Findings from IXPE Data Reveal Key Insights on Corona Around Black Holes

WASHINGTON, Nov. 22, 2024 /PRNewswire/ — Groundbreaking research using data from NASA’s Imaging X-ray Polarimetry Explorer (IXPE) mission has revealed new insights into the shape and properties of a black hole’s corona, a key structure surrounding black holes. Led by Universities Space Research Association’s (USRA) postdoctoral researcher, Lynnie Saade, at USRA’s Science and Technology Institute, these findings were recently published in The Astrophysical Journal and represent a significant advance in our understanding of black hole environments. The work was conducted at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Many black holes are encircled by accretion disks —turbulent whirlpools of gas and debris, —and they also feature superheated coronas. These coronas are dynamic regions of plasma that are responsible for most X-ray emissions from black holes though scientists have only theoretical insights into their behavior. This latest discovery offers the first glimpse into the shape of these coronas, potentially deepening our understanding of how they help to generate the energy released when the black holes absorb materials.

“Scientists have long speculated on the makeup and geometry of the corona,” said Lynnie Saade. “Is it a sphere above and below the black hole, or an atmosphere generated by the accretion disk, or perhaps plasma located at the base of the jets?”

Results from the IXPE, which specializes in X-ray polarization, help map the shape and structure of coronas. IXPE observes X-rays, and studies objects that are not just small, but also very distant. X-ray polarization is needed “to determine the geometry of these objects which are too small and distant to image.”

According to Lynnie Saade, “IXPE provides the means to study the black hole’s accretion geometry, or the shape and structure of its accretion disk and related structures, including the corona.”

IXPE demonstrated that, among all black holes for which coronal properties could be directly measured via polarization, the corona was found to be extended in the same direction as the accretion disk – providing, for the first time, clues to the corona’s shape and clear evidence of its relationship to the accretion disk. The results rule out the possibility that the corona is a compact region above and below the black hole or at the base of a relativistic jet.

This research has significant implications. With the increasing availability of data on the shape of the corona, scientists can refine their models and develop a deeper understanding of its nature and behavior.

IXPE has not observed all black holes. This research has only studied 12 black holes, among them Cygnus X-1 and Cygnus X-3, stellar-mass binary black hole systems about 7,000 and 37,000 light-years from Earth, respectively, and LMC X-1 and LMC X-3, stellar-mass black holes in the Large Magellanic Cloud more than 165,000 light-years away.

Stellar mass black holes typically have a mass roughly 10 to 30 times that of Earth’s Sun, whereas supermassive black holes may have a mass that is millions to tens of billions of times larger. Despite these vast differences in scale, IXPE data suggests both types of black holes create accretion disks of similar geometry. Future research is needed to explore more black holes and advance our understanding of the corona.

District-wide rollout brings project-based financial literacy and professional mentorship to Manhattan’s 50 public high schools, building on a successful pilot at Jacqueline Kennedy Onassis High School

NEW YORK, Oct. 26, 2026 /PRNewswire/ — Louis Hernandez Jr.’s Foundation For A Bright Future (“For A Bright Future,” “FABF”), a 501(c)(3) nonprofit organization dedicated to expanding educational opportunity for underserved youth, today announced the district-wide expansion of its NextGen Finance Lab program into the Manhattan High School District. In partnership with the Manhattan High School District Team, under the supervision of Superintendent Gary Beidleman, FABF will launch the program’s first cohort of 8 high schools this fall, with plans to bring the NextGen Finance Lab to additional Manhattan high schools in the semesters that follow as part of a phased, district-wide rollout.

“At Jacqueline Kennedy Onassis, we saw firsthand what this program can do. Our students left Pitch Like A Dragon more confident, more articulate, and more prepared to manage their own financial futures than I’ve seen from any other initiative we’ve run. I’m proud that the model our students and teachers helped build is now reaching classrooms across Manhattan,” said Manuel A. Ureña, Principal, Jacqueline Kennedy Onassis High School.

The NextGen Finance Lab is a project-based financial literacy program that integrates the Dave Ramsey Financial Literacy curriculum with FABF’s FinTech mentorship ecosystem. Throughout the program, students build core skills in budgeting, saving, debt elimination, investing, and entrepreneurship, while working directly with FinTech industry professionals who share real-world perspective on banking, digital wallets, investing, and career pathways in financial technology. The program culminates in “Pitch Like A Dragon,” a school-level and district-level competition in which student teams pitch original business and FinTech concepts to a panel of industry leaders, venture capitalists, and New York City business professionals, with scholarship awards presented to top teams.

“This expansion is proof of what’s possible when a nonprofit, a school district, and industry partners commit to the same goal. Everything we’re scaling today started as a pilot at Jacqueline Kennedy Onassis High School, where educators and students helped shape the curriculum and the ‘Pitch Like A Dragon’ event structure now being adopted by seven more schools this fall. That’s how one school’s success becomes a lasting pathway for thousands of students across Manhattan,” said Gina Rogoto, SVP, Operations and Programs, For A Bright Future Foundation.”This expansion demonstrates the collective impact achievable through aligned partnerships. The model shaped at Jacqueline Kennedy Onassis (JKO) High School now serves as a lasting foundation for advancing financial literacy for thousands of students across Manhattan,” said Gina Rogoto, SVP, Operations and Programs, FABF. The success at JKO High School, now fueling district‑wide deployment, was strengthened by the guidance of FABF’s Consultant in Academic Affairs and former Senior Deputy Chancellor of the NYC Department of Education, whose deep expertise helped shape a program adaptable to each school’s unique vision and academic priorities.

FABF and the Manhattan High School District Team have confirmed the following schools for the initial launch cohort:

Leadership and Public Service High SchoolJacqueline Kennedy Onassis High SchoolHigh School for Law and Public ServiceMurry Bergtraum High School for Business CareersHigh School of Fashion IndustriesHudson High School of Learning TechnologiesMott Hall High School: Finance Lab ProgramFood and Finance High School

FABF’s long-term goal is to bring the NextGen Finance Lab to all 50 high schools in the Manhattan District, expanding in phased cohorts over the coming semesters.

“As someone who spent a career in financial services, I know how much of a difference it makes when young people are exposed to these concepts early. This program doesn’t just teach students about money; it gives them the confidence to pitch real ideas, take feedback, and think like entrepreneurs,” said Benson Porter, Program Chairman, NextGen Finance Lab, FABF.
