cds-question@unistra.frgalaxiesh-i-line-emissionradial-velocityWe carried out a systematic search for nearby dwarf galaxies in the northern sky based on POSS-II film copies. As a result we present a list of 101 nearby dwarf galaxy candidates mainly of low surface brightness which have angular diameters a>0.5'. About two thirds of the objects are new discoveries. This sample is considered as a supplement to the 163 northern dwarf galaxy candidates (1998, Cat., <J/A+AS/127/409>) which have been detected in the same declination range around the known Local Volume galaxies and to the 78 dwarf galaxy candidates (1999A&AS..135..221K) in the Local Void region. All the galaxies were observed in HI with the 100-m Effelsberg radio telescope with a detection rate of 46%. The sample of detected galaxies has the following median parameters: radial velocity V_LG_=+770km/s, HI line width W_50_=46km/s, absolute blue magnitude M_B_=-13.8mag, linear diameter A_0_=2.7kpc, hydrogen mass-to-luminosity ratio M_HI_/L_B_=1.2M_{sun}_/L_{sun}_, and the HI mass-to-total mass ratio M_HI_/M_t_=0.28.2001A&A...366..428Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/366/428CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/127/409 : New nearby dwarf galaxy candidates list (Karachentseva+ 1998)J/A+AS/139/97 : HI properties of nearby galaxies (Karachentsev+, 1999)J/A+AS/141/469 : First list of the Karachentsev catalog (Huchtmeier+, 2000)J/A+AS/147/187 : Second list of the Karachentsev catalog (Huchtmeier+, 2000)J/A+A/377/801 : Fourth list of the Karachentsev catalog (Huchtmeier+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/366/428https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/366/428http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/366/428https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/366/428https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/366/428http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/366/428GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/366/428/table1 (Optical data for the new northern nearby dwarf galaxies candidates found on the POSS-II.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/366/428/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/366/428/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/366/428/table1?GETtext/xml+votable180.050000true3.6253831.3173460.0055555555555555566/514 922 948 973 1009-1010 1174 1412 1593 1918 2031 2313 2679 2690 2873 2892 3075 3250 3260 3543 3860 3889 3895 3958 4039 4062 4121 4365 4507 4602 4653 4816 5196 5471 5635 5708 5982 6035 6099 6868 6981 7189 7240 7242 7412 7471 7476 7480 7577 7623 7735 7798 8059 8120 8184 10656 10817 10839 10842 11239 11247 11450 11655 11944 13637 13645 14149 14275 14880 15603 15973 15983 16349 17905 17981 18194 19506 19604 20262 20333 21922 23312 23349 23407 23770 23794 24379 26047 26472 26997 27070 27285 27525 27826 27880 28087 28180 28356 28539 28639 30186https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/366/428?format=asciiOpticalRadiodefaultJ/A+A/366/428/table1Optical data for the new northern nearby dwarf galaxies candidates found on the POSS-II.KKHRunning numbermeta.id;meta.mainintprimaryrecnoRecord number assigned by the VizieR team.
