An international team of astronomers have conducted a detailed study of a large ionized bubble an ultraluminous X-ray source (ULX) in the galaxy NGC 5585. Results of the research, presented in a paper published December 7 ...
An international team of astronomers has identified a new ultraluminous X-ray source (ULX) in the galaxy NGC 7090. The object, designated NGC 7090 ULX3, was found using NASA's Swift spacecraft. The finding is detailed in ...
Using ESO's Very Large Telescope (VLT), astronomers have investigated ionized gas in the central regions of the Seyfert galaxy NGC 7130. In their study, they identified a complex multi-component outflow in this galaxy. The ...
Using NASA's Chandra spacecraft, astronomers have discovered three new ultraviolet-bright radio-quiet quasars at high redshift and measured their basic X-ray properties. The newly found quasi-stellar object turns out to be ...
By analyzing data from astronomical surveys, Japanese astronomers have detected a new, extremely variable quasi-stellar object (QSO), or quasar. The newly found object, designated SDSS J125809.31+351943.0, brightened in optical ...
Using the Karl G. Jansky Very Large Array (VLA) and the upgraded Giant Meter Radio Telescope (uGMRT), astronomers have conducted multi-wavelength observations of a galaxy merger remnant known as Mrk 212. Results of this observational ...
Using the Very Long Baseline Array (VLBA), astronomers have performed high-resolution observations of the blazar PKS 1749+096. Results of this observational campaign, presented in a paper published October 23 on arXiv.org, ...
Using India's AstroSat spacecraft, astronomers have performed broadband timing and spectral observations of an ultra-luminous X-ray (ULX) pulsar known as Swift J0243.6+6124. Results of this observational campaign, presented ...
Using the Lijiang Observatory, astronomers from the Chinese Academy of Sciences (CAS) have inspected a gamma-ray blazar known as S5 0716+714. The observations provided important insights into the spectral behavior of this ...
