Generalized Non-linear Bayesian Pulsar Timing with Enterprise
Andrew R. Kaiser, Jeffrey S. Hazboun, Maura A. McLaughlin +56
In this study, we use the Bayesian methods in the Enterprise package to examine the fully general parameterization of pulsar timing models in tandem with noise. We investigate four…
Power-law distribution and scale-invariant structure from the first CHIME/FRB Fast Radio Burst catalog
Zi-Han Wang, Yu Sang, Xue Zhang
We study the statistical property of fast radio bursts (FRBs) based on a selected sample of 190 one-off FRBs in the first CHIME/FRB catalog. Three power law models are used in the…
CHIME Discovery of a Binary Pulsar with a Massive Non-Degenerate Companion
Bridget C. Andersen, Emmanuel Fonseca, J. W. McKee +25
Of the more than radio pulsars currently known, only are in binary systems, and only five of these consist of young pulsars with massive non-degenerate compan…
Nanohertz Gravitational Wave Astronomy during the SKA Era: An InPTA perspective

Sub-second periodicity in a fast radio burst
FRB Collaboration, Bridget C. Andersen, Kevin Bandura +59
Fast radio bursts (FRBs) are millisecond-duration flashes of radio waves that are visible at distances of billions of light-years. The nature of their progenitors and their emissio…
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…
The First CHIME/FRB Fast Radio Burst Catalog
FRB Collaboration, Mandana Amiri, Bridget C. Andersen +73
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 MHz fro…
Refined Mass and Geometric Measurements of the High-Mass PSR J0740+6620
Emmanuel Fonseca, H. Thankful Cromartie, Timothy T. Pennucci +42
We report results from continued timing observations of PSR J0740+6620, a high-mass, 2.8-ms radio pulsar in orbit with a likely ultra-cool white dwarf companion. Our data set consi…
High Precision Measurements of Interstellar Dispersion Measure with the upgraded GMRT
M. A. Krishnakumar, P. K. Manoharan, Bhal Chandra Joshi +19
Pulsar radio emission undergoes dispersion due to the presence of free electrons in the interstellar medium (ISM). The dispersive delay in the arrival time of pulsar signal changes…
LOFAR Detection of 110-188 MHz Emission and Frequency-Dependent Activity from FRB 20180916B
Z. Pleunis, D. Michilli, C. G. Bassa +32
FRB 20180916B is a well-studied repeating fast radio burst source. Its proximity (~150 Mpc), along with detailed studies of the bursts, have revealed many clues about its nature --…
