GHASP: an H α kinematical survey of spiral galaxies - XIII. Distribution of luminous and dark matter in spiral and irregular nearby galaxies using H α and H I rotation curves and WISE photometry
M. Korsaga, B. Epinat, P. Amram, C. Carignan, P. Adamczyk and A. SorghoWe present the mass models of 31 spiral and irregular nearby galaxies obtained using hybrid rotation curves (RCs) combining high-resolution GHASP Fabry-Perot Hα RCs and extended WHISP H I ones together with 3.4 μm WISE photometry. The aim is to compare the dark matter (DM) halo properties...
