Constraining hydrodynamic model of nearby type IIP SN 2023ixf
V. P. Utrobin, N. N. Chugai
Despite proximity of SN 2023ixf and a wealth of observational data, the released hydrodynamic models leave too broad range of the derived explosion energy and the ejected mass. We…

Southern eROSITA bubble as a forward shock and the low-metallicity CGM. South-east side story
E. Churazov, I. I. Khabibullin, A. M. Bykov +4
Unlike the complicated X-ray and radio structure observed in the North Polar Spur area, the South-Eastern part of the eROSITA bubbles can be reasonably well described as a propagat…

Type IIP SN 2024bch: Hydrodynamic model, shock breakout, and circumstellar interaction
V. P. Utrobin, N. N. Chugai
The well-observed type IIP SN 2024bch with the short plateau is shown to be an outcome of the red supergiant explosion with the presupernova mass of 14-15 Msun, the explosion energ…
