Study reveals Hot Molecular Cores Persist Throughout Massive Protostar Evolution

The researchers conducted a systematic study of a sample of protoclusters using data from the ALMA-QUARKS survey. The study reveals that massive hot cores can appear at various evolutionary stages of high-mass protostars, challenging the...Recently, MENG Dezhao, a PhD student at the Xinjiang Astronomical Observatory of the Chinese Academy of Sciences, under the guidance of Prof.LIU Tie and his supervisor Prof.Jarken Esimbek, conducted a systematic study of a sample of prot...

TESS Data Reveals Sustained Quasi-Periodic Oscillations in Multiple Blazars

The researchers searched for the periodic signal in the Transiting Exoplanet Survey Satellite (TESS) observations of blazars in the 157-month hard X-ray survey done by Swift’s Burst Alert Telescope.Quasi-periodic Oscillations have been observed rarely in the active galactic nuclei and the associated period varies from a few minutes through hours, days, weeks , and even years in all observational band of the electromagnetic spectrum...

New Methods Unlock Blazar Secrets

The researchers have applied the advanced time-series analysis methods to the one-year long Transiting Exoplanet Survey Satellite (TESS) of the radio blazar 3C 371. Blazars are the special class of active galactic nuclei (AGN) which are known to have very high variability that can be used extensively to study these compact systems and is determined by characteristic timescales. The real observationa...

Astronomers confounded by a mysterious million solar-mass dark object whose inner structure defies explanation

An international team of astronomers have uncovered what may be a new type of unseen dark object in the distant Universe that doesn’t seem to resemble anything observed before. The object, which has a mass of about one million times tha...
