Star-formation Knots in Iras Galaxies
Images of IRAS galaxies with a range of IR properties are examined for bright knots, both within and outside the galaxy. These are found almost exclusively in galaxies with steep IR spectra, but over a wide range of IR luminosity, and usually without strong nuclear activity. In most cases, the knots are likely to be star-formation induced by tidal interactions, and are seen in the early stages ...
متن کاملCollision Induced Galaxy Formation
We present a semi-analytical model in which galaxy collisions and strong tidal interactions, both in the field and during the collapse phase of groups and clusters help determine galaxy morphology. From a semi-analytical analysis based on simulation results of tidal collisions (Aguilar & White 1985), we propose simple rules for energy exchanges during collisions that allow to discriminate betwe...
متن کاملStar formation in a clustered environment around the UCH region in IRAS 20293 + 3952
Aims. We aim at studying the cluster environment surrounding the UCH region in IRAS 20293+3952, a region in the first stages of formation of a cluster around a high-mass star. of the surroundings of the UCH region. We studied the kinematics of the region and computed the rotational temperature and column density maps by fitting the hyperfine structure of N 2 H + and NH 3. Results. The den...
متن کاملStar formation and stellar populations in the Wolf - Rayet ( ? ) luminous compact blue galaxy IRAS 08339 + 6517 ,
Aims. IRAS 08339+6517 is a luminous infrared and Lyα-emitting starburst galaxy that possesses a dwarf companion object at a projected distance of 56 kpc. An H i tidal tail has recently been detected between both galaxies, suggesting that about 70% of the neutral gas has been ejected from them. Methods. We present deep broad-band optical images, together with narrow band Hα CCD images, and optic...

C57BLKS db/db (db/db) mice develop a neuropathy with features of human type 2 diabetic neuropathy. Here, we demonstrate that these mice develop transient mechanical allodynia at the early stage of diabetes. We hypothesized that nerve growth factor (NGF), which enhances the expression of key mediators of nociception (i.e. substance P [SP] and calcitonin gene<related peptide), contributes to the ...
