Using the Nanshan One-meter Wide-field Telescope (NOWT), astronomers from China have performed a photometric survey of the old open cluster NGC 188. In result, they identified many variable stars, one of which was detected ...
Quantum entanglement is perhaps one of the most intriguing phenomena known to physics. It describes how the fates of multiple particles can become entwined, even when separated by vast distances. Importantly, the probability ...

A quasiparticle is a disturbance or excitation (e.g. spin waves, bubbles, etc.) that behaves as a particle and could therefore be regarded as one. Long-range interactions between quasiparticles can give rise to a 'drag,' ...
Russian astronomers have performed spectroscopic and photometric observations of a peculiar eclipsing polar known as BS Tri. Result of this observational campaign, presented in a paper published December 23 on arXiv.org, ...
How can you figure out which points lie on a certain curve? And how many possible curves do you count by a given number of points? These are the kinds of questions Pim Spelier of the Mathematical Institute studied during ...

Using NASA's Fermi spacecraft, Chinese astronomers have investigated the variability and spectral behavior of gamma-ray flares in a distant blazar known as 3C 279. Results of the study, presented in a paper published in the ...
An international team of astronomers have performed photometric and spectroscopic observations of a Type Ibn supernova, known as SN 2023fyq. Results of the observations campaign, published May 7 on the pre-print server arXiv, ...
An international team of astronomers has employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe the eruption of Nova Vulpeculae 2021. Results of the observational campaign, published November 8 on the pre-print ...
