Phys.org / REBELS-25 is a dynamically cold disk galaxy, observations find
An international team of astronomers has observed a high-redshift massive star-forming galaxy known as REBELS-25. They found that REBELS-25 is a dynamically cold disk galaxy. This finding was presented in a research paper ...
Phys.org / Three new RR Lyrae variable stars discovered
Using the Lulin One-meter Telescope (LOT), astronomers have observed a newly detected candidate ultra-faint dwarf galaxy known as Virgo III. As a result, they discovered three new RR Lyrae variable stars in the vicinity of ...
Phys.org / Astronomers discover merging twin quasars
Using the Subaru Telescope in Hawaii, astronomers have detected a pair of merging quasars at a high redshift, as part of the Hyper SuprimeCam (HSC) Subaru Strategic Program (SPP) survey. The serendipitous discovery is reported ...
Phys.org / Supernova SN 2023fyq exhibited long-lasting pre-explosion activity, observations show
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, ...
Phys.org / Raspberry in the sky: Astronomers discover a new supernova remnant candidate
Astronomers from the Western Sydney University in Australia and elsewhere report the detection of a new supernova remnant (SNR) candidate. The newfound SNR candidate, dubbed "Raspberry" due to its morphology, was identified ...
Phys.org / Research investigates the environment of globular cluster NGC 6355
Using the Dark Energy Camera (DECam), Argentinian astronomers have investigated the environment of a galactic globular cluster known as NGC 6355. The study, presented in a paper published May 2 on the pre-print server arXiv, ...
Phys.org / Astronomers explore globular cluster NGC 2419
Using the Indian Astronomical Observatory (IAO) and ESA's Gaia satellite, astronomers have explored a galactic globular cluster known as NGC 2419. Results of the study, published April 29 on the preprint server arXiv, shed ...
Phys.org / New accreting millisecond X-ray pulsar discovered
Astronomers report the discovery of a new pulsar using the Spektr-RG space observatory. The newfound object, designated SRGA J144459.2−604207 (or SRGA J1444 for short), turns out to be a bursting accreting millisecond X-ray ...
Phys.org / Study investigates a nearby M-dwarf binary system
Using the Very Long Baseline Array (VLBA), astronomers have explored a nearby binary stellar system composed of two M dwarfs, known as LP 349−25AB. Results of the study, presented April 25 on the pre-print server arXiv, shed ...
Phys.org / Astronomers inspect population of young stellar objects in open cluster NGC 346
