The large asymmetric HI envelope of the isolated galaxy NGC 864 (CIG 96)
NGC 864 (CIG 96) maximum
2014/12/24
We present an HI synthesis imaging study of NGC 864 (CIG 96), a spiral galaxy well isolated from similarly sized companions, yet presenting an intriguing asymmetry in its integral HI spectrum. The asy...
Star formation and feedback in smoothed particle hydrodynamic simulations - I. Isolated galaxies
star formation supernova feedback
2014/12/24
We present an analysis of star formation and feedback recipes appropriate for galactic smoothed particle hydrodynamics simulations. Using an isolated Milky Way-like galaxy, we constrain these recipes ...
Setting the Normalcy Level of HI Properties in Isolated Galaxies
atomic gas local Universe
2014/12/20
Studying the atomic gas (HI) properties of the most isolated galaxies is essential to quantify the effect that the environment exerts on this sensitive component of the interstellar medium. We observe...
The Small Isolated Gas Rich Irregular Dwarf (SIGRID) Galaxy Sample: Description and First Results
Small Isolated Irregular Dwarf Galaxy Sample: Description First Results
2011/10/12
Using an optically-unbiased selection process based on the HIPASS neutral hydrogen survey, we have selected a sample of 83 spatially isolated, gas-rich dwarf galaxies in the southern hemisphere with c...
HST-ACS photometry of the isolated dwarf galaxy VV124=UGC4879. Detection of the Blue Horizontal Branch and identification of two young star clusters

2011/10/8
We present deep V and I photometry of the isolated dwarf galaxy VV124=UGC4879, obtained from archival images taken with the Hubble Space Telescope - Advanced Camera for Surveys. In the color-magnitude...
The AMIGA sample of isolated galaxies: VIII. The rate of asymmetric HI profiles in spiral galaxies
galaxies: evolution – galaxies: interactions – galaxies: ISM – surveys – HI : galaxies
2011/9/27
(abridged) Measures of the HI properties of a galaxy are among the most sensitive interaction diagnostic at our disposal. We report here on a study of HI profile asymmetries (e.g., lopsidedness) in a ...
