By analyzing the available data from various space observatories and ground-based telescopes, Indian astronomers have conducted a long-term multiwavelength study of a changing-look active galactic nucleus (AGN) known as NGC ...

Using various space telescopes, an international team of astronomers have observed a newly detected very faint X-ray transient designated 4XMM J174610.7–290020. Results of the observational campaign, published October 2 on ...

An international team of astronomers has used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a well-known quasar known as the Cloverleaf. As part of the observations, they serendipitously discovered a ...

Using ESA's XMM-Newton satellite, astronomers have conducted deep observations of a massive galaxy known as NGC 5746. As a result, they detected a hot gaseous outflow in the galaxy. The new findings, presented Oct. 1 on the ...

Astronomers from Australia and Serbia have performed multi-band photometric observations of a binary star known as V717 Andromedae. The observations yielded crucial information regarding the properties of V717 Andromedae, ...

Using the Very Energetic Radiation Imaging Telescope Array System (VERITAS), German astronomers have observed a unique microquasar known as SS 433. Results of the observational campaign, published Sept. 25 on the arXiv pre-print ...

Astronomers report the discovery of two new highly scattered pulsars as part of the Australian SKA Pathfinder (ASKAP) Variables and Slow Transients (VAST) survey. The findings are detailed in a research paper published September ...

Astronomers from South Africa have conducted multi-band observations of a nearby dwarf irregular galaxy known as UGCA 320. Results of the observational campaign, recently published on the arXiv preprint server, yield important ...

Astronomers from Curtin University in Australia and elsewhere have performed radio observations of a tidal disruption event known as AT2019azh. Results of the new study, published September 22 on the arXiv preprint server, ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two new exoplanets around a young sun-like star known as TOI-6109. The newfound alien worlds are slightly larger than Neptune and orbit ...

Astronomers report the discovery of a rare nova super-remnant surrounding the recurrent nova LMCN 1971-08a in the Large Magellanic Cloud (LMC). This is the first nova super-remnant identified in the LMC. The findings are ...

An international team of astronomers has performed photometric and spectroscopic observations of a compact stellar system around a nearby spiral galaxy known as NGC 7531. Results of the observational campaign, published September ...
