SN 2021csp -- the explosion of a stripped envelope star within a H and He-poor circumstellar medium
Morgan Fraser, Maximilian D. Stritzinger, Sean J. Brennan +48
We present observations of SN 2021csp, a unique supernova (SN) which displays evidence for interaction with H- and He- poor circumstellar material (CSM) at early times. Using high-…
Hunting for the nature of the enigmatic narrow-line Seyfert 1 galaxy PKS 2004-447
M. Berton, G. Peluso, P. Marziani +19
Narrow-line Seyfert 1 (NLS1) galaxies are a class of active galactic nuclei (AGN) that, in some cases, can harbor powerful relativistic jets. One of them, PKS 2004-447, shows gamma…
The episodic dust-making Wolf-Rayet star HD 38030 in the Large Magellanic Cloud
Peredur M. Williams, Nidia I. Morrell, Konstantina Boutsia +1
Mid-infrared photometry of the Wolf-Rayet star HD 38030 in the Large Magellanic Cloud from the NEOWISE-R mission show it to have undergone a dust-formation episode in 2018 and the…
BAT99-9 -- a WC4 Wolf-Rayet star with nitrogen emission: Evidence for binary evolution?
D. John Hillier, Erin Aadland, Philip Massey +1
An analysis of the Large Magellanic Cloud (LMC) WC4 star BAT99-9 (HD 32125, FD 4, Brey 7, WS 3) shows that the star still contains photospheric nitrogen. Three N emission features…
SN 2013ai: a link between hydrogen-rich and hydrogen-poor core-collapse supernovae
S. Davis, P. J. Pessi, M. Fraser +33
We present a study of optical and near-infrared (NIR) spectra along with the light curves of SN 2013ai. These data range from discovery until 380 days after explosion. SN 2013ai is…
