Detection of reactive ions in the ultracompact HII regions Mon R2 and G29.96-0.02
J. R. Rizzo, A. Fuente, A. Rodriguez-Franco +1
We report the first detection of the reactive ions CO+ and HOC+ towards ultracompact (UC) HII regions, particularly in Mon R2 and G29.96-0.02. We have observed two positions in Mon…
Shocked gas layers surrounding the WR nebula NGC 2359
J. R. Rizzo, J. Martin-Pintado, J. -F. Desmurs
NGC 2359 is a Wolf-Rayet (W-R) nebula partially bound by a rather dense and warm molecular cloud. We present the results derived from CO and CO fully sampled maps of the mol…
Tracing out the Northern Tidal Stream of the Sagittarius Dwarf Spheoridal Galaxy
D. Martinez-Delgado, M. A. Gomez-Flechoso, A. Aparicio +1
The main aim of this paper is to report two new detections of tidal debris in the northern stream of the Sagittarius dwarf galaxy located at 45 arcdeg and 55 arcdeg from the center…
A new method of estimating the mass-to-light ratio of the Ursa Minor dwarf spheroidal galaxy
M. A. Gomez-Flechoso, D. Martinez-Delgado
Dwarf satellite galaxies undergo strong tidal forces produced by the main galaxy potential. These forces disturb the satellite, producing asymmetries in its stellar distribution, t…
