Detecting Intermediate-mass Black Holes Using Miniature Pulsar Timing Arrays in Globular Clusters
Xian Chen, Verónica Vázquez-Aceves, Siyuan Chen +3
Theoretical models predict that intermediate-mass black holes (IMBHs) exist in globular clusters (GCs), but observational evidence remains elusive. Millisecond pulsars (MSPs), whic…
Reading signatures of supermassive binary black holes in pulsar timing array observations
Boris Goncharov, Shubhit Sardana, A. Sesana +10
We find the inferred properties of the putative gravitational wave background in the second data release of the European Pulsar Timing Array to be in better agreement with theoreti…
Quasars can Signpost Supermassive Black Hole Binaries
J. Andrew Casey-Clyde, Chiara M. F. Mingarelli, Jenny E. Greene +3
Supermassive black holes (SMBHs) are found in the centers of massive galaxies, and galaxy mergers should eventually lead to SMBH mergers. Quasar activity has long been associated w…
A Gaussian-processes approach to fitting for time-variable spherical solar wind in pulsar timing data
Iuliana C. Niţu, Michael J. Keith, Caterina Tiburzi +26
Propagation effects are one of the main sources of noise in high-precision pulsar timing. For pulsars below an ecliptic latitude of , the ionised plasma in the solar wind…
Applying clock comparison methods to pulsar timing observations
Siyuan Chen, Francois Vernotte, Enrico Rubiola
Frequency metrology outperforms any other branch of metrology in accuracy (parts in ) and small fluctuations (). In turn, among celestial bodies, the rotation…
Response and Uncertainty of the Parabolic Variance PVAR to Non-Integer Exponents of the Power Law
François Vernotte, Siyuan Chen, Enrico Rubiola
Oscillator fluctuations are described as the phase or frequency noise spectrum, or in terms of a wavelet variance as a function of the measurement time. The spectrum is generally a…
Pulsar science with data from the Large European Array for Pulsars
J. W. McKee, C. G. Bassa, S. Chen +12
The Large European Array for Pulsars (LEAP) is a European Pulsar Timing Array project that combines the Lovell, Effelsberg, Nançay, Sardinia, and Westerbork radio telescopes into a…
