Massive star formation driven by Colliding Filaments in Cloud F-NE

The researchers have uncovered clear evidence that two large-scale filamentary structures are colliding and merging, a process that is effectively triggering the formation of massive stars.A recent study finished by Dr. MA Yingxiu from the Xinjiang Astronomical Observatory of the Chinese Academy of Sciences and her collaborators, have uncovered clear evidence that two large-scale filamentary structures are colliding and me...

Researchers Unravel the Mystery of an OH Megamaser

Researchers conducted a high-resolution study of the OH MegaMaser emission in the ultraluminous infrared galaxy (ULIRG) IRAS 15250+3609, and revealed the nature and structure of the OH MegaMaser emission in the galaxy.Using 1665/1667 MHz OH line and continuum spectrum observational data from the European VLBI Network (EVN) and the Multi-Element Radio Linked Interferometer Network (MERLIN), Antneh Gashaye, a PhD student from the Xinjiang Astronomical O...

Formaldehyde Unravels New Insights into Star Formation in Cygnus-X

The researchers conducted deep observations of the 6-cm formaldehyde (H₂CO) absorption line and H110α recombination line toward the Cygnus-X region (∼9 deg²) using the NanShan 26-meter Radio Telescope. This work has produced the firs...The Cygnus-X region, as an important star-forming area within the Milky Way, has long been a focus of research concerning the physical conditions and dynamical evolution of its molecular cloud structures.In a recent study published in Mo...

Researchers Discover an End-Dominated Collapse and Hub-filament System in G53 Star-Forming Region

The researchers conducted a systematic study of the filamentary structure within the G53 molecular cloud. By combining multi-wavelength observations and simulations, they revealed for the first time that the filament is undergoing an "en...Recently, MENG Dezhao, a PhD student in the Star Formation and Evolution group at the Xinjiang Astronomical Observatory, Chinese Academy of Sciences, and his collaborators conducted a systematic study of the filamentary structure within ...

AI Atmospheric Calibration Precision for the NanShan 26-m Radio Telescope

By conducting spectral analysis on long-term GNSS observations at the Nanshan station, the researchers found clear annual and semi-annual cycles in ZTD variation, with higher delays in summer and lower in winter. These variations closely...Electromagnetic waves slow down as they pass through the Earth's atmosphere due to variations in air density and water vapor content, resulting in what is known as "tropospheric delay." This delay is considered a major source of error in...

How Emission Height Affects Pulse Nulling in Pulsars

The researchersalso find that pulsars sending out radio signals from lower heights display a wide range in how often they go to null. But when the radio waves come from higher up, pulsars tend to emit more consistently.A radio pulsar is like a cosmic lighthouse. It is a super dense and rapidly rotating star that “shoots out” beams of signal in the form of radio waves. If the Earth happens to be in the path, a “pulse” of radio waves will be detected...
