One year of broadband radio monitoring of the enigmatic transient GRB 250702B reveals the evolution of the relativistic jet
A. J. Goodwin, James C. A. Miller-Jones, Itai Sfaradi +19
We present an extensive radio monitoring campaign of the unique extragalactic transient GRB 250702B, with observations spanning 0.65-233 GHz from 6-356 d (observer frame) post-disc…
The Radio Properties of Extreme Coronal Line Emitters: Constraints on the Sub-parsec Environment
Noah Franz, Kate D. Alexander, Collin T. Christy +10
A tiny fraction () of galaxies display luminous, high-ionization metal emission lines, which may be persistent or variable. These extreme coronal lines (ECLs) are produced…
Beyond the Impulsive Approximation: The Dynamics and Radio Emission of Tidal Disruption Jets
Fabio De Colle, Enrico Ramirez-Ruiz
Radio emission from relativistic tidal disruption events (TDEs) is commonly interpreted using the Blandford--McKee solution for an impulsive relativistic blast wave. Unlike gamma-r…
Accretion-Driven Evolution of Compact-Object Populations in Gas-Rich Environments and the Origin of Massive Gravitational-Wave Sources
Mor Rozner, Alejandra Rosselli-Calderon, Enrico Ramirez-Ruiz
The origin of the most massive gravitational-wave sources remains elusive. We show that gas accretion can be understood as a transport process in mass space, causing compact object…
How Common Are Common Envelopes? Quantifying Their Role in Forming Gravitational-Wave Sources
Floor S. Broekgaarden, Ana Lam, Sasha Levina +14
A central goal of gravitational-wave astronomy is to use merging binary black hole (BBH), black hole-neutron star (BHNS), and binary neutron star (BNS) systems as fossils to recons…
What is the Strouhal number of turbulence driven by supernovae?
James R. Beattie, Isabelle Connor, Enrico Ramirez-Ruiz
The Strouhal number, , measures the temporal coherence of turbulent driving relative to the outer-scale eddy turnover time. In turbulence-box mod…
