Double Detonations on a Moving Mesh with : Characterizing Early Reddening in SNe Ia
Dillon Hasenour, Paul Duffell, Abigail Polin
Type Ia supernovae are useful as cosmological distance indicators and are significant sources of chemical enrichment in galaxies, but much about their origins remains uncertain. Th…
AT2018hyz: Predictions for a Sky Projection from a Delayed Off-Axis Jet
Ranadeep Ghosh Dastidar, Paul C Duffell
Initially discovered optically, Tidal Disruption Event (TDE) AT2018hyz was first detected in radio 972 days later. The continued monitoring of the event revealed a late-time (1370-…
Instability and Angular Momentum Transfer in Thick Circumbinary Disks
Allen R. Murray, Paul C. Duffell
Utilizing the DISCO code we solve the 2D hydrodynamic equations for an equal mass circular restricted binary with an isothermal circumbinary disk (CBD). This work explores the ecce…
High-Resolution Numerical Calculations of GRB Afterglow Plateaus arising from Stratified Ejecta
Paul C. Duffell, Ranadeep Ghosh Dastidar
Since the discovery of plateaus in GRB afterglows by Swift, they have been modeled predominantly by late-time energy injection. However, many studies have suggested that the platea…
Exploring the effect of mixing in Low-Luminosity Type IIp Supernovae by modeling SN 2024abfl
Akshith Karri, Abigail Polin, Paul Duffell
Low-luminosity Type IIp supernovae (LLSNe) are SN IIps with peak magnitudes > -15.5 and plateau magnitudes between -13.5 and -15.5 in the V band. SN 2024abfl is an LLSN with a uniq…
Quantifying the impact of relativistic precession on tidal disruption event light curves
Diego Calderón, Ondřej Pejcha, Brian D. Metzger +2
The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impa…
