Probing strange quark matter objects with future space-based gravitational wave detectors DECIGO and BBO
Abdusattar Kurban, Xia Zhou, Na Wang +9
The Strange Quark Matter (SQM) hypothesis posits that objects composed of SQM could exist across a wide mass range, from strange planets (SPs) to strange stars (SSs). It has been p…
Search for continuous gravitational waves from the pulsar J0435+3233
Brian McGloughlin, Jing Ming, Maria Alessandra Papa +6
We perform a search for continuous gravitational waves from J0435+3233 using LIGO O4a public data. J0435+3233 is unique among millisecond pulsars as it exhibits an exceptionally la…
The Analysis of the Influence of Coordinate Error of Observation Station On the Construction Accuracy of Pulsar Time
Zurong Zhou, Chengshi Zhao, Yuping Gao +9
\abstract{Errors in observatory coordinates directly impact the precision of pulsar time-scale construction. Using the pulsar timing software TEMPO2, this study simulates various s…
Detectability of continuous gravitational waves from planetary-mass companions orbiting compact stars
Abdusattar Kurban, Xia Zhou, Na Wang +7
Binary systems with ultrashort-period planetary-mass companions are expected to radiate continuous gravitational waves (GWs). However, earlier studies found that the detectability…
Radio frequency interference identification using eigenvalue decomposition for multi-beam observations
Juntao Bai, Shi Dai, Na Wang +10
With the installation of next-generation phased array feed (PAF) receivers on radio telescopes, there is an urgent need to develop effective and computationally efficient radio fre…
Multi-Faceted Emission Properties of PSR J2129+4119 Observed with FAST
Habtamu Menberu Tedila, Di Li, Pei Wang +10
We present a detailed single-pulse study of the long-period pulsar PSR J2129+4119 using high-sensitivity FAST observations. Despite locating well below the traditional death line,…
