Researchers found correlations between multiband light curves of PKS 1510-089

Currently , very high-energy γ - rays have been detected in 67 BL Lac objects .These include observations in the gamma-ray band conducted by the space-based Fermi Large Area Telescope , optical and near-infrared bands observation by the...Currently, very high-energy γ-rays have been detected in 67 BL Lac objects; very high-energy γ-rays have only been detected in only 9 flat-spectrum radio quasars (FSRQs). This is because there is less absorbing medium at the TeV energ...

Researchers Discovered Annular Distribution of SiC2 towards carbon-rich AGB stars by ALMA Observations

The circumstellar envelopes ( CSE ) of asymptotic giant branch ( AGB ) stars contain a large number of molecules ( 105 have been detected ) , which account for about one-third of all molecules discovered in interstellar space ( over.Chin...The circumstellar envelopes (CSE) of asymptotic giant branch (AGB) stars contain a large number of molecules (105 have been detected), which account for about one-third of all molecules discovered in interstellar space (over 300). Studyi...

Researchers discover the gravitational collapse and accretion flows in hub filament system G323.46-0.08

Hub-filament systems are ubiquitous in molecular clouds. Most dense clumps and cores are formed in filaments and play a key role in the star formation process. Therefore, investigating the hub-filament system is one of the best ways to u...Hub-filament systems are ubiquitous in molecular clouds.

Researchers reveal the origin and lensing effect on repeating fast radio burst

Plasma lensing is the cold , non-magnetized , and inhomogeneous plasma cloud in cosmic space , which can refract the radio signal as the images with frequency-dependent properties , such as frequency-dependent dispersion measure ( DM ) ....Repeating fast radio bursts (FRBs) are mysterious radio transient sources in the universe that emit a repeating radio pulse lasting for a few milliseconds. Plasma lensing is the cold, non-magnetized, and inhomogeneous plasma cloud in cos...
