The Extreme Universe Space Observatory on a Super Pressure Balloon 1 (EUSO-SPB1) was launched in 2017 April from Wanaka, New Zealand. plan of this mission opportunity NASA super pressure balloon test flight to circle the southern hemisphere. primary scientific goal make first observations ultra-high-energy cosmic-ray extensive air showers (EASs) by looking down atmosphere with an ultraviolet (UV) fluorescence telescope suborbital altitude (33~km). After 12~days and 4~hours aloft, terminated...
We present the first application of a newly developed hierarchical Bayesian analysis framework for detection point-like sources high-energy neutrinos. verify that we are able to reproduce results standard frequentist approach case NGC 1068, Seyfert II galaxy. Our robust against reasonable variations spectral index prior. However, simulated event rates mainly atmospheric events do not agree with measurements, presumably due binning provided instrument response function. propose an adaptation...
Recently, the IceCube collaboration reported evidence for TeV neutrino emission from several nearby Seyfert galaxies that are intrinsically bright in X-rays, with highest significance found NGC 1068. The fact no gamma rays energy range observed 1068 indicates these neutrinos likely to be produced AGN corona, which is opaque high-energy rays. Based on this assumption, we model of different X-ray properties. We fit resulting spectrum public data and find our fits well. Using result as a...
The field of ultra-high-energy cosmic ray (UHECR) astronomy has been facing an ongoing challenge due to the unknown impact magnetic deflections on observed events. However, with dawn era mass-sensitive data, we would have available information perform UHECR astronomy. To do so, constructing a sophisticated analysis that can accurately reconstruct source parameters will be crucial. In this work, construct Bayesian hierarchical framework utilises spatial, energy, and mass composition infer...
Context . Observations of meteors in the Earth’s atmosphere offer a unique tool for determining flux meteoroids that are too small to be detected by direct telescopic observations. Although these objects routinely observed from ground-based facilities, such as meteor and fireball networks, space-based instruments come with notable advantages have potential achieve broad uniform exposure. Aims In this paper, we describe first observations events Mini-EUSO, very wide field-of-view telescope...
We present constraints on an astrophysical population of neutrino sources imposed by recent data from the IceCube observatory. By using point source search method to model detection sources, our criterion is more sensitive than observation high-energy multiplets for identification. frame problem as a Bayesian hierarchical connect high-level parameters data, allowing us consistently account all relevant uncertainty in assumptions. Our results show that with local density $n_0 \gtrsim 10^{-7}$...
EUSO-Balloon is a pathfinder mission for the Extreme Universe Space Observatory onboard Japanese Experiment Module (JEM-EUSO). It was launched on moonless night of 25th August 2014 from Timmins, Canada. The flight ended successfully after maintaining target altitude 38 km five hours. One part 2.5 hour underflight using helicopter equipped with three UV light sources (LED, xenon flasher and laser) to perform an inflight calibration examine detectors capability measure tracks moving at speed...
Abstract JEM-EUSO is an international program for the development of space-based Ultra-High Energy Cosmic Ray observatories. The consists a series missions which are either under or in data analysis phase. All instruments based on wide-field-of-view telescope, operates near-UV range, designed to detect fluorescence light emitted by extensive air showers atmosphere. We describe simulation software ESAF framework and explain physical assumptions used. present here implementation JEM-EUSO,...
Abstract The complexity of modern cosmic ray observatories and the rich data sets they capture often require a sophisticated software framework to support simulation physical processes, detector response, as well reconstruction analysis real simulated data. Here we present EUSO-Offline framework. code base was originally developed by Pierre Auger Collaboration, portions it have been adopted other collaborations suit their needs. We extended this fulfill requirements Ultra-High Energy Cosmic...
