Detectability of kilonovae in optical surveys: post-mortem examination of the LVC O3 run follow-up. WebWe present results from a systematic selection of tidal disruption events (TDEs) in a wide area (4800 deg2) g+R band experiment by the Intermediate Palomar Transient Factory (iPTF) with a rolling cadence of 1 and 3 days. We use photometric selection criteria to down select from a total of 493 nuclear transients detected during the experiment to a sample … painted snail shells

WebWe report multi-wavelength observations and characterization of the ultraluminous transient AT 2024lwx (ZTF20abrbeie; aka “Barbie”) identified in the alert stream of the Zwicky … WebJul 11, 2024 · One of the known changing-look quasars (CLQs), iPTF16bco (Gezari2024), was caught “turning-on" in the iPTF survey into a broad-line quasar from a low-ionization … WebJul 11, 2024 · These changes usually occur on timescales of years, but recently Gezari et al. reported on iPTF16bco, which showed a more rapid (≲1 yr) change of a LINER to a broad-line quasar. Several explanations of these dramatic changes have been proposed, including obscuration by passing dust or gas clouds and accretion rate changes (MacLeod et al. … painted sneakers custom
