cds-question@unistra.frgalaxiessupernovaephotometryThe Pan-STARRS1 (PS1) survey has obtained imaging in five bands (griz y_P1_) over 10 Medium Deep Survey (MDS) fields covering a total of 70 square degrees. This paper describes the search for apparently hostless supernovae (SNe) within the first year of PS1 MDS data with an aim of discovering superluminous supernovae (SLSNe). A total of 249 hostless transients were discovered down to a limiting magnitude of M_AB_~23.5, of which 76 were classified as Type Ia supernovae (SNe Ia). There were 57 SNe with complete light curves that are likely core-collapse SNe (CCSNe) or type Ic SLSNe and 12 of these have had spectra taken. Of these 12 hostless, non-Type Ia SNe, 7 were SLSNe of type Ic at redshifts between 0.5 and 1.4. This illustrates that the discovery rate of type Ic SLSNe can be maximized by concentrating on hostless transients and removing normal SNe Ia. We present data for two possible SLSNe; PS1-10pm (z=1.206) and PS1-10ahf (z=1.1), and estimate the rate of type Ic SLSNe to be between 3^+3^_-2_x10^-5^ and 8^+2^_-1_x10^-5^ that of the CCSN rate within 0.3<=z<=1.4 by applying a Monte Carlo technique. The rate of slowly evolving, type Ic SLSNe (such as SN2007bi) is estimated as a factor of 10 lower than this range.2015MNRAS.448.1206Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/448/1206CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/750/99 : The Pan-STARRS1 photometric system (Tonry+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/448/1206https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/448/1206http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/448/1206https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/448/1206https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/448/1206http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/448/1206GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/448/1206/table3 (The 28 spectroscopically confirmed PS1 SN Ia)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/448/1206/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/448/1206/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/448/1206/table3?GETtext/xml+votable180.050000true36.8001-4.53470.005555555555555556Cone search capability for table J/MNRAS/448/1206/table4 (The 48 plausible PS1 SN Ia, classified using the soft and psnid photometric classification codes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/448/1206/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/448/1206/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/448/1206/table4?GETtext/xml+votable180.050000true34.6005-4.20330.005555555555555556Cone search capability for table J/MNRAS/448/1206/table5 (*The 12 confirmed PS1 CCSNe)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/448/1206/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/448/1206/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/448/1206/table5?GETtext/xml+votable180.050000true162.115557.15260.005555555555555556Cone search capability for table J/MNRAS/448/1206/table6 (*The 17 plausible PS1 CCSNe)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/448/1206/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/448/1206/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/448/1206/table6?GETtext/xml+votable180.050000true35.4861-3.83690.005555555555555556Cone search capability for table J/MNRAS/448/1206/tablea2 (The 28 SN-like orphans)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/448/1206/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/448/1206/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/448/1206/tablea2?GETtext/xml+votable180.050000true35.5355-5.19260.005555555555555556Cone search capability for table J/MNRAS/448/1206/tablea3 (The 116 unknown orphans)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/448/1206/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/448/1206/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/448/1206/tablea3?GETtext/xml+votable180.050000true35.0206-4.06090.0055555555555555565/1517 1629 2538 2744 2856 4696-4697 4758 6814 6/6047 6076 6078-6079 6112 6120 6494-6495 6513 6515 6524 7178 7200 10147 10150 10156 10158 10743 10749 10935 10958-10959 10980-10982 10985 11430 11432-11433 11520-11521 11524 17682-17683 17688-17689 17691-17692 17694-17695 17713 17716-17717 18766 18793 18796 19026-19027 19036-19038 27244-27245 27247 27250 27333 27344 35933-35934 35956-35957 36104 361062.293819389918797e-19 4.1263914509788833e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/448/1206?format=asciiOpticaldefaultJ/MNRAS/448/1206/table3The 28 spectroscopically confirmed PS1 SN IaFieldFieldmeta.id;obs.fieldcharrecnoRecord number assigned by the VizieR team.
