TL;DR: In this paper, the authors summarize past electromagnetic follow-up efforts as well as the organization and policy of the current EM followup program and compare the four probability sky maps produced for the gravitational-wave transient GW150914, and provide additional details of the EM follow up observations that were performed in the different bands.

TL;DR: In this paper, the authors reported the discovery of the likely IR counterpart to the Anomalous X-ray Pulsar (AXP) 1RXS J1708-4009, based on the combination of Chandra HRC-I Xray position, and deep optical/IR observations carried out from ESO telescopes and the Canada France Hawaii Telescope (CFHT) during 1999-2002.

TL;DR: In this paper, the authors present the results from an ESO/VLT campaign aimed at studying the afterglow properties of the short/hard gamma ray burstGRB070707 Observations were carried out at ten different epochs from ∼ 05 to ∼ 80 days after the event.

TL;DR: In this paper, the authors performed a detailed spectral analysis of four Chandra, three INTEGRAL, and one XMMNewton observations collected over a two week interval after the outburst onset in January 2009.

TL;DR: The sky region including the Chandra position of SGR 1806-20 was monitored in the IR band during 2004, following its increased high energy bursting activity as mentioned in this paper, which provided images of unprecedented quality (FWHM better than 0.1").
