TL;DR
The HALOGAS Survey uses WSRT to observe neutral hydrogen in nearby spiral galaxies, aiming to understand cold gas accretion processes, with early results highlighting ongoing analyses of multiple targets.
Contribution
This paper provides the first overview of early results from the HALOGAS Survey, focusing on the detection and analysis of cold gas accretion in spiral galaxies.
Findings
Initial detection of neutral hydrogen in several galaxies
Insights into the characteristics of cold gas accretion
Ongoing analysis of galaxy targets
Abstract
We present early results from the ongoing Hydrogen Accretion in LOcal GAlaxieS (HALOGAS) Survey, which is being performed with the Westerbork Synthesis Radio Telescope (WSRT). The HALOGAS Survey aims to detect and characterize the cold gas accretion process in nearby spirals, through sensitive observations of neutral hydrogen (HI) 21-cm line emission. In this contribution, we present an overview of ongoing analyses of several HALOGAS targets.
