After the Storm

illustratorThe Mediterranean region has faced a significant number of challenges that have stemmed from turbulent events taking place on its Southern shores: conflicts and instability, the migration crisis, disruptions of regional value chains, souring regional relations, and foreign power interferences that have severely affected the region. The Covid-19 pandemic wreaked havoc on the Southern Mediterranean, but the health crisis had ambiguous effects on the underlying economic, social, and political trends of the region. It has exposed and exacerbated much of the previous sources of tension and, obscured many of them as public attention moved towards facing the public health emergency. Will the Covid-19 pandemic spur governments and civil societies to action? Or will it just serve as another smokescreen behind which to hide the region’s longstanding problems

MASTER prompt and follow-up GRB observations

There are the results of gamma-ray bursts observations obtained using the MASTER robotic telescope in 2007 - 2009. We observed 20 error-boxes of gamma-ray bursts this period.The limits on their optical brightnesses have been derived. There are 5 prompt observations among them, obtained at our very wide field cameras. Also we present the results of the earliest observations of the optical emission of the gamma-ray bursts GRB 050824 and GRB 060926.Comment: 10 pages, 2 figure

Master Robotic Net

The main goal of the MASTER-Net project is to produce a unique fast sky survey with all sky observed over a single night down to a limiting magnitude of 19 - 20mag. Such a survey will make it possible to address a number of fundamental problems: search for dark energy via the discovery and photometry of supernovas (including SNIa), search for exoplanets, microlensing effects, discovery of minor bodies in the Solar System and space-junk monitoring. All MASTER telescopes can be guided by alerts, and we plan to observe prompt optical emission from gamma-ray bursts synchronously in several filters and in several polarization planes.Comment: 10 pages, 8 figure

Transient detections and other real-time data processing from wide-field chambers MASTER-VWF

At present time Robotic observatory making is of current importance. Having a large field of view and being able to point at anywhere, Robotic astronomical systems are indispensable when they looking for transients like grb, supernovae explosions, novae etc, as it's impossible in these cases to foresee what you should point you telescope at and when. In work are described prompt GRB observations received on wide-field chambers MASTER-VWF, and also methods of the images analysis and transients classifications applied in real-time data processing in this experiment. For 7 months of operation 6 synchronous observations of gamma-ray burst had been made by MASTER VWF in Kislovodsk and Irkutsk. In all cases a high upper limits have been received (see tabl \ref {tab_grbwf} and fig. \ref {allgrb}).Comment: 21 pages, 21 figure, 2 tables, Advances in Astronomy in pres
