JWST spectroscopy of SN 2010da/NGC 300 ULX-1: a surviving star hidden by dust
Emma R. Beasor, Ryan Lau, Nathan Smith +3
We present new James Webb Space Telescope () NIRSpec and MIRI integral-field spectroscopy of the remarkable system SN~2010da / NGC~300 ULX-1, the only known ultraluminous X-r…
JWST Reveals Large Reservoirs of Dust and Ongoing Circumstellar Interaction in SN Ibn/Icn 2023xgo over a Year Post-Explosion
Kyle W. Davis, Kirsty Taggart, Samaporn Tinyanont +23
We present infrared (IR) photometric and spectroscopic observations of SN 2023xgo, a recent and nearby Type Ibn/Icn supernova (SN Ibn/Icn) which shows shock interaction with a He/C…
An infrared echo from a circumstellar disk in the hydrogen- and helium-poor SN 2024aecx
Samaporn Tinyanont, Kittipong Wangnok, Jennifer E. Andrews +34
We present near-infrared (NIR) spectroscopy of the hydrogen- and helium-poor (Type Ic) supernova (SN) 2024aecx, which displays a strong NIR excess emerging 32 days post peak. SN 20…
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…
JWST/MIRI Observations of Newly Formed Dust in the Cold, Dense Shell of the Type IIn SN 2005ip
Melissa Shahbandeh, Ori D. Fox, Tea Temim +42
Dust from core-collapse supernovae (CCSNe), specifically Type IIP SNe, has been suggested to be a significant source of the dust observed in high-redshift galaxies. CCSNe eject lar…
Disappearance of a massive star in the Andromeda Galaxy due to formation of a black hole
Kishalay De, Morgan MacLeod, Jacob E. Jencson +11
When a massive star reaches the end of its lifetime, its core collapses and releases neutrinos that drive a shock into the outer layers (stellar envelope). A sufficiently strong sh…
WTP19aalnxx: Discovery of a bright mid-infrared transient in the emerging class of low luminosity supernovae revealed by delayed circumstellar interaction
Charlotte Myers, Kishalay De, Lin Yan +11
While core-collapse supernovae (SNe) often show early and consistent signs of circumstellar (CSM) interaction, some exhibit delayed signatures due to interaction with distant mater…
Emission lines due to ionizing radiation from a compact object in the remnant of Supernova 1987A
C. Fransson, M. J. Barlow, P. J. Kavanagh +31
The nearby Supernova 1987A was accompanied by a burst of neutrino emission, which indicates that a compact object (a neutron star or black hole) was formed in the explosion. There…
Ejecta, Rings, and Dust in SN 1987A with JWST MIRI/MRS
O. C. Jones, P. J. Kavanagh, M. J. Barlow +31
Supernova (SN) 1987A is the nearest supernova in 400 years. Using the {\em JWST} MIRI Medium Resolution Spectrograph, we spatially resolved the ejecta, equatorial ring (ER) a…
JWST NIRSpec observations of Supernova 1987A -- from the inner ejecta to the reverse shock
J. Larsson, C. Fransson, B. Sargent +23
We present initial results from JWST NIRSpec integral field unit observations of the nearby Supernova (SN) 1987A. The observations provide the first spatially-resolved spectroscopy…
Discovery of a red supergiant donor star in SN2010da/NGC 300 ULX-1
M. Heida, R. M. Lau, B. Davies +7
SN2010da/NGC 300 ULX-1 was first detected as a supernova impostor in May 2010 and was recently discovered to be a pulsating ultraluminous X-ray source. In this letter, we present V…
