Novel standard candle: Collapsing axion stars
Haoran Di, Lijing Shao, Zhu Yi +1
The Hubble constant, , is a crucial parameter in cosmology. However, various cosmic observations have produced differing posterior values for , resulting in what is refer…
Constraints on conformal ultralight dark matter couplings from the European Pulsar Timing Array
Clemente Smarra, Adrien Kuntz, Enrico Barausse +15
Millisecond pulsars are extremely precise celestial clocks: as they rotate, the beamed radio waves emitted along the axis of their magnetic field can be detected with radio telesco…
Spectral instability of black holes: relating the frequency domain to the time domain
Yiqiu Yang, Zhan-Feng Mai, Run-Qiu Yang +2
Recent work has shown that the quasinormal mode spectrum of black holes is unstable under small perturbations (of order ) of the radial potential, while the early time-domain r…
