Ground-based optical spectra and Hubble Space Telescope images of 10 core-collapse supernovae (CCSNe) obtained several years to decades after outburst are analyzed with the aim of understanding the general properties of their late-time emissions. New observations of SN 1957D, 1970G, 1980K, and 1993J are included as part of the study. Blueshifted line emissions in oxygen and/or hydrogen with conspicuous line substructure are a common and long-lasting phenomenon in the late-time spectra. Followed… Expand
Supernova 1998S at 14 years postmortem: continuing circumstellar interaction and dust formation
We report late-time spectroscopic observations of the Type IIn supernova (SN) 1998S, taken 14 years after explosion using the Large Binocular Telescope. The optical spectrum exhibits strong, broadExpand
Detection of Late-time Optical Emission from SN 1941C in NGC 4136
We report the detection of broad, high-velocity oxygen emission lines from the site of SN 1941C nearly eight decades after outburst, making it the oldest optically detected core-collapseExpand
The Transition of a Type IIL Supernova into a Supernova Remnant: Late-time Observations of SN 2013by
We present early-time Swift and Chandra X-ray data along with late-time optical and near-infrared observations of SN 2013by, a Type IIL supernova (SN) that occurred in the nearby spiral galaxy ESOExpand
Evidence for a Pulsar Wind Nebula in the Type Ib Peculiar Supernova SN 2012au

LATE-TIME CIRCUMSTELLAR INTERACTION IN A SPITZER SELECTED SAMPLE OF TYPE IIn SUPERNOVAE
Type IIn supernovae (SNe IIn) are a rare (<10%) subclass of core-collapse SNe that exhibit relatively narrow emission lines from a dense, pre-existing circumstellar medium (CSM). In 2009, a warmExpand
Moderately luminous Type II supernovae
Context. Core-collapse Supernovae (CC-SNe) descend from progenitors more massive than about 8 M⊙. Because of the young age of the progenitors, the ejecta may eventually interact with theExpand
A MID-LIFE CRISIS? SUDDEN CHANGES IN RADIO AND X-RAY EMISSION FROM SUPERNOVA 1970G
Supernovae (SNe) provide a backdrop from which we can probe the end state of stellar evolution in the final years before the progenitor star explodes. As the shock from the SN expands, the timespanExpand
After the Fall: Late-Time Spectroscopy of Type IIP Supernovae
Herein we analyse late-time (post-plateau; 103 < t < 1229 d) optical spectra of low-redshift (z < 0.016), hydrogen-rich Type IIP supernovae (SNe IIP). Our newly constructed sample contains 91 nebularExpand
A decade of ejecta dust formation in the Type IIn SN 2005ip
In order to understand the contribution of core-collapse supernovae to the dust budget of the early universe, it is important to understand not only the mass of dust that can form in core-collapseExpand
Modelling supernova line profile asymmetries to determine ejecta dust masses: SN 1987A from days 714 to 3604
The late time optical and near-IR line profiles of many core-collapse supernovae exhibit a red-blue asymmetry as a result of greater extinction by internal dust of radiation emitted from the recedingExpand
