We present ground-based and Swift photometric and spectroscopic observations of the candidate tidal disruption event (TDE) ASASSN-14li, found at the center of PGC043234 (d ' 90 Mpc) by the All-Sky Automated Survey for SuperNovae (ASAS-SN). The source had a peak bolometric luminosity of L ' 1044 ergs s

ASASSN-15oi: a rapidly evolving, luminous tidal disruption event at 216 Mpc (2016, methodology): “As was the case with previous ASAS-SN TDEs, the luminosity evolution inferred from the blackbody fit at early times can be well-described by an exponential L = L0e −(t−t0)/τ (Holoien et al. 2014a, 2016), with bestfit parameters of logL0/L = 10.8 and τ ' 46.5 days for t0 = 57241.6.”
PS16dtm: A Tidal Disruption Event in a Narrow-line Seyfert 1 Galaxy (2017, background): “While the X-ray properties of the host galaxy of ASASSN-14li do not indicate an AGN (Miller et al. 2015), there was a pre-existing radio source detected at a luminosity greater than that expected from star formation alone (Alexander et al. 2016; Holoien et al. 2016).”
The All-Sky Automated Survey for Supernovae (ASAS-SN) Light Curve Server v1.0 (2017, background): “Rarer extragalactic events are tidal disruption events (TDEs), where the majority of the best studied TDEs have been discovered by ASAS-SN (Holoien et al. 2014b, 2016a,b, Brown et al. 2016, 2017a) or are present in ASAS-SN (Brown et al. 2017b), and “changing-look” AGN (Shappee et al. 2014).”
New Physical Insights about Tidal Disruption Events from a Comprehensive Observational Inventory at X-Ray Wavelengths (2016, methodology): “For ASASSN15oi which was classified as an optical/UV TDE by Holoien et al. (2016a), the limited amount of data available make it is difficult to be able to quantify the evolution of the X-ray emission detected and based on the current results it does not decay significantly.”
Revisiting Optical Tidal Disruption Events with iPTF16axa (2017, methodology): “A lower limit of 4.7 was reported for PS1-10jh (Gezari et al. 2015), a lower limit of ∼ 1 was reported for ASASSN-15oi (Holoien et al. 2016a), and we measure a lower limit of 1.9 for PTF09ge from fitting its spectrum obtained from the Double Spectrographmounted on the Palomar 200-inch (P200)…”
