ALMA, ATCA, and Spitzer Observations of the Luminous Extragalactic Supernova SN 1978K

I. A. Smith, S. D. Ryder, R. Kotak +2

Only three extragalactic supernovae have been detected at late times at millimeter wavelengths: SN 1987A, SN 1978K, and SN 1996cr. SN 1978K is a remarkably luminous Type IIn supern…

SS433's jet trace from ALMA imaging and Global Jet Watch spectroscopy: evidence for post-launch particle acceleration

Katherine Blundell, Robert Laing, Steven Lee +1

We present a comparison of Doppler-shifted H-alpha line emission observed by the Global Jet Watch from freshly-launched jet ejecta at the nucleus of the Galactic microquasar SS433…

The luminous host galaxy, faint supernova and rapid afterglow rebrightening of GRB 100418A

A. de Ugarte Postigo, C. C. Thoene, K. Bensch +35

Long gamma-ray bursts give us the chance to study both their extreme physics and the star-forming galaxies in which they form. GRB 100418A, at a z = 0.6239, had a bright optical an…

X-shooter and ALMA spectroscopy of GRB 161023A - A study of metals and molecules in the line of sight towards a luminous GRB

A. de Ugarte Postigo, C. C. Thöne, J. Bolmer +45

Long gamma-ray bursts are produced during the dramatic deaths of massive stars with very short lifetimes, meaning that they explode close to the birth place of their progenitors. D…

SMSS J130522.47-293113.0: a high-latitude stellar X-ray source with pc-scale outflow relics?

G. S. Da Costa, R. Soria, S. A. Farrell +17

We report the discovery of an unusual stellar system, SMSS J130522.47-293113.0. The optical spectrum is dominated by a blue continuum together with emission lines of hydrogen, neut…

Rapidly evolving transients in the Dark Energy Survey

M. Pursiainen, M. Childress, M. Smith +79

We present the results of a search for rapidly evolving transients in the Dark Energy Survey Supernova Programme. These events are characterized by fast light curve evolution (rise…
