Ground-based and JWST Observations of SN 2022pul: I. Unusual Signatures of Carbon, Oxygen, and Circumstellar Interaction in a Peculiar Type Ia Supernova

Matthew R. Siebert, Lindsey A. Kwok, Joel Johansson +79

Nebular-phase observations of peculiar Type Ia supernovae (SNe Ia) provide important constraints on progenitor scenarios and explosion dynamics for both these rare SNe and the more…

Ground-based and JWST Observations of SN 2022pul: II. Evidence from Nebular Spectroscopy for a Violent Merger in a Peculiar Type-Ia Supernova

Lindsey A. Kwok, Matthew R. Siebert, Joel Johansson +78

We present an analysis of ground-based and JWST observations of SN~2022pul, a peculiar "03fg-like" (or "super-Chandrasekhar") Type Ia supernova (SN Ia), in the nebular phase at 338…

Examining Neutrino-Matter Interactions in the Cassiopeia A Supernova

Toshiki Sato, Takashi Yoshida, Hideyuki Umeda +4

Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confi…

The Atacama Cosmology Telescope: High-resolution component-separated maps across one-third of the sky

William R. Coulton, Mathew S. Madhavacheril, Adriaan J. Duivenvoorden +151

Observations of the millimeter sky contain valuable information on a number of signals, including the blackbody cosmic microwave background (CMB), Galactic emissions, and the Compt…

No Surviving SN Ia Companion In SNR 0509-67.5: Stellar Population Characterization and Comparison To Models

Joshua V. Shields, Prasiddha Arunachalam, Wolfgang Kerzendorf +4

The community agrees that Type Ia supernovae arise from Carbon/Oxygen white dwarfs undergoing thermonuclear runaway. However, the full progenitor system and the process that prompt…

ACT-DR5 Sunyaev-Zel'dovich Clusters: weak lensing mass calibration with KiDS

Naomi Clare Robertson, Cristóbal Sifón, Marika Asgari +24

We present weak gravitational lensing measurements of a sample of 157 clusters within the Kilo Degree Survey (KiDS), detected with a thermal Sunyaev-Zel'dovich (SZ) signal by…
