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 ESO's Very Large Telescope (VLT) and the Hubble Space Telescope (HST), astronomers have inspected the globular cluster NGC 2808. Results of the study, published December 2 on the arXiv pre-print repository, shed more ...
Japanese astronomers have performed long-term multiwavelength observations of a supernova remnant (SNR) designated SNR G298.6−0.0. They found that G298.6−0.0 is an old SNR interacting with molecular clouds. The new findings ...
Clues to a black hole's origins can be found in the way it spins. This is especially true for binaries, in which two black holes circle close together before merging. The spin and tilt of the respective black holes just before ...

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, ...
By analyzing the data from ESA's XMM-Newton and Gaia satellites, astronomers have investigated a young star cluster known as NGC 2264. Results of the study, published November 16 on the arXiv pre-print repository, shed more ...
Astronomers have analyzed new and archival multiwavelength observations of the active galaxy NGC 5273. As a result, they detected so-called "changing-look" events in the active galactic nucleus of this galaxy. The finding ...
Astronomers report the detection of four new pulsars using the Giant Metrewave Radio Telescope (GMRT) as part of the GMRT High Resolution Southern Sky (GHRSS) survey. The finding was detailed in a research paper published ...
