Context. Orion-KL is a remarkable, nearby star-forming region where a recent explosive event has generated shocks that could have released complex molecules from the grain mantles. Aims: A comparison of the distribution of the different complex molecules will help in understanding their formation and constraining the chemical models. Methods: We used several data sets from the Plateau de Bure Interferometer to map the dimethyl ether emission with different arcsec spatial resolutions and differ...
Segue 2, discovered by Belokurov et al. (2009), is a galaxy with a luminosity
of only 900 L_sun. We present Keck/DEIMOS spectroscopy of 25 members of Segue
2--a threefold increase in spectroscopic sample size. The velocity dispersion
is too small to be measured with our data. The upper limit with 90% (95%)
confidence is sigma_v < 2.2 (2.6) km/s, the most stringent limit for any
galaxy. The corresponding limit on the mass within the 3-D half-light radius
(46 pc) is M_1/2 < 1.5 (2.1) x 10^5...
