) and latitudes across America, covering huge range geomagnetic rigidity cut-offs atmospheric absorption/reaction levels. This detection designed measure the temporal evolution radiation flux ground with extreme detail. LAGO project mainly oriented...
The LAGO project is a recent collaboration that comes from the association of latin american astroparticle researchers. It started in 2005 and it was designed to survey high-energy component GRBs. present work describes construction initial testing three WCD prototypes, one located Riobamba at 2784 m.a.s.l., two Quito, Ecuador 2400 2817 m.a.s.l. respectively. We use commercial water tank low cost accessories build each detector, which will be later installed high altitude mountain sites...

The Magnetic Data Acquisition System (MAGDAS) was installed in the protected Jerusalem Park Malchingui-Ecuador October of 2012, under joint collaboration between Kyushu University Japan and Quito Astronomical Observatory National Polytechnic School Ecuador. In this paper, we describe installation process present preliminary data obtained with MAGDAS equipment. behavior four components, D, H, Z F allow us to see importance having Ecuador station where magnetic field has not been...
Abstract In our study, we analyze four peculiar Gamma-Ray Bursts (GRBs), namely GRB070724A, GRB070429B, GRB090426, and GRB120804A, all detected by the Swift space telescope. The focus of investigation lies in evaluating temporal estimators, such as emission time spectral lag third GRB catalog sample. Our findings reveal that calculated estimators offer diverse insights into classification examined GRBs, hinting at distinctive nature these events. This suggests GRBs can be considered...

Water Cherenkov Detectors (WCDs), which are part of the LAGO experimental array, being built in cities Riobamba, Quito and Cumbaya Ecuador. In order to increase sensitivity efficiency these devices, it is necessary ensure that water used as radiator media absorbs low possible UV light due incident particles produced by effect. To do this, we a device allows us measure attenuation length directly. samples purified different techniques analyzed. Some characteristics like absorbance, refractive...
Abstract The canonical classification of GRBs establishes two types bursts, long and short. Although an intermediate class was suggested, its existence is not yet conclusive. In the present work, we explore temporal in burst frame, because recent years statistics bursts with known redshifts has increased. We studied a sample Swift to determine three different time estimators: autocorrelation functions, emission times duration times. order look for subclass GRBs, distribution cosmologically...
Gamma-ray Bursts (GRBs) are one of the most promising tools in study cosmology. The luminosity, energy, light curve parameters and spectral measures could yield to calibration standard candles Universe. Nevertheless, cosmological non-cosmological effects not well understood. Aiming clarify possible effects, we started autocorrelation function (ACF) a sample GRBs with known redshift combined band Swift (15–150 keV) Suzaku (50 keV–5 Mev) satellites. We first confirmed bimodal distribution...
