One catalogue, referred to as hyper/ultra compact (H/UC)-H II catalogue, includes 91 cores that enshroud H/UC H II regions as characterized by associated compact H40{alpha} emission. A second catalogue, referred to as pure s-cHMC, includes 31 candidate hot molecular cores (HMCs) showing rich spectra (N >= 20 lines) of complex organic molecules (COMs) and not associated with H/UC-H ii regions. The third catalogue, referred to as pure w-cHMC, includes 51 candidate HMCs with relatively low levels of COM richness and not associated with H/UC-H II regions. These three catalogues of dense cores provide an important foundation for future studies of the early stages of high-mass star formation across the Milky Way. We also find that nearly half of H/UC-H II cores are candidate HMCs. From the number counts of COM-containing and H/UC-H II cores, we suggest that the duration of high-mass protostellar cores showing chemically rich features is at least comparable to the lifetime of H/UC-H II regions. For cores in the H/UC-H II catalogue, the width of the H40{alpha} line increases as the core size decreases, suggesting that the non-thermal dynamical and/or pressure line-broadening mechanisms dominate on the smaller scales of the H/UC-H II cores.2021MNRAS.505.2801Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/505/2801CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/496/2790 : ATOMS I Description and a first look at G9.62+0.19J/MNRAS/496/2821 : ATOMS II Compact objects in ACA observations (Liu+, 2020)J/A+AS/115/81 : A CS(2-1) survey of UC HII regions (Bronfman+, 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/505/2801https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/505/2801http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/505/2801https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/505/2801https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/505/2801http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/505/2801GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/505/2801/table1 (Parameters of 91 H/UC-HII cores from the ATOMS survey's clumps)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/505/2801/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/505/2801/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/505/2801/table1?GETtext/xml+votable180.050000true135.4766-47.736150.005555555555555556Cone search capability for table J/MNRAS/505/2801/table2 (Parameters of the COM-containing but not H/UC-HII associated cores with Nline >= 20 (or pure s-cHMC))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/505/2801/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/505/2801/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/505/2801/table2?GETtext/xml+votable180.050000true128.03604-43.22940.005555555555555556Cone search capability for table J/MNRAS/505/2801/table3 (Parameters of the COM-containing but not H/UC-HII associated cores with 5 <= Nline <= 20 (or pure w-cHMC))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/505/2801/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/505/2801/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/505/2801/table3?GETtext/xml+votable180.050000true131.63937-43.909380.005555555555555556Cone search capability for table J/MNRAS/505/2801/table4 (Parameters of the 'unknown' cores (i.e. no signature of H/UC-H II nor cHMC))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/505/2801/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/505/2801/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/505/2801/table4?GETtext/xml+votable180.050000true122.38714-36.088150.0055555555555555566/28830-28831 28912-28913 28918 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 39396 41597 41653-41655 41675 41677 41683 41685 41688 41697 41759 41763 41767 41778 41804-41805 41811 41813-41814 41817 41820 42158-42159 42169 42171-42172 42207 42211 42214-42215 42224-42226 42229 42376 42379 42381 42383 42387 42390 42396 42398 42436 42445 42447 42449-42451 42454-42456 42497-42498 42512 43010 43013 43021 430266.621485433431823e-23 6.621485433431823e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/505/2801?format=asciiMillimeterRadiodefaultJ/MNRAS/505/2801/table1Parameters of 91 H/UC-HII cores from the ATOMS survey's clumpsSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
