Probing AU-Scale Magnetic-Field Reversals in the Interstellar Medium with Pulsar Scintillation

Jacob Yen, Daniel Baker, Dongzi Li +1

AU-scale structures in the interstellar medium have become relevant across several areas of astrophysics, from ISM microphysics to pulsar timing arrays and cosmic-ray (CR) propagat…

Back-End System of BURSTT

Kai-Yang Lin, Chih-Yi Wen, Homin Jiang +7

The Bustling Universe Radio Survey Telescope in Taiwan (BURSTT) is a new-generation wide-angle radio telescope specifically designed to survey Fast Radio Bursts (FRBs), energetic m…

Single Epoch Measurements of Dispersion Measure Gradients Towards PSR B0834+06

Daniel Baker, Ue-Li Pen

Understanding the evolution of pulsar dispersion measures is vital to high precision timing experiments, as well as astrometric experiments to determine pulsar positions and proper…

Transient Blurring of the Scintillation Arc of Pulsar B1737+13

Yen-Hua Chen, Samuel Siegel, Daniel Baker +2

For many pulsars, the scattering structures responsible for scintillation are typically dominated by a single, thin screen along the line of sight, which persists for years or deca…

Scintillated microlensing: measuring cosmic distances with fast radio bursts

Anna Tsai, Dylan L. Jow, Daniel Baker +1

We propose a novel means of directly measuring cosmological distances using scintillated microlensing of fast radio bursts (FRBs). In standard strong lensing measurements of cosmic…

On the cusp of cusps: a universal model for extreme scattering events in the ISM

Dylan L. Jow, Ue-Li Pen, Daniel Baker

The scattering structures in the ISM responsible for so-called ``extreme scattering events" (ESEs), observed in quasars and pulsars, remain enigmatic. Current models struggle to ex…

High Resolution VLBI Astrometry of pulsar scintillation screens with the Transform

Daniel Baker, Walter Brisken, Marten H. van Kerkwijk +2

The recent development of $θ\mhyphenθ$ techniques in pulsar scintillometry has opened the door for new high resolution imaging techniques of the scattering medium. By solving the p…

Pulsar Double-lensing Sheds Light on the Origin of Extreme Scattering Events

Hengrui Zhu, Daniel Baker, Ue-Li Pen +2

In extreme scattering events, the brightness of a compact radio source drops significantly, as light is refracted out of the line of sight by foreground plasma lenses. Despite rece…

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

Tomas Cassanelli, Calvin Leung, Mubdi Rahman +38

The CHIME/FRB experiment has detected thousands of Fast Radio Bursts (FRBs) due to its sensitivity and wide field of view; however, its low angular resolution prevents it from loca…

Interstellar Interferometry: Precise Curvature Measurement from Pulsar Secondary Spectra

Daniel Baker, Walter Brisken, Marten H. van Kerkwijk +4

The parabolic structure of the secondary or conjugate spectra of pulsars is often the result of isolated one-dimensional (or at least highly anisotropic) lenses in the ISM. The cur…

The - Diagram: Transforming pulsar scintillation spectra to coordinates on highly anisotropic interstellar scattering screens

Tim Sprenger, Olaf Wucknitz, Robert Main +2

We introduce a novel analysis technique for pulsar secondary spectra. The power spectrum of pulsar scintillation (referred to as the "secondary spectrum") shows differential delays…

A self-consistency check for unitary propagation of Hawking quanta

Daniel Baker, Darsh Kodwani, Ue-Li Pen +1

The black hole information paradox presumes that quantum field theory in curved spacetime can provide unitary propagation from a near-horizon mode to an asymptotic Hawking quantum.…
