Effects of Grazing Encounters on Spiral Galaxies
(Astronomical Society of the Pacific, 2001)
We made radio, optical and CO observations of three pairs of spiral galaxies involved in recent, grazing encounters and compared our data with numerical simulations. The tidal structures seen in the galaxy undergoing a ...
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 ...
HST observations of the interacting galaxies NGC 2207 and IC 2163
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 ...
Ocular Galaxies: NGC 2535 and its Starburst Companion NGC 2536
(The International Astronomical Union, 1999)
Interaction Between NGC 5394 and NGC 5395
(Astronomical Society of the Pacific, 1999)
The spiral galaxies NGC 5394/95 (at a distance of 47 Mpc) are involved in a recent, close, nonmerging encounter. The smaller galaxy, NGC 5394, has two long, fairly symmetric, open tidal arms (see Figure 1); in numerical ...
Dust Spirals and Acoustic Noise in the Nucleus of the Galaxy NGC 2207
Observations with the Hubble Space Telescope reveal an irregular network of dust spiral arms in the nuclear region of the interacting disk galaxy NGC 2207. The spirals extend from »50 to »300 pc in galactocentric radius, ...
