tl;dr: Link to paper & data at the bottom Over the past few months, Brandon Hensley, Olivier Doré, and myself have revisited the correlation between interstellar reddening by dust grains and the atomic neutral hydrogen column density. The basic idea is that HI and dust grains are well-mixed in the ISM and thus that HI can … Continue reading A new, large scale map of interstellar reddening →

This morning, my attention was brought to the new release of the Wisconsin H-Alpha Mapper Sky Survey (WHAM-SS), now covering the full sky at approximately 1 deg resolution, with velocities of +- 100 km/s and ~10 km/s spectral resolution. This first data release is only the start to further post-processing of the data, which will … Continue reading New WHAM-SS release →
