Cosmology Constraints from Type Ia Supernova Simulations of the Nancy Grace Roman Space Telescope Strategy Recommended by the High-Latitude Time Domain Survey Definition Committee

The Astrophysical Journal
Within the next few years, the upcoming Nancy Grace Roman Space Telescope will be gathering data for the High-Latitude Time Domain Survey (HLTDS) that will be used to significantly improve the Type Ia supernova measurement of the dark energy equation of ...

The Remarkable Late-time Flux Excess in Hubble Space Telescope Observations of the Type Iax Supernova 2012Z

The Astrophysical Journal
Type Iax supernovae (SNe Iax) are thermonuclear explosions of white dwarfs (WDs), peculiar and underluminous compared to the normal Type Ia supernovae (SNe).

JWST and Ground-based Observations of the Type Iax Supernovae SN 2024pxl and SN 2024vjm: Evidence for Weak Deflagration Explosions

The Astrophysical Journal Letters
We present panchromatic optical + near-infrared (NIR) + mid-infrared (MIR) observations of the intermediate-luminosity Type Iax supernova (SN Iax) 2024pxl and the extremely low-luminosity SN Iax 2024vjm.

Detection of [C i] Emission in Nebular Spectra of a Peculiar Type Ia Supernova 2022pul

The Astrophysical Journal Letters
SN 2022pul gains special attention due to its possible origin as a super-Chandrasekhar-mass white dwarf (WD) explosion (also called a 03fg-like Type Ia supernova), which shows prominent [O i ], [Ne i ], and [Ca ii ] lines in its late-time spectra taken ...
