Probing the Central Engine of Supermassive Black Holes throughJet Magnetic-field Measurements of Blazar 1156+295

Researchers revealed the physical picture of magnetically driven shocks deep within the jet of blazar 1156+295.In the vast depths of the universe, blazars, with their extreme relativistic jets pointing directly at Earth, act as cosmic energy hubs connecting supermassive black holes (SMBHs) to the vast cosmic environment. However, the physical dri...

How Massive Stars Get Their Mass: SDC335 Reveals an Inverted Infall Velocity Profile

Results of a recent study show that the gas motions in SDC335.579-0.292 cannot be fully described by the conventional assumption that collapse simply becomes faster toward the centre. Instead, the cloud exhibits an inverted infall veloci...Massive stars shape the interstellar medium through intense radiation, stellar winds, and eventual supernova explosions. They play an important role in galaxy evolution and also influence the formation and evolution of nearby low-mass st...

Boundary-Layer Turbulence and Wind-Field Monitoring at the Muztagh-ata Station

The researchers used coherent Doppler wind lidar to carry out long-term wind-profile observations at the North-1 site of the Muztagh-ata station. By combining these data with simultaneous measurements from a seeing monitor and a 30-meter...Ground-based optical astronomical observations must pass through Earth’s atmosphere. Image motion of stars caused by atmospheric turbulence can severely affect optical astronomical observations. Under the supervision of his advisor, Ail...

Three High-Amplitude δ Scuti Stars Show Unexpected Pulsation Complexity

Using high-precision short-cadence data from TESS, researchers discovered and analyzed three new HADS: TIC 408074920, TIC 189714989, and TIC 34137913. Their pulsation properties were investigated using Fourier analysis, sliding-window am...High-Amplitude δ Scuti stars (HADS) are intermediate-mass pulsating variables traditionally considered to be dominated by radial pulsations, making them important probes of stellar structure and evolution. However, recent high-precision...

A Multitracer Analysis of the Sh2-252 A-B Star-Forming Region: Hub-Filament System

The researchers conducted a study of the star forming region Sh2-252 A-B using ammonia data obtained with the Nanshan 26-m radio telescope and many other data such as CO from PMO 14m telescope. Recently, international PhD student Serikbek Sailanbek from the Star Formation and Evolution Group at the Xinjiang Astronomical Observatory, Chinese Academy of Sciences, conducted a study of the star forming region Sh2-252 A-B using ammo...

Observational Evidence of Bidirectional Solar Jets Driven by Magnetic Reconnection

Using sub-arcsecond high-resolution observations from the Goode Solar Telescope (GST) and the Solar Dynamics Observatory (SDO) , researchers reveal the process of lower-atmosphere magnetic reconnection driving bidirectional plasma jets a...Magnetic reconnection is the core physical process of energy release in the solar atmosphere, triggering and driving various scales of solar eruptive activities, including flares, coronal mass ejections (CMEs), and different types of jet...
