A detailed time-resolved and energy-resolved spectro-polarimetric study of bright GRBs detected by AstroSat CZTI in its first year of operation
Rahul Gupta, S. B. Pandey, S. Gupta +11
The radiation mechanism underlying the prompt emission remains unresolved and can be resolved using a systematic and uniform time-resolved spectro-polarimetric study. In this paper…
Catalog of variable stars in the WD 0009+501 and GRW +708247 fields based on photometric survey data on transiting exoplanets
O. Ya. Yakovlev, A. F. Valeev, G. G. Valyavin +15
We present a catalog of 150 variable stars, including 13 stars with exoplanet candidates. 37 stars were identified as variables for the first time. As a result of a 2.5-year photom…
Revealing characteristics of dark GRB 150309A: dust extinguished or high-z?
A. J. Castro-Tirado, Rahul Gupta, S. B. Pandey +28
Dark GRBs constitute a significant fraction of the GRB population. In this paper, we present the multiwavelength analysis of an intense two-episodic GRB 150309A observed early on t…
Eight exoplanet candidates in SAO survey
O. Ya. Yakovlev, A. F. Valeev, G. G. Valyavin +15
Here we present eight new candidates for exoplanets detected by the transit method at the Special Astrophysical Observatory of the Russian Academy of Sciences. Photometric observat…
Search for LBVs in the Local Volume galaxies: study of four stars in NGC 4449
Y. Solovyeva, A. Vinokurov, A. Sarkisyan +8
We continue to search for LBV stars in galaxies outside the Local Group. In this work, we have investigated four luminous stars in NGC 4449. Multiple spectral observations carried…
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…
