Ultraviolet to Infrared Spectroscopy of the Type Ibn SN 2023tsz Suggests a Lower-mass Progenitor
Sergiy S. Vasylyev, Griffin Hosseinzadeh, Luc Dessart +42
Type Ibn supernovae are stripped-envelope explosions whose spectra indicate interaction with dense, helium-rich and hydrogen-poor circumstellar material (CSM), making them importan…
JWST observations of SN 2024abup: First Detection of CO in a broad-lined Type Ic Supernova and Constraints on r-process Nucleosynthesis
Manisha Shrestha, Lindsey A. Kwok, David J. Sand +42
SN 2024abup is a nearby broad-lined Type Ic supernova (SN Ic-bl) in NGC 0681 at a distance of 23.3 \pm 1.6 Mpc. As energetic explosions of massive stars, SNe Ic-bl are considered a…
SN 2023zcu: A Type IIP SN with Early Flash Features
Monalisa Dubey, Kuntal Misra, Géza Csörnyei +51
We present a detailed photometric and spectroscopic analysis of the Type IIP supernova SN~2023zcu, which exploded in the galaxy NGC~2139 (redshift = 0.006). SN~2023zcu exhibits…
SN 2019vxm: A Shocking Coincidence between Fermi and TESS
Zachary G. Lane, Ryan Ridden-Harper, Sofia Rest +37
Shock breakout and, in some cases, jet-driven high-energy emission are increasingly recognized as key signatures of the earliest phases of core-collapse supernovae, especially in T…
Extended Shock Breakout and Early Circumstellar Interaction in SN 2024ggi
Manisha Shrestha, K. Azalee Bostroem, David J. Sand +40
We present high-cadence photometric and spectroscopic observations of supernova (SN) 2024ggi, a Type II SN with flash spectroscopy features which exploded in the nearby galaxy NGC…
The carbon-rich type Ic supernova 2016adj in the iconic dust lane of Centaurus A: signatures of interaction with circumstellar hydrogen?
Maximilian D. Stritzinger, Eddie Baron, Francesco Taddia +24
We present a comprehensive data set of supernova (SN) 2016adj located within the central dust lane of Centaurus A. SN 2016adj is significantly reddened and after correcting the pea…
SN 2015bf: a fast declining type II supernova with flash-ionised signatures
Han Lin, Xiaofeng Wang, Jujia Zhang +19
We present optical and ultraviolet photometry, as well as optical spectra, for the type II supernova (SN) 2015bf. Our observations cover the phases from to d af…
Rigid colourings of hypergraphs and contiguity
Peter Ayre, Catherine Greenhill
We consider the problem of -colouring a -uniform random hypergraph, where , and determine the rigidity threshold. For edge densities above the rigidity threshold,…
Type Ia Supernova Carbon Footprints
R. C. Thomas, G. Aldering, P. Antilogus +32
We present convincing evidence of unburned carbon at photospheric velocities in new observations of 5 Type Ia supernovae (SNe Ia) obtained by the Nearby Supernova Factory. These SN…
