Messier 77 (M77), also known as NGC 1068 or the Squid Galaxy, is a barred spiral galaxy in the constellation Cetus. It is about 47 million light-years (14 Mpc) away from Earth, and was discovered by Pierre Méchain in 1780, who originally described it as a nebula.

2022年11月18日 · We found an excess of 79+22−20 neutrinos associated with the nearby active galaxy NGC 1068 at a significance of 4.2 σ. The excess, which is spatially consistent with the direction of the strongest clustering of neutrinos in the Northern Sky, is interpreted as direct evidence of TeV neutrino emission from a nearby active galaxy.

2022年11月3日 · They identified evidence for neutrino emission from NGC 1068 (also known as Messier 77), a nearby active galaxy. Its properties are quite different from TXS 0506+056, which was found to be a neutrino source in 2018, leading the investigators to suggest that there might be more than one population contributing to the neutrino background. —KTS.

2024年9月18日 · We present a comprehensive multi-messenger study of NGC 1068, the prototype Seyfert II galaxy associated with high-energy neutrinos following a detection by the IceCube Neutrino Observatory.

2022年11月3日 · For the first time, an international team of scientists have found evidence of high-energy neutrino emission from NGC 1068, also known as Messier 77, an active galaxy in the constellation Cetus and one of the most familiar and well-studied galaxies to date.

2022年11月3日 · For the first time, an international team of scientists have found evidence of high-energy neutrino emission from NGC 1068, also known as Messier 77, an active galaxy in the constellation Cetus and one of the most familiar and well-studied galaxies to date. The results were published on November 4, 2022 in Science (link).

2022年2月16日 · Here we present new multi-band mid-infrared images of NGC 1068 that detail the dust temperature distribution and reaffirm the original model.

2022年1月28日 · With the aim of further investigating the nuclear mid-infrared emission of the archetypal Seyfert 2 galaxy NGC1068, here we present a fitting to the N- and Q-band Michelle/Gemini spectra. We initially test several available SED libraries, including a smooth, clumpy and two phase torus models, and a clumpy disk plus wind model.

2015年12月17日 · NGC 1068 is about 47 million light-years away in the constellation Cetus. The supermassive black hole is also one of the most obscured known, blanketed by thick clouds of gas and dust. NuSTAR's high-energy X-ray view is the first to penetrate the walls of this black hole's hidden lair.

2024年8月24日 · Our results rule out the leptonic and beta-decay scenarios in a nearly model-independent manner and support hadronic mechanisms in magnetically powered coronae if NGC 1068 is a source of high-energy neutrinos.
