Study Provides New of Giant Filament Collisions in G34 Molecular Cloud

Researchers conducted a systematic study of the Galactic molecular cloud G34. The researchers revealed the collisional signatures and dynamical mechanisms of filamentary structures in this region.Using CO (J=1–0) molecular line data obtained from the 13.7 m millimeter-wave telescope at Delingha Observatory of Purple Mountain Observatory, SUN Mingke, a PhD student from the Star Formation and Evolution Group at Xinjiang Astronomic...

New Findings of A Young Pulsar’s Timing and Polarization

The researchers conducted long-term monitoring of PSR J0002+6216 with FAST. By combining four years of FAST data with nearly sixteen years of Fermi-LAT observations, they detected two glitches in this pulsar for the first time: a small g...Recently, WEI Yu, a master’s student trained jointly at the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences and Xinjiang University, under the guidanceof WANG Na and YAO Jumei, has made breakthrough progress i...

Pixel-level Analysis Reveals the True Origin of KOI-1755’s Transit Signal: Ruling out a Candidate Exoplanet

The researchers successfully revealed the genuine source of the KOI-1755 transit signal by analyzing the Target Pixel Files (TPFs) of the Kepler space telescope.KOI-1755 is a pulsating star that also shows transit-like dimming events in its Kepler photometric data. The true origin of this signal long remained uncertain.Recently, under the supervision of Prof. Ali Esamdin, PhD candidate WANG Haoz...

How Molecular Clouds Survive the Galaxy's Harsh Outskirts

a research team used the IRAM 30-meter telescope in Spain to observe a large number of molecular clouds at the Galactic edge with a Galactocentric distance of 14-22 kpc. In conjunction with the CO (1-0) data from the "Milky Way Imaging S...The outskirts of the Galaxy are ideal laboratory to study molecular clouds and star formation in a metal-poor environment. Different from the inner Galaxy (such as solar neighborhood), the molecular gas environment in this region lacks a...
