Dr Ragadeepika Pucha, a postdoctoral researcher of Indian origin, and her team of scientists discovered 2,500 likely active black holes in small galaxies. Her team examined previously provided data by the Dark Energy Spectroscopic Instrument (DESI) , a celestial device in Arizona measuring the results of dark matter in the universe’s expansion.
Along with identifying the active black holes they also uncovered the samples of 300 new intermediate-mass black holes, adding the most effective findings to the data collection. The discovery tripled the present census of high-energy galactic centers and doubled the amount of intermediate black holes, as per the NOIRLab press release.
More than 900 researchers from over 70 institutions collaborated on the DESI project handled by DOE’s Lawrence Berkeley National Laboratory. Deepika led the team that acquired an unprecedented dataset of 410000 galaxies’ spectra including about 115000 dwarf galaxies.
The revelation of the black holes made the team hyped with happiness and exhilaration. While the existence of supermassive black holes is confirmed, the reason for their formation has not yet been uncovered by scientists.
While the theories assumed that these black hole substances would be found in the middle of dwarf galaxies, in reality, many of them were found in huge galaxies. In order to make sense of the cosmos, explorers must first comprehend the behavior and evolution of dwarf galaxies. “I am interested in learning about the formation and evolution of dwarf galaxies,” Pucha said. To arrive at a current outcome, she logged onto a supercomputer and spent the last four years searching through the vast amount of data.
The dual success will not only add substance to our research and data but will also open up new avenues for future studies surrounding the earliest black hole theories and discoveries.
