Inferring the role of binary neutron star mergers in r-process nucleosynthesis with multi-messenger observations using Cosmic Explorer and Einstein Telescope
Aman Agarwal, Suvodip Mukherjee, Daniel M. Siegel
Identifying the cosmic origin of rapid neutron-capture (r-process) elements remains an open problem. Binary neutron-star (BNS) mergers and rare classes of core-collapse supernovae…

Blinded Mock Data Challenge for Gravitational-Wave Cosmology-I: Assessing the Robustness of Methods Using Binary Black Holes Mass Spectrum
Aman Agarwal, Ulyana Dupletsa, Konstantin Leyde +18
Gravitational Wave (GW) sources are standard sirens that provide an independent way to map the cosmic expansion history by combining with an independent redshift measurement either…

Ignition of weak interactions and r-process outflows in super-collapsar accretion disks
Aman Agarwal, Daniel M. Siegel, Brian D. Metzger +1
The collapse of rotating massive (~) stars resulting in hyperaccreting black holes (BHs; "collapsars") is a leading model for the central engines of long-duration gamma…
