  • A Newly Discovered ‘Einstein’s Cross’ Reveals the Existence of a Giant Dark Matter Halo

    The gravitational lensing not only splits the light source, but magnifies it, allowing a detailed view of the light source behind the lens. Thanks to this, the team says that HerS-3 appears to be a bright starburst galaxy—a galaxy undergoing explosive star formation—and was formed at a time when star formation was at its peak throughout the universe. HerS-3 also has a tilted, rotating disk, from the center of which gas is gushing out at a furious rate, the team say.

    “Thanks to this natural telescope, we can zoom into regions 10 times smaller than the Milky Way, almost 12 billion light-years away, and in the process infer hidden matter in the light-of-sight,” said Hugo Mesias, a coauthor of the paper, in a statement.

    A Giant Dark Matter Halo Revealed

    At first glance, the Einstein’s cross of HerS-3 appears to have been created solely by gravitational lensing generated by the four giant galaxies located between HerS-3 and Earth. However, using a precise model of gravitational lensing, the team found that the observable mass of these four giant galaxies is insufficient to explain the arrangement of the five images of the cross: their mass is simply not great enough to produce the visual effect seen.

    “The only way to reproduce the remarkable configuration we observed was to add an invisible, massive component: a dark matter halo at the center of the galaxy group,” said lead author Pierre Cox, from the Institut d’Astrophysique de Paris.

  • Ruth Ashton Taylor, trailblazing TV journalist, dies at 101

    Ruth Ashton Taylor, trailblazing TV journalist, dies at 101

    Ruth Ashton Taylor, the first female television newscaster in Los Angeles and one of the first in the country, died Thursday in Northern California, her family announced. She was 101.

    A Los Angeles-area native, Taylor trailblazed a 50-year career in journalism, during which she interviewed the likes of Albert Einstein and J. Robert Oppenheimer, worked with industry icons including Edward R. Murrow and earned a star on the Hollywood Walk of Fame.

    “She was certainly that woman out there doing something that none of us saw other women doing at the time,” Susan Conklin, one of Taylor’s daughters, said in an interview with The Times.

    Taylor was born in Long Beach in 1922 and graduated from Long Beach Polytechnic High School and Scripps College in Claremont before heading east to attend Columbia University for graduate school.

    Almost immediately after graduating from Columbia, Taylor was hired to join a CBS documentary team led by Murrow, Conklin said.

    Despite being in her early 20s at the time, Taylor proved to be a fearless reporter.

    “She was trying to do a piece on the peacetime uses of nuclear energy and she went and she found Dr. Einstein,” Conklin said.

    Taylor had been attempting to contact Einstein for some time before she traveled unannounced to Princeton University, where he was working.

    Taylor happened upon Einstein as he was walking down a hill.

    She introduced herself.

    “He said, ‘Ah! The broadcasting lady,’” Taylor recalled in a set of interviews done for the Washington Press Club Foundation.

    Taylor returned to Los Angeles in 1951 and was hired as the West Coast’s first female television reporter at KNXT, now KCBS.

    She left journalism for a short time in the late 1950s before returning to KNXT in 1962, where she spent the rest of her career before retiring in 1989.

    Taylor covered an array of topics during her career, and hosted a variety of segments and shows.

    During one fire, Taylor recalled, a Los Angeles County fire chief said, “This is the first time I’ve ever been interviewed on a fire line by a woman.”

    “But not the last,” Taylor replied.

    After officially retiring from KCBS, Taylor continued to work on retainer for the broadcaster into the 1990s.

    Among the honors she received in acknowledgment of her decades-long career was a Lifetime Achievement Emmy.

    Despite Taylor’s demanding work schedule, Conklin said her mother was always there for her family.

    “Work was really important to her,” Conklin said. “She worked hard, but I never felt like she forgot she had kids. We still came first for her.”

    “She just showed up as a mom … and then showed up as a grandmother and showed up as a great-grandmother,” Conklin added.

    Taylor is survived by her daughters Susan, Sadie and Laurel Conklin, her stepson John Taylor, a grandson and granddaughter-in-law and a great-grandson.

