Research

1. MALATANG (MApping the dense moLecular gAs in the sTrongest stAr-formiNg Galaxies)

• The scientific goals of MALATANG Resolved dense gas star formation relations especially at Intermediate scales/luminosities diagnose the SF properties in different environments: nuclear vs. disk obtain the radial distribution of dense gas and SF efficiency

• I am actively working on one of the JCMT large program MALATANG, dealing with observerving preparation, data reduction, telecon orgnization and project Wiki maintanence:

• Status

  The observations has been completed in 2017, and the overall sensitivity came out as we expected; But the signals of most of the galaxies are much weaker than predicted. Affected by ozone features NGC 1097 and NGC 1365 were non-detections in either HCN or HCO+ line. HCN was not detected in NGC 2146, NGC 2903 & NGC 3521.

2. CCH in the ISM (Astrochemistry)

• I am particularly interested in the new and open topic: Astrochemistr, because chemistry is a new way to understand the composition, properties of the interstellar medium, hence the secret of star formation.
