VizieR Online Data Catalog: Type Ic SN2018gep phot. & sp. follow-up (Pritchard+, 2021)
Abstract
SN 2018gep/ZTF18abukavn was first discovered on UT 03:55:17 2018 September 09 (JD=2458370.6634) by Ho+ (2018TNSTR1357....1H) as part of the partnership ZTF survey (Bellm+ 2019PASP..131a8002B).
The ZTF public survey observed SN 2018gep between 2018 September 8 and 28 in the r-ZTF and g-ZTF filters. The Global Supernova Project (GSP) obtained additional Las Cumbres Observatory (LCO) BVgri-band follow-up data with the Sinistro and Spectral cameras on 1m and 2m telescopes, respectively. Science observations were taken between 2018 September 22 and 2018 October 30 with template photometry taken between 2019 January 22 and 26. Additional photometric observations were collected with the 0.6/0.9m Schmidt telescope at Piszkesteto Mountain Station of Konkoly Observatory, Hungary, using the 4kx4k FLI CCD equipped with Johnson-Cousins-Bessel BVRI filters. Observations with the Neil Gehrels Swift Observatory Ultra-Violet/Optical Telescope began on 14:02:56 2018 September 9 (~0.5day after discovery) using three optical (u, b, v) and three UV filters (uvw2, uvm2, uvw1: λc=1928, 2246, 2600Å, respectively. Regular observations continued through 2018 October 3 with a final observation obtained on 2018 October 29. We obtained optical spectroscopy of the SN as well as its host galaxy and list the journal of our spectroscopic observations in Table 2. Additional observations of the location of SN 2018gep and its host galaxy were obtained by two different telescopes at 1.5-2 months after the explosion. One was obtained via Director's Discretionary Time (PI: Bensch) using the Potsdam MultiAperture Spectrophotometer (PMAS), which is an IFU instrument, mounted on the 3.5m telescope at the Centro Astronomico Hispano en Andalucia (CAHA). The other was with the Low-Resolution Imaging Spectrometer (LRIS) at the 10m W. M. Keck Observatory on Maunakea, Hawaii, as part of the LCO-GSP follow-up program (PI: Valenti), using a long-slit aperture. See Section 2.3. (3 data files).- Publication:
