A galactic merger is a chaotic event. When two massive structures like galaxies merge, their powerful gravitational forces wrench stars out of their usual orbits in a process called violent relaxation. In essence, the merging galaxies are evolving rapidly, and small perturbations can be amplified as the system moves toward a more stationary state. Intuition suggests that this chaos should disrupt the galaxy, including its star formation, but new observations of the Arp 220 galaxy merger show that something else happens: the merger creates a massive magnetic field that traps gas and encourages more stars to form. Arp 220 is one of the closest galaxy mergers to us. It’s also extremely bright in infrared and is considered to be the prototypical ULIRG—an Ultraluminous Infrared Galaxy. It’s the result of two spiral galaxies merging. The galaxies are gas-rich, which triggers starburst activity in Arp 220’s central regions. In new research, scientists from the Harvard and Smithsonian Center for Astrophysics and other institutions probed these central regions with the Submillimeter Array on Maunakea in Hawaii to better understand the magnetic fields. The research is “Polarized Dust Emission in Arp220: Magnetic Fields in the Core of an Ultraluminous Infrared Galaxy.” It will be published in the Monthly Notices of the Royal Astronomical Society, and the lead author is David Clements from the Department of Physics at Imperial College in the UK. ULIRGs are characterized by intense star formation and extreme luminosity in the infrared. “Arp 220 is the merger of two gas-rich spiral galaxies and hosts a massive starburst forming stars at a rate of ~ 100 solar masses per year,” the authors explain. The star formation is concentrated in two distinct nuclei in Arp 220’s center. Since Arp 220 is the prototypical ULIRG, it’s a natural laboratory and a case study for understanding these objects and their starburst nature. The researchers aimed the Submillimeter Array (SMA) at Arp 220’s central regions to detect polarized light coming from polarized dust there. Since dust grains align themselves with magnetic fields, the SMA can detect and characterize magnetic fields by measuring polarity. “Despite the potential impact of magnetic fields on galaxy structure, sub-mm observations of polarization in extragalactic sources remain sparse,” the authors explain in their paper. The first large-scale effort to measure this polarization was in 2002 when researchers published the first galaxy-averaged detection of sub-mm polarization. SOFIA (Stratospheric Observatory for Infrared Astronomy) provided another limited sample of dust polarization observations, but SOFIA ended in 2022. Other efforts were made to detect the magnetic fields in the starburst regions, but they lacked the resolution to see the two regions separately. If each region or nuclei had different polarizations, the low resolution would dilute the polarization, possibly even making the magnetic fields undetectable. The authors explain that their efforts have overcome this problem. “We here present the results of sub-mm polarization observations of Arp220 at subarcsecond resolution using the Submillimeter Array. These are capable of resolving the separate nuclei and thus avoiding this dilution problem,” the authors write. The authors explain that they detected polarized dust with a 6 sigma significance associated with the brighter, western nucleus. Six Sigma is a very strong detection, indicating a significant level of polarization created by powerful magnetic fields. For Arp 220 to be undergoing starburst activity, a lot of cold gas needs to be concentrated in the starburst regions. However, starburst activity means a lot of young stars are forming. Young stars generate a lot of heat that disperses gas, creating an obstacle for continued star formation. “To stop this happening, you need to add something to hold it all together – a magnetic field in a galaxy, or the lid and weight of a pressure cooker,” said lead author Clement in a press release. NASA/ESA/CSA/STScI “This is the first time we’ve found evidence of magnetic fields in the core of a merger,” Clements said, “but this discovery is just a starting point. We now need better models to see what’s happening in other galaxy mergers.” Astronomers have long been puzzled by starburst galaxies, especially their unusually high star formation rate (SFR). When galaxies merge and become starburst galaxies, they appear to convert gas into stars more efficiently than standalone galaxies. Astrophysicists have theorized about this property of starburst galaxies and what could cause it. Previous theoretical models have suggested that magnetic fields could help restrict the gas from dissipating, driving the starburst activity. However, this is the first time scientists have observed these fields. This figure from the study shows the polarization angle on the left and the magnetic field angle on the right. “We detect polarized dust emission in Arp220 for the first time, with a peak polarized flux intensityof 2.7 +/- 0.45 mJy close to the position of the western nucleus,” the authors write. The ellipses represent the rotating molecular disks, with the white crosses representing the positions of the nuclei. Image Credit: Clements et al. 2025. According to study co-author Qizhou Zhang, also from the CfA, the magnetic fields do more than suppress the dispersal of star-forming gas. “Another effect of the magnetic field is that it slows down the rotation of gas in the disks of merging galaxies. This allows the force of gravity to take over, pulling the sluggish gas inward to fuel starbursts,” said Zhang. “The SMA has been one of the leading telescopes for high angular resolution observations of magnetic fields in molecular clouds in the Milky Way. It’s great to see that this study breaks new ground by measuring magnetic fields in merging galaxies.” In contrast with observations of other nearby galaxies, the direction of the magnetic fields doesn’t seem to correspond with galactic outflow directions. There are some other critical findings regarding the orientation of Arp 220’s magnetic fields. “Dust emission polarization is oriented roughly perpendicular to the molecular disk in the western nucleus,” the authors write. The polarization of dust emission is directly related to the orientation of the magnetic field, and this perpendicular orientation indicates that the magnetic field is oriented to the plane of the galactic disk. However, the magnetic field could be in the process of being reordered as the pair of nuclei interact. This points out how complex the merger environment is and how the magnetic fields are affected. Finding these magnetic fields in Arp 220 strongly indicates that they’re behind the unexpected starburst activity. But it’s only one data point. A larger sample is needed to reaffirm these findings. The research team’s next step is to aim ALMA, the SMA’s big brother, at other galaxies like Arp 220 to see if they also have these magnetic fields. “While the observations described here deal with just a single target, the nearest and brightest ULRG, Arp220, they suggest that magnetic fields may play a significant role in the processes underway in the innermost regions of major mergers,” the authors explain in their paper’s conclusion. “Observations insearch of dust polarization in the inner regions of other local ULIRGs and other DSFGs (Dusty Star-Forming Galaxy) are thus likely to bring new insights into these objects and how they evolve.” Press Release: Astronomers Detect Missing Ingredient in Cooking Up Stars New Research: Polarized Dust Emission in Arp220: Magnetic Fields in the Core of anUltraluminous Infrared Galaxy The post Star Formation Might Depend on Galactic Magnetic Fields appeared first on Universe Today.

