A Novel Parameterization for Rapid Cooling in Supernova Remnants, with applications to the Pa 30 nebula
Miranda Pikus, Paul Duffell, Soham Mandal +1
We systematically study how cooling creates structural changes in supernova remnants as they evolve. Inspired by the peculiar morphology of the Pa 30 nebula, we adopt a framework i…
Optimizing Kilonova Searches: A Case Study of the Type IIb SN 2025ulz in the Localization Volume of the Low-Significance Gravitational Wave Event S250818k
Noah Franz, Bhagya Subrayan, Charles D. Kilpatrick +54
Kilonovae, the ultraviolet/optical/infrared counterparts to binary neutron star mergers, are an exceptionally rare class of transients. Optical follow-up campaigns are plagued by c…
Two-Dimensional Radiation-Hydrodynamic Simulations of Luminous Red Novae
Anthony Kirilov, Diego Calderón, Ondřej Pejcha +1
Luminous Red Novae (LRNe) are transients associated with mass ejection during stellar mergers and common envelope evolution (CEE). LRNe have the potential to illuminate the poorly…
A Late-time Radio Search for Highly Off-axis Jets from PTF Broad-lined Ic Supernovae in GRB-like Host Galaxy Environments
Genevieve Schroeder, Anna Y. Q. Ho, Ranadeep G. Dastidar +3
Hydrogen/Helium-poor stripped-envelope core-collapse supernovae with broad lines (SNe Ic-bl) almost always accompany the nearby () jetted relativistic explosions known as…
A Novel Relationship Between Gamma Ray Burst Duration And Photospheric Radius
Ranadeep Ghosh Dastidar, Paul Duffell
Long Gamma Ray Bursts (lGRBs) are associated with jets in Type Ic broadline supernovae. The Collapsar model provides a theoretical framework for the jet formation from the core col…
EP250108a/SN 2025kg: A Jet-Driven Stellar Explosion Interacting With Circumstellar Material
Gokul P. Srinivasaragavan, Hamid Hamidani, Genevieve Schroeder +28
We present optical, radio, and X-ray observations of EP250108a/SN 2025kg, a broad-line Type Ic supernova (SN Ic-BL) accompanying an Einstein Probe (EP) fast X-ray transient (FXT) a…
The Non-Uniform Expansion of the Crab Nebula
T. Martin, D. Milisavljevic, T. Temim +4
We present extensive proper motion measurements of the Crab Nebula made from Canada-France-Hawaii Telescope MegaPrime/MegaCam images taken in 2007, 2016, and 2019. A total of 19974…
Quantifying Advantages of a Moving Mesh in Nuclear Hydrodynamics
Dillon Hasenour, Paul Duffell
Many astrophysical explosions, such as type Ia supernovae, classical novae, and X-ray bursts, are dominated by thermonuclear runaway. To model these processes accurately, one must…
