The first CHIME/FRB fast radio burst catalog

…, TL Landecker, D Lang, C Leung, D Li… - The Astrophysical …, 2021 - iopscience.iop.org
We present a catalog of 536 fast radio bursts (FRBs) detected by the Canadian Hydrogen
Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project between 400 and 800 …

The host galaxy and persistent radio counterpart of FRB 20201124A

V Ravi, CJ Law, D Li, K Aggarwal… - Monthly Notices of …, 2022 - academic.oup.com
The physical properties of fast radio burst (FRB) host galaxies provide important clues
towards the nature of FRB sources. The 16 FRB hosts identified thus far span three orders of …

CHIME/FRB catalog 1 results: statistical cross-correlations with large-scale structure

M Rafiei-Ravandi, KM Smith, D Li… - The Astrophysical …, 2021 - iopscience.iop.org
The CHIME/FRB Project has recently released its first catalog of fast radio bursts (FRBs),
containing 492 unique sources. We present results from angular cross-correlations of CHIME/…

Pulsar emission amplified and resolved by plasma lensing in an eclipsing binary

R Main, IS Yang, V Chan, D Li, FX Lin, N Mahajan… - Nature, 2018 - nature.com
Radio pulsars scintillate because their emission travels through the ionized interstellar
medium along multiple paths, which interfere with each other. It has long been realized that, …

Dynamical Formation Channels for Fast Radio Bursts in Globular Clusters

K Kremer, AL Piro, D Li - The Astrophysical Journal Letters, 2021 - iopscience.iop.org
The repeating fast radio burst (FRB) localized to a globular cluster (GC) in M81 challenges
our understanding of FRB models. In this Letter, we explore dynamical formation scenarios …

A highly magnetized environment in a pulsar binary system

D Li, A Bilous, S Ransom, R Main, YP Yang - Nature, 2023 - nature.com
Spider pulsars are millisecond pulsars in short-period (≲12-h) orbits with low-mass (~0.01–0.4
M ⊙ ) companion stars. The pulsars ablate plasma from the companion star, causing time …

Polarization pipeline for fast radio bursts detected by CHIME/FRB

…, PJ Boyle, C Brar, T Cassanelli, D Li… - The Astrophysical …, 2021 - iopscience.iop.org
Polarimetric observations of fast radio bursts (FRBs) are a powerful resource for better
understanding these mysterious sources by directly probing the emission mechanism of the …

Prospects for Detecting Fast Radio Bursts in the Globular Clusters of Nearby Galaxies

K Kremer, D Li, W Lu, AL Piro… - The Astrophysical …, 2023 - iopscience.iop.org
The recent detection of a repeating fast radio burst (FRB) in an old globular cluster in M81
challenges traditional FRB formation mechanisms based on the magnetic activity of young …

Localizing FRBs through VLBI with the Algonquin Radio Observatory 10 m Telescope

…, TL Landecker, AE Lanman, D Li… - The Astronomical …, 2022 - iopscience.iop.org
The Canadian Hydrogen Intensity Mapping Experiment (CHIME)/FRB experiment has detected
thousands of fast radio bursts (FRBs) due to its sensitivity and wide field of view; however…

Constraining magnetic fields through plasma lensing: application to the Black Widow pulsar

D Li, FX Lin, R Main, UL Pen… - Monthly Notices of …, 2019 - academic.oup.com
In regions with strongly varying electron density, radio emission can be magnified significantly
by plasma lensing. With magnetic fields, magnification in time and frequency will be …
