Taurus to Gemini in HDR

I've been experimenting with HDR astrophotography. The photo covers the region Taurus to Gemini and is composed of a set of 20s untracked exposures, stacked using Sequator. I used Photoshop, the Gradient Xterminator plug-in to subtract the bright sky-glow of a nearly full Moon, and AuroraHDR to bring out the fainter stars and nebulae. My camera is the Fujifilm X-A3.

ALMA Reveals crazy kinematics around the black hole in NGC 1068

A new paper on NGC 1068, this time using the longest baselines currently available with ALMA. The molecular disk surrounding the central, supermassive black hole shows remarkably strange motions, and we are finding more evidence that free-free emission dominates the radio continuum. The preprint is available on arXiv.

The picture shows the radial velocities of molecular gas traced by HCN J=3-2 emission. This larger scale figure didn't make the paper, but it's fun to stare at.
