Evidence for Cocoon Emission from the Early Light Curve of SSS17a
Anthony L. Piro, Juna A. Kollmeier
Swope Supernova Survey 2017a (SSS17a) was discovered as the first optical counterpart to the gravitational wave event GW170817. Although its light curve on the timescale of weeks r…
Measuring the Progenitor Masses and Dense Circumstellar Material of Type II Supernovae
Viktoriya Morozova, Anthony L. Piro, Stefano Valenti
Recent modeling of hydrogen-rich Type II supernova (SN II) light curves suggests the presence of dense circumstellar material (CSM) surrounding the exploding progenitor stars. This…
The Fate of Neutron Star Binary Mergers
Anthony L. Piro, Bruno Giacomazzo, Rosalba Perna
Following merger, a neutron star (NS) binary can produce roughly one of three different outcomes: (1) a stable NS, (2) a black hole (BH), or (3) a supra-massive, rotationally-suppo…
What if the fast radio bursts 110220 and 140514 are from the same source?
Anthony L. Piro, Sarah Burke-Spolaor
The fast radio bursts (FRBs) 110220 and 140514 were detected at telescope pointing locations within 9 arcmin of each other over three years apart, both within the same 14.4 arcmin…
Numerically Modeling the First Peak of the Type IIb SN 2016gkg
Anthony L. Piro, Marc Muhleisen, Iair Arcavi +3
Many Type IIb supernovae (SNe) show a prominent additional early peak in their light curves, which is generally thought to be due to the shock cooling of extended hydrogen-rich mat…
Observational evidence for high neutronization in supernova remnants: implications for Type Ia supernova progenitors
Héctor Martínez-Rodríguez, Carles Badenes, Hiroya Yamaguchi +8
The physical process whereby a carbon--oxygen white dwarf explodes as a Type Ia supernova (SN Ia) remains highly uncertain. The degree of neutronization in SN Ia ejecta holds clues…
