Dr. Dana Alina from Nazarbayev University has lead a team that has revealed the magnetic field structure of the ring-like molecular cloud G111 (near NGC7538, an active star forming region).

The ring shape could have several origins: it could be a remnant of a past massive supernova explosion, or very strong stellar winds; or the result of two colliding clouds of molecular gas. Each option has different magnetic signatures.

Thanks to the IRAM 30-meter telescope, the team obtained high-sensitivity observations of carbon monoxide (CO). Using the Velocity Gradients Technique, they derived a detailed magnetic blueprint of the cloud. Then, they combined these observations with data from telescopes such as the Kanata telescope (Japan) and the Planck satellite.

Their study revealed an ordered magnetic structure that follows the ring’s curvature, the same structure traced by the cold dust.

This suggests that magnetic forces were strong enough to remain organized throughout the cloud’s evolution, possibly guiding the gas motion during either an expansion or a large-scale interaction. This supports the hypotheses of G111 being a past supernova explosion remnant, or a stellar wind-blown structure.

This is not related to ALMA, but enabled by the IRAM-30m, the second largest millimeter-length radio telescope in operation. It is very dear to me because I did my first observations with it… on my namesake's day, March 8 (St. Juan de Dios). And is based in Granada, where I was born!

Annotated version an image taken by several instruments of the Herschel infrared mission.

The image shows a wispy, filamentary structure in orange filling around two thirds of the image, with some whiter, brighter highlights on the mid left and bottom center regions.

One arrow, labelled G111, points to the center of a ringed-shaped void in the top center of the image. A few bright white spots appear around the rim of the ring. Another arrow, labelled NGC 7538 (a star forming region), points to the bottom center near the brightest spots in the bottom of the image.

Figure showing magnetic fields for the G111 region, overlaid over the Plank emission (dark blue to dark brown, passing through yellow, white, and shades of orange).

There are purple line markings overlaid (Iabeled VGT ¹³CO in the legend) representing magnetic field orientation derived from carbon monoxide (¹³CO) observations using the Velocity Gradients Technique.

There are also red line segments —labeleled Starlight Polarization (H)— showing magnetic field orientations derived from polarized starlight measurements in the near-infrared H-band.

The vertical axis (labeled δ) shows Declination from approximately 61°15' to 61°45'; the horizontal axis (labeled α) shows Right ascension from about 23h20m to 23h16m.

米国：太い鎖のネックレスがMRIに引っ張り込まれ死亡
https://www.matatabi.com/2025/07/4036/, #HeavyMetalNecklace #MagneticFields #matatabinews #MRI
ニューヨーク州の病院で、太く重い金物の鎖を首に巻いた男性が、MRI（磁気共鳴画像診断機）に引きずりこまれて死亡した。亡くなったのは61歳の男性で、ウェイトトレーニング用に使う9㎏の鎖とカギを身に着けていた。男性は妻の付き添いで病院に来ていた。ひざのMRI検査終了後、妻が起き上がるのを手伝うためにMRI作動中にもかかわらず、許可なく部屋に入り事故にあった。MRIは強力な磁力と電波の力を利用して詳細な断面画像を撮影する。MRIの磁場はカギ、携帯電話、酸素ボンベなどあらゆるサイズの磁気を持つ物質を引き寄せるため、それらが飛んで患者、医療スタッフがケガをしたり、機器が壊れることがあるという。2001年には部屋の反対側に置かれた酸素ボンベが引き寄せられて飛び出し、6歳の少年が頭蓋骨骨折で死亡した例もある。
