Using various telescopes, an international team of astronomers has conducted a comprehensive study of a double-lined spectroscopic binary known as HD 34736. The study, published November 6 in the Monthly Notices of the Royal ...

An international team of astronomers has employed the MeerKAT radio telescope to investigate giant radio galaxies in the field of the Cosmological Evolution Survey (COSMOS). They found a new giant radio galaxy that had not ...

Astronomers from the Steward Observatory in Arizona and elsewhere report the discovery of a structure consisting of a quasi-stellar object (QSO) and a dusty star-forming galaxy (DSFG), linked by a bridge of ionized carbon. ...

An international team of astronomers has conducted a multiwavelength study of an X-ray binary designated 1eRASS J085039.9-421151. Results of the study, published Nov. 4 on the preprint server arXiv, yield new information ...

Using ESO's Very Large Telescope (VLT), an international team of astronomers has inspected an icy protoplanetary disk of a young star known as PDS 453. Results of the new study, published on the preprint server arXiv, yield ...

Astronomers have performed a comprehensive multiwavelength study of an extremely variable blazar known as AO 0235+164. Results of the new study, published Nov. 3 on the preprint server arXiv, shed more light on the long-term ...

An international team of astronomers has inspected long-term evolution of quasi-periodic eruptions (QPEs) from a QPE source designated eRO-QPE2. The study found that QPEs from this source are remarkably stable over the investigated ...

Using the CHIME telescope, an international team of astronomers has detected a new repeating fast radio burst (FRBs) source in the outskirts of a quiescent galaxy. The finding of a new FRB, which experienced 22 repeating ...

Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers have observed a giant spiral galaxy designated ADF22.A1. Results of the observational ...

Using the Gemini-South telescope, astronomers have performed high-resolution near-infrared spectroscopy of stars in a Galactic globular cluster known as Gran 5. They found that this cluster harbors two stellar populations ...

Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 candidate supergiant stars in the Andromeda and Triangulum galaxies. The finding was reported in ...

Astronomers from the University of Wisconsin–Madison and Harvard–Smithsonian Center for Astrophysics (CfA) have inspected a Galactic open cluster known as NGC 2506 as part of the WIYN Open Cluster Study. Results of the study, ...

By analyzing the data from the Dark Energy Camera Legacy Survey (DECaLS), astronomers have discovered a new tidal tail likely associated with the galaxy NGC 3785. The newly detected tidal tail is extremely extended and faint. ...

Astronomers have employed the Canada-France-Hawaii Telescope (CFHT) to perform comprehensive multiwavelength observations of a large and massive spiral galaxy known as UGC 2885. Results of the observational campaign, published ...

Astronomers from the University of Southern Queensland (UniSQ) in Australia and elsewhere have reinvestigated a planetary system known as HD 28185, known to contain a gaseous giant exoplanet and an outer companion, believed ...
