We report early optical linear polarization observations of two gamma-ray bursts made with the MASTER robotic telescope network. found minimum polar- ization for GRB150301B to be 8% at beginning initial stage, whereas we detected no GRB150413A either rising branch or after burst reached power-law afterglow stage. This is earliest measurement (in cosmological rest frame) bursts. The primary intent paper discover emission and publish extremely rare (unique) high- quality light curves prompt...
The physical motivations and advantages of the new gamma-observatory TAIGA (Tunka Advanced Instrument for cosmic ray physics Gamma Astronomy) is presented. array a complex, hybrid detector ground-based gamma-ray astronomy energies from few TeV to several PeV as well studies 100 EeV. will include wide angle Cherenkov TAIGA-HiSCORE with ~5 km2 area, net 16 I ACT telescopes (with FOV about 10x10 degree), muon detectors total area up 2000-3000 m2 radio Tunka-Rex.
We report on the MASTER Global Robotic Net discovery of an eclipsing binary, OT J095310.04+335352.8, previously known as unremarkable star TYC 2505-672-1, which displays extreme orbital parameters. The period P=69.1 yr is more than 2.5 times longer that epsilon-Aurigae, previous record holder. light curve characterized by extremely deep total eclipse with a depth 4.5 mag, symmetrically shaped and has duration 3.5 yrs. essentially gray. spectra acquired Russian 6 m BTA telescope both at...
The TAIGA observatory addresses ground-based gamma-ray astronomy at energies from a few TeV to several PeV, as well cosmic ray physics 100 EeV . will be located in the Tunka valley, ∼ 50 km West Lake Baikal. different detectors of grouped 6 arrays measure Cherenkov and radio emission electron muon components atmospheric showers. combination wide angle TAIGA-HiSCORE array 4-m Imaging Atmospheric Telescopes TAIGA-IACT with their FoV 10×10 degrees underground offers very cost effective way...
Abstract The Maser Monitoring Parkes Project (M2P2) is an ongoing project to observe masers towards high-mass star-forming regions (HMSFRs) using the 64 m CSIRO radio telescope, Murriyang. In this paper, we outline and introduce Stokes-I data from first two years of observations. For 63 sightlines observed in identify a total 1 514 individual maser features: 14.4% these (203) 27 show significant variability. Most (160/203) are seen main-line transitions OH at 1665 1667 MHz, but set also...
Connective tissue growth factor (CTGF) is a secreted protein that strongly induced in human and experimental heart failure.CTGF said to be profibrotic; however, the precise function of CTGF unclear.We generated transgenic mice rats with cardiomyocyte-specific overexpression (CTGF-TG).To investigate as fibrosis inducer, we performed morphological gene expression analyses CTGF-TG rat hearts under basal conditions after stimulation angiotensin II (Ang II) or isoproterenol,...
We present the current status of high-energy cosmic-ray physics and gamma-ray astronomy at Tunka Astrophysical Center (AC). This complex is located in Valley, about 50 km from Lake Baikal. Present efforts are focused on construction first stage observatory TAIGA - prototype. (Tunka Advanced Instrument for cosmic ray Gamma Astronomy) designed study gamma rays charged energy range 1013 eV–1018 eV. The array includes a network wide angle timing Cherenkov stations (TAIGA-HiSCORE), each with FOV...
Observations of gamma rays up to several 100 TeV are particularly important spectrally resolve the cutoff regime long-sought Pevatrons, cosmic-ray PeV accelerators. One component TAIGA hybrid detector is TAIGA-HiSCORE timing array, which currently consists 28 wide angle (0.6 sr) air Cherenkov stations distributed on an area 0.25 km2. The HiSCORE concept based (non-imaging) shower front sampling with light. First results presented.
The physical motivations and performance of the TAIGA (Tunka Advanced Instrument for cosmic ray physics Gamma Astronomy) project are presented. observatory addresses ground-based gamma-ray astronomy at energies from a few TeV to several PeV, as well 100 EeV astroparticle physics. pilot complex locates in Tunka valley, ~50 km West southern tip lake Baikal. It includes integrating air Cherenkov TAIGA-HiSCORE array with 120 wide-angle optical stations distributed over on area 1 square kilometer...
In TAIGA Observatory (Tunka Advanced Instrument for cosmic ray physics and Gamma-ray Astronomy) we are commissioning the first Imaging Atmospheric Cherenkov Telescope (IACT). The telescope has an alt-azimuth mount 17-bit shaft encoder each axis, stepper motors used axis control. For pointing calibration of a CCD-camera is installed on dish its position allows to capture simultaneously both camera with LEDs sky observed source. Since October 2017, been operating in tracking mode. this work...
The TAIGA complex-detector is designed to study gamma and cosmic rays in the energy range above 30 TeV. We are developing a novel wide-angle imaging air Cherenkov telescope with SiPM based camera field of view 15–20o an aperture around 1 m2. In this report we present design (optical data acquisition systems), on 1000–1200 SiPMs. prototype such camera, 49 SiPMs, operating at TAIGA's site Tunka valley since September 2019. preliminary results analysis presented.
