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...
