Traces of Helium Detected in Type Ic Supernova 2014L
Jing Lu, Wolfgang E. Kerzendorf, John T. O'Brien +6
The absence of helium features in optical spectra is one of the classification criteria for Type Ic supernovae (SNe Ic). However, it is highly debated whether helium is truly absen…
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…
1991T-Like Type Ia Supernovae as an Extension of the Normal Population
John T. O'Brien, Wolfgang E. Kerzendorf, Andrew Fullard +7
Type Ia supernovae remain poorly understood despite decades of investigation. Massive computationally intensive hydrodynamic simulations have been developed and run to model an eve…
Over 500 Days in the Life of the Photosphere of the Type Iax Supernova SN 2014dt
Yssavo Camacho-Neves, Saurabh W. Jha, Barnabas Barna +20
Type Iax supernovae (SN Iax) are the largest known class of peculiar white dwarf supernovae, distinct from normal Type Ia supernovae (SN Ia). The unique properties of SN Iax, espec…
A JWST Near- and Mid-Infrared Nebular Spectrum of the Type Ia Supernova 2021aefx
Lindsey A. Kwok, Saurabh W. Jha, Tea Temim +55
We present JWST near- and mid-infrared spectroscopic observations of the nearby normal Type Ia supernova SN 2021aefx in the nebular phase at days past maximum light. Our Nea…
On the fate of the secondary white dwarf in double-degenerate double-detonation Type Ia supernovae
R. Pakmor, F. P. Callan, C. E. Collins +12
The progenitor systems and explosion mechanism of Type Ia supernovae are still unknown. Currently favoured progenitors include double-degenerate systems consisting of two carbon-ox…
New mass estimates for massive binary systems: a probabilistic approach using polarimetric radiative transfer
Andrew G. Fullard, John T. O'Brien, Wolfgang E. Kerzendorf +4
Understanding the evolution of massive binary stars requires accurate estimates of their masses. This understanding is critically important because massive star evolution can poten…
Probabilistic Reconstruction of Type Ia Supernova SN 2002bo
John T. O'Brien, Wolfgang E. Kerzendorf, Andrew Fullard +8
Manual fits to spectral times series of Type Ia supernovae have provided a method of reconstructing the explosion from a parametric model but due to lack of information about model…
Properties of a Previously Unidentified Instrumental Signature in that was Confused for AGN Variability
Jackeline Moreno, Rachel Buttry, John O'Brien +3
The satellite potentially provides the highest precision photometry of active galactic nuclei (AGN) available to investigate short-timescale optical variability.…
Transient radio bursts from rotating neutron stars
M. A. McLaughlin, A. G. Lyne, D. R. Lorimer +11
The `radio sky' is relatively unexplored for transient signals, although the potential of radio-transient searches is high, as demonstrated recently by the discovery of a previousl…
The Shocking Properties of Supersonic Flows: Dependence of the Thermal Overstability on M, alpha, and T_c/T_0
J. M. Pittard, M. S. Dobson, R. H. Durisen +3
We investigate the Mach number dependence of the radiative overstability of shocks. We find that the stability of radiative shocks increases with decreasing Mach number, with the r…
Complete measurement of three-body photodisintegration of 3He for photon energies between 0.35 and 1.55 GeV
CLAS Collaboration, S. Niccolai, G. Audit +3
The three-body photodisintegration of 3He has been measured with the CLAS detector at Jefferson Lab, using tagged photons of energies between 0.35 GeV and 1.55 GeV. The large accep…
Electroproduction of the hyperon
S. P. Barrow
The reaction with was studied at electron beam energies of 4.05, 4.25, and 4.46 GeV, using the CLAS detector at the Thomas Jefferson Natio…
The e p -> e' p eta reaction at and above the S11(1535) baryon resonance
The CLAS Collaboration, R. Thompson
New cross sections for the reaction e p -> ep eta are reported for total center of mass energy W = 1.5--1.86 GeV and invariant momentum transfer Q^2 = 0.25--1.5 GeV^2. This large k…
