Morphology of 35 Repeating Fast Radio Burst Sources at Microsecond Time Scales with CHIME/FRB
Alice P. Curtin, Ketan R. Sand, Ziggy Pleunis +27
The Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) project has discovered the most repeating fast radio burst (FRB) sources of any telescope. However,…
The Massive and Quiescent Elliptical Host Galaxy of the Repeating Fast Radio Burst FRB20240209A
T. Eftekhari, Y. Dong, W. Fong +39
The discovery and localization of FRB20240209A by the Canadian Hydrogen Intensity Mapping Fast Radio Burst (CHIME/FRB) experiment marks the first repeating FRB localized with the C…
Investigating the sightline of a highly scattered FRB through a filamentary structure in the local Universe
Kaitlyn Shin, Calvin Leung, Sunil Simha +31
Fast radio bursts (FRBs) are unique probes of extragalactic ionized baryonic structure as each signal, through its burst properties, holds information about the ionized matter it e…
A VLBI Calibrator Grid at 600MHz for Fast Radio Transient Localizations with CHIME/FRB Outriggers
Shion Andrew, Calvin Leung, Alexander Li +15
The Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project has a new VLBI Outrigger at the Green Bank Observatory (GBO), which forms a 3300km baseline…
Demonstration of hybrid foreground removal on CHIME data
Haochen Wang, Kiyoshi Masui, Kevin Bandura +15
The main challenge of 21 cm cosmology experiments is astrophysical foregrounds which are difficult to separate from the signal due to telescope systematics. An earlier study has sh…
Holographic Beam Measurements of the Canadian Hydrogen Intensity Mapping Experiment (CHIME)
Mandana Amiri, Arnab Chakraborty, Simon Foreman +17
We present the first results of the holographic beam mapping program for the Canadian Hydrogen Intensity Mapping Experiment (CHIME). We describe the implementation of the holograph…
Beam Maps of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Measured with a Drone
Will Tyndall, Alex Reda, J. Richard Shaw +14
We present beam measurements of the CHIME telescope using a radio calibration source deployed on a drone payload. During test flights, the pulsing calibration source and the telesc…
A VLBI Software Correlator for Fast Radio Transients
Calvin Leung, Shion Andrew, Kiyoshi W. Masui +13
One major goal in fast radio burst science is to detect fast radio bursts (FRBs) over a wide field of view without sacrificing the angular resolution required to pinpoint them to t…
A pulsar-like swing in the polarisation position angle of a nearby fast radio burst
Ryan Mckinven, Mohit Bhardwaj, Tarraneh Eftekhari +41
Fast radio bursts (FRBs) last for milliseconds and arrive at Earth from cosmological distances. While their origin(s) and emission mechanism(s) are presently unknown, their signals…
CHIME/FRB Outriggers: KKO Station System and Commissioning Results
Adam E. Lanman, Shion Andrew, Mattias Lazda +43
Localizing fast radio bursts (FRBs) to their host galaxies is an essential step to better understanding their origins and using them as cosmic probes. The CHIME/FRB Outrigger progr…
