HST Deep Upper Limits Rule Out a Surviving Massive Binary Companion to the Type Ic Supernova 2012fh

Benjamin F. Williams, Emmanouil Zapartas, Ori D. Fox +19

Current explanations of the mass-loss mechanism for stripped-envelope supernovae remain divided between single and binary progenitor systems. Here we obtain deep ultraviolet (UV) i…

The Demographics of Binary Companions to Stripped-Envelope Supernovae: Confronting Observations with Population Synthesis

E. Zapartas, O. D. Fox, J. Su +15

Stripped-envelope supernovae (SESNe) mark the deaths of massive stars without hydrogen-rich envelopes. Most SESNe likely originate from binary systems where a companion stripped th…

The central region of M83: Massive star formation, kinematics, and the location and origin of the nucleus

J. H. Knapen, R. G. Sharp, S. D. Ryder +3

We report new near-IR integral field spectroscopy of the central starburst region of the barred spiral galaxy M83 obtained with CIRPASS on Gemini-S, which we analyse in conjunction…

Examining the Seyfert - Starburst Connection with Arcsecond Resolution Radio Continuum Observations

Seppo Laine, Jari K. Kotilainen, Juha Reunanen +2

We compare the arcsecond-scale circumnuclear radio continuum properties between five Seyfert and five starburst galaxies, concentrating on the search for any structures that could…

Age-dating a star-burst with Gemini/CIRPASS observations of the core of M83

R. G. Sharp, I. R. Parry, S. D. Ryder +2

We present preliminary results from a set of near-IR integral field spectroscopic observations of the central, star-burst, regions of the barred spiral galaxy M83, obtained with CI…

GRB 011121: A Massive Star Progenitor

P. A. Price, E. Berger, D. E. Reichart +29

Of the cosmological gamma-ray bursts, GRB 011121 has the lowest redshift, z=0.36. More importantly, the multi-color excess in the afterglow detected in the Hubble Space Telescope (…
