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…

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…

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…

"Super-Kilonovae" from Massive Collapsars as Signatures of Black-Hole Birth in the Pair-instability Mass Gap

Daniel M. Siegel, Aman Agarwal, Jennifer Barnes +3

The core collapse of rapidly rotating massive ~10 Msun stars ("collapsars"), and resulting formation of hyper-accreting black holes, are a leading model for the central engines of…
