Using the MeerKAT radio telescope, astronomers from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, Germany and elsewhere, have detected 13 new pulsars in the globular cluster Omega Centauri. The finding was ...
Using the Gemini North telescope, astronomers have performed spectroscopic observations of a binary system known as SDSS J222551.65+001637.7AB. Results of the observational campaign indicate that the system consists of a ...
Polish astronomers have performed photometric observations of a short-period variable star known as NSVS 2983201. They have found that the object is a contact binary system with a mass ratio of about 0.36. The finding was ...
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, ...
Astronomers from Argentina and France have investigated the evolutionary history of an eccentric high-mass X-ray binary known as GX 301-2. Results of the study, published December 22 on the arXiv pre-print repository, deliver ...
Using the Indian Astronomical Observatory (IAO) in Hanle, India, astronomers have observed a globular cluster known as NGC 7006. Results of the study, presented December 9 on the arXiv pre-print server, yield important insights ...
Using NASA's Chandra and ESA's XMM-Newton space telescopes, astronomers from the Radboud University in the Netherlands and elsewhere have conducted X-ray observations of a tidal disruption event designated 3XMM J150052.0+015452, ...
Indian astronomers have performed long-term radio observations of a "black widow" millisecond pulsar known as PSR J1544+4937. Results of the observational campaign, published November 25 on the arXiv pre-print server, shed ...
Primordial black holes (PBHs) are fascinating cosmic bodies that have been widely investigated by astrophysicists worldwide. As suggested by their name, these are black holes believed to have appeared in the universe's early ...
