VizieR Online Data Catalog: Follow-up of candidate counterparts of S190814bv (Andreoni+, 2020)
Abstract
S190814bv was considered a suitable candidate for the Dark Energy Camera (DECam) follow-up under the NOAO program ID 2019B-0372 (PI Soares-Santos), which conducts observations of binary BH mergers. The first exposure was taken roughly 7hr after the merger at UTC 2019 August 15 06:32:43. Data were acquired on six distinct Chilean calendar nights (2019 August 14, 2019 August 15, 2019 August 16, 2019 August 17, 2019 August 20, and 2019 August 30), lasting from 1.5 to 4.5hr each night. Figure 1 shows the locations of the DECam exposures. See Section 3.
The photometric evolution of the most promising counterpart candidates was monitored using the optical imaging component of the Infrared-Optical suite of instruments (IO:O) on the 2m Liverpool Telescope (LT) at Observatorio del Roque de los Muchachos. Optical photometric follow-up data were also acquired using the Las Cumbres Observatory (LCO) telescope network under proposal ID 2019B-0244 (PI Coughlin). At infrared wavelengths we obtained photometry using the Wide-field Infrared Camera (WIRC) on the Palomar 200-inch Hale telescope (P200). See Section 4.3. The spectroscopic results presented in this paper include data obtained using the Near Infrared Echellete Spectrometer (NIRES) and the Low Resolution Imaging Spectrometer (LRIS) at the W. M. Keck Observatory. We observed three potential candidates with the 10.4m Gran Telescopio de Canarias (GTC; PI A. Castro-Tirado), located at the observatory of Roque de los Muchachos in La Palma (Canary Islands, Spain), equipped with the Optical System for Imaging and low-intermediate-Resolution Integrated Spectroscopy (OSIRIS). Spectroscopy of one candidate of interest was also obtained with the 10m Southern African Large Telescope (SALT) equipped with the Robert Stobie Spectrograph (RSS). See Section 4.3.
