In 2009, an astronomical pavilion was built here in conjunction with the GAISH Moscow State University, in which a dual robot – the MASTER-400 telescope is currently installed. The MASTER robot telescope is a highly effective tool for searching and studying optical transients. In particular, the optical tracking of gamma-ray bursts.
The wide-field telescope MASTER-400 Tunka is a two-tube aperture (diameter 400 mm, aperture ratio 1: 2.5) system with a total field of view of 8 square degrees, equipped with 16-megapixel cameras, a universal photometer with B, V, R, I filters and polarizers. 2 telescopes are mounted on an ultra-fast mount (speed of guidance and guidance up to 30 degrees/sec), which does not require additional guiding devices. The installation has an additional degree of freedom – in the case of target designation (“alert mode”), the pipes are brought together in parallel, which allows synchronous multi-color photometry of short-lived (seconds) or fast-moving objects. The viewing speed provided by one MASTER-400 complex is 480 square degrees per hour up to 20 magnitude.
All MASTER robotic telescopes of the global network, including the MASTER-Tunka telescope operating at the Moscow State University-ISU Astrophysical Complex at the Tunkinsky Astrophysical Center for Collective Use of Irkutsk State University, are equipped with identical own photometers (two full-frame CCD cameras, B, V filters, R, I Johnson-Bessel systems and two linear polarizers) and are controlled by identical proprietary software. Using identical equipment allows continuous observation of optical transients for 24 hours in identical photometric systems.
Since 2016, the MASTER Global Network of Robot Telescopes has become a world leader in the study of relativistic sources of gravitational-wave bursts LIGO / Virgo (Nature, 2017, 551, 85; Astrophysical Journal Letters. Vol. 848, pp. 12-71, 2017; Astrophysical Journal Letters vol. 850, n. 1, pp. L1, 2017), early optical observations of gamma-ray bursts (Nature, 2017, 547, 425), a leader in the study of intrinsic optical radiation of gamma-ray bursts – the most powerful phenomena in the Universe (Troja, E .; Lipunov, VM et al., Significant and variable linear polarization during the prompt optical flash of GRB 160625B, Nature, Vol. 547, p. 425-427 (2017); Lipunov et al “Smooth Optical Self similar emission of gamma-ray bursts. ”APJ 2017, 845, 52L) and other phenomena of high-energy astrophysics (2 articles in Nature (impact factor 40) and 24 articles in leading journals with impact factor above 5 in 2 years).
The MASTER-400 telescope robot as part of the MASTER Global Robotic Network has now achieved outstanding results, becoming one of the most effective search engines in the world. MASTER telescopes August 17, 2017 independently discovered the optical emission of the kilon (the result of the merger of neutron stars) MASTER OTJ130948.10-232253.3 / SSS17a caused by the decay of superheavy radioactive chemical elements formed in the expanding shell after the merger of neutron stars detected by the gravitational-wave detectors LIGO / Virgo17WGW. In fact, it was these observations that opened up a new science – gravitational-wave astronomy.
