Neutrinos from Type-II Supernovae

Abstract In our work we investigate the stellar surface fluxes of different neutrino flavors, both with and without matter effects, while aiming to consider the varying density of the progenitor star to reveal intriguing variations in their behavior. By examining both normal and inverted neutrino mass hierarchies in studies of neutrino fluxes,

Near-infrared Spectral Properties of Type Ib/Ic Supernova Progenitors and Implications for JWST and NGRST Observations

The Astrophysical Journal
While about 20 type II supernova (SN II) progenitors have been identified using optical data from the Hubble Space Telescope (HST), direct detection of type Ib/Ic supernova (SN Ib/Ic) progenitors remains challenging, due to their faint optical brightness

SN 2023ixf in Messier 101: The Twilight Years of the Progenitor as Seen by Pan-STARRS

The Astrophysical Journal
The nearby type II supernova, SN 2023ixf in M101 exhibits signatures of early time interaction with circumstellar material in the first week postexplosion. This material may be the consequence of prior mass loss suffered by the progenitor, which possibly

On the Pair-instability Supernova Origin of J1010+2358

The Astrophysical Journal Letters
The first (Population III) stars formed only out of H and He and were likely more massive than present-day stars. Massive Population III stars in the range 140–260 M _⊙ are predicted to end their lives as pair-instability supernovae (PISNe), enriching ...

JWST Observations of SN 2023ixf. I. Completing the Early Multiwavelength Picture with Plateau-phase Spectroscopy

The Astrophysical Journal
We present and analyze panchromatic (0.35–14 μ m) spectroscopy of the Type II supernova 2023ixf, including near- and mid-infrared spectra obtained 33.6 days after explosion during the plateau phase, with the James Webb Space Telescope (JWST). This is the
