The Green Bank North Celestial Cap Survey IX: Timing Follow-up for 128 Pulsars
A. E. McEwen, J. K. Swiggum, D. L. Kaplan +27
The Green Bank North Celestial Cap survey is one of the largest and most sensitive searches for pulsars and transient radio objects. Observations for the survey have finished; prio…
The black widow pulsar J1641+8049 in the optical, radio and X-rays
A. Yu. Kirichenko, S. V. Zharikov, A. V. Karpova +14
PSR J1641+8049 is a 2 ms black widow pulsar with the 2.2 h orbital period detected in the radio and -rays. We performed new phase-resolved multi-band photometry of PSR J1641+804…
Search for gravitational wave signals from known pulsars in LIGO-Virgo O3 data using the 5n-vector ensemble method
Luca D'Onofrio, Rosario De Rosa, Cristiano Palomba +16
The 5n-vector ensemble method is a multiple test for the targeted search of continuous gravitational waves from an ensemble of known pulsars. This method can improve the detection…
The NANOGrav 15-year data set: Search for Transverse Polarization Modes in the Gravitational-Wave Background
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +96
Recently we found compelling evidence for a gravitational wave background with Hellings and Downs (HD) correlations in our 15-year data set. These correlations describe gravitation…
Constraining the magnetic field geometry of the millisecond pulsar PSR~J0030+0451 from joint radio, thermal X-ray and -ray emission
J. Pétri, S. Guillot, L. Guillemot +13
With the advent of multi-wavelength electromagnetic observations of neutron stars, spanning many decades in photon energies, from radio wavelengths up to X-rays and -rays, it be…
The NANOGrav 12.5-year data set: A computationally efficient eccentric binary search pipeline and constraints on an eccentric supermassive binary candidate in 3C 66B
Gabriella Agazie, Zaven Arzoumanian, Paul T. Baker +85
The radio galaxy 3C 66B has been hypothesized to host a supermassive black hole binary (SMBHB) at its center based on electromagnetic observations. Its apparent 1.05-year period an…
