Herschel Spectroscopic Observations of Little Things Dwarf Galaxies
We present far-infrared (FIR) spectral line observations of five galaxies from the Little Things sample: DDO 69, DDO 70, DDO 75, DDO 155, and WLM. While most studies of dwarfs focus on bright systems or starbursts due to ...
The Stellar and Gas Kinematics of the LITTLE THINGS Dwarf Irregular Galaxy NGC 1569
In order to understand the formation and evolution of Magellanic-type dwarf irregular (dIm) galaxies, one needs to understand their three-dimensional structure. We present measurements of the stellar velocity dispersion ...
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 ...
