We have gathered optical photometry data from the literature on a large sample of Swift-era gamma-ray burst (GRB) afterglows including GRBs up to September 2009, for total 76 GRBs, and present an additional three pre-Swift not included in earlier sample. Furthermore, we publish 840 new points 42 GRB afterglows, sets 050319, 050408, 050802, 050820A, 050922C, 060418, 080413A 080810. analyzed light curves all derived spectral energy distributions with best quality, allowing us estimate host...
The quasar 3C 279 was the target of an extensive multiwavelength monitoring campaign from 2006 January through April. An optical-IR-radio by Whole Earth Blazar Telescope (WEBT) collaboration organized around target-of-opportunity X-ray and soft γ-ray observations with Chandra INTEGRAL in mid-January, additional coverage RXTE Swift XRT. In this paper we focus on results WEBT campaign. source exhibited substantial variability optical flux spectral shape, a characteristic timescale few days....
We use a sample of 19 Gamma Ray Bursts (GRBs) that exhibit single-peaked optical light curves to test the standard fireball model by investigating relationship between time onset afterglow and temporal rising index. Our includes GRBs X-ray flashes for which we derive wide range initial Lorentz factors ($40 < \Gamma 450$). Using plausible parameters typical frequency forward shock is expected lie close band; within this low framework, data constrain $\epsilon_e$ show values derived from early...
We present a comprehensive analysis of 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 BOOTES telescopes when the still radiating in gamma-ray band. Nearly 200 s observations were obtained simultaneously from optical, X-ray to gamma-ray, which makes it one exceptional cases study broadband spectral energy distribution across 6 orders magnitude during phase. By fitting time resolved spectra, we clearly...
We present multiwavelength (optical/near infrared/millimetre) observations of a short duration gamma-ray burst detected by Swift (GRB 050509b) collected between 0 seconds and ∼18.8 days after the event.No optical, near infrared or millimetre emission has been in spite well localised X-ray afterglow, confirming elusiveness events.We also discuss possibility being located cluster galaxies at z = 0.225 beyond.In former case, spectral energy distribution neighbouring, potential host galaxy,...
FTIR spectroscopy in reflection mode combined with a focal plane array (FPA) detector was employed for high-throughput screening of activity catalysts n-pentane hydroisomerization. The reactor system evaluated using reference Pt-MOR and γ-alumina known catalytic activity. By the setup, higher degree parallelization possible, as compared to previous reports, which transmission cells had been used. 49-channel parallel combination FPA-IR optical setup able provide reliable information about...
We present a discovery and observation of an extraordinarily bright prompt optical emission the GRB 060117 obtained by wide-field camera atop robotic telescope FRAM Pierre Auger Observatory from 2 to 10 minutes after GRB. found rapid average temporal flux decay alpha = -1.7 +- 0.1 peak brightness R 10.1 mag. Later observations other instruments set strong limit on radio transient fluxes, unveiling unexpectedly further decay. interpretation featuring relatively steep electron-distribution...
The LSST Camera science sensor array will incorporate 189 large format Charge Coupled Device (CCD) image sensors. Each CCD include over 16 million pixels and be divided into equally sized segments each segment read through a separate output amplifier. goals of the project require sensors with state art performance in many aspects. broad survey wavelength coverage requires fully depleted, 100 micrometer thick, high resistivity, bulk silicon as imager substrate. Image quality requirements...
BART is a small remote controlled robotic CCD telescope, devoted to rapid observation of prompt gamma ray burst transients. During its operation since early 2001, it had three observations with world‐competitive response time. The constraints object magnitude were estimated and published in GCN circulars. Telescope located Astronomical Institute the Czech Academy Sciences Ondřejov. This poster describes new control system, named RTS2, which has been service February 2003.
RTS2, or Remote Telescope System, 2nd Version, is an integrated package for remote telescope control under the Linux operating system. It designed to run in fully autonomous mode, picking targets from a database table, storing image meta data database, processing images and their WCS coordinates offering Virtual-Observatory enabled access them. currently running on various setups world-wide. For of devices manufacturers we developed abstract device layer, enabling all possible combinations...
FRAM—F/(Ph)otometric Robotic Atmospheric Monitor is one of the atmospheric monitoring instruments at Pierre Auger Observatory in Argentina. FRAM an optical telescope equipped with CCD cameras and photometer, it automatically observes a set selected standard stars. Primarily, observations are used to obtain wavelength dependence light extinction. also able observe secondary astronomical targets, namely detection counterparts gamma‐ray bursts has already proven be successful. Finally,...
RTS2 is an open source observatory manager. It was written from scratch in the C++ language, with portability and modularity mind. Its driving requirements originated quick follow-ups of Gamma Ray Bursts. After some years development it now used to carry tasks originally not intended carry. This article presents current status code. focuses on describing strategies which worked as well things failed deliver expected results.
Future wide field astronomical surveys, like Large Synoptic Survey Telescope (LSST), require photometric precision on the percent level. The accuracy of sensor calibration procedures should match these requirements. Pixel size variations found in CCDs from different manufacturers are source systematic errors flat procedure. To achieve required to meet most demanding science goals this effect be taken into account. study pixel area was performed for fully depleted, thick produced a technology...
<i>Aims. <i/>We present multiwavelength observations of one the most distant gamma-ray bursts detected so far, GRB 080913. Based on these observations, we consider whether it could be classified as a short-duration and discuss implications for progenitor nature energy extraction mechanisms.<i>Methods. <i/>Multiwavelength X-ray, near IR millimetre were made between 20.7 h ~16.8 days after event.<i>Results. <i/>Whereas very faint afterglow was seen at 3.5m CAHA telescope in nIR, X-ray clearly...
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 galaxy of GRB 130606A, a high-z event, context population GRBs. have obtained multiwavelength observations from radio to gamma-ray, concentrating particularly on X-ray evolution well optical photometric spectroscopic data analysis. With initial Lorentz bulk factor range Γ_0 ~ 65-220, afterglow can be explained by...
The AGILE gamma-ray burst GRB 080514B is the first detected to have emission above 30 MeV and an optical afterglow. However, no spectroscopic redshift for this known. We report on our ground-based optical/NIR millimeter follow-up observations of event at several observatories, including multi-channel imager GROND La Silla, supplemented by Swift UVOT XRT data. spectral energy distribution (SED) afterglow found decline sharply bluewards UV bands, which can be utilized in estimating redshift....
Four years of BOOTES-1B GRB follow-up history are summarised for the first time in form a table. The successfully followed events described case by case. Further, data used to show trigger rate Spain on per-year basis, resulting an estimate 18 triggers and about 51 h telescope per year real triggers. These numbers grow 22 77 if we include also GRBs observable within 2 hours after trigger.
