Multi-Epoch X-Ray Detection of SLSN-I 2018bsz: Constraints on the Powering Mechanism and Ejecta Structure
Julia Ahlvind, Josefin Larsson, Dennis Alp +1
SN 2018bsz is the closest known stripped superluminous supernova (SLSN-I) to date, making it an ideal laboratory for investigating the physical mechanisms powering this class of ex…
X-Ray Observations of Old Nearby Supernovae: Constraints on Compact Object Populations and Late Interaction
Julia Ahlvind, Josefin Larsson, Dennis Alp
The properties of the population of compact objects created in core-collapse supernovae (SNe) are uncertain. X-ray observations years to decades after the explosions offer a way to…
Luminosity function and event rate density of XMM-Newton-selected supernova shock-breakout candidates
Hui Sun, He-Yang Liu, Hai-Wu Pan +6
A dozen X-ray supernova shock breakout (SN SBO) candidates were reported recently based on XMM-Newton archival data, which increased the X-ray selected SN SBO sample by an order of…
Thermal Emission and Radioactive Lines, but No Pulsar, in the Broadband X-Ray Spectrum of Supernova 1987A
Dennis Alp, Josefin Larsson, Claes Fransson
Supernova 1987A offers a unique opportunity to study an evolving supernova in unprecedented detail over several decades. The X-ray emission is dominated by interactions between the…
Blasts from the Past: Supernova Shock Breakouts among X-Ray Transients in the XMM-Newton Archive
Dennis Alp, Josefin Larsson
The first electromagnetic signal from a supernova (SN) is released when the shock crosses the progenitor surface. This shock breakout (SBO) emission provides constraints on progeni…
The matter beyond the ring: the recent evolution of SN 1987A observed by the Hubble Space Telescope
J. Larsson, C. Fransson, D. Alp +14
The nearby SN 1987A offers a spatially resolved view of the evolution of a young supernova remnant. Here we precent recent Hubble Space Telescope imaging observations of SN 1987A,…
