We show that constraints to this mysterious component based upon large-scale structure nicely complement the SN Ia data, and that together they require ${$\u03a9${}}_{X}\\phantom{\\rule{0ex}{0ex}}=\\phantom{\\rule{0ex}{0ex}}{$\u03c1${}}_{X}/{$\u03c1${}}_{\\mathrm{crit}}$\ud835\udfc4${}(0.6,0.7)$ and ${w\\phantom{\\rule{0ex}{0ex}}=\\phantom{\\rule{0ex}{0ex}}p}_{X}/{$\u03c1${}}_{X}<$-${}0.6$ ( $95%$ C.L.), for the favored flat Universe. Other cosmological data support this conclusion. The simplest explanation, a cosmological constant, is consistent with this, while some of the other possibilities are not.", "title": "Constraining Dark Energy with Type Ia Supernovae and Large-Scale Structure", "type": "article-journal", "id": "1233929" }