Yet another warning sign.

Politics RFK Jr. Is Treating the American People Like Adults Donald Trump’s HHS pick is not coming for Western medicine or ultra-processed food, but restoring Americans’ control over their own health. Credit: Juli Hansen/Shutterstock After two days of confirmation hearings, Robert F. Kennedy Jr. is likely to be the next U.S. Secretary of Health and Human Services—but there’s no reason to clutch your canola oil just yet.  Senators threw buzzwords like “conspiracy theories” and “anti-vaccine” at Kennedy in Wednesday’s Senate hearing. Rhode Island’s Democratic Senator Sheldon Whitehouse told Kennedy, “You frighten people.” Democratic Senator Ron Wyden of Oregon called Kennedy’s books on vaccines “junk science.”  Kennedy made it very clear: He is not coming for our food or vaccines.  “I don’t want to take food away from anybody. If you like a McDonald’s cheeseburger and Diet Coke–which my boss loves–you should be able to get them. If you want to eat Hostess Twinkies, you should be able to do that,” Kennedy said in his hearing. “But you should know what the impacts are on your family and on your health.” This is not a controversial take. Regardless of personal health opinions, the triple vaccinated and the raw milk–drinkers alike have the right to question the foods and medicines they consume and make their own informed choices accordingly.  Kennedy has somewhat walked back his claims on vaccines, despite having previously written books about their potential harmful effects and spoken out against them in podcasts. He asserted throughout the hearing that he is not anti-vaccine and that vaccines “play a critical role in healthcare.”  “I support the measles vaccine, I support the polio vaccine, I will do nothing as HHS Secretary that makes it difficult or discourages people from taking either of those,” Kennedy said in response to Senator Wyden’s accusations that Kennedy is anti-vaccine.  Thanks to vaccines, Americans aren’t dying from preventable diseases. But now they’re just dying slower deaths. One in five American adults is obese, and over half of all Americans have one or more chronic diseases, many of which are preventable through a healthy diet and regular exercise. As Kennedy noted in the hearing, 40 percent of American children—what should be the healthiest population—are afflicted with chronic illnesses. Around one in 10 Americans struggles with infertility. We can no longer deny that Americans have become a very sick people.  We cannot underestimate the role food has to play in our rising health problems. Seed oils—about which Kennedy has been outspoken—make up 8–10 percent of the American’s daily diet (given an average 2,000 calorie diet that would be around 160-200 calories, equal to 1–2 tablespoons of oil consumed every day). These inflammatory oils found in most restaurants and many processed foods are linked to colorectal cancers, which are on the rise among young adults. Food dyes and preservatives banned in Europe are also known to be dangerous when consumed in high enough quantities. We ought to be concerned.  With all this mounting scientific evidence supporting some of Kennedy’s claims, it’s time the American public at last joins him and all the others questioning the FDA’s assurances that our food and medicine are “safe.”  As prominent as Kennedy has been in the health and wellness world, it does not start or end with him. It didn’t take Kennedy to wake people up to the dangers of our food and medicine. We already knew processed foods were harmful; hence diet trends like the Mediterranean, raw vegan, and carnivore diets. Patients and even medical providers were already questioning the necessity of administering nearly two dozen shots in a child’s first year of life. The “crunchy” influencers of social media were already dispersing research and healthier recipes to concerned housewives. This ball has been rolling for quite some time.  Despite what left-leaning media outlets warn, RFK Jr. is not about to eradicate Western medicine and ultra-processed foods. But people will be more informed of their effects. Households will switch to cooking with butter and healthier oils. Parents will research the medicines and foods they give their children. Everyone will have access to their favorite vaccines, and Doritos will stay on grocery store shelves. Even if we remain a physically sick nation, it’ll have to be of our own free choice—not because we blindly trusted doctors and the FDA. At the very least, people will have access to enough information to think for themselves. And that’s perhaps the greatest feat Kennedy could achieve for the American people.  The post RFK Jr. Is Treating the American People Like Adults appeared first on The American Conservative.