  • Einstein and Oppenheimer’s Real Relationship Was Cordial and Complicated

    Einstein and Oppenheimer’s Real Relationship Was Cordial and Complicated

    [ad_1]

    There’s a gutting scene midway through Oppenheimer that finds Cillian Murphy’s J. Robert Oppenheimer at one of his lowest moments. Despite the scientist’s service to his country, he’s being accused of harboring treasonous sympathies; an unofficial trial with a foregone conclusion is dragging him through the mud. Outside his home in Princeton, he encounters a colleague: Albert Einstein (Tom Conti), who doesn’t seem to get why his fellow physicist is lying down and taking it. 

    If this is the reward the American government gives Oppenheimer after the years he spent developing the nuclear bomb that ended World War II, Einstein tells him in the film, Oppenheimer should simply “turn his back” on America. (It’s what Einstein was forced to do to his homeland of Germany, after all—and for understandable reasons, he would never trust governments or politicians.) What the essentially stateless Einstein doesn’t understand is that for New York City–born Oppenheimer, this simply isn’t an option. “Damnit,” he replies, “I happen to love this country.”

    Like many of the details in Christopher Nolan’s script, both lines of dialogue come straight from Oppenheimer’s source material, Kai Bird and Martin Sherwin’s biography American Prometheus. (Though Oppenheimer’s memorable reply is actually lifted from a different exchange.) The scene is a neat illustration of how these two scientific giants both mirrored and opposed one another. Einstein only has a handful of scenes in Oppenheimer, but each of them packs a similar punch—particularly another (fictionalized) Princeton meeting that the film keeps coming back to, revealing its full significance only in the movie’s final moments.

    It shouldn’t be surprising to learn that the man whose name has become synonymous with “genius” is only a supporting character in Nolan’s film. Though it was Einstein’s letter to President Roosevelt that convinced FDR to begin a nuclear weapons program, Einstein was not involved in the Manhattan Project. (The government deemed him a security risk due to his left-leaning politics—though it cleared Oppenheimer, despite his various ties to Communists and Communist sympathizers.) 

    And though he and Oppenheimer both lived and worked at Princeton after the war—specifically at its Institute for Advanced Study, where Oppenheimer served as director from 1947 to 1966—they were not particularly close friends. While they had known each other for years before he came to Princeton and he respected Einstein—who wouldn’t?—Oppenheimer thought of his predecessor “as a living patron saint of physics, not a working scientist,” Bird and Sherwin write. “In the last years of Einstein’s life, the last twenty-five years, his tradition in a certain sense failed him,” Oppenheimer would write in 1965, in a  lecture later published in the New York Review of Books

    The older physicist was skeptical of quantum theory, which Oppenheimer would advance, and didn’t believe black holes could possibly exist. As shown in Oppenheimer, the younger physicist helped to prove they do. (In a paper published the same day Hitler invaded Poland!) Though Oppenheimer thought he was essentially old-fashioned, “Einstein eventually acquired a grudging respect for the new director” of the Institute, write Bird and Sherwin, “whom he described as ‘an unusually capable man of many-sided education.’ But what he admired about Oppenheimer was the man, not his physics.” 

    That said, the biographers indicate Einstein and Oppenheimer did still enjoy each others’ company. They relay a charming anecdote about the two that didn’t make it into Oppenheimer but would’ve been a gas to see. In 1948, they write, “knowing Einstein’s love of classical music, and knowing that his radio could not receive New York broadcasts of concerts from Carnegie Hall, Oppenheimer arranged to have an antenna installed on the roof of Einstein’s modest home at 112 Mercer Street. This was done without Einstein’s knowledge—and then on his birthday, Robert showed up on his doorstep with a new radio and suggested that they listen to a scheduled concert. Einstein was delighted.” 

    Years later, when Oppenheimer was targeted for his past Communist ties and stripped of his security clearance, Einstein was firmly on his colleague’s side—even if he didn’t understand Oppenheimer’s response. “The trouble with Oppenheimer is that he loves a woman who doesn’t love him—the United States government,” he told a friend, per Bird and Sherwin. “The problem was simple: All Oppenheimer needed to do was to go to Washington, tell the officials that they were fools, and go home.” Einstein was (ahem) smart enough to keep those views private. Publicly, he expressed his support in a more palatable manner: “I admire him not only as a scientist but also as a great human being,” he told the press.
