The nearby dwarf elliptical galaxy NGC 205 offers a unique opportunity for high resolution studies of the interstellar medium in an elliptical galaxy. The present paper investigates the distribution of molecular gas, molecular line ratios, and the relationships between atomic gas, molecular gas, and dust in this galaxy. The line ratios 12 CO(2-1)/(1-0) and 12 CO(1-0)/ 13 CO(1-0) in one of the m...
متن کاملSpatial distribution of interstellar gas in the innermost 3 kpc of our Galaxy
Aims. We review the present observational knowledge on the spatial distribution and the physical state of the different (molecular, atomic and ionized) components of the interstellar gas in the innermost 3 kpc of our Galaxy – a region which we refer to as the interstellar Galactic bulge, to distinguish it from its stellar counterpart. Methods. We try to interpret the observations in the framewo...

We report the first detection of a water megamaser in a radio-loud galaxy, 3C 403, and present a follow-up study using the VLA. 3C 403 has been observed as a part of a small sample of FR II galaxies with evidence of nuclear obscuration. The isotropic luminosity of the maser is ∼ 1200 L⊙. With a recessional velocity of cz ∼ 17680 km s −1 it is the most distant water maser so far reported. The li...
متن کاملInterstellar Gas in the Ngc 4410 Galaxy Group
We present new radio continuum, 21 cm HI, and 2.6 mm CO data for the peculiar radio galaxy NGC 4410A and its companion NGC 4410B, and compare with available optical and X-ray maps. Our radio continuum maps show an asymmetric double-lobed structure, with a high surface brightness lobe extending 3.6 (∼100 kpc) to the southeast and a 6.2 (∼180 kpc) low surface brightness feature in the northwest. ...
