VizieR Online Data Catalog: Follow-up observations of SNIa ASASSN-14lp (Shappee+, 2016)
Abstract
The All-sky Automated Survey for SuperNovae (ASAS-SN, or "Assassin"; Shappee et al. 2014ApJ...788...48S) scans the entire extragalactic sky in both the northern and southern hemispheres roughly once every 2-3 nights in the V band to depths of 16.5-17.3mag depending on lunation (Shappee et al. 2016, in preparation). We discovered a new source (ASASSN-14lp; V~14.9mag) on 2014 December 9.61 (JDtdisc=2457001.112) at RA=12:45:09.10, DE=-00:27:32.5 (J2000). There are no pre-explosion images of this site available in the Hubble Space Telescope (HST) Archive. Previous observations were obtained by ASAS-SN 1.25, 7.98, 10.98, 11.97, 15.96, and 18.96 days before discovery (see Table 1 and Figure 1 for details). The second set of prediscovery images were obtained by K. Itagaki from 2014 November 13 to 2015 January 09 at the Itagaki Astronomical Observatory, Japan.
After the detection of ASASSN-14lp, we began a multiwavelength, ground- and space-based follow-up campaign from the X-ray to the near-infrared (NIR) wavelengths. Swift/UVOT observations were obtained in V (5468Å), B (4392Å), U (3465Å), UVW1 (2600Å), UVM2 (2246Å), and UVW2 (1928Å). These observations span more than 30days. Optical ground-based images were obtained with the LCOGT 1m network of telescopes (gri), the 2m Liverpool telescope (LT) (gri), and the 40-inch Swope telescope (ugri) as part of the Carnegie Supernova Project II (CSPII; Hsiao et al. 2013ApJ...766...72H). We obtained an extensive sample of low- and medium-resolution optical spectra of ASASSN-14lp spanning more than 3 months between 2014 December 10 and 2015 March 16 (see table 2).
