Observational neutrino astronomy can bring information also on particle physics that can not be obtained in other ways. In general this concerns processes at extreme energy and distance scales. Particularly of interest are cosmic accelerators, GUT phase transition remnants and dark matter annihilation. After four years of R&D the ANTARES Collaboration begins the actual construction of a neutrin...

Two independent indirect manifestations of Galactic gamma-ray bursts (GRBs) are considered, whose importance for gamma-ray astronomy will depend on a still poorly known – though astrophysically important – parameter, namely the GRB repetition timescale in a Galaxy like ours. Both phenomena are expected to lead to observational constrains about this timescale. The first one relates to the Compto...

BDB is developed atin the Institute of Astronomy RAS, and contains information on physical and positional parameters of binary stars, belonging to various observational types: visual, spectroscopic, eclipsing, etc. Problems of information aggregation on binaries of various types binaries (obtained from heterogeneous sources of data astronomical catalogues and surveys) aggregation in a uniquefie...

The concept of evaluation gaps captures potential discrepancies between what researchers value about their research, in particular research quality, and metrics measure. existence can give rise to questions the relationship intrinsic extrinsic motivations perform i.e., how field-specific notions quality compete with captured via metrics, consequently manage balancing act values requirements pro...

once the greek astronomy's most worthy masterpiece, ptolemy’s almagest, was translated into arabic, many scientific works were produced in islamic civilization. the genre known as hayʾa, which deals with the cosmological aspect of astronomy, gradually seperated itself from other astronomical branches. while these branches were in relation with each other, their goals were different. comput...

I present a review of nonthermal processes in the large scale structure of the universe. After examining the properties of cosmological shock waves and their role as particle accelerators, I discuss the main observational facts, from radio to γ-ray and describe the processes that are thought be responsible for the observed nonthermal emissions. Finally, I emphasize the important role of γ-ray a...

A fast-turnaround pipeline for realtime data reduction plays an essential role in discovering and permitting follow-up observations to young supernovae and fast-evolving transients in modern time-domain surveys. In this paper, we present the realtime image subtraction pipeline in the intermediate Palomar Transient Factory. By using high-performance computing, efficient database, and machine lea...

Increased access to very large astronomical databases, the use of large format detectors and other developments in observational astronomy have the potential to overwhelm the capacity of most astronomers to analyze data unless new approaches to data reduction are found. This paper reports the initial progress in creating an expert system to assist in the reduction of scientific data. This syste...

Andes Large-area PArticle detector for Cosmic-ray physics and Astronomy (ALPACA) is an international experiment that applies southern very-high-energy (VHE) gamma-ray astronomy to determine the origin of cosmic rays around knee energy region ($10^{15}\, {\rm eV} - 10^{16}\, eV}$). The consists air shower (AS) array with a surface $83, 000\, m}^2$ underground water Cherenkov muon (MD) covering $...
