High angular resolution ALMA images of dust and molecules in the SN 1987A ejecta
Phil Cigan, Mikako Matsuura, Haley L. Gomez +23
We present high angular resolution (~80 mas) ALMA continuum images of the SN 1987A system, together with CO =2 1, =6 5, and SiO =5 $\!\…
Detection of Linear Polarization in the Radio Remnant of Supernova 1987A
Giovanna Zanardo, Lister Staveley-Smith, B. M. Gaensler +4
Supernova 1987A in the Large Magellanic Cloud has proven a unique laboratory to investigate particle acceleration in young supernova remnants. Here we report the first detection of…
Search for a Radio Pulsar in the Remnant of Supernova 1987A
S. -B. Zhang, S. Dai, G. Hobbs +5
We have observed the remnant of supernova SN~1987A (SNR~1987A), located in the Large Magellanic Cloud (LMC), to search for periodic and/or transient radio emission with the Parkes…
The 30-Year Search for the Compact Object in SN 1987A
Dennis Alp, Josefin Larsson, Claes Fransson +32
Despite more than 30 years of searches, the compact object in Supernova (SN) 1987A has not yet been detected. We present new limits on the compact object in SN 1987A using millimet…
The Radio Remnant of Supernova 1987A - A Broader View
G. Zanardo, L. Staveley-Smith, C. -Y. Ng +4
Supernova remnants (SNRs) are powerful particle accelerators. As a supernova (SN) blast wave propagates through the circumstellar medium (CSM), electrons and protons scatter across…
Spectral and morphological analysis of the remnant of Supernova 1987A with ALMA & ATCA
Giovanna Zanardo, Lister Staveley-Smith, Remy Indebetouw +18
We present a comprehensive spectral and morphological analysis of the remnant of Supernova (SN) 1987A with the Australia Telescope Compact Array (ATCA) and the Atacama Large Millim…
The radio remnant of Supernova 1987A at high frequencies and high resolution
G. Zanardo, L. Staveley-Smith, C. -Y. Ng +4
As the remnant of Supernova (SN) 1987A has been getting brighter over time, new observations at high frequencies have allowed imaging of the radio emission at unprecedented detail.…
Radio Observations of Supernova 1987A
L. Staveley-Smith, T. M. Potter, G. Zanardo +2
Supernovae and their remnants are believed to be prodigious sources of Galactic cosmic rays and interstellar dust. Understanding the mechanisms behind their surprisingly high produ…
Evolution of the Radio Remnant of Supernova 1987A: Morphological Changes from Day 7000
C. -Y. Ng, G. Zanardo, T. M. Potter +4
We present radio imaging observations of supernova remnant 1987A at 9 GHz, taken with the Australia Telescope Compact Array over 21 years from 1992 to 2013. By employing a Fourier…
High-resolution radio observations of SNR 1987A at high frequencies
Giovanna Zanardo, L. Staveley-Smith, C. -Y. Ng +4
We present new imaging observations of the remnant of Supernova (SN) 1987A at 44 GHz, performed in 2011 with the Australia Telescope Compact Array (ATCA). The $0\farcs35\times0\far…
The remnant of Supernova 1987A resolved at 3 mm wavelength
Masha Lakicevic, Giovanna Zanardo, Jacco Th. van Loon +4
The proximity of core-collapse Supernova 1987A (SN1987A) in the Large Magellanic Cloud (LMC) and its rapid evolution make it a unique case study of the development of a young super…
First VLBI Detection of the Radio Remnant of Supernova 1987A: Evidence for Small-scale Features
C. -Y. Ng, T. M. Potter, L. Staveley-Smith +5
We present a detailed analysis of the first very long baseline interferometry (VLBI) detection of the radio remnant of supernova 1987A. The VLBI data taken in 2007 and 2008 at 1.4…
Multi-frequency Radio Measurements of SN 1987A over 22 Years
G. Zanardo, L. Staveley-Smith, Lewis Ball +6
We present extensive observations of the radio emission from the remnant of SN 1987A made with the Australia Telescope Compact Array (ATCA), since the first detection of the remnan…
