CHARACTERIZING PHYSICAL PROPERTIES OF HIERARCHICAL STRUCTURE IN THE TAURUS MOLECULAR CLOUD

Abstract

We present a comparison of the physical properties of several starless cores in the L1495-B218 central filaments of the Taurus Molecular Cloud (TMC) measured using the astrodendro and CSAR hierarchical structure analysis routines. We directly compare the physical propertiesof sources identified in NH3(1,1) integrated intensity maps from Seo et al. (2015) and H2 column density maps derived from SED-fitting of dust continuum from the Herschel Gould Belt Survey. We find that astrodendro and CSAR source sizes agree well for NH3, with a median size ratio of 1.01+0.17−0.07. We find that source sizes identified by astrodendro for H2 and by CSAR for NH3 do not agree well, with a median size ratio of 1.15+0.40−0.34. We find that source masses identified by identified by astrodendro for H2 and by overlaying CSAR detections from NH3 onto H2 do not agree well, with a median mass ratio of 1.24+1.31−0.50. We find substantial deviations between properties of sources identified byastrodendro for NH3and H2(e.g. in some cases, individual cores detected with NH3 are not distinguishable in H2).
