Formation of twin compact stars in low-mass X-ray binaries: Implications on eccentric and isolated millisecond pulsar populations
S. Chanlaridis, D. Ohse, D. E. Alvarez-Castillo +5
Millisecond pulsars (MSPs) are laboratories for stellar evolution, strong gravity, and ultra-dense matter. Although MSPs are thought to originate in low-mass X-ray binaries (LMXBs)…
Comparing recent PTA results on the nanohertz stochastic gravitational wave background
The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242
The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…
The second data release from the European Pulsar Timing Array I. The dataset and timing analysis
J. Antoniadis, S. Babak, A. -S. Bak Nielsen +66
Pulsar timing arrays offer a probe of the low-frequency gravitational wave spectrum (1 - 100 nanohertz), which is intimately connected to a number of markers that can uniquely trac…
The second data release from the European Pulsar Timing Array III. Search for gravitational wave signals
J. Antoniadis, P. Arumugam, S. Arumugam +95
We present the results of the search for an isotropic stochastic gravitational wave background (GWB) at nanohertz frequencies using the second data release of the European Pulsar T…
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 second data release from the European Pulsar Timing Array V. Search for continuous gravitational wave signals
J. Antoniadis, P. Arumugam, S. Arumugam +97
We present the results of a search for continuous gravitational wave signals (CGWs) in the second data release (DR2) of the European Pulsar Timing Array (EPTA) collaboration. The m…
Thermonuclear and Electron-Capture Supernovae from Stripped-Envelope Stars
Savvas Chanlaridis, John Antoniadis, David R. Aguilera-Dena +3
(abridged) When stripped from their hydrogen-rich envelopes, stars with initial masses between 7 and 11 M develop massive degenerate cores and collapse. Depending on…
