Interacting stellar winds feeding Sgr A*: from the system of mass-losing stars to the binary IRS 16SW
Diego Calderón, Jorge Cuadra, Christopher M. P. Russell +3
The discovery of cold structures around Sgr A* has challenged our understanding of the gas dynamics and thermodynamic state of the plasma in its vicinity. This work aims to constra…
General relativistic hydrodynamics of stellar tidal disruptions in Kerr spacetime: methods, validation, and first applications
Diego Calderón, Stephan Rosswog
The disruption of a star by the tidal field of a super-massive black hole may provide insights into dormant and otherwise hard-to-study galactic nuclei. State-of-the-art numerical…
Rapid and robust simulation-based inference for kilonovae
Stephanie M. Brown, Mattia Bulla, Hiranya V. Peiris +6
With the next generation of both electromagnetic and gravitational wave observatories beginning to come online, rapid analysis methods for kilonova data are becoming increasingly i…
Quantifying the impact of relativistic precession on tidal disruption event light curves
Diego Calderón, OndÅej 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…
Robustness of Magnetic Field Amplification in Neutron Star Mergers
Ricard Aguilera-Miret, Jan-Erik Christian, Stephan Rosswog +1
The dynamics of a binary neutron stars merger is governed by physics under the most extreme conditions, including strong spacetime curvature, ultra-high matter densities, luminous…
Prompt Periodicity in the GRB 211211A Precursor: Black-hole or magnetar engine?
Gavin P. Lamb, Thomas Baxter, Conor M. B. Omand +18
The merger origin long GRB 211211A was a class (re-)defining event. A precursor was identified with a s separation from the main burst, as well as a claimed candidate quas…
