Orphan optical flare as SOSS emission afterglow, localization in time
V. Lipunov, V. Kornilov, K. Zhirkov +24
We report on MASTER optical observations of an afterglow-like optical and X-ray transient AT2021lfa/ZTF21aayokph. We detected the initial steady brightening of the transient at 7σ…
Three-stage Collapse of the Long Gamma-Ray Burst from GRB 160625B Prompt Multiwavelength Observations
V. M. Lipunov, V. A. Sadovnichy, M. I. Panasyuk +37
This article presents the early results of synchronous multiwavelength observations of one of the brightest gamma-ray bursts (GRBs) GRB 160625B with the detailed continuous fast op…
Probing into emission mechanisms of GRB 190530A using time-resolved spectra and polarization studies: Synchrotron Origin?
Rahul Gupta, S. Gupta, T. Chattopadhyay +47
Multi-pulsed GRB 190530A, detected by the GBM and LAT onboard \fermi, is the sixth most fluent GBM burst detected so far. This paper presents the timing, spectral, and polarimetric…
Optical Observations Reveal Strong Evidence for High Energy Neutrino Progenitor
V. M. Lipunov, V. G. Kornilov, K. K. Zhirkov +32
We present the earliest astronomical observation of a high energy neutrino error box in which its variability was discovered after high-energy neutrinos detection. The one robotic…
Multiwavelength observations of GRB 140629A. A long burst with an achromatic jet break in the optical and X-ray afterglow
Y. -D. Hu, S. R. Oates, V. M. Lipunov +31
We investigate the long GRB140629A through multiwavelength observations, which cover optical, infrared and X-rays between 40s and 3yr after the burst, to derive the properties of t…
MASTER optical detection of the first LIGO/Virgo neutron stars merging GW170817
V. M. Lipunov, E. Gorbovskoy, V. G. Kornilov +30
Following the reported discovery of the gravitational-wave pulse GW170817/ G298048 by three LIGO/Virgo antennae (Abbott et al., 2017a), the MASTER Global Robotic Net telescopes obt…
MASTER OT J004207.99+405501.1/M31LRN 2015 Luminous Red Nova in M31: Discovery, Light Curve, Hydrodynamics, Evolution
V. M. Lipunov, S. Blinnikov, E. Gorbovskoy +18
We report the discovery and multicolor (VRIW) photometry of a rare explosive star MASTER OT J004207.99+405501.1 - a luminous red nova - in the Andromeda galaxy M31N2015-01a. We use…
MASTER optical polarization variability detection in the Microquasar V404 Cyg/GS2023+33
Vladimir M. Lipunov, E. Gorbovskoy, V. Kornilov +23
On 2015 June 15 the Swift space observatory discovered that the Galactic black hole candidate V404 Cyg was undergoing another active X-ray phase, after 25 years of inactivity (Bart…
First Gravitational-Wave Burst GW150914: Part II. MASTER Optical Follow-Up Observations
V. M. Lipunov, V. Kornilov, E. Gorbovskoy +33
The Advanced LIGO observatory recently reported the first direct detection of gravitational waves predicted by Einstein (1916). We report on the first optical observations of the G…
Discovery of an unusual bright eclipsing binary with the longest known period: TYC 2505-672-1 / MASTER OT J095310.04+335352.8
V. Lipunov, E. Gorbovskoy, V. Afanasiev +16
We report on the MASTER Global Robotic Net discovery of an eclipsing binary, MASTER OT J095310.04+335352.8, previously known as unremarkable star TYC 2505-672-1, which displays ext…
