The QUARKS survey is observing 139 massive clumps covered by 156 pointings at Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 ({lambda}~1.3mm). In conjunction with data obtained from the ALMA-ATOMS survey at Band 3 ({lambda}~3mm), QUARKS aims to carry out an unbiased statistical investigation of massive star formation process within protoclusters down to a scale of 1000au. This overview paper describes the observations and data reduction of the QUARKS survey, and gives a first look at an exemplar source, the mini-starburst Sgr B2(M). The wide-bandwidth (7.5GHz) and high-angular-resolution (~0.3") observations of the QUARKS survey allow for the resolution of much more compact cores than those could be done by the ATOMS survey, and to detect previously unrevealed fainter filamentary structures. The spectral windows cover transitions of species including CO, SO, N_2_D+, SiO, H_30_alpha, H_2_CO, CH_3_CN, and many other complex organic molecules, tracing gas components with different temperatures and spatial extents. QUARKS aims to deepen our understanding of several scientific topics of massive star formation, such as the mass transport within protoclusters by (hub-)filamentary structures, the existence of massive starless cores, the physical and chemical properties of dense cores within protoclusters, and the feedback from already formed high-mass young protostars.2024RAA....24b5009Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/24.B5009CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RAA/24.B5009https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/24.B5009http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/24.B5009https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/24.B5009https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/24.B5009http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/24.B5009GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RAA/24.B5009/tablea1 (The targets of the QUARKS survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/24.B5009/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/24.B5009/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/24.B5009/tablea1?GETtext/xml+votable180.050000true128.03829167-43.228972220.005555555555555556Cone search capability for table J/other/RAA/24.B5009/tablea2 (The continuum cores in Sgr B2(M) detected by the QUARKS survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/24.B5009/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/24.B5009/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/24.B5009/tablea2?GETtext/xml+votable180.050000true266.83403-28.384660.0055555555555555566/28808 28830-28831 28912-28913 28918 29090 29092 29094-29097 29101 29103 29113-29114 29461 29505 29509-29510 29529 29535 30218 30241 30243 30258-30259 30262-30263 30268-30269 30312 30318 30405 30425 30616 30618 37849-37850 37897 37900 38019 39246 39248 39251 41597 41653-41655 41675 41677 41683 41685 41688 41697 41759 41763 41778 41804-41805 41811 41813-41814 41817 41820 42158-42159 42169 42171-42172 42207 42211 42214-42215 42224-42226 42229 42379 42381 42383 42387 42390 42396 42398 42436 42445 42447 42449-42451 42454-42456 42497-42498 42512 43013 43021 430261.528037907652962e-22 1.528037907652962e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RAA/24.B5009?format=asciiOpticalMillimeterdefaultJ/other/RAA/24.B5009/tablea1The targets of the QUARKS surveyrecnoRecord number assigned by the VizieR team.
