Constraints on Supermassive Black Hole Binaries from the Lack of Resolvable Sources in the NANOGrav 15-yr Dataset

Emiko C. Gardiner, Kayhan Gültekin, Philippe Turgeon +116

Pulsar timing arrays (PTAs) have found evidence of a gravitational wave background (GWB) consistent with a population of supermassive black hole binaries (SMBHBs), but have not yet…

The October 2022 flare in OJ 287 and the mass of its primary black hole

Mauri J. Valtonen, Staszek Zola, Manpreet Singh +21

The bright blazar OJ~287 has demonstrated a sequence of flares, which are well explained by a quasi-Keplerian orbit model. The flares are associated with the impact of the secondar…

QuickGWecc: Fast Bayesian pipeline for searching eccentric binaries in pulsar timing array data

Lankeswar Dey, Bence Bécsy, Abhimanyu Susobhanan +1

Recent pulsar timing array (PTA) results have provided evidence for the presence of a nanohertz gravitational wave (GW) background, most likely originating from a population of sup…

Mitigating the Timing Impact of Anomalous Pulse Profile Shape Variability in PSR J1713+0747 with Gaussian Component Modeling

Shania A. Nichols, Michael T. Lam, Gabriella Agazie +31

The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) achieves sub-microsecond timing precision for several millisecond pulsars in its pulsar timing array (PT…

The NANOGrav 15 yr and 20 yr Datasets: Timing Events and Pulse Shape Changes

Ben Jacobson-Bell, James M. Cordes, Shami Chatterjee +61

The average pulse shape of a pulsar is typically stable over decadal timescales, enabling estimation of pulse times of arrival to better than a small fraction of the pulse width us…

The GMRT High-Resolution Southern Sky Survey for pulsars and transients -- VIII: Orbital Variability and the Evolution of a 1-Day He-WD Millisecond Pulsar J2101-4802

Ankita Ghosh, Bhaswati Bhattacharyya, David L. Kaplan +8

We present timing and orbital phase-resolved polarimetry of the millisecond pulsar (MSP) J21014802, having a spin period of 9.48~ms and dispersion measure (DM) $25.05\ \mathrm{p…
