Searches after Gravitational Waves Using ARizona Observatories (SAGUARO): Observations and Analysis from Advanced LIGO/Virgo's Third Observing Run
K. Paterson, M. J. Lundquist, J. C. Rastinejad +34
With the conclusion of the third observing run for Advanced LIGO/Virgo (O3), we present a detailed analysis of both triggered and serendipitous observations of 17 gravitational wav…
Swift Multiwavelength Follow-up of LVC S200224ca and the Implications for Binary Black Hole Mergers
N. J. Klingler, A. Lien, S. R. Oates +41
On 2020 February 24, during their third observing run ("O3"), the Laser Interferometer Gravitational-wave Observatory and Virgo Collaboration (LVC) detected S200224ca: a candidate…
The NANOGrav 12.5-Year Data Set: Monitoring Interstellar Scattering Delays
Jacob E. Turner, Maura A. McLaughlin, James M. Cordes +33
We extract interstellar scintillation parameters for pulsars observed by the NANOGrav radio pulsar timing program. Dynamic spectra for the observing epochs of each pulsar were used…
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…
Dispersion measure variability for 36 millisecond pulsars at 150MHz with LOFAR
J. Y. Donner, J. P. W. Verbiest, C. Tiburzi +19
Radio pulses from pulsars are affected by plasma dispersion, which results in a frequency-dependent propagation delay. Variations in the magnitude of this effect lead to an additio…
