Superluminous supernova SN 2018ibb: Circumstellar shell and spectral effects
Nikolai N. Chugai
I explore observational effects of the cirsumstellar gas around superluminous supernova SN~2018ibb. High velocity Fe II narrow absorptions are reproduced in the model of fragmented…
Study of X-ray emission from the S147 nebula by SRG/eROSITA: supernova-in-the-cavity scenario
Ildar I. Khabibullin, Eugene M. Churazov, Nikolai N. Chugai +11
The Simeis~147 nebula (S147), particularly well known for a spectacular net of -emitting filaments, is often considered one of the largest and oldest known supernova rem…
Study of X-ray emission from the S147 nebula with SRG/eROSITA: X-ray imaging, spectral characterization, and a multiwavelength picture
Miltiadis Michailidis, Gerd Pühlhofer, Werner Becker +11
Simeis 147 (S147, G180.0-01.7, "Spaghetti nebula") is a supernova remnant (SNR) extensively studied across the entire electromagnetic spectrum, from radio to giga-electronvolt -…
Discovery of a one-sided radio filament of PSR J0538+2817 in S147: escape of relativistic PWN leptons into surrounding supernova remnant?
Ildar Khabibullin, Eugene Churazov, Andrei Bykov +2
We report the discovery of a faint radio filament near PSR J0538+2817 in the NVSS, CGPS, and the Rapid ASKAP Continuum Survey data. This pulsar is plausibly associated with the sup…
Cosmic abundance of iron
Nikolai Chugai
I explore a possibility to estimate an upper limit of the current iron abundance of the barion matter. The upper limit is determined by the minimal iron abundance, at which the gam…
Supernova 2009ip outbursts in 2012: From scenario to model
Nikolai Chugai
Spherical and aspherical models are presented for two outbursts in 2012 of supernova 2009ip. Models are based on a scenario which suggests that the August 2012 outburst is caused b…
