R. (2023)
    We present the discovery and extensive follow-up of a remarkable fast-evolving optical transient, AT 2022aedm, detected by the Asteroid Terrestrial impact Last Alert Survey (ATLAS). In the ATLAS o band, AT 2022aedm exhibited ...
  • An outflow powers the optical rise of the nearby, fast-evolving tidal disruption event AT2019qiz 
    Nicholl, M.; Wevers, T.; Oates, S. R.; Alexander, K. D.; Leloudas, G.; Onori, F.; Jerkstrand, A.; Gomez, Sebastian; Campana, S.; Arcavi, I.; Charalampopoulos, P.; Gromadzki, M.; Ihanec, N.; Jonker, P.

K.; Cannizzaro, G.; Chen, T. -W; Dennefeld, M.; Galbany, L.; González-Gaitán, S.; Hosseinzadeh, Griffin; Inserra, C.; Irani, I.; Kuin, P.; Müller-Bravo, T.; Pineda, J.; Ross, N. P.; Roy, R.; Smartt, S. J.; Smith, K. W.; Tucker, B.; Wyrzykowski, L.; Young, D. R. (2020)
    At 66-=Mpc, AT2019qiz is the closest optical tidal disruption event (TDE) to date, with a luminosity intermediate between the bulk of the population and the faint-and-fast event iPTF16fnl. Its proximity allowed a very early ...
  • The tidal disruption event AT 2018hyz - I. Double-peaked emission lines and a flat Balmer decrement 
    Short, P.; Nicholl, M.; Lawrence, A.; Gomez, Sebastian; Arcavi, I.; Wevers, T.; Leloudas, G.; Schulze, S.; Anderson, J. P.; Berger, Edo; Blanchard, P. K.; Burke, J.; Segura, N.

Andrew; Ihanec, N.; Inserra, C.; Kankare, E.; Maguire, K.; McCully, C.; Müller Bravo, T. E.; Onori, F.; Sollerman, J.; Young, D. R. (2020)
    We present results from spectroscopic observations of AT 2018hyz, a transient discovered by the All-Sky Automated Survey for Supernova survey at an absolute magnitude of M<SUB>V</SUB> ˜ -20.2 mag, in the nucleus of a ...
