cds-question@unistra.frinfrared-sourcesx-ray-sourcespre-main-sequence-starsWe present the results of X-ray and near-infrared (NIR) observations of L1448, a star-forming region in the Perseus cloud complex using the Chandra X-Ray Observatory and the 4m telescope at the Kitt Peak National Observatory. We detect 72 X-ray sources in a ~17'x17' region with a 68 ks ACIS exposure down to the X-ray flux limit of ~10^-15^ergs/s/cm2 (0.5-8keV), for which we conduct follow-up NIR imaging observations in a concentric ~11'x11' region with FLAMINGOS down to mi_Ks_~17mag. Twelve X-ray sources have NIR or optical counterparts.2005AJ....130.2212Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/130/2212CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/478/603 : L1448 + L 1455 new Herbig-Haro flows (Bally+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/130/2212https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/130/2212http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/130/2212https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/130/2212https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/130/2212http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/130/2212GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/130/2212/table1 (ACIS photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/130/2212/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/130/2212/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/130/2212/table1?GETtext/xml+votable180.050000true51.24708330.7447220.005555555555555556Cone search capability for table J/AJ/130/2212/table3 (FLAMINGOS photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/130/2212/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/130/2212/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/130/2212/table3?GETtext/xml+votable180.050000true51.28916730.8163890.0055555555555555566/858 859 880 881https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/130/2212?format=asciiX-rayInfrareddefaultJ/AJ/130/2212/table1ACIS photometryrecnoRecord number assigned by the VizieR team.
