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…
GRB 190919B: Rapid optical rise explained as a flaring activity
Martin Jelínek, Martin Topinka, Sergey Karpov +17
Following the detection of a long GRB 190919B by INTEGRAL (INTErnational Gamma-Ray Astrophysics Laboratory), we obtained an optical photometric sequence of its optical counterpart.…
Exceptionally bright optical emission from a rare and distant ray burst
Gor Oganesyan, Sergey Karpov, Martin Jelínek +19
Long -ray bursts (GRBs) are produced by the dissipation of ultra-relativistic jets launched by newly-born black holes after the collapse of massive stars. Right after the lu…
GRB 140102A: Insight into Prompt Spectral Evolution and Early Optical Afterglow Emission
Rahul Gupta, S. R. Oates, S. B. Pandey +38
We present and perform a detailed analysis of multi-wavelength observations of \thisgrb, an optical bright GRB with an observed reverse shock (RS) signature. Observations of this G…
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…
Transition from Fireball to Poynting-flux-dominated Outflow in Three-Episode GRB 160625B
B. -B. Zhang, B. Zhang, A. J. Castro-Tirado +51
The ejecta composition is an open question in gamma-ray bursts (GRB) physics. Some GRBs possess a quasi-thermal spectral component in the time-resolved spectral analysis, suggestin…
A decade of GRB follow-up by BOOTES in Spain (2003-2013)
Martin Jelínek, Alberto J. Castro-Tirado, Ronan Cunniffe +20
This article covers ten years of GRB follow-ups by the Spanish BOOTES stations: 71 follow-ups providing 23 detections. Follow-ups by BOOTES-1B from 2005 to 2008 were given in the p…
Early optical follow-up of the nearby active star DG CVn during its 2014 superflare
M. D. Caballero-Garcia, V. Simon, M. Jelinek +20
DG CVn is a binary system in which one of the components is an M type dwarf ultra fast rotator, only three of which are known in the solar neighborhood. Observations of DG CVn by t…
Follow-up of X-ray transients detected by SWIFT with COLORES using the BOOTES network
M. D. Caballero-Garcia, M. Jelinek, A. J. Castro-Tirado +4
The Burst Observer and Optical Transient Exploring System (BOOTES) is a network of telescopes that allows the continuous monitoring of transient astrophysical sources. It was origi…
The dark nature of GRB 130528A and its host galaxy
S. Jeong, A. J. Castro-Tirado, M. Bremer +18
We study the dark nature of GRB 130528A through multi-wavelength observations and conclude that the main reason for the optical darkness is local extinction inside of the host gala…
GRB 130606A within a sub-DLA at redshift 5.91
A. J. Castro-Tirado, R. Sánchez-Ramírez, S. L. Ellison +38
Events such as GRB130606A at z=5.91, offer an exciting new window into pre-galactic metal enrichment in these very high redshift host galaxies. We study the environment and host ga…
BOOTES Observation of GRB 080603B
Martin Jelinek, Javier Gorosabel, Alberto J. Castro-Tirado +9
We report on multicolor photometry of long GRB080603B afterglow from BOOTES-1B and BOOTES-2. The optical afterglow has already been reported to present a break in the optical light…
Panchromatic observations of the textbook GRB 110205A: constraining physical mechanisms of prompt emission and afterglow
W. Zheng, R. F. Shen, T. Sakamoto +56
We present a comprehensive analysis of a bright, long duration (T90 ~ 257 s) GRB 110205A at redshift z= 2.22. The optical prompt emission was detected by Swift/UVOT, ROTSE-IIIb and…
Four Years of Realtime GRB Followup by BOOTES-1B (2005-2008)
Martin Jelinek, Alberto J. Castro-Tirado, Antonio de Ugarte Postigo +8
Four years of BOOTES-1B GRB follow-up history are summarised for the first time in the form of a table. The successfully followed events are described case by case. Further, the da…
