Last night the skies finally cleared, and I had the chance to capture this beautiful edge-on galaxy swimming through the stars. It's called the Whale Galaxy for its shape β and I can definitely see why!

Cathie LeBlanc#SkyWatch #Astrophotography These galaxies are 25 to 30 million light years from Earth. The #WhaleGalaxy aka #NGC4631 is an edge on galaxy with so many supernovae in its starburst center that they are creating superwinds that are blowing the gas out of the galaxy. The small dwarf galaxy to its left is #NGC4627. The #HockeyStickGalaxies are #NGC4656 with #NGC4657 forming the blade. #StillLearning
Dr Kelley HessPaper accepted! Congrats Jing Wang et al. on "FEASTS: IGM cooling triggered by tidal interactions through the diffuse HI phase around NGC 4631" https://arxiv.org/abs/2301.00937. We use the incredible sensitivity of the #FAST #telescope to map a huge reservoir of neutral hydrogen around #NGC4631 (out to 120 kpc)... 1/3 #astronomy #astrodon
FEASTS: IGM cooling triggered by tidal interactions through the diffuse HI phase around NGC 4631
We use the single-dish radio telescope FAST to map the HI in the tidally interacting NGC 4631 group with a resolution of 3.24$'$ (7 kpc), reaching a 5-$Ο$ column density limit of $10^{17.9}$ cm$^{-2}$ assuming a line width of 20 km s$^{-1}$. Taking the existing interferometric HI image from the HALOGAS project of WSRT as reference, we are able to identify and characterize a significant excess of large-scale, low-density, and diffuse HI in the group. This diffuse HI extends for more than 120 kpc across, and accounts for more than one fourth of the total HI detected by FAST in and around the galaxy NGC 4631. In the region of the tidal tails, the diffuse HI has a typical column density above $10^{19.5}$ cm$^{-2}$, and is highly turbulent with a velocity dispersion around 50 km s$^{-1}$. It increases in column density with the dense HI, and tends to be associated with the kinematically ``hotter'' part of the dense HI. Through simple modeling, we find that the majority of the diffuse HI in the tail region is likely to induce cooling out of the hot IGM instead of evaporating or being radiatively ionized. Given these relations of gas in different phases, the diffuse HI may represent a condensing phase of the IGM. Active tidal interactions on-going and in the past may have produced the wide-spreading HI distribution, and triggered the gas accretion to NGC 4631 through the phase of the diffuse HI.
