    • Optical observations reveal strong evidence for high-energy neutrino progenitor 

      Lipunov, V.M.; Böttcher, M.; Kornilov, V.G.; Zhirkov, V.; Gorbovskoy, E. (IOP Publishing, 2020)
      We present the earliest astronomical observation of a high-energy neutrino error box of which the variability was discovered after high-energy-neutrino detection. The one robotic telescope of the MASTER global international ...

    • X-ray polarimetry with the Polarization Spectroscopic Telescope Array (PolSTAR) 

      Krawczynski, Henric S.; Böttcher, Markus; Stern, Daniel; Harrison, Fiona A.; Kislat, Fabian F. (Elsevier, 2016)
      This paper describes the Polarization Spectroscopic Telescope Array (PolSTAR), a mission proposed to NASA’s 2014 Small Explorer (SMEX) announcement of opportunity. PolSTAR measures the linear polarization of 3–50 keV ...
