ATOMS + QUARKS

QUARKS Survey

Using ALMA's sharpest eyes to explore the birthplaces of massive stars and reveal how their earliest groups assemble.

QUARKS (Querying Underlying mechanisms of massive star formation with ALMA-Resolved gas Kinematics and Structures) follows dense star-forming protoclusters from the ATOMS sample to smaller physical scales, combining target catalogs, continuum products, and multi-scale image atlases to study fragmentation, core formation, gas kinematics, accretion flows, feedback, and the early evolution of massive star-forming regions.

Survey Scope

Connecting clump-scale environments to the birthplaces of massive stars

ATOMS established a uniform ALMA Band 3 view of active massive star-forming regions. QUARKS extends this foundation with higher-resolution Band 6 observations, targeting the internal structure and kinematics of dense star-forming protoclusters.

This website is designed as the public entry point for QUARKS products: target information, continuum images and FITS files, source-by-source multi-scale atlases, publications, team information, and contact points for collaboration.
