Large Cold Dust Reservoir Revealed in Transitional SN Ib 2014C by James Webb Space Telescope Mid-Infrared Spectroscopy
Samaporn Tinyanont, Ori D. Fox, Melissa Shahbandeh +32
Supernova (SN) 2014C is a rare transitional event that exploded as a hydrogen-poor, helium-rich Type Ib SN and subsequently interacted with a hydrogen-rich circumstellar medium (CS…
The James Webb Space Telescope Mission
Jonathan P. Gardner, John C. Mather, Randy Abbott +1004
Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized…
JWST and Ground-based Observations of the Type Iax Supernovae SN 2024pxl and SN 2024vjm: Evidence for Weak Deflagration Explosions
Lindsey A. Kwok, Mridweeka Singh, Saurabh W. Jha +89
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…
High-Energy Emission from the Composite Supernova Remnant MSH 15-56
Tea Temim, Patrick Slane, Daniel Castro +3
MSH 15-56 (G326.3-1.8) is a composite supernova remnant (SNR) that consists of an SNR shell and a displaced pulsar wind nebula (PWN) in the radio. We present XMM-Newton and Chandra…
Properties and Spatial Distribution of Dust Emission in the Crab Nebula
Tea Temim, George Sonneborn, Eli Dwek +4
Recent infrared (IR) observations of freshly-formed dust in supernova remnants (SNRs) have yielded significantly lower dust masses than predicted by theoretical models and measured…
Interpreting Crab Nebula synchrotron spectrum: two acceleration mechanisms
Maxim Lyutikov, Tea Temim, Sergey Komissarov +3
We outline a model of the Crab Pulsar Wind Nebula with two different populations of synchrotron emitting particles, arising from two different acceleration mechanisms: (i) Componen…
