Dark Matter in Dwarf Galaxies: Latest Density Profile Results
We present high-resolution two-dimensional velocity fields in Hα and CO of the nearby dwarf galaxy NGC 2976. Our observations were made at both higher spatial resolution (∼ 75 pc) and higher velocity resolution (13 km s in Hα and 2 km s in CO) than most previous studies. We show that NGC 2976 has a very shallow dark matter density profile, with ρ(r) lying between ρ ∝ r and ρ ∝ r. We carefully t...
متن کاملThe local space density of dwarf galaxies
We estimate the luminosity function of Ðeld galaxies over a range of 10 mag for ([22 \ M BJ \ [12 km s~1 Mpc~1) by counting the number of faint APM galaxies around Stromlo-APM redshift H 0 \ 100 survey galaxies at known distance. The faint end of the luminosity function rises steeply at M BJ B [15, implying that the space density of dwarf galaxies is at least 2 times larger than predicted by a ...
متن کاملfunctional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner
نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...
A Universal Mass Profile for Dwarf Spheroidal Galaxies?
We apply the Jeans equation to estimate masses for eight of the brightest dwarf spheroidal (dSph) galaxies. For Fornax, the dSph with the largest kinematic data set, we obtain a model-independent constraint on the maximum-circular velocity, Vmax = 20 +4 −3 km s . Although we obtain only lowerlimits of Vmax & 10 km s −1 for the remaining dSphs, we find that in all cases the enclosed mass at the ...
متن کاملDwarf Galaxies in Clusters: the Effects of a Violent Environment
New observations suggest that dwarf galaxies pervade the universe, for they have been encountered in large numbers in the field (Marzke et al. 1998), groups (Côté et al. 1977), and clusters of galaxies (e.g. Trentham 1998). Some early studies encountered an over-abundance of dwarfs in clusters (e.g. Sandage et al. 1985) in the nearby universe. Studies at higher redshifts also suggested large nu...
