Formation of a tidal dwarf galaxy in the interacting system Arp 245 (NGC 2992/93)
(2000)
Among the various phenomena observed in interacting galaxies is the ejection due to tidal forces of stellar and gaseous material into the intergalactic medium and its subsequent rearranging which can lead to the formation ...
HST observations of the interacting galaxies NGC 2207 and IC 2163
(2000)
Hubble Space Telescope (HST ) images of the galaxies NGC 2207 and IC 2163 show star formation and dust structures in a system that has experienced a recent grazing encounter. Tidal forces from NGC 2207 compressed and ...
The Peculiar Rotation Curve of NGC 404
(Astronomical Society of the Pacific, 2000)
Small Galaxies Blowing Big Bubbles
(Astronomical Society of the Pacific, 2000)
Some of the lowest-mass dwarf irregular galaxies, such as Leo A, Sag DIG and Cas 1, show a characteristic distribution of their neutral interstellar medium (ISM) as observed in the 21cm line of neutral hydrogen (HI): the ...
H I Distribution in Blue Compact Dwarf Galaxies
(Astronomical Society of the Pacific, 2000)
We present VLA HI observations and preliminary results for two dwarf galaxies, Haro 2 (Mrk 33) and Haro 4 (Mrk 36, which are currently experiencing a burst of star formation. We analyze the distribution and kinematics of ...
X-Ray Observations of Superbubbles in Dwarf Galaxies
(Revista Mexicana de Astronom a y Astrof sica, 2000)
There is plenty of evidence from neutral hydrogen observations for a violent interstellar medium, dominated by hot-plasma filled superbubbles. However, there are few direct observations of their thermal X-ray emission from ...
A Bird's Eye View of Ocular Galaxies
(Astronomical Society of the Pacific, 2000)
Ocular galaxies are systems undergoing an in-plane, near grazing, prograde encounter. In addition to the interaction causing the formation of two long, symmetrically opposite tidal tails, during a short period after ...
Tidal Dwarf Galaxies in the Interacting System NGC 2992/2993
(Astronomical Society of the Pacific, 2000)
We present multi-wavelength results and numerical simulations of the interacting system NGC 2992/2992 (Arp 245). This pair is composed of two colliding spiral galaxies out of which emanate long stellar tails and a bridge. ...
