JWST NIRCam Observations of SN 1987A: Spitzer Comparison and Spectral Decomposition
Richard G. Arendt, Martha L. Boyer, Eli Dwek +24
JWST NIRCam observations at 1.5-4.5 m have provided broad and narrow band imaging of the evolving remnant of SN 1987A with unparalleled sensitivity and spatial resolution. Compa…
Lightcurve and spectral modelling of the Type IIb SN 2020acat. Evidence for a strong Ni bubble effect on the diffusion time
Mattias Ergon, Peter Lundqvist, Claes Fransson +10
We use the light curve and spectral synthesis code JEKYLL to calculate a set of macroscopically mixed Type IIb supernova (SN) models, which are compared to both previously publishe…
Sub-arcsecond resolution imaging of M 51 with the International LOFAR Telescope
Deepika Venkattu, Peter Lundqvist, Miguel Pérez-Torres +5
We present an International LOFAR Telescope sub-arcsecond resolution image of the nearby galaxy M 51 with a beam size of 0.436" x 0.366" and rms of 46 Jy. We compare this image…
The Early Light Curve of SN 2023bee: Constraining Type Ia Supernova Progenitors the Apian Way
Griffin Hosseinzadeh, David J. Sand, Sumit K. Sarbadhicary +39
We present very early photometric and spectroscopic observations of the Type Ia supernova (SN Ia) 2023bee, starting about 8 hr after the explosion, which reveal a strong excess in…
SN2017egm: A Helium-rich Superluminous Supernova with Multiple Bumps in the Light Curves
Jiazheng Zhu, Ning Jiang, Subo Dong +28
When discovered, SN~2017egm was the closest (redshift ) hydrogen-poor superluminous supernova (SLSN-I) and a rare case that exploded in a massive and metal-rich galaxy. Thu…
Near-infrared evolution of the equatorial ring of SN 1987A
T. Kangas, A. Ahola, C. Fransson +4
We use adaptive-optics imaging and integral field spectroscopy from the Very Large Telescope, together with images from the \emph{Hubble Space Telescope}, to study the near-infrare…
