FAST has discovered a rare millisecond pulsar PSR J1810−0623. It spins approximately 220 times per second and forms a binary system with a carbon-oxygen white dwarf in a nearly perfect circular orbit. This discovery provides a crucial observational sample for revealing pulsar recycling mechanisms, binary evolution processes, and the magnetic field structure of the Milky Way.
Our universe's expansion is still accelerating despite recent claims suggesting otherwise, an international team of astrophysicists say. They refuted a study published last year claiming the growth of the universe is slowing and insist there is no flaw in the widely-accepted theory that a mysterious force known as dark energy is driving the expanding cosmos. The researchers, who include two Nobel Laureates and represent institutions worldwide, say the debate that followed last November’s revelations was the result of a scientific misunderstanding rather than a cosmic grenade threatening to blow apart everything we know about the universe. Their paper has been published today in Monthly Notices of the Royal Astronomical Society.
