GRB 050509b: the elusive optical/nIR/mm afterglow of a short-duration GRB

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 detected in spite of the well localised X-ray afterglow, confirming the elusiveness of the short duration events. We also discuss the possibility of the burst being located in a cluster of galaxies at

or beyond. In the former case, the spectral energy distribution of the neighbouring, potential host galaxy, favours a system harbouring an evolved dominant stellar population (age ~360 Myr), unlike most long duration GRB host galaxies observed so far, i.e. thus giving support to a compact binary merger origin. Any underlying supernova that could be associated with this particular event should have been at least 3 magnitudes fainter than the type Ib/c SN 1998bw and 2.3 mag fainter than a typical type Ia SN.

Reshaping the user experience at the Large Binocular Telescope Observatory (LBTO)

RTS2, or Remote Telescope System, 2nd Version, is an integrated package for remote telescope control under the Linux operating system. It is designed to run in fully autonomous mode, picking targets from a database table, storing image meta data to the database, processing images and storing their WCS coordinates in the database and offering Virtual-Observatory enabled access to them. It is currently running on various telescope setups world-wide. For control of devices from various manufacturers we developed an abstract device layer, enabling control of all possible combinations of mounts, CCDs, photometers, roof and cupola controllers. We describe the evolution of RTS2 from Python-based RTS to C and later C++ based RTS2, focusing on the problems we faced during development. The internal structure of RTS2, focusing on object layering, which is used to uniformly control various devices and provides uniform reporting layer, is also discussed.

GRB follow-up with BOOTES Optical Chapter 5: The Swift Era

BART is a 25 cm aperture, intelligent robotic CCD telescope, devoted for observation of prompt gamma ray burst emission and early afterglow. It’s operating since early 2001. Till now, it responded to many GCN GRB alerts.

Blazars and INTEGRAL

Uniquely designed with two 8.4m mirrors, a 22.8m interferometric baseline, and the collecting area of an 11.8m telescope, the Large Binocular Telescope Observatory (LBTO), has a narrow window of opportunity to exploit its status as the “first” of the ELTs. Prompted by urgency to maximum scientific output during this favorable interval, we undertook a multi-year project to reshape the user experience. The initial stage, implementing a new suite of software to facilitate proposal submission, script creation, binocular planning, and nighttime execution, is nearing completion. Reuse and adaptation of existing software, particularly Gemini Observatory’s cross-platform PIT and OT, proved critical, although as expected, we encountered many challenges presented by our one-of-a-kind binocular design and operations. We hope to leverage our success in the early phases of this project toward further improvement of our science operations model, specifically, augmenting our nighttime operations to include observatory-led observing. We plan to focus this observing mode primarily on instruments that require block scheduling and/or superb and rare conditions such as our newly commissioned GLAO system, ARGOS. In this paper, we outline our workflow, describe lessons learned, and present our resulting software products. We also detail future development toward our ultimate goal, improved efficiency and user interactions throughout every step of the observing experience.

BOOTES is a robotic system, whose primary aim is to observe gamma‐ray burst prompt emission. Since 1998 BOOTES has provided follow‐up observations for more than 70 GRBs; the most important results obtained so far are the detection of an OT in the short/hard GRB 000313 error box, the detection of several optical after‐glow for long/soft GRBs and the non‐detection of optical emission simultaneous to the high energy emission for several GRBs (both long/soft and short/hard events). During the time of operation we have got triggers from CGRO/BATSE, BeppoSAX, HETE‐2, INTEGRAL and Swift. Here we present our early detections of GRB optical emission using the 30 cm Bootes‐1B telescope in the R.V and I‐bands since the launch of Swift.

We refer to analysis of the ESA INTEGRAL satellite data for specific class of active galactic nuclei - blazars. These objects represent promising sources to be observed by INTEGRAL, especially during their active states. Suitable strategy for the future analysis is proposed and discussed.
