Outflows in steep density gradients: diversity of behavior and implications for tidal disruption events and luminous fast blue optical transients
Benjamin Amend, Michael Camilo, Eric R. Coughlin +2
Powerful explosions may undergo sustained energy injection as a central engine launches a wind into the surrounding gas, generating a forward and a reverse shock separated by a con…
The Role of Stellar Spin in Repeating Partial Tidal Disruption Events
Ananya Bandopadhyay, Benjamin Amend, Eric R. Coughlin +3
The repeated tidal stripping of a star by a supermassive black hole, known as a repeating partial tidal disruption event (rpTDE), can give rise to a transient that rebrightens mont…
Systematic Error in Approximate Models of the GRB Early Afterglow
Benjamin Amend, Eric R. Coughlin, Jonathan Zrake
Gamma-ray burst (GRB) afterglows are thought to arise when relativistic ejecta launched by a compact central engine drive a blast wave into the surrounding circumburst medium, prod…
On the Origin of Mass Ejection in Failed Supernovae
Daniel A. Paradiso, Sarah Vallejo, Eric R. Coughlin
Some high-mass stars likely end their lives in underluminous implosions that leave behind a black hole, known as failed supernovae (FSNe). However, neutrinos radiated during proto-…
Repeating Nuclear Transients from Repeating Partial Tidal Disruption Events
Ananya Bandopadhyay, Eric R. Coughlin, Julia Fancher +2
Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A s…
AT2024lhc and AT2024kmq in the landscape of featureless tidal disruption events
Yuhan Yao, Ryan Chornock, Andrew Mummery +39
We study AT2024kmq and AT2024lhc, two tidal disruption events (TDEs) with blue featureless spectra associated with high-mass black holes (). Both even…
