Chandra researchers analyzed the activity at the center of the Perseus cluster and concluded that it produces a very, very low B - flat.

Last September researchers using the Chandra X-ray Observatory detected sound waves blaring from a distant black hole.

Using data from a trio of orbiting X-ray telescopes, NASA's Chandra X-ray Observatory and Swift Satellite as well as ESA's XMM - Newton, researchers found evidence of a massive «tidal disruption event» (TDE).

«This chicken - and - egg problem of what was there first, the galaxy or the black hole, has been pushed all the way to the edge of the universe,» Yale University astrophysicist Kevin Schawinski said in a June 15 press conference at NASA Headquarters in Washington, D.C. Schawinski was part of a team of researchers that used two renowned orbiting observatories, the Hubble Space Telescope and the Chandra X-Ray Observatory, to identify a population of black holes in galaxies at redshift 6, which corresponds to a time about 950 million years after the big bang.

The researchers drew on deep x-ray imagery from Chandra, built up over four million seconds (46 days) of telescope exposure time, to identify the ancient black holes.

Along with Hubble, which shows where the old and the new stars are, the researchers used the Galaxy Evolution Explorer (GALEX), the Herschel Space Observatory, the Spitzer Space Telescope, the Chandra X-ray Observatory, the X-ray Multi-Mirror Mission (XMM - Newton), the National Radio Astronomy Observatory (NRAO)'s Jansky Very Large Array (JVLA), the National Optical Astronomy Observatory (NOAO)'s Kitt Peak WIYN 3.5 meter telescope, and the Magellan Baade 6.5 meter telescope.

Co-authors are former Rice postdoctoral researcher Tharangattu Narayanan, now at the CSIR - Central Electrochemical Research Institute, Karaikundi, India; Chandra Sekhar Tiwary, who has a research appointment at Rice and is a scientist at the Indian Institute of Science, Bangalore, India; and Rice alumna Karen Lozano, a professor of mechanical engineering, and Mircea Chipara, an assistant professor of physics and geology, both of the University of Texas Pan American, Edinburg, Texas.

For this study, OU researchers used the NASA Chandra X-ray Observatory at the Smithsonian Astrophysical Observatory.

Then last year, researchers using NASA's orbiting Chandra X-ray Observatory took another look at the object and realized that its boundaries had expanded by 16 % in the intervening 22 years.

To determine just how far away they are, researchers will combine the information from the Hubble images with observations taken by NASA's Spitzer and Chandra space telescopes, which see in infrared and x-ray light, respectively.

Chandra has put those doubts to rest with images of what researchers call «the richest field of x-ray sources ever obtained.»

Walton and several other Caltech researchers analyzed the data from NuSTAR and a second NASA X-ray telescope, Chandra, to rule out about 25 different X-ray sources, finally settling on a ULX known as M82X - 2 as the source of the flashes.

The researchers found that the Chandra data from Sgr A * did not support theoretical models in which the X-rays are emitted from a concentration of smaller stars around the black hole.

In addition the researchers enjoyed unprecedented observation time of 3 megaseconds, almost five weeks, with the Chandra X-ray Observatory.

Researchers using the Chandra X-ray telescope have discovered a group of black holes consuming massive amounts of matter.

The international team of researchers used data from three orbiting X-ray telescopes — NASA's Chandra X-ray Observatory and Swift Satellite as well as the European Space Agency's XMM - Newton.

Researchers said that Chandra and European Space Agency's XMM - Newton Observatory detected diffuse X-ray emission that came from a large amount of hot gas, which, according to astronomers, is a major defining feature of a true galaxy cluster.

Other researchers on the study were Richard Dargusch, Jennifer L. Ehren and Chandra Chiruta, of the Salk Institute.

«Other missions like NASA's Chandra X-ray Observatory and the European Space Agency's XMM - Newton looked at the Perseus cluster before, but their instruments didn't have sufficient energy resolution to study the dynamics of the intergalactic medium,» said Stanford University postdoctoral researcher Irina Zhuravleva in a press release.

Postdoctoral researcher and co-first author Shilpi Chandra, Ph.D., and her colleagues were particularly interested in MAIT cells (short for mucosal - associated invariant T cells) and their brethren, invariant natural killer T (iNKT) cells.

The inset boxes contain Chandra (top) and Hubble (bottom) images of one of two candidate seeds, where the properties in the data matched those predicted by sophisticated models produced by researchers of the direct - collapse mechanism.

Although much of the published research on educational robotics focuses on informal, out - of - school time settings, researchers and practitioners have begun to explore the possibilities of using LEGO Robotics in formal K - 12 STEM education settings (Mills, Chandra, & Park, 2013; Park, 2015; Taylor, 2016).
