The NANOGrav 15 yr Data Set: Customized Chromatic Noise Models

Bjorn Larsen, Jeremy G. Baier, Daniel J. Oliver +53

Pulsar timing arrays conduct low-frequency gravitational wave searches, which require comprehensive accounting of various noise sources to achieve robust results. Interstellar prop…

Gravitational Wave Measurement of the - Intrinsic Scatter at High Redshift

Cayenne Matt, Kayhan Gültekin, Gabriella Agazie +109

The observed GWB spectrum is higher in amplitude than model predictions by a factor of 2-3. Using a semi-analytic model, we evaluate the effect of a high-scatter supermassive black…

HI Imaging of a Blueberry Galaxy Suggests a Merger Origin

Saili Dutta, Apurba Bera, Omkar Bait +3

Blueberry galaxies (BBs) are fainter, less massive, and lower redshift counterparts of the Green pea galaxies. They are thought to be the nearest analogues of the high redshift Lym…

Polarization Measurements of Arecibo-Sky Pulsars: Faraday Rotations and Emission-Beam Analyses

Joanna Rankin, Arun Venkataraman, Joel M. Weisberg +1

We present Faraday Rotation Measure (RM) values derived at L- and P-band as well as some 60 Stokes-parameter profiles, both determined from our longstanding Arecibo dual-frequency…

The second data release from the European Pulsar Timing Array: VI. Challenging the ultralight dark matter paradigm

Clemente Smarra, Boris Goncharov, Enrico Barausse +68

Pulsar Timing Array experiments probe the presence of possible scalar or pseudoscalar ultralight dark matter particles through decade-long timing of an ensemble of galactic millise…

The NANOGrav 15-year Gravitational-Wave Background Methods

Aaron D. Johnson, Patrick M. Meyers, Paul T. Baker +93

Pulsar timing arrays (PTAs) use an array of millisecond pulsars to search for gravitational waves in the nanohertz regime in pulse time of arrival data. This paper presents rigorou…
