A 50 s quasi-periodic oscillation in the early X-ray afterglow of GRB 220711B
H. Gao, W. -H. Lei, S. Xiao +19
It is generally believed that long duration gamma-ray bursts (GRBs) originate from the core collapse of rapidly spinning massive stars and at least some of them are powered by hype…
A Hubble Space Telescope Search for r-Process Nucleosynthesis in Gamma-ray Burst Supernovae
J. C. Rastinejad, W. Fong, A. J. Levan +23
The existence of a secondary (in addition to compact object mergers) source of heavy element (-process) nucleosynthesis, the core-collapse of rapidly-rotating and highly-magneti…
JWST detection of heavy neutron capture elements in a compact object merger
A. Levan, B. P. Gompertz, O. S. Salafia +80
The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the progenitors of gamma-ray burs…
Mapping Obscured Star Formation in the Host Galaxy of FRB 20201124A
Yuxin Dong, Tarraneh Eftekhari, Wen-fai Fong +23
We present high-resolution 1.5 6 GHz Karl G. Jansky Very Large Array (VLA) and Hubble Space Telescope (HST) optical and infrared observations of the extremely active repeating…
An X-ray Census of Fast Radio Burst Host Galaxies: Constraints on AGN and X-ray Counterparts
T. Eftekhari, W. Fong, A. C. Gordon +16
We present the first X-ray census of fast radio burst (FRB) host galaxies to conduct the deepest search for AGN and X-ray counterparts to date. Our sample includes seven well-local…
Characterizing the FRB host galaxy population and its connection to transients in the local and extragalactic Universe
Shivani Bhandari, Kasper E. Heintz, Kshitij Aggarwal +23
We present the localization and host galaxies of one repeating and two apparently non-repeating Fast Radio Bursts. FRB20180301A was detected and localized with the Karl G. Jansky V…
Deep optical observations contemporaneous with emission from the periodic FRB 180916.J0158+65
Charles D. Kilpatrick, Joseph N. Burchett, David O. Jones +6
We present deep Apache Point Observatory optical observations within seconds of the outburst of the periodic fast radio burst (FRB) 180916.J0158+65 obtained on 3 September 2020. FR…
Confronting the Magnetar Interpretation of Fast Radio Bursts Through Their Host Galaxy Demographics
Mohammadtaher Safarzadeh, J. Xavier Prochaska, Kasper E. Heintz +1
We explore the prompt magnetar progenitor scenario in the context of fast radio burst (FRB) host galaxies demographics and offset distributions. Magnetars are neutron stars with st…
The properties of GRB 120923A at a spectroscopic redshift of z=7.8
N. R. Tanvir, T. Laskar, A. J. Levan +37
Gamma-ray bursts (GRBs) are powerful probes of early stars and galaxies, during and potentially even before the era of reionization. Although the number of GRBs identified at z>6 r…
