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

Published

on

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.

Quarterhill Awarded High-Speed Weigh-In-Motion Prescreening Contract in Belgium

Published

on

By

The new WIM station will assist Brussels Mobility in achieving its goals of improving road safety and creating a fair regulatory environment by reducing the number of overloaded vehicles on the roads of the Brussels region.Traffic data provided by the system will support Brussels Mobility’s mission to foster economic growth and improve quality of life through the development of transport infrastructure.

TORONTO, Jan. 10, 2025 /PRNewswire/ – Quarterhill Inc. (“Quarterhill” or the “Company”) (TSX: QTRH) (OTCQX: QTRHF), announced today a contract to provide weigh-in-motion (“WIM”) technology to Brussels Mobility through a joint project with Belgium-based technology integrator Jacops NV (“Jacops”). Quarterhill will be responsible for the design and supply of the WIM subsystem, technical support, and training. Quarterhill will also provide Jacops with the software necessary for commercial vehicle monitoring and enforcement.

Quarterhill will supply the WIM system for the Brussels-Capital Region weigh station, which will be used to pre-select overloaded vehicles for enforcement. The dynamic weighing station will promote and improve the efficiency of inspections by screening vehicles at highway speeds in advance of the law enforcement inspection site. In addition, the weigh station will generate data that provides an accurate, real-time picture of the vehicles on the E19 highway.

The system’s goal is to reduce the number of overloaded vehicles on the Brussels Region’s roads. Overloading causes many problems, such as rapid road deterioration, more serious accidents, and unfair competition between transport companies. Quarterhill’s technology mitigates these issues by screening for overweight vehicles while optimizing the use of enforcement resources.

“We are excited at the prospect of introducing our advanced enforcement technology to Brussels Mobility and expanding our presence in Europe,” said Chuck Myers, CEO of Quarterhill. “Together with Jacops, we will deploy a state-of-the-art high-speed WIM system that will make Belgian roads safer and more sustainable. We have a longstanding relationship with Jacops as a customer for our microwave sensor products, and this project demonstrates how having a broad portfolio of traffic technologies and established relationships with traffic system integrators leads to further opportunities.”

The weigh station will monitor four lanes of one-way traffic on the highway and record data on vehicle classification and vehicle tax without impeding traffic. An overview camera provides images to help enforcement personnel clearly identify vehicles flagged by the system. An Automated Number Plate Reader system will photograph, recognize, store, process, and transmit the number plates of vehicles approaching the dynamic weighing station.

Quarterhill’s iSINC WIM controller was selected for the project as it offers preselection of overweight vehicles, creates comprehensive vehicle records, classifies vehicles, and meets the desired standards for continual uptime monitoring and ease of service. iSINC’s versatility allows it to control a wide array of sensors, cameras, dimensioning systems, communication systems, and custom equipment.

WIM sensors that comply with the accuracies outlined in the Nmi International WIM standard Specification and test procedures for WIM Systems will be installed at the site. The WIM sensors meet the lane width specifications and provide high durability, stable output over time, and IP68 water resistance.

Quarterhill will advise Jacops on the design and placement of the WIM system components to ensure optimal operation, including onsite technical support for installation, testing, and initial calibration. Quarterhill will also provide Jacops with thorough training on the WIM components and system calibration. Over the 2-year warranty period, Quarterhill will provide remote diagnostics and technical support to ensure continuous uptime and optimal performance.

“This project shows that Quarterhill’s technology is well suited to the precise needs of European agencies. We are set to elevate road safety and integrity in the region, reinforcing our expanding footprint in this important market,” stated Heimo Haub, Managing Director, Quarterhill Europe.
