The ALMA carbon monoxide supernova (ACOS) survey II. Turbulent giant molecular clouds at the positions of core-collapse supernovae
M. Solar, M. J. Michałowski, J. Nadolny +11
Context. Study of cold molecular hydrogen gas (hereafter molecular gas) provides crucial insights into its interplay with star-forming regions. However, the connection between mole…
The Search for Stable Nickel: Investigating the Origins of Type Ia Supernovae with Late-time NIR Spectroscopy from the Carnegie Supernova Project-II
Sahana Kumar, Eric Y. Hsiao, Christopher Ashall +20
Producing stable Ni in Type Ia supernovae (SNe Ia) requires sufficiently high density conditions that are not predicted for all origin scenarios, so examining the distributi…
Characterizing the Roman Grism Redshift Efficiency of Type Ia Supernova Host Galaxies for the High-Latitude Time-Domain Survey
R. C. Chen, Z. Guo, D. Scolnic +8
The High-Latitude Time-Domain Survey (HLTDS) for the Nancy Grace Roman Space Telescope (Roman) will discover thousands of high redshift Type Ia supernovae (SNeIa) to make generatio…
The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40
SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…
