VizieR Online Data Catalog: Radio, opt. & X-ray afterglow obs. of GW170817 (Makhathini+, 2021)
Abstract
We compiled all flux density upper limits from the literature (see references given in Table 2). Flux densities in the case of radio afterglow detections were compiled from Mooley+ (2018ApJ...868L..11M) and references therein, and optical (HST/F606W) afterglow detections were reported in the Fong+ (2019ApJ...883L...1F) reprocessing. See Section 2.
We also report on new data obtained with the Karl G. Jansky Very Large Array (VLA), MeerKAT, the Australia Telescope Compact Array (ATCA), and enhanced Multi Element Remotely Linked Interferometer Network (eMERLIN) radio telescopes between 180 and 780 days post-merger spanning frequencies between 1.2 and 9GHz. We observed GW170817 on 2018 December 18-20 and 2019 September 24-27 with the VLA (PI: Corsi; VLA/18B-204). The Wideband Interferometric Digital Architecture (WIDAR) correlator was used at S band (2-4GHz). See Section 2.1. We observed GW170817 with the ATCA (PI: Dobie, Piro) over four epochs between 2018 November to 2019 September (Table 2). All observations used two bands of 2048MHz centered at 5.5 and 9.0GHz. See Section 2.2. We reprocessed archival upgraded Giant Metrewave Radio Telescope (uGMRT) Band 5 (1.0-1.4GHz) data. See Section 2.3. GW170817 was observed with the MeerKAT telescope over seven epochs between 2018 January 18 and September 2 (see Table 2). The first observation was performed during the AR1 phase using 16 antennas, while remaining observations used the full 64 antenna array. All observations were centered at 1.3GHz using 4096 channels spanning 856MHz and an 8s integration time. see Section 2.4. We observed GW170817 with the eMERLIN array between 2018 January and March with 11 individual runs. Each run had a duration of 5-6hr. Observations were conducted using the C band receiver tuned at frequencies between 4.82 and 5.33GHz. See Section 2.5. Reduced HST images were downloaded from the MAST archive. In Table 2 we report the upper limit from a previously unpublished data set. The observations (PI: N. Tanvir) were carried out with the WFC3/UVIS detector using F814W on 2018 August 08.4 and have a total exposure time of 5.2ks. See Section 2.6. We list the Chandra and XMM-Newton observational data on GW170817 used here for spectral analysis in Table 3. See Section 2.7. (2 data files).- Publication:
