Generalized Non-linear Bayesian Pulsar Timing with Enterprise

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

Decades long monitoring of millisecond pulsars, which exhibit highly stable rotational periods, in pulsar timing array experiments is on the threshold of discovering nanohertz stoc…
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…

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 --…
First discovery of new pulsars and RRATs with CHIME/FRB
D. C. Good, B. C. Andersen, P. Chawla +20
We report the discovery of seven new Galactic pulsars with the Canadian Hydrogen Intensity Mapping Experiment's Fast Radio Burst backend (CHIME/FRB). These sources were first ident…
The Discovery of Nulling and Mode Switching Pulsars with CHIME/Pulsar
C. Ng, B. Wu, M. Ma +18
The Pulsar backend of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has monitored hundreds of known pulsars in the northern sky since Fall 2018, providing a rich data…
Detection of 15 bursts from FRB 180916.J0158+65 with the uGMRT
Visweshwar Ram Marthi, Tasha Gautam, Dongzi Li +5
We report the findings of a uGMRT observing campaign on FRB 180916.J0158+65, discovered recently to show a 16.35-day periodicity of its active cycle. We observed the source at 550-…
A bright millisecond-duration radio burst from a Galactic magnetar
FRB Collaboration, B. C. Andersen, K. M. Bandura +68
Magnetars are highly magnetized young neutron stars that occasionally produce enormous bursts and flares of X-rays and gamma-rays. Of the approximately thirty magnetars currently k…
